Do werewolves have any related species?

Dogs are generally considered by modern biologists to be the same species as wolves, though older works may refer to them as different (albeit clearly closely related) species.

Other species in the genus Canis include coyotes and jackals. Some animals called wolves are not subspecies of Canis lupus, and thus technically not "wolves", though many of them are closely related. An example of one that is NOT is the Tasmanian wolf (thought to have become extinct in the 20th century), which was actually more closely related to kangaroos than to wolves.
