Most of the good dogs I've had, have been teeth on legs as pups, with no respect for anyone or anything, and yet loyal and biddable in a lot of ways. If that makes sense. They also when watching them play fight and hunt the rest of the pack as little pups, they display a lot of natural skills, funny stuff like the way they move their legs not to get bitten, always have a back of getting the throat and dont give a hoot about being bitten back.
