Size and Build
American Bullies present a compact, muscular physique with males and females standing between 33 to 53 cm at the withers. Their weight varies significantly depending on the type, with some individuals weighing 31 kg and others exceeding 120 kg, reflecting the breed's broad size range. The body is well proportioned, stocky, and powerfully muscled, projecting agility and strength without appearing clumsy.
Coat and Colours
The coat is short, smooth, and glossy, lying close to the skin with a slightly stiff texture. All coat colours are accepted except for merle, which is disallowed under breed standards. Colour patterns can range widely, reflecting the diverse breeding heritage. Seasonal shedding is minimal but regular grooming helps maintain optimal coat condition.
Distinctive Features
The American Bully’s head is notably broad and large but balanced with the body. The head has a well-defined stop and deep clean flews. Cheeks are muscular and wrinkle-free. The muzzle is broad, square or blocky in shape, shorter than the skull length, with a straight top, reminiscent of the English Bulldog. Lower jaws are strong, deep, and wide. Eyes are moderate in size, oval or slightly rounded, set low and well apart, with all colours allowed except blue. Ears are high set, and the tail typically carries in a "pump handle" or "crank" position, tapering to the tip and level with the topline. The gait is confident and jaunty, reflecting alertness and excitement.
Gender Differences
Males generally demonstrate greater muscle mass and weight, often being more robust, whereas females tend toward a slightly lighter and more agile frame. Temperament-wise, males may show more dominant behaviours, making structured training and leadership crucial irrespective of gender.
Faults to Watch For: Exaggerations such as overly large heads disproportionate to the body, excessively short muzzles that impair breathing, weak jaws, undershot or wry bites, excessively bowed legs, splayed feet, bobbed or screw tails, and coat colours like merle are considered faults. Behavioral extremes including viciousness or extreme shyness are also faults under the United Kennel Club standards.
