Staffordshire Terrier Club of America - Official Amstaff Standard
American Staffordshire Terrier- Breed Standard.
"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.
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 half prick or rose. 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.
Heavy, slightly arched, tapering from shoulders to back of skull. No looseness of skin. Medium length.
"Dark and round, low down in skull and set far apart.
No pink eyelids" Dark eyes are essential to the proper expression. Light eyes are mentioned under "faults". Eye color should be brown, and as dark a shade as possible. The eyes are normal dog eyes, appearing fairly round, but not totally. They are not thin almond or triangular in appearance, but are set low down in the skull and deep. They should never protrude or bulge. They are of medium size, neither too small (piggy) nor over large.
The expression is very direct looking keen, confident, intelligent, courageous, never fearful or evasive.
"No pink eyelids" refers to the inner part of the eyelid. Although the author of the standard was not perfectly clear in this regard, he stated later that he meant thin eye rims, without pink mucous membrane showing. We feel this to be a valid interpretation of this point. No haws showing or loose rims. If you choose to also consider this to mean fully pigmented eye rims rater that pink ones, please treat pink eye rims as a cosmetic fault.
Strong and muscular with blades wide and sloping.
