The dog is a carnivorous mammal of the canid family, from the wolf, Canis lupus. Its scientific name is besides Canis lupus familiaris. Familiaris because it was domesticated by humans more than 30,000 years ago. It has been selected through cross-breed hybridizations. And the dog is today – with the cat – one of the favorite pets in the world. There are more than 300 breeds.

If chihuahua – the smallest dog in the world – at the Irish wolfhound – the largest dog in the world – these breeds have sometimes very different external morphologies – of a variety without any other equal in the animal kingdom – their internal anatomy remains similar. Thus the skeleton of the dog has some 300 bones. And it should be noted that his legs rest on the ground only by their third phalanx. Thus dogs are called digitigrades.

It should also be noted that the life expectancy of dogs varies depending on the breed in particular. Smaller dogs usually live older – between 15 and 20 years – than older ones – only 6 to 8 years old.

Rather sharp senses :

On the sense side, the sense of smell and hearing are the two most developed in dogs. Indeed, dogs are able to hear both ultrasound and infrasound that escape our human ear. And proportionally to their bodies, their ears are bigger than ours. With a form to amplify sounds too. Not to mention that they are also much more mobile than our ears. Dogs also have about 10 times more olfactory cells than humans and forty times more neurons dedicated to smell. Thus, they are able to discern more than 500,000 odorous molecules. On the other hand, we can say that the dog does not see the world as well as us. His vision is not able to distinguish the details, but he perceives the movements very well.

Hunting dog, watchdog and sheepdog

All these features make the dog a very popular pet. But it is also used by humans in other missions. He can be a sheepdog to monitor flocks or hunting dogs in the service of hunters. It can help rescue people in distress or act as a watchdog.
