Depends on the type of wolf we are talking about. Like timber wolves are the largest of the wolves, and they can be huge, I actually work with a wolf rescue and we have a timber wolf that is about average size and he is 120lbs, and about the size of a tall mastiff, or short great dane. When he stands on his hind legs he is over 6'3''. Then you have your much smaller wolves like the Mexican grey wolf and they are quite small comparatively. This is Hokshila the timber wolf.
This is Bindi, the Mexican grey wolf.
