The First Canids: Hesperocyon and the "Bone-Crushing Dogs" Paleontologists agree that the late Eocene (about 40 to 35 million years ago) Hesperocyon was directly ancestral to all later canids and thus to the genus Canis, which branched off from a subfamily of canids about six million years ago. They also retain adult offspring in the social group, suppressing the ability of these to breed while making use of the alloparental care they can provide to help raise the next generation of offspring. The domestic dog ( C. lupus familiaris) has been domesticated for thousand of years and has been useful to humans in many ways, such as transport, guarding of livestock, and protection, although many are used primarily for companionship.

Like most other members of the Carnivora order, canids are adapted for a life of hunting and eating other animals. Canids prey on a wide range of animals. It's including 35 extanct species.

The family includes three subfamilies: the extant Caninae and the extinct Borophaginae and Hesperocyoninae. lepophagus. These sounds are frequently associated with specialized visual signals involving movements of the ears and tail, raising of certain areas of fur, and baring of teeth. reproduction that includes combining the genetic contribution of two individuals, a male and a female. Hairs grow between the pads and in the Arctic fox the sole of the foot is densely covered with hair at some times of the year. Within a canid pack there is a system of dominance so that the strongest, most experienced animals lead the pack.
