Updated August 1, 20261 min readCited sources

The Staffordshire Bull Terrier is a small to medium-sized terrier breed from England, developed in the 19th century for blood sports but now kept as a companion dog.

What it is

Also called the Staffy or Stafford, this breed is muscular, compact, and athletic. It stands about 36–41 cm at the shoulder, weighs 11–17 kg, and has a short, smooth coat. Lifespan is roughly 12–14 years.

Why it matters

Originally bred for dog fighting, the Staffordshire Bull Terrier has since become known for its affectionate and loyal temperament. It is distinct from the American Staffordshire Terrier, though names are sometimes confused.

Key details

The breed was first recognized by The Kennel Club of Great Britain in 1935. Modern descriptions emphasize its people-oriented nature, but temperament depends on training and socialization. In Canada, it is present as a companion dog with no unique local history.
