Dogs

The dog is a  carnivorous mammal of the Canidae family, from the wolf,  Canis lupus. Familiaris because it was domesticated by humans more than 30,000 years ago. He was selected through hybridization between breeds.

And the dog is today – with the cat – one of the favorite pets in the world. There are more than 300 breeds.

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.
