The Gray Wolf (Canis lupus; other forms: Timber Wolf, Wolf; British English: Grey Wolf) is a mammal of the Canidae family. The wolf shares a common ancestry with the domestic dog (Canis familiaris), and, according to most experts, is likely the progenitor of all dogs as they exist today (in which case, the domestic dog would more accurately be classified as Canis lupus familiaris).
