Dogs (Canis), forming part of the wolf’s evolution,[6] are also the most numerous terrestrial carnivores.[7][8][9][10][11] Dogs and gray wolves are sisters,[12][13][14] being, like modern wolves, not closely related to the first domesticated wolves,[13][14] synonymous with The original ancestors of dogs became extinct.

Dogs were also the first animals to be domesticated by humans[14][15] and have been bred over millennia for a variety of behaviors, senses, and physical characteristics.[16] This animal is used for house keeping or as a hobby. Their teeth are used to kill prey, chew meat and gnaw meat, sometimes to bite each other. Dogs are widely raised animals in the world, they can look after the house, herd sheep, guide the way, pull the cart, and are also a protein-rich food. Dogs help people with many things such as housekeeping, hunting, and are considered the most loyal and affectionate animals to humans. Today, the demand for pet dogs is growing, so small breeds like Fox, Chihuahua or intelligent dogs like Collie are interested by many players.

The ancestor of dogs, including foxes and wolves, was a weasel-like mammal that inhabited tree hollows about 40 million years ago. And the dog as we see it today evolved from a small, gray dog. At the end of the Ice Age, about 40,000 years ago, wolves and humans lived together in groups that hunted in packs. Wolves and humans often compete for prey, even killing each other. But the wolf must have begun to scavenge for the scraps of food left behind by humans. Humans domesticated wolf pups and through crossbreeding for generations, wolves evolved into today’s domestic dogs.
Classify
A hybrid dog
In 1758, taxonomist Carl Linnaeus published in his Systema Naturae the taxonomy of species, in which Canis (canine genus) is a Latin word for dog.[17] He classifies the domestic dog as Canis familiaris (Linnaeus, 1758) and on the next page on a separate species he classifies the wolf as Canis lupus (Linnaeus, 1758).[2] In 1926, the International Commission on Zoological Nomenclature (ICZN) made its thesis 91 that the domestic dog Canis familiaris (Linnaeus, 1758) was included in the official list.[3] In 1957, the ICZN specified in thesis 451 that ”Canis dingo (Meyer, 1793) was the name used for the dingo and was included in the official list of the species.[18] Dogs are also bred by humans to create many different dog breeds, very diverse. A hybrid dog breed is a dog breed that is grafted by two different parent dogs (color, shape, …). These two parents, after mating, will create a new breed of dog that has the attributes of its parents and ancestors.
Senses like sight, hearing and smell are well developed: Dogs have large eyes, erect ears and a sensitive nose, so they can successfully track down their prey, whether hunting alone or in groups. All dogs except the South American bush dog have long legs adapted to running fast when hunting. Dogs are “toe-walkers” and have characteristic paws, five toes on their front paws and four toes on their hind legs. Sometimes domestic dogs have five toes on their hind legs (the fifth nail is called the hypotenuse). Jackals have long tails, thick fur, usually uniform color and no striped spots.
The average gestation period for dogs lasts about 60 to 62 days, which can be earlier or as long as 65 days. At birth, puppies have no teeth, but after only 4 weeks of age, they can have 28 teeth. Like all mammals, after the young are born, the mother breastfeeds and cares for the young for a few months, with the help of other family members, at which point the mother will become an adult. should be ferocious. The full set of jaws of this animal is 42 pieces.
