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 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 are acceptable. A variety of ear types are acceptable including cropped, rose, half-pricked and forward flap. Uncropped ears are preferred in the American Bulldog Breeders Association standard. Eyes are most often brown, but can come in any color. They sometimes have split eyes, where one eye is brown and the other eye is blue. Black eye rims are preferred on white dogs. Pink eye rims are considered a fault according to the written standard. The nose is black, red, brown or grizzle; black is the preferred color according to the standard. In black-nosed dogs, the preferred lip color is black, though some pink is permitted. The lips should be full but not too loose. The front legs are heavy-boned, strong and straight. The hindquarters should be very broad and thick with well-defined muscles. The tail is low-set, begins thick at the base, and tapers to a point. The coat is smooth and short, and comes in all shades of brindle including red brindle, varying degrees of white, red, brown, tan, fawn and piebald.


The American Bulldog is loyal, reliable, brave and determined. Not a hostile dog. Alert and self-confident, this breed genuinely loves children. It is known for its acts of heroism toward its master. It has strong protective instincts, and needs a firm, confident, consistent pack leader. Well-socialize and obedience train them at an early age, to prevent them from becoming reserved with strangers. Without that strong-minded pack leader who can tell the dog what is expected of it, it may be aggressive with other dogs. They need to be around people and know their place in their pack to be truly happy. This breed tends to drool and slobber. Without enough daily mental and physical exercise they will become high strung and may become hard to handle.

The original American Bulldogs were not only used in the bloody sport of bull bating, but also by small farmers and ranchers who used them as all-around working dogs for many tasks including as guards and for hunting bear, wild boar, raccoon and squirrel. The American version of the Bulldog has longer legs, is faster and has better agility than the English show dog. The dog’s stamina, protectiveness, intelligence and working abilities make him a prized worker for farmers. They can be trained to drive cattle and guard stock from predators. Thanks to the efforts of John D. Johnson of Summerville, Georgia, the American Bulldog exists today. After Johnson returned from WWII he was disappointed to find that, like the English Mastiff, it was almost completely extinct. He then decided to gather the best specimens he could find from all across the rural South in an effort to bring the American Bulldog back from the brink of extinction. He has been breeding these dogs longer than anyone else in the world and his father bred them before him. He is an old man now and these dogs have always existed in his family. He is the sole reason why they exist today. If it were not for his efforts they surely would be extinct. He has been breeding them nonstop since then. Some of the American Bulldog’s talents are hunting, watchdog, tracking, weight pulling and guarding.
