The American Staffordshire Terrier, also known as Amstaff (in the United States), is a medium-sized, short-coated American dog breed. It is one of several breeds commonly known as pit bulls. In the early part of the twentieth century the breed gained social stature and was accepted by the American Kennel Club in 1936. The name was changed to reflect difference from the Staffordshire Bull Terrier of England.
According to the American Kennel Club "The Am Staff is a people-oriented dog that thrives when he is made part of the family and given a job to do. Although friendly, this breed is loyal to his own family."
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. Height and weight should be in proportion. A height of about 18 to 19 inches (46 to 48 cm) at shoulders for the male and 17 to 18 inches (43 to 46 cm) for the female is to be considered preferable.
American Staffordshire Terrier pups should not be bought weaned before they are 8–10 weeks old. Their life expectancy is generally 12 years with good care. The breed may be vulnerable to skin allergies, urinary tract infections (UTI), and autoimmune diseases. Spondylosis and osteoarthritis are common in older dogs.
