Dog

The domestic dog (Canis lupus familiaris) is a subspecies of the gray wolf (Canis lupus), a member of the Canidae family of the mammalian order Carnivora. The term “domestic dog” is generally used for both domesticated and feral varieties. The dog has been the first animal to be domesticated and has been the most widely kept working, hunting, and pet animal in human history. The word “dog” may also mean the male of a canine species, as opposed to the word “bitch” for the female of the species.
