Any dog. They will be a direct reflection of how you treat them. Some of the biggest babies I ever encountered are Rottweilers, Pit Bulls, Mastiffs, German Shepard. ANY breed you get, if you treat them like shit, they will act like shit, and you run a higher chance that they will bite/attack you, or give you problems. If you raise them good, and treat them right, ANY dog will be a fantastic member of your family.
