The American Bulldog is a powerful, athletic short-coated dog, strongly muscled, and well boned. The body is just slightly longer than tall. The head is large and broad, with a wide muzzle. Ears are small to medium in size, high set, and may be drop, semi-prick, rose, or cropped. The tail may be docked or natural. The American Bulldog comes in solid colors, white with colored patches, and brindle. Gender differences are well expressed in this breed, with males typically larger and more muscular than females. Honorable scars resulting from field work are not to be penalized. The American Bulldog should be evaluated as a working dog, and exaggerations or faults should be penalized in proportion to how much they interfere with the dog’s ability to work.

The essential characteristics of the American Bulldog are those which enable it to work as a hog and cattle catching dog, and a protector of personal property. These tasks require a powerful, agile, confident dog with a large head and powerful jaws. The American Bulldog is a gentle, loving family companion who is fearless enough to face an angry bull or a human intruder. Note: It is common for young American Bulldogs to be somewhat standoffish with strangers, and judges should not penalize this. By the time the dog is around 18 months of age, however, the breed’s normal confidence asserts itself.
