Sexually mature at 10 months old.

Sometimes called lobo (Spanish for wolf).
More of these wolves in captivity than in wild-believed to be approximately 240 in captivity (all in U.S., Canada, & Mexico) & 160 in the wild.
Juveniles leave pack at 2-3 years old though some stay around for long.
Breed from mid-February to mid-March.
