Doberman Pinschers
Doberman Pinschers are large dogs with little heads and strong jaws. They are incredibly loyal to their owners, but they are very dangerous to strangers and other dogs they don’t know. In fact, Pinschers used to be used as police dogs, but that practice was phased out because of how aggressive they were to strangers. They are considered to be the best dogs for guarding, as they will attack when intruders come in, or they sense their family is in danger.
