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.
Height and weight should be in proportion.
A height of about 18-19 inches (46-48 cm) at shoulders for the male and 17-18 inches (43-46 cm) for the females is to be considered preferable.
