Basic Info

The American Staffordshire Terrier is a breed of dog. The breed is descended from American dog fighting breeds and was intended to be a show strain of the American Pit Bull Terrier. Staffordshire Terriers were first recognized by the American Kennel Club in 1936. They are a member of the Terrier and Molosser groups. The American Staffordshire is a large dog that ranges from 16 to 19 inches at the withers, and weighs from 57 to 67 pounds. He is muscular and strong, and gives the impression of great strength and agility for his size. His chest is deep and broad, and his neck is heavy. He has a broad skull, pronounced cheek muscles, and strong jaws. His ears may be half prick, rose, or cropped. The coat is short and glossy and can be of any colour although all white, mostly white, liver, and black and tan are not encouraged. His nose must be black.



These dogs should be courageous and tenacious. They are friendly towards humans. They should not be suspicious of strangers, and because of this are not necessarily good guard dogs. Similarities to other Bull Terriers. The American Staffordshire and the American Pit Bull Terrier are closely related breeds, sharing a common ancestry as recently as the early 1900s. The main physical difference between the breeds is that the American Staffordshire is not permitted to have red ("Dudley") nose leather, whereas American Pit Bull Terriers may have nose leather of any color, including red, black and blue. The American Staffordshire Terrier is also often of larger bone structure, head size and weight than their American Pit Bull Terrier cousins. In terms of temperament, the Staffordshire Terrier is accepted to be less tenacious and non-dog aggressive (non "game") than the American Pit Bull Terrier. The Staffordshire Terrier is a much larger and heavier dog than the English Staffordshire Bull Terrier, to which it is also closely related.
