Teeth
WOLVES: Wolves will have longer and thicker canine teeth than most dogs, as well as larger and more developed molars. The canine teeth should be very large and curve slightly, coming together in an even scissor bite. Underbites and overbites can occur, though it is usually due to severe inbreeding.
DOGS: All large canines should have 42 teeth, though some smaller or brachycephalic dog breeds such as English bulldogs may have fewer teeth due to crowding and jaw structure. Some northern breed dogs will have smaller teeth, while German shepherds often have teeth of similar size to wolves, usually being just slightly smaller. While Siberian huskies, Alaskan malamutes and German shepherds should have even scissor bites, underbites or overbites can occur.
