I think sometimes you might be suprised to find Bull in dogs that have no bully features at all. I think people consider the bull simply because of deep gameness. There is also less need for baying dogs with all the technology. A dog that is usually quicker to fight than most bulls is the Lakeland,and there aint many Russels free of that blood despite some of the famous breeders denying it till blue in the face. nope I'm not surprised at all lol
