What is a domestic dog? The term ādomestic dogā refers to any of several
hundred breeds of dog in the world today. While these animals vary
drastically in appearance, every dogāfrom the Chihuahua to the Great
Daneāis a member of the same species, Canis familiaris. This separates
domestic dogs from wild canines, such as coyotes, foxes, and wolves.

surviving on their own, whether itās in a forest or on city streets. A
third of all households worldwide have a dog, according to a 2016
consumer insights study. This makes the domestic dog the most popular
pet on the planet.
