Dog

The domestic dog (Canis familiaris) is a domestic canine and is the descendant of the gray wolf. They are the first species to be domesticated, by hunter-gathers over 15,000 years ago. Their long association with humans later made dogs adapted to human behavior. Dogs have been selctively bred over millennia for various behaviors, sensory capabilities, and physical attributes. They, along with cats, are the most widespread carnivorans.
