Mexican Gray Wolf (Canis lupus baileyi) is the largest member of the dog family in New Mexico (up to 1.6 m). Historically they were widely distributed through Arizona, New Mexico, and Texas, south into central Mexico. They have been extirpated from most of their historic range and in recent years have been reintroduced to New Mexico and Arizona. They can inhabit any habitat type where their presence doesn’t conflict with human land uses and where prey, including large ungulates, is abundant.
