The American Bulldogs Have two type breeds.

The very muscular, sturdy and powerful, yet compact frame of the American Bulldog remains higher on the leg, more agile and swifter than its English counterpart. Some individuals are reportedly able to leap six or more feet into the air. Males are characteristically stockier and heavier boned than in the more refined females. The head is large with strong jaws. Agile and light on his feet. The chest is wide and moderately deep giving the sense of athletic ability and power. The neck is muscular tapering from the shoulders to the head and may have a slight dewlap. The head is square, large and broad with muscular cheeks relatively in proportion to the size and overall structure of the dog. There is a defined furrow between the rounded eyes, with a distinct, sharply defined , deep stop. The strong muzzle is broad and square. The preferred bite is reverse scissors, but a moderate underbite, scissors or even bite is acceptable.
