A puppy of the breed.

The Staffordshire Bull Terrier is a medium-sized, stocky, and very muscular dog with athletic ability, with a similar appearance to the much larger American Staffordshire terrier and American pit bull terriers. They have a broad head, defined occipital muscles, a relatively short foreface, dark round eyes and a wide mouth with a clean scissor-like bite (the top incisors slightly overlap the bottom incisors). The ears are small. The cheek muscles are very pronounced. Their lips show no looseness, and they rarely drool. From above, the head loosely resembles a triangle. The head tapers down to a strong well-muscled neck and shoulders placed on squarely spaced forelimbs. They are tucked up in their loins and the last 1-2 ribs of their ribcage are usually visible. Their tail resembles an old fashioned pump handle. Their hind quarters are well-muscled and are what give the Staffy drive when baiting. They are colored brindle, black, red, fawn, blue, white, or any blending of these colors with white. White with any color over an eye is known as piebald or pied. Skewbald is white with fawn patches. Liver-colored and black and tan dogs sometimes occur but are rare. The coat is smooth and clings tightly to the body giving the dog a streamlined appearance.

The dogs stand 36 to 42 cm (14 to 17 in) at the withers and weigh 14 to 18 kg (31 to 40 lb) for males; bitches are 11 to 15.4 kg (24 to 34 lb).^[2]
