The American Staffordshire Terrier should give the impression of great strength for his size, a well put-together dog, muscular, but agile and graceful, keenly alive to his surroundings. He should be stocky, not long-legged or racy in outline. His courage is proverbial.

Head
Medium length, deep through, broad skull, very pronounced cheek muscles, distinct stop; and ears are set high. Ears - Cropped or uncropped, the latter preferred. Uncropped ears should be short and held rose or half prick. Full drop to be penalized. Eyes - Dark and round, low down in skull and set far apart. No pink eyelids. Muzzle - Medium length, rounded on upper side to fall away abruptly below eyes. Jaws well defined. Underjaw to be strong and have biting power. Lips close and even, no looseness. Upper teeth to meet tightly outside lower teeth in front. Nose definitely black.

Back
Fairly short. Slight sloping from withers to rump with gentle short slope at rump to base of tail. Loins slightly tucked.

Body

The front legs should be straight, large or round bones, pastern upright. No resemblance of bend in front. Hindquarters well-muscled, let down at hocks, turning neither in nor out. Feet of moderate size, well-arched and compact. Gait must be springy but without roll or pace.

Coat
Short, close, stiff to the touch, and glossy.

Color
Any color, solid, parti, or patched is permissible, but all white, more than 80 per cent white, black and tan, and liver not to be encouraged.
