DOG

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

Dogs have lived and worked with humans in so many roles that they have earned the unique nickname, “man’s best friend”, a phrase used in other languages as well. They have been bred for herding livestock  hunting (e.g. pointers and hounds), rodent control,guarding, helping fishermen with nets, detection dogs, and pulling loads, in addition to their roles as companions.
