Wolves are large, predatory canids once common throughout North America, Europe, Africa and Asia, now living mostly in remote wilderness. They are the largest living members of the canid family, which also includes foxes and coyotes.Wolves are the ancestors of all domestic dogs.There are two species of wolves in North America. The smaller species is the red wolf, Canis rufus, which has shorter, redder fur than the gray wolf. The gray wolf, Canis lupus, has thicker fur which is more gray or golden, and is larger than the red wolf.olves are large, predatory canids once common throughout North America, Europe, Africa and Asia, now living mostly in remote wilderness.

The origin of the domestic dog is not clear. The domestic dog is a member of genus Canis (canines) that forms part of the wolf-like canids, and is the most widely abundant carnivore. The closest living relative of the dog is the gray wolf and there is no evidence of any other canine contributing to its genetic lineage. The dog and the extant gray wolf form two sister clades, with modern wolves not closely related to the wolves that were first domesticated.
