Cat
Pet Animal
Lifespan: 2 – 16 years (In the wild)
Family: Felidae
Order: Carnivora
Scientific name: Felis catus
Gestation period: 58 – 67 days
Kingdom: Animalia
Cat, (Felis catus), also called house cat or domestic cat, domesticated member of the family Felidae, order Carnivora, and the smallest member of that family.
Like all felids, domestic cats are characterized by supple low-slung bodies, finely molded heads, long tails that aid in balance, and specialized teeth and claws that adapt them admirably to a life of active hunting.
Cats possess other features of their wild relatives in being basically carnivorous, remarkably agile and powerful, and finely coordinated in movement.
It is noteworthy that the ancestors of the other common household pet, the dog, were social animals that lived together in packs in which there was subordination to a leader, and the dog has readily transferred its allegiance from pack leader to human master.
The cat, however, has not yielded as readily to subjugation. Consequently, the house cat is able to revert to complete self-reliance more quickly and more successfully than most domesticated dogs. For an account of the relationship of the family of cats to other carnivores, see carnivore.
General characteristics
Coordination and musculature
Cats are among the most highly specialized of the flesh-eating mammals. Their brains are large and well developed. Cats are digitigrade; that is, they walk on their toes.
Unlike the dog and horse, the cat walks or runs by moving first the front and back legs on one side, then the front and back legs on the other side; only the camel and the giraffe move in a similar way. The cat’s body has great elasticity.
Because the vertebrae of the spinal column are held together by muscles rather than by ligaments, as in humans, the cat can elongate or contract its back, curve it upward, or oscillate it along the vertebral line.
The construction of the shoulder joints permits the cat to turn its foreleg in almost any direction. Cats are powerfully built animals and are so well coordinated that they almost invariably land on their feet if they fall or are dropped.
Teeth
The cat’s teeth are adapted to three functions: stabbing (canines), anchoring (canines), and cutting (molars). Cats have no flat-crowned crushing teeth and therefore cannot chew their food; instead, they cut it up.
Except for the canines and molars, the cat’s teeth are more or less nonfunctional; most of the cheek teeth do not even meet when the mouth is closed.
The dental formula in all cats, for either side of both upper and lower jaws, is incisors 3/3, canines 1/1, premolars 3/2, and molars 1/1. The total number of teeth is 16 in the upper jaw and 14 in the lower.
Primary, or milk, teeth number 24; these are replaced by the permanent teeth at about five months. Each half of the jaw is hinged to the skull by a transverse roller that fits tightly into a trough on the underside of the skull, making grinding movements impossible even if the cat had teeth suitable for grinding.
Claws
There is a remarkable mechanism for retracting the cat’s claws when they are not in use. The claw is retracted or extended by pivoting the end bone of the toe, which bears the claw, over the tip of the next bone.
The action that unsheathes the claws also spreads the toes widely, making the foot more than twice as broad as it normally is and converting it into a truly formidable weapon.
This claw-sheathing mechanism is present in all species of the cat family except the cheetah. Although there are no nerve endings in the nail itself, blood capillaries are present in the inner part.
Senses
Cats are generally nocturnal in habit. The retina of the cat’s eye is made extra sensitive to light by a layer of guanine, which causes the eye to shine at night in a strong light.
The eyes themselves, large with pupils that expand or contract to mere slits according to the density of light, do not distinguish colours clearly. Cats have a third eyelid, or nictitating membrane, commonly called the haw. Its appearance is used frequently as an indicator of the cat’s general state of health.
The cat’s sense of smell, particularly well developed in the adult, is crucial to its evaluation of food, so that a cat whose nasal passages become clogged as a result of illness may appear to lose its appetite completely. Cats can distinguish the odour of nitrogenous substances (e.g., fish) especially keenly.
The sense of touch is acute in cats. The eyebrows, whiskers, hairs of the cheek, and fine tufts of hair on the ears are all extremely sensitive to vibratory stimulation.
The functions of the whiskers (vibrissae) are only partially understood; however, it is known that, if they are cut off, the cat is temporarily incapacitated. The toes and paws, as well as the tip of the nose, are also very sensitive to touch.
Cats also have an acute sense of hearing. Their ears contain almost 30 muscles (compared with 6 in humans); as a result, they can turn them many times more quickly in the direction of a sound than can a dog.
The ears of cats are receptive to ultrasonic frequencies up to 85,000 vibrations per second, greatly exceeding the hearing capabilities of dogs, which register 35,000 vibrations per second.

HOW TO A COW TOTAL HISTORY
Cow
Farm Animal
Cattle, or cows, are the most common type of large domesticated ungulates. They are a prominent modern member of the subfamily Bovinae, are the most widespread species of the genus Bos, and are most commonly classified collectively as Bos taurus.
Lifespan: 18 – 22 years
Scientific name: Bos taurus
Gestation period: 283 days
Family: Bovidae
Class: Mammalia
Mass: Male: 1,100 kg (Adult, Bull), Female: 720 kg (Adult, Cow)
Cow, in common parlance, a domestic bovine, regardless of sex and age, usually of the species Bos taurus. In precise usage, the name is given to mature females of several large mammals, including cattle (bovines), moose, elephants, sea lions, and whales.
Domestic cows are one of the most common farm animals around the world, and the English language has several words to describe these animals at various ages.
A baby cow is called a calf. A female calf is sometimes called a heifer calf and a male a bull calf. A heifer is a female that has not had any offspring. The term usually refers to immature females; after giving birth to her first calf, however, a heifer becomes a cow.
An adult male is known as a bull. Many male cattle are castrated to reduce their aggressive tendencies and make them more tractable. Young neutered males, which are primarily raised for beef, are called steers or bullocks, whereas adult neutered males, which are usually used for draft purposes, are known as oxen.
A group of cows, cattle, or kine (an archaic term for more than one cow) constitutes a herd. English lacks a gender-neutral singular form, and so “cow” is used for both female individuals and all domestic bovines.
The size and weight of a cow is highly dependent on the breed. Mature males weigh 450–1,800 kg (1,000–4,000 pounds) and females weigh 360–1,100 kg (800–2,400 pounds).
Both males and females have horns, and although these may be short in many breeds, they can grow to be spectacularly large, such as in Texas longhorns and African Ankole-Watusi cows.
Some breeds are genetically polled (hornless), and many other cows may be dehorned (that is, have their horn buds destroyed) at young age to make them easier to transport and safer to work around. Cows are renowned for their large milk-producing (mammary) glands known as udders, which possess four teats (nipples).
Biology Of Cow
Anatomy
Cattle are large quadrupedal ungulate mammals with cloven hooves. Most breeds have horns, which can be as large as the Texas Longhorn or small like a scur. Careful genetic selection has allowed polled (hornless) cattle to become widespread.
Digestive system
Cattle are ruminants, meaning their digestive system is highly specialized to allow the use of poorly digestible plants as food.
Cattle have one stomach with four compartments, the rumen, reticulum, omasum, and abomasum, with the rumen being the largest compartment. The reticulum, the smallest compartment, is known as the "honeycomb".
The omasum's main function is to absorb water and nutrients from the digestible feed. The omasum is known as the "many plies". The abomasum is like the human stomach; this is why it is known as the "true stomach"
Cattle are known for regurgitating and re-chewing their food, known as cud chewing, like most ruminants. While the animal is feeding, the food is swallowed without being chewed and goes into the rumen for storage until the animal can find a quiet place to continue the digestion process.
The food is regurgitated, a mouthful at a time, back up to the mouth, where the food, now called the cud, is chewed by the molars, grinding down the coarse vegetation to small particles. The cud is then swallowed again and further digested by specialized microorganisms in the rumen
Gestation and size
The gestation period for a cow is about nine months long. A newborn calf's size can vary among breeds, but a typical calf weighs between 25 to 45 kg (55 to 99 lb). Adult size and weight vary significantly among breeds and sex.
Steers are generally killed before reaching 750 kg (1,650 lb). Breeding stock may be allowed a longer lifespan, occasionally living as long as 25 years. The oldest recorded cow, Big Bertha, died at the age of 48 in 1993.
Reproduction
On farms it is very common to use artificial insemination (AI), a medically assisted reproduction technique consisting of the artificial deposition of semen in the female's genital tract.
It is used in cases where the spermatozoa can not reach the fallopian tubes or simply by choice of the owner of the animal.
It consists of transferring, to the uterine cavity, spermatozoa previously collected and processed, with the selection of morphologically more normal and mobile spermatozoa.
A cow's udder contains two pairs of mammary glands, (commonly referred to as teats) creating four "quarters". The front ones are referred to as fore quarters and the rear ones rear quarters.
Weight
The weight of adult cattle varies, depending on the breed. Smaller kinds, such as Dexter and Jersey adults, range between 272 to 454 kg (600 to 1,000 lb). Large Continental breeds, such as Charolais, Marchigiana, Belgian Blue and Chianina, adults range from 635 to 1,134 kg (1,400 to 2,500 lb).
British breeds, such as Hereford, Angus, and Shorthorn, mature between 454 to 907 kg (1,000 to 2,000 lb), occasionally higher, particularly with Angus and Hereford.
Bulls are larger than cows of the same breed by up to a few hundred kilograms. Chianina bulls can weigh up to 1,500 kg (3,300 lb); British bulls, such as Angus and Hereford, can weigh as little as 907 kg (2,000 lb) to as much as 1,361 kg (3,000 lb).

Tiger
Wild Animal
The tiger is the largest species among the Felidae and classified in the genus Panthera. It is most recognisable for its dark vertical stripes on orangish-brown fur with a lighter underside. It is an apex predator, primarily preying on ungulates such as deer and wild boar.
Scientific name: Panthera tigris
Lifespan: 10 – 15 years (In the wild)
Speed: 49 – 65 km/h (Adult, In Short Bursts)
Height: 70 – 120 cm (Adult, At Shoulder)
Mass: Male: 90 – 310 kg (Adult), Female: 65 – 170 kg (Adult)
Diet: Carnivore
Black and white and orange all over: The beautiful, striped coat and that powerful, mesmerizing gaze make the tiger one of the world’s most revered animals.
It’s a reverence that’s mixed with a bit of fear, an appropriate reaction to a large, well-muscled, swift hunter with inch-long claws and 3-inch-long (7 centimeter) canine teeth.
The tiger is a stalk-and-ambush hunter, and the distinctive stripes are good camouflage in the long grass or wooded forests of their diverse habitat. Dark stripes on a pale background break up the tiger’s outline as it lies in wait for prey to come near.
Tigers can also be black with tan stripes, all white (albino), or white and tan. The “white tigers” found in some zoos are not albino but rather the white-and-tan color variation with blue eyes (true albinos have pink eyes).
Biology Of Tiger
HABITAT AND DIET
There are currently six subspecies of tigers, each living in different habitats: flooded mangrove forests, arid forests, tropical forests, and taiga.
The different subspecies are found in small areas of Asia, India, and Russia. The largest subspecies lives in snowy areas of Russia.
The smallest and darkest subspecies is found farther south, in the jungles of Indonesia. Female tigers are always smaller than males.
Amur or Siberian tiger Panthera tigris altaica: The largest of the tiger subspecies, males can be as long as a station wagon! These tigers also have the palest orange coat and the fewest stripes, to help it blend in with its snow-covered habitat.
As it lives in a very cold climate, the Siberian tiger’s coat grows longer and thicker than other tiger subspecies, and it develops a layer of fat for insulation. There are about 450 Siberian tigers left in their home range of eastern Russia and northeastern China.
Bengal or Indian tiger Panthera tigris tigris: This is the most common subspecies of tiger and is almost as large as the Siberian tiger. About 3,400 Bengal tigers remain in their native habitat of India, Nepal, and Pakistan.
Malayan tiger Panthera tigris jacksoni: This is the subspecies you’ll see at the San Diego Zoo. In the wild, fewer than 200 Malayan tigers remain, found on the Malay Peninsula. Of those, only 80 to 120 are breeding adults.
Sumatran tiger Panthera tigris sumatrae: Even though the Sumatran is the smallest tiger subspecies, it ’s still a pretty big cat.
Imagine a tiger the same length as a school cafeteria table! Its orange coat is darker than other subspecies, as it is native to dark jungle habitat on the island of Sumatra; the sides of the face have longer fur, perhaps as
protection against jungle plants. The Safari Park has a small group of Sumatran tigers, but in the wild there are about 370 remaining.
South China tiger Panthera tigris amoyensis: These tigers are slightly smaller than the Indochinese subspecies. In the 1950s, the Chinese government ordered that these tigers be destroyed because they were viewed as pests.
Today, it is believed that the South China tiger is most likely extinct in the wild.
FAMILY LIFE
Going it alone: Tigers are generally solitary cats, unless a female is caring for her cubs, and maintain a home range that can be several square miles,
depending on habitat and the amount of prey available; males tend to have larger territories than the females. The Siberian tiger has the largest range (more than 4,000 square miles or 10,000 square kilometers have been recorded) as food is scarcer, so the tiger has to travel farther to secure a meal.
Some tigers defend their territory from other tigers while others often share their range.
A female tiger in estrus leaves urine “messages” on trees and other places to let males know of her reproductive status.
Through loud moaning calls, a male and female can find each other for breeding and may stay together for a few days before going their separate ways.
Tiger cubs are born small and helpless, but the mother must leave them alone while she hunts. A female can have a litter of up to seven cubs every two years.
In the wild, the mother could not kill enough prey to feed so many hungry cubs, so usually only two survive. At eight weeks old, cubs join their mother when hunting, and at six months they are ready to learn how to kill cattle, deer, and pigs.
AT THE ZOO
Mesmerizing and gorgeous, but also endangered, our tigers are always a pleasure to watch. Over the years, we have had over 100 Bengal, Siberian, Sumatran, and Malayan tigers born at our two facilities.
The San Diego Zoo is currently home to three male Malayan tigers. The San Diego Zoo Safari Park is home to male Sumatran tigers Denver and Rakan; and females Diana, Majel, Joanne, Cathy, and Debbie.
Our most famous tiger was Blanca, the white Bengal tiger who came to the San Diego Zoo after being confiscated as a cub by the U.S. Customs Service—she was traveling from San Diego to Mexico in the back seat of someone's car! While her owners explained to officials that the cat was returning to a private zoo in Mexico,
young Blanca (she was under three months old at the time) was romping in the back seat and peering out the car's windows. Because special permits are required to transport tigers, the tiger cub was confiscated.
However, with no facilities to keep a tiger, the Customs Service temporarily relocated the cub to the San Diego Zoo's own Children's Zoo, where she soon became a favorite of guests and employees. In March 1992,
she officially became part of the Zoo family. In 1996, she moved to the Safari Park, where she continued to thrive and delight guests with her unusual beauty until her passing in 2012.
Tigers at the Zoo and Safari Park receive a hearty meat-based diet, imaginative enrichment items, and basic behavioral training for wildlife care.
For example, our tigers are taught to “rise up” on their hind legs to allow staff to inspect their bellies and paws, they learn to open their mouths so we can ensure their teeth are healthy,
and they accept blood draws from the base of their tail for laboratory analysis. All this minimizes stress on the animals in the long run, since they do not have to be tranquilized for a trip to the veterinary hospital for every health issue.
CONSERVATION
Tiger cures? There are six subspecies of tiger living today, all highly endangered due to human hunting and encroachment on their forest habitat.
To people of many cultures, the tiger is a symbol of strength and courage. But if tigers are so admired, why are they endangered? For many years, tigers have been hunted for their fur and other body parts, some of which are used in native medicines.
In some cultures, people hunt tigers for sport or to demonstrate their own bravery. Tiger hunting continues today because the body parts can be sold for a lot of money.
Several traditional medicines use tiger parts as a cure for all kinds of illnesses, from pimples to toothaches. These “cures” have never been proven to be effective.
Tigers also suffer from habitat loss. When people move into areas where tigers live, tigers are forced into smaller and smaller areas where there may not be enough food for the big cats to survive.
Tiger researchers estimate that there are no more than 5,000 tigers in the world. But there is a lot of work being done to make sure that tigers will survive.
In the early 1970s, India began passing laws against killing tigers. Since then, other countries with wild tigers have passed similar laws.
Many countries around the world, including the United States, have passed laws to stop the sale of products made from tiger parts.
International projects exist that help protect wild tiger habitat. Zoos help tigers through breeding programs and by teaching people around the world about these cats.

Dog
Pet Animal
Dog, (Canis lupus familiaris), domestic mammal of the family Canidae (order Carnivora). It is a subspecies of the gray wolf (Canis lupus) and is related to foxes and jackals.
The dog is one of the two most ubiquitous and most popular domestic animals in the world (the cat is the other). For more than 12,000 years it has lived with humans as a hunting companion, protector, object of scorn or adoration, and friend.
Millenia of puppy love have generated more than 400 breeds of domestic dog (Canis lupus familiaris), ranging from the wolfish, robust Siberian husky to the shrieking, guinea-pig adjacent chihuahua.
Research on the origin of dogs, and on their unique, sympatric relationships with humans, is ongoing. Now if someone would only figure out why LOLCats have such an edge over similar canine memes...
Dogs (Canis lupus familiaris) are domesticated mammals, not natural wild animals. They were originally bred from wolves. They have been bred by humans for a long time, and were the first animals ever to be domesticated.
There are different studies that suggest that this happened between 15.000 and 100.000 years before our time. The dingo is also a dog, but many dingos have become wild animals again and live independently of humans in the range where they occur
They are sometimes called "canines" from the Latin word for dog - canis. Sometimes people also use "dog" to describe other canids, such as wolves. A baby dog is called a pup or puppy. A dog is called a puppy until it is about one year old.
Dogs are sometimes referred to as "man's best friend" because they are kept as domestic pets and are usually loyal and like being around humans. Dogs like to be petted, but only when they can first see the petter's hand before petting; one should never pet a dog from behind.
General characteristics
Anatomy
Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes.
Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dogs are predators and scavengers; like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.
Size and weight
Dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier, that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head-and-body,
and weighed only 113 grams (4.0 oz). The largest known dog was a Saint Bernard which weighed 167.6 kg (369 lb) and was 250 cm (98 in) from the snout to the tail. The tallest dog is a Great Dane that stands 106.7 cm (42.0 in) at the shoulder.
Senses
The dog's senses include vision, hearing, sense of smell, sense of taste, touch and sensitivity to the earth's magnetic field. Another study suggested that dogs can see the earth's magnetic field.
Coat
The coats of domestic dogs are of two varieties: "double" being common with dogs (as well as wolves) originating from colder climates, made up of a coarse guard hair and a soft down hair, or "single", with the topcoat only. Breeds may have an occasional "blaze", stripe, or "star" of white fur on their chest or underside.
Regarding coat appearance or health, the coat can be maintained or affected by multiple nutrients present in the diet, see Coat (dog) for more information.
Premature graying can occur in dogs from as early as one year of age. This has been shown to be associated with impulsive behaviors, anxiety behaviors, fear of noise, and fear of unfamiliar people or animals.
Tail
There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state,
which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries.In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.
Health
Some breeds of dogs are prone to certain genetic ailments such as elbow and hip dysplasia, blindness, deafness, pulmonic stenosis, cleft palate, and trick knees. Two serious medical conditions particularly affecting dogs are pyometra, affecting unspayed females of all types and ages,
and gastric dilatation volvulus (bloat), which affects the larger breeds or deep-chested dogs. Both of these are acute conditions, and can kill rapidly. Dogs are also susceptible to parasites such as fleas, ticks, mites, hookworms, tapeworms, roundworms, and heartworms (roundworm species that lives in the heart of dogs).
A number of common human foods and household ingestibles are toxic to dogs, including chocolate solids (theobromine poisoning), onion and garlic (thiosulphate, sulfoxide or disulfide poisoning), grapes and raisins, macadamia nuts, xylitol, as well as various plants and other potentially ingested materials.
The nicotine in tobacco can also be dangerous. Dogs can be exposed to the substance by scavenging through garbage bins or ashtrays and eating cigars and cigarettes. Signs can be vomiting of large amounts (e.g., from eating cigar butts) or diarrhea.
Some other signs are abdominal pain, loss of coordination, collapse, or death. Dogs are susceptible to theobromine poisoning, typically from ingestion of chocolate.
Theobromine is toxic to dogs because, although the dog's metabolism is capable of breaking down the chemical, the process is so slow that for some dogs even small amounts of chocolate can be fatal, especially dark chocolate.
Lifespan
In 2013, a study found that mixed breeds live on average 1.2 years longer than pure breeds, and that increasing body-weight was negatively correlated with longevity (i.e. the heavier the dog the shorter its lifespan).
The typical lifespan of dogs varies widely among breeds, but for most the median longevity, the age at which half the dogs in a population have died and half are still alive, ranges from 10 to 13 years. Individual dogs may live well beyond the median of their breed.
The breed with the shortest lifespan (among breeds for which there is a questionnaire survey with a reasonable sample size) is the Dogue de Bordeaux, with a median longevity of about 5.2 years, but several breeds, including miniature bull terriers, bloodhounds, and Irish wolfhounds are nearly as short-lived, with median longevities of 6 to 7 years.
Teeth
Dogs have two sets of teeth. Twenty-eight deciduous teeth erupt by six to eight weeks of age, and by the time puppies are six to seven months old these deciduous teeth are all replaced by 42 adult teeth.
The permanent teeth include incisors, which are used to nip and bite; canines, which tear and shred flesh; and premolars and molars, which shear and crush. In short, a dog’s teeth serve as weapons and as tools for cutting or tearing food.
The canines are the upper and lower fangs for which the dog family was named. As in most carnivores, the teeth are high-crowned and pointed, unlike the broad, grinding teeth of many herbivorous animals.

Dogs are predators and scavengers; like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.
Size and weight
Dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier, that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head-and-body,
and weighed only 113 grams (4.0 oz). The largest known dog was a Saint Bernard which weighed 167.6 kg (369 lb) and was 250 cm (98 in) from the snout to the tail. The tallest dog is a Great Dane that stands 106.7 cm (42.0 in) at the shoulder.
Senses
The dog's senses include vision, hearing, sense of smell, sense of taste, touch and sensitivity to the earth's magnetic field. Another study suggested that dogs can see the earth's magnetic field.
Coat
The coats of domestic dogs are of two varieties: "double" being common with dogs (as well as wolves) originating from colder climates, made up of a coarse guard hair and a soft down hair, or "single", with the topcoat only. Breeds may have an occasional "blaze", stripe, or "star" of white fur on their chest or underside.
Regarding coat appearance or health, the coat can be maintained or affected by multiple nutrients present in the diet, see Coat (dog) for more information.
Premature graying can occur in dogs from as early as one year of age. This has been shown to be associated with impulsive behaviors, anxiety behaviors, fear of noise, and fear of unfamiliar people or animals.
Tail
There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state,
which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries.In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.
Health
Some breeds of dogs are prone to certain genetic ailments such as elbow and hip dysplasia, blindness, deafness, pulmonic stenosis, cleft palate, and trick knees. Two serious medical conditions particularly affecting dogs are pyometra, affecting unspayed females of all types and ages,
and gastric dilatation volvulus (bloat), which affects the larger breeds or deep-chested dogs. Both of these are acute conditions, and can kill rapidly. Dogs are also susceptible to parasites such as fleas, ticks, mites, hookworms, tapeworms, roundworms, and heartworms (roundworm species that lives in the heart of dogs).
A number of common human foods and household ingestibles are toxic to dogs, including chocolate solids (theobromine poisoning), onion and garlic (thiosulphate, sulfoxide or disulfide poisoning), grapes and raisins, macadamia nuts, xylitol, as well as various plants and other potentially ingested materials.
The nicotine in tobacco can also be dangerous. Dogs can be exposed to the substance by scavenging through garbage bins or ashtrays and eating cigars and cigarettes. Signs can be vomiting of large amounts (e.g., from eating cigar butts) or diarrhea.
Some other signs are abdominal pain, loss of coordination, collapse, or death. Dogs are susceptible to theobromine poisoning, typically from ingestion of chocolate.
Theobromine is toxic to dogs because, although the dog's metabolism is capable of breaking down the chemical, the process is so slow that for some dogs even small amounts of chocolate can be fatal, especially dark chocolate.
Lifespan
In 2013, a study found that mixed breeds live on average 1.2 years longer than pure breeds, and that increasing body-weight was negatively correlated with longevity (i.e. the heavier the dog the shorter its lifespan).
The typical lifespan of dogs varies widely among breeds, but for most the median longevity, the age at which half the dogs in a population have died and half are still alive, ranges from 10 to 13 years. Individual dogs may live well beyond the median of their breed.
The breed with the shortest lifespan (among breeds for which there is a questionnaire survey with a reasonable sample size) is the Dogue de Bordeaux, with a median longevity of about 5.2 years, but several breeds, including miniature bull terriers, bloodhounds, and Irish wolfhounds are nearly as short-lived, with median longevities of 6 to 7 years.
Teeth
Dogs have two sets of teeth. Twenty-eight deciduous teeth erupt by six to eight weeks of age, and by the time puppies are six to seven months old these deciduous teeth are all replaced by 42 adult teeth.
The permanent teeth include incisors, which are used to nip and bite; canines, which tear and shred flesh; and premolars and molars, which shear and crush. In short, a dog’s teeth serve as weapons and as tools for cutting or tearing food.
The canines are the upper and lower fangs for which the dog family was named. As in most carnivores, the teeth are high-crowned and pointed, unlike the broad, grinding teeth of many herbivorous animals.

Whale
Sea Animal
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates.
Phylum: Chordata
Order: Artiodactyla
Lifespan: Blue whale: 80 – 90 years, Killer whale: 29 years
Mass: Blue whale: 50,000 – 150,000 kg, MORE Encyclopedia of Life
Length: Blue whale: 25 m, Killer whale: 6 – 8 m, MORE Encyclopedia of Life
Gestation period: Blue whale: 10 – 12 months
Whale, any of the larger species of aquatic mammals belonging to the order Cetacea. The term whale can be used in reference to any cetacean, including porpoises and dolphins, but in general it is applied to those more than 3 metres (10 feet) long.
An exception is the 2.7-metre dwarf sperm whale (Kogia simus), so called for its otherwise striking resemblance to its larger namesake. Whales are the heaviest known animals, living or fossil, reaching a maximum size in the blue whale (Balaenoptera musculus) of perhaps more than 30 metres and 200 metric tons (220 short [U.S.] tons).
Whales are distributed throughout the world’s oceans and seas, from the Equator to the polar ice, except for the landlocked Caspian and Aral seas. They are mammals, and they share the defining traits of
that group: they breathe air, are warm-blooded, give live birth, suckle their young on milk, and have hair. All are entirely aquatic, with specialized adaptations such as flippers and tail flukes for living in water.
Whales must surface regularly to breathe, evacuating their lungs more completely than most mammals in an almost explosive breath known as a blow. Blows are visible because water vapour in the whale’s hot breath condenses when the blow is released.
Despite living in a medium that has much greater thermal conduction characteristics than air, whales, like other mammals, must regulate their body temperature.
Hair, however, is restricted to the head, appearing mainly as isolated whiskers (vibrissae) near the mouth and blowhole. Blubber serves as an insulating layer to protect small whales from hypothermia.
Large whales have the opposite problem in that they can produce too much heat; they possess elaborate thermoregulation mechanisms to prevent overheating.
Biology Of Whale
Etymology and definitions
The word "whale" comes from the Old English hwæl, from Proto-Germanic *hwalaz, from Proto Indo European *(s)kwal-o-, meaning "large sea fish".
The Proto-Germanic *hwalaz is also the source of Old Saxon hwal, Old Norse hvalr, hvalfiskr, Swedish val, Middle Dutch wal, walvisc, Dutch walvis, Old High German wal, and German Wal.
The obsolete "whalefish" has a similar derivation, indicating a time when whales were thought to be fish.[citation needed] Other archaic English forms include wal, wale, whal, whalle, whaille, wheal, etc.
The term "whale" is sometimes used interchangeably with dolphins and porpoises, acting as a synonym for Cetacea. Six species of dolphins have the word "whale" in their name, collectively known as blackfish: the killer whale, the melon
-headed whale, the pygmy killer whale, the false killer whale, and the two species of pilot whales, all of which are classified under the family Delphinidae (oceanic dolphins). Each species has a different reason for it, for example, the killer whale was named "Ballena asesina" 'killer whale' by Spanish sailors.
The term "Great Whales" covers those currently regulated by the International Whaling Commission: the Odontoceti family Physeteridae (sperm whales); and the Mysticeti families Balaenidae (right and bowhead whales), Eschrichtiidae (grey whales), and some of the Balaenopteridae (Minke, Bryde's, Sei, Blue and Fin; not Eden's and Omura's whales).
Mysticetes
Mysticetes are also known as baleen whales. They have a pair of blowholes side-by-side and lack teeth; instead they have baleen plates which form a sieve-like structure in the upper jaw made of keratin, which they use to filter plankton from the water. Some whales, such as the humpback, reside in the polar regions where they feed on a reliable source of schooling fish and krill.
These animals rely on their well-developed flippers and tail fin to propel themselves through the water; they swim by moving their fore-flippers and tail fin up and down. Whale ribs loosely articulate with their thoracic vertebrae
at the proximal end, but do not form a rigid rib cage. This adaptation allows the chest to compress during deep dives as the pressure increases.
Mysticetes consist of four families: rorquals (balaenopterids), cetotheriids, right whales (balaenids), and grey whales (eschrichtiids).
The main difference between each family of mysticete is in their feeding adaptations and subsequent behaviour. Balaenopterids are the rorquals. These animals, along with the cetotheriids, rely on their throat pleats to gulp large amounts of water while feeding.
The throat pleats extend from the mouth to the navel and allow the mouth to expand to a large volume for more efficient capture of the small animals they feed on. Balaenopterids consist of two genera and eight species.
Balaenids are the right whales. These animals have very large heads, which can make up as much as 40% of their body mass, and much of the head is the mouth.
This allows them to take in large amounts of water into their mouths, letting them feed more effectively. Eschrichtiids have one living member: the grey whale. They are bottom feeders, mainly eating crustaceans and benthic invertebrates.
They feed by turning on their sides and taking in water mixed with sediment, which is then expelled through the baleen, leaving their prey trapped inside. This is an efficient method of hunting, in which the whale has no major competitors.
Odontocetes
Odontocetes are known as toothed whales; they have teeth and only one blowhole. They rely on their well-developed sonar to find their way in the water. Toothed whales send out ultrasonic clicks using the melon. Sound waves travel through the water.
Upon striking an object in the water, the sound waves bounce back at the whale. These vibrations are received through fatty tissues in the jaw, which is then rerouted into the ear-bone and into the brain where the vibrations are interpreted.
All toothed whales are opportunistic, meaning they will eat anything they can fit in their throat because they are unable to chew. These animals rely on their well-developed flippers and tail fin to propel themselves through the water; they swim by moving their fore-flippers and tail fin up and down.
Whale ribs loosely articulate with their thoracic vertebrae at the proximal end, but they do not form a rigid rib cage. This adaptation allows the chest to compress during deep dives as opposed to resisting the force of water pressure.
Excluding dolphins and porpoises, odontocetes consist of four families: belugas and narwhals (monodontids), sperm whales (physeterids), dwarf and pygmy sperm whales (kogiids), and beaked whales (ziphiids).
There are six species, sometimes referred to as "blackfish", that are dolphins commonly misconceived as whales: the killer whale, the melon-headed whale, the pygmy killer whale, the false killer whale, and the two species of pilot whales, all of which are classified under the family Delphinidae (oceanic dolphins).
Evolution
Whales are descendants of land-dwelling mammals of the artiodactyl order (even-toed ungulates). They are related to the Indohyus, an extinct chevrotain-like ungulate, from which they split approximately 48 million years ago.
Primitive cetaceans, or archaeocetes, first took to the sea approximately 49 million years ago and became fully aquatic 5–10 million years later.
What defines an archaeocete is the presence of anatomical features exclusive to cetaceans, alongside other primitive features not found in modern cetaceans, such as visible legs or asymmetrical teeth.
Their features became adapted for living in the marine environment. Major anatomical changes included their hearing set-up that channeled vibrations from the jaw to the earbone (Ambulocetus 49 mya), a streamlined body and the growth
of flukes on the tail (Protocetus 43 mya), the migration of the nostrils toward the top of the cranium (blowholes), and the modification of the forelimbs into flippers (Basilosaurus 35 mya), and the shrinking and eventual disappearance of the hind limbs (the first odontocetes and mysticetes 34 mya).
Whale morphology shows a number of examples of convergent evolution, the most obvious being the streamlined fish-like body shape.
Other examples include the use of echolocation for hunting in low light conditions — which is the same hearing adaptation used by bats — and, in the rorqual whales, jaw adaptations, similar to those found in pelicans, that enable engulfment feeding.
Anatomy
Whales have torpedo shaped bodies with non-flexible necks, limbs modified into flippers, non-existent external ear flaps, a large tail fin, and flat heads (with the exception of monodontids and ziphiids).
Whale skulls have small eye orbits, long snouts (with the exception of monodontids and ziphiids) and eyes placed on the sides of its head. Whales range in size from the 2.6-metre (8.5 ft) and 135-kilogram (298 lb) dwarf sperm whale to the 34-metre (112 ft) and 190-metric-ton (210-short-ton) blue whale.
Overall, they tend to dwarf other cetartiodactyls; the blue whale is the largest creature on earth. Several species have female-biased sexual dimorphism, with the females being larger than the males. One exception is with the sperm whale, which has males larger than the females.
Odontocetes, such as the sperm whale, possess teeth with cementum cells overlying dentine cells. Unlike human teeth, which are composed mostly of enamel on the portion of the tooth outside of the gum, whale teeth have cementum outside the gum.
Only in larger whales, where the cementum is worn away on the tip of the tooth, does enamel show. Mysticetes have large whalebone, as opposed to teeth, made of keratin. Mysticetes have two blowholes, whereas Odontocetes contain only one.
Locomotion
Whales have two flippers on the front, and a tail fin. These flippers contain four digits. Although whales do not possess fully developed hind limbs, some, such as the sperm whale and bowhead whale, possess discrete rudimentary appendages, which may contain feet and digits.
Whales are fast swimmers in comparison to seals, which typically cruise at 5–15 kn, or 9–28 kilometres per hour (5.6–17.4 mph); the fin whale, in comparison, can travel at speeds up to 47 kilometres per hour (29 mph) and the sperm whale can reach speeds of 35 kilometres per hour (22 mph).
The fusing of the neck vertebrae, while increasing stability when swimming at high speeds, decreases flexibility; whales are unable to turn their heads. When swimming, whales rely on their tail fin propel them through the water.
Flipper movement is continuous. Whales swim by moving their tail fin and lower body up and down, propelling themselves through vertical movement, while their flippers are mainly used for steering.
Some species log out of the water, which may allow them to travel faster. Their skeletal anatomy allows them to be fast swimmers. Most species have a dorsal fin.
Senses
The whale ear has specific adaptations to the marine environment. In humans, the middle ear works as an impedance equalizer between the outside air's low impedance and the cochlear fluid's high impedance.
In whales, and other marine mammals, there is no great difference between the outer and inner environments. Instead of sound passing through the outer ear to the middle ear, whales receive sound through the throat, from which it passes through a low-impedance fat-filled cavity to the inner ear.
The whale ear is acoustically isolated from the skull by air-filled sinus pockets, which allow for greater directional hearing underwater.
Odontocetes send out high frequency clicks from an organ known as a melon. This melon consists of fat, and the skull of any such creature containing a melon will have a large depression.
The melon size varies between species, the bigger the more dependent they are of it. A beaked whale for example has a small bulge sitting on top of its skull, whereas a sperm whale's head is filled up mainly with the melon.
Communications
Whale vocalization is likely to serve several purposes. Some species, such as the humpback whale, communicate using melodic sounds, known as whale song.
These sounds may be extremely loud, depending on the species. Humpback whales only have been heard making clicks, while toothed whales use sonar that may generate up to 20,000 watts of sound (+73 dBm or +43 dBw)[58] and be heard for many miles.
Captive whales have occasionally been known to mimic human speech. Scientists have suggested this indicates a strong desire on behalf of the whales to communicate with humans, as whales have a very different vocal mechanism, so imitating human speech likely takes considerable effort.
Whales emit two distinct kinds of acoustic signals, which are called whistles and clicks: Clicks are quick broadband burst pulses, used for sonar, although some lower-frequency broadband vocalizations may serve a non-echolocative purpose such as communication; for example, the pulsed calls of belugas.
Pulses in a click train are emitted at intervals of ≈35–50 milliseconds, and in general these inter-click intervals are slightly greater than the round-trip time of sound to the target. Whistles are narrow-band frequency modulated (FM) signals, used for communicative purposes, such as contact calls.
Life cycle
Whales are fully aquatic creatures, which means that birth and courtship behaviours are very different from terrestrial and semi-aquatic creatures. Since they are unable to go onto land to calve, they deliver the baby with the fetus positioned for tail-first delivery.
This prevents the baby from drowning either upon or during delivery. To feed the new-born, whales, being aquatic, must squirt the milk into the mouth of the calf. Being mammals, they have mammary glands used for nursing calves; they are weaned off at about 11 months of age.
This milk contains high amounts of fat which is meant to hasten the development of blubber; it contains so much fat that it has the consistency of toothpaste.
Females deliver a single calf with gestation lasting about a year, dependency until one to two years, and maturity around seven to ten years, all varying between the species.
This mode of reproduction produces few offspring, but increases the survival probability of each one. Females, referred to as "cows", carry the responsibility of childcare as males, referred to as "bulls", play no part in raising calves.

Welcome my fk animal channel
Cat, (Felis catus), also called house cat or domestic cat, domesticated member of the family Felidae, order Carnivora, and the smallest member of that family.
Like all felids, domestic cats are characterized by supple low-slung bodies, finely molded heads, long tails that aid in balance, and specialized teeth and claws that adapt them admirably to a life of active hunting.
Cats possess other features of their wild relatives in being basically carnivorous, remarkably agile and powerful, and finely coordinated in movement.
It is noteworthy that the ancestors of the other common household pet, the dog, were social animals that lived together in packs in which there was subordination to a leader, and the dog has readily transferred its allegiance from pack leader to human master.
The cat, however, has not yielded as readily to subjugation. Consequently, the house cat is able to revert to complete self-reliance more quickly and more successfully than most domesticated dogs. For an account of the relationship of the family of cats to other carnivores, see carnivore.
General characteristics
Coordination and musculature
Cats are among the most highly specialized of the flesh-eating mammals. Their brains are large and well developed. Cats are digitigrade; that is, they walk on their toes.
Unlike the dog and horse, the cat walks or runs by moving first the front and back legs on one side, then the front and back legs on the other side; only the camel and the giraffe move in a similar way. The cat’s body has great elasticity.
Because the vertebrae of the spinal column are held together by muscles rather than by ligaments, as in humans, the cat can elongate or contract its back, curve it upward, or oscillate it along the vertebral line.
The construction of the shoulder joints permits the cat to turn its foreleg in almost any direction. Cats are powerfully built animals and are so well coordinated that they almost invariably land on their feet if they fall or are dropped.
Teeth
The cat’s teeth are adapted to three functions: stabbing (canines), anchoring (canines), and cutting (molars). Cats have no flat-crowned crushing teeth and therefore cannot chew their food; instead, they cut it up.
Except for the canines and molars, the cat’s teeth are more or less nonfunctional; most of the cheek teeth do not even meet when the mouth is closed.
The dental formula in all cats, for either side of both upper and lower jaws, is incisors 3/3, canines 1/1, premolars 3/2, and molars 1/1. The total number of teeth is 16 in the upper jaw and 14 in the lower.
Primary, or milk, teeth number 24; these are replaced by the permanent teeth at about five months. Each half of the jaw is hinged to the skull by a transverse roller that fits tightly into a trough on the underside of the skull, making grinding movements impossible even if the cat had teeth suitable for grinding.
Claws
There is a remarkable mechanism for retracting the cat’s claws when they are not in use. The claw is retracted or extended by pivoting the end bone of the toe, which bears the claw, over the tip of the next bone.
The action that unsheathes the claws also spreads the toes widely, making the foot more than twice as broad as it normally is and converting it into a truly formidable weapon.
This claw-sheathing mechanism is present in all species of the cat family except the cheetah. Although there are no nerve endings in the nail itself, blood capillaries are present in the inner part.
Senses
Cats are generally nocturnal in habit. The retina of the cat’s eye is made extra sensitive to light by a layer of guanine, which causes the eye to shine at night in a strong light.
The eyes themselves, large with pupils that expand or contract to mere slits according to the density of light, do not distinguish colours clearly. Cats have a third eyelid, or nictitating membrane, commonly called the haw. Its appearance is used frequently as an indicator of the cat’s general state of health.
The cat’s sense of smell, particularly well developed in the adult, is crucial to its evaluation of food, so that a cat whose nasal passages become clogged as a result of illness may appear to lose its appetite completely. Cats can distinguish the odour of nitrogenous substances (e.g., fish) especially keenly.
The sense of touch is acute in cats. The eyebrows, whiskers, hairs of the cheek, and fine tufts of hair on the ears are all extremely sensitive to vibratory stimulation.
The functions of the whiskers (vibrissae) are only partially understood; however, it is known that, if they are cut off, the cat is temporarily incapacitated. The toes and paws, as well as the tip of the nose, are also very sensitive to touch.
Cats also have an acute sense of hearing. Their ears contain almost 30 muscles (compared with 6 in humans); as a result, they can turn them many times more quickly in the direction of a sound than can a dog.
The ears of cats are receptive to ultrasonic frequencies up to 85,000 vibrations per second, greatly exceeding the hearing capabilities of dogs, which register 35,000 vibrations per second.

Dog
Pet Animal
Dog, (Canis lupus familiaris), domestic mammal of the family Canidae (order Carnivora). It is a subspecies of the gray wolf (Canis lupus) and is related to foxes and jackals.
The dog is one of the two most ubiquitous and most popular domestic animals in the world (the cat is the other). For more than 12,000 years it has lived with humans as a hunting companion, protector, object of scorn or adoration, and friend.
Millenia of puppy love have generated more than 400 breeds of domestic dog (Canis lupus familiaris), ranging from the wolfish, robust Siberian husky to the shrieking, guinea-pig adjacent chihuahua.
Research on the origin of dogs, and on their unique, sympatric relationships with humans, is ongoing. Now if someone would only figure out why LOLCats have such an edge over similar canine memes...
Dogs (Canis lupus familiaris) are domesticated mammals, not natural wild animals. They were originally bred from wolves. They have been bred by humans for a long time, and were the first animals ever to be domesticated.
There are different studies that suggest that this happened between 15.000 and 100.000 years before our time. The dingo is also a dog, but many dingos have become wild animals again and live independently of humans in the range where they occur
They are sometimes called "canines" from the Latin word for dog - canis. Sometimes people also use "dog" to describe other canids, such as wolves. A baby dog is called a pup or puppy. A dog is called a puppy until it is about one year old.
Dogs are sometimes referred to as "man's best friend" because they are kept as domestic pets and are usually loyal and like being around humans. Dogs like to be petted, but only when they can first see the petter's hand before petting; one should never pet a dog from behind.
General characteristics
Anatomy
Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes.
Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dogs are predators and scavengers; like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.

Hamster
Pet Animal
Description Hamsters are rodents belonging to the subfamily Cricetinae, which contains 18 species classified in seven genera. They have become established as popular small house pets.
The best-known species of hamster is the golden or Syrian hamster, which is the type most commonly kept as pets.
Gestation period: Roborovski dwarf hamster: 22 days
Class: Mammalia
Lifespan: Roborovski dwarf hamster: 3 years, Chinese hamster: 2 – 3 years
Mass: Roborovski dwarf hamster: 20 – 25 g
Chinese hamster: 30 – 45 g
Chinese striped hamster: 17 – 31 g
If you are thinking about getting a pet hamster for you or a child it is important that you know how to choose one, what supplies you need, and how to feed and care for your new pet.
Hamsters are typically low-maintenance pets but proper care is essential to keeping it happy and healthy.
7 Things to Know About Hamsters
Experience Level: Beginner
Size: Dwarf hamsters grow up to 3 to 4 inches (8-10 cm) long. Syrians grow up to 7 inches (18 cm) long
Lifespan: Hamsters live for approximately 2 years
Sleep Patterns: Hamsters are nocturnal and mostly active at night
Diet: As omnivores, hamsters feed on plants and greens
On the Move: Hamsters have fur-lined pouches that extend from their head to their shoulders used to transport food
Choose a Healthy Hamster
Not every hamster in the pet store is in optimal health. Moving from a breeder or supplier to a store can be a stressful period for baby hamsters, and they will often get sick from it.
Choose an active hamster and one that doesn't look like it has a wet rear end or watery eyes. Both eyes should be open and ideally the hamster will be eating or running around the cage.
If a cage seems to have a few sick hamsters, it is probably best to avoid buying any hamster from that group since hamster diseases are very contagious.
Choosing a hamster that is easy to tame is another factor to consider. Young hamsters will be easier to train and hand tame than older hamsters who may have had bad experiences or have never had human interaction.
Feeding Hamsters
Most people assume that a store-bought bag of hamster seed is what is best for a hamster but they actually need a variety of proteins, fruits, and vegetables to keep them healthy and happy.
Hamsters may pick and choose what they want to eat from seed mixtures and therefore will not receive a balanced diet. But if you offer a pelleted diet instead of a seed mixture and supplement it with a variety of other safe foods, you will be providing your hamster with everything it needs to thrive.

Pet Animal
Dog, (Canis lupus familiaris), domestic mammal of the family Canidae (order Carnivora). It is a subspecies of the gray wolf (Canis lupus) and is related to foxes and jackals.
The dog is one of the two most ubiquitous and most popular domestic animals in the world (the cat is the other). For more than 12,000 years it has lived with humans as a hunting companion, protector, object of scorn or adoration, and friend.
Millenia of puppy love have generated more than 400 breeds of domestic dog (Canis lupus familiaris), ranging from the wolfish, robust Siberian husky to the shrieking, guinea-pig adjacent chihuahua.
Research on the origin of dogs, and on their unique, sympatric relationships with humans, is ongoing. Now if someone would only figure out why LOLCats have such an edge over similar canine memes...
Dogs (Canis lupus familiaris) are domesticated mammals, not natural wild animals. They were originally bred from wolves. They have been bred by humans for a long time, and were the first animals ever to be domesticated.
There are different studies that suggest that this happened between 15.000 and 100.000 years before our time. The dingo is also a dog, but many dingos have become wild animals again and live independently of humans in the range where they occur
They are sometimes called "canines" from the Latin word for dog - canis. Sometimes people also use "dog" to describe other canids, such as wolves. A baby dog is called a pup or puppy. A dog is called a puppy until it is about one year old.
Dogs are sometimes referred to as "man's best friend" because they are kept as domestic pets and are usually loyal and like being around humans. Dogs like to be petted, but only when they can first see the petter's hand before petting; one should never pet a dog from behind.
General characteristics
Anatomy
Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes.
Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dogs are predators and scavengers; like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.
Size and weight
Dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier, that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head-and-body,
and weighed only 113 grams (4.0 oz). The largest known dog was a Saint Bernard which weighed 167.6 kg (369 lb) and was 250 cm (98 in) from the snout to the tail. The tallest dog is a Great Dane that stands 106.7 cm (42.0 in) at the shoulder.
Senses
The dog's senses include vision, hearing, sense of smell, sense of taste, touch and sensitivity to the earth's magnetic field. Another study suggested that dogs can see the earth's magnetic field.
Coat
The coats of domestic dogs are of two varieties: "double" being common with dogs (as well as wolves) originating from colder climates, made up of a coarse guard hair and a soft down hair, or "single", with the topcoat only. Breeds may have an occasional "blaze", stripe, or "star" of white fur on their chest or underside.
Regarding coat appearance or health, the coat can be maintained or affected by multiple nutrients present in the diet, see Coat (dog) for more information.
Premature graying can occur in dogs from as early as one year of age. This has been shown to be associated with impulsive behaviors, anxiety behaviors, fear of noise, and fear of unfamiliar people or animals.
Tail
There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state,
which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries.In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.
Health
Some breeds of dogs are prone to certain genetic ailments such as elbow and hip dysplasia, blindness, deafness, pulmonic stenosis, cleft palate, and trick knees. Two serious medical conditions particularly affecting dogs are pyometra, affecting unspayed females of all types and ages,
and gastric dilatation volvulus (bloat), which affects the larger breeds or deep-chested dogs. Both of these are acute conditions, and can kill rapidly. Dogs are also susceptible to parasites such as fleas, ticks, mites, hookworms, tapeworms, roundworms, and heartworms (roundworm species that lives in the heart of dogs).
A number of common human foods and household ingestibles are toxic to dogs, including chocolate solids (theobromine poisoning), onion and garlic (thiosulphate, sulfoxide or disulfide poisoning), grapes and raisins, macadamia nuts, xylitol, as well as various plants and other potentially ingested materials.
The nicotine in tobacco can also be dangerous. Dogs can be exposed to the substance by scavenging through garbage bins or ashtrays and eating cigars and cigarettes. Signs can be vomiting of large amounts (e.g., from eating cigar butts) or diarrhea.
Some other signs are abdominal pain, loss of coordination, collapse, or death. Dogs are susceptible to theobromine poisoning, typically from ingestion of chocolate.
Theobromine is toxic to dogs because, although the dog's metabolism is capable of breaking down the chemical, the process is so slow that for some dogs even small amounts of chocolate can be fatal, especially dark chocolate.
Lifespan
In 2013, a study found that mixed breeds live on average 1.2 years longer than pure breeds, and that increasing body-weight was negatively correlated with longevity (i.e. the heavier the dog the shorter its lifespan).
The typical lifespan of dogs varies widely among breeds, but for most the median longevity, the age at which half the dogs in a population have died and half are still alive, ranges from 10 to 13 years. Individual dogs may live well beyond the median of their breed.
The breed with the shortest lifespan (among breeds for which there is a questionnaire survey with a reasonable sample size) is the Dogue de Bordeaux, with a median longevity of about 5.2 years, but several breeds, including miniature bull terriers, bloodhounds, and Irish wolfhounds are nearly as short-lived, with median longevities of 6 to 7 years.
Teeth
Dogs have two sets of teeth. Twenty-eight deciduous teeth erupt by six to eight weeks of age, and by the time puppies are six to seven months old these deciduous teeth are all replaced by 42 adult teeth.
The permanent teeth include incisors, which are used to nip and bite; canines, which tear and shred flesh; and premolars and molars, which shear and crush. In short, a dog’s teeth serve as weapons and as tools for cutting or tearing food.
The canines are the upper and lower fangs for which the dog family was named. As in most carnivores, the teeth are high-crowned and pointed, unlike the broad, grinding teeth of many herbivorous animals.
