English standardAmerican Staffordshire Terrier

General Appearance	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 and Skull	Medium length, deep through, broad skull, very pronounced cheek muscles, distinct stop; and ears are set high.
Eyes	Dark and round, low down in skull and set far apart. No pink eyelids.
Ears	Cropped or uncropped, the latter preferred. Uncropped ears should be short and held rose or half prick. Full drop to be penalized.
Mouth	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.
Neck	Heavy, slightly arched, tapering from shoulders to back of skull. No looseness of skin. Medium length.
Forequarters	Strong and muscular shoulders with blades wide and sloping. The front legs should be straight, large or round bones, pastern upright. No semblance of bend in front.
Body	Well-sprung ribs, deep in rear. All ribs close together. Forelegs set rather wide apart to permit chest development. Chest deep and broad.
Hindquarters	Fairly short back, slight sloping from withers to rump with gentle short slope at rump to base of tail. Loins slightly tucked. Hindquarters well-muscled, let down at hocks, turning neither in nor out.
Feet	Feet of moderate size, well-arched and compact.
Tail	Short in comparison to size, low set, tapering to a fine point; not curled or held over back. Not docked.
Gait/Movement	Gait must be springy but without roll or pace.
Coat	Short, close, stiff to the touch, and glossy.
Colour	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.
Size	Height and weight should be in proportion. A height of about 18 to 19 inches at shoulders for the male and 17 to 18 inches for the female is to be considered preferable.
Faults	Faults to be penalized are: Dudley nose, light or pink eyes, tail too long or badly carried, undershot or overshot mouths.
