The dog is a mammal in the canine family of the Order Carnivora.

Dogs were first domesticated from wolves at least 15,000 years ago.

Dogs, like humans, are highly social animals and this similarity in their overall behavioral pattern accounts for their trainability, playfulness, and ability to fit into human households and social situations.
