The American Staffordshire Terrier traces its ancestry to the bull-and-terrier dogs developed in 19th-century Britain by crossing Bulldogs with terriers. Some of these dogs were brought to the United States, where breeders gradually developed a larger and heavier type than the Staffordshire Bull Terrier that remained in Britain. Early American dogs were used for several purposes, including farm work, guarding, hunting, and companionship, although their ancestry also includes dogs bred for fighting. As organized breeding developed, enthusiasts increasingly focused on a standardized show and companion dog. The American Kennel Club recognized the breed in 1936 under the name Staffordshire Terrier. To distinguish it more clearly from Britain's smaller Staffordshire Bull Terrier, the name was changed to American Staffordshire Terrier in 1972. The breed shares historical roots with dogs that later became known as American Pit Bull Terriers, but the two populations developed under different registries and breeding priorities. Modern AmStaffs are substantial, athletic terriers whose physical strength reflects their ancestry, while established breed standards emphasize confidence and a stable temperament around people.
