• It seems the different lines of apbt are almost like different breeds. In australia most apbts are sorrels line, and I can assure you they are the worst guard dog you can imagine, and also really good with children with no dominance issues whatsoever. Almost to a fault like they are socially retarded, don't even understand when another dog is trying to be dominant or whatever, they're blind to all things pertaining to social heirarchy (except for their submissiveness towards humans). Even when they fight it has nothing to do with dominance, but rather it's a predatory-based game.
