American Staffordshire Terrier
Featured photoamerican-staffordshire-terrier.jpgThe American Staffordshire Terrier is a medium-to-large American terrier breed descended from the bull-and-terrier crosses brought to North America from England in the 19th century. Selected for strength, courage, and a stocky, muscular build, the breed was developed along a distinct American line from the 1880s onward and gained AKC recognition in 1936 as the Staffordshire Terrier — later renamed American Staffordshire Terrier in 1972 to distinguish it from the Staffordshire Bull Terrier. Males stand 43–48 cm and weigh 25–32 kg.

Origin
The American Staffordshire Terrier descended from bull-and-terrier crosses developed in early 19th-century England by crossing the Old English Bulldog with early terrier breeds to produce a dog combining the bulldog's tenacity and the terrier's agility. English and Irish immigrants brought these dogs to North America in the mid-19th century. American breeders diverged from the British Staffordshire Bull Terrier line, selecting for a larger, more powerful build. By the 1880s a consistent American type had emerged, and the first AKC registration followed in 1936.
Recognition
The UKC had registered the breed since 1898 under the name American Pit Bull Terrier — a separate, if closely related, registry track. The AKC recognised the breed in 1936 under the name Staffordshire Terrier, distinguishing it from the British Staffordshire Bull Terrier. When the AKC recognised the Staffordshire Bull Terrier in 1972, it simultaneously renamed the American variety American Staffordshire Terrier to avoid confusion. The FCI followed with recognition in 1971 (FCI No. 286).
Standard
The AKC standard describes a strong, stocky, well-built dog with a broad skull, pronounced cheek muscles, a strong underjaw, and a medium-length, rounded muzzle. The coat is short, close, stiff to the touch, and glossy. Any colour, solid or parti, is acceptable; solid white and more than 80% white, black-and-tan, and liver are undesirable in the standard but not disqualified. Males stand 43–48 cm and weigh 25–32 kg; females are slightly smaller and lighter.

Frequently asked questions
What AKC group does the American Staffordshire Terrier belong to?
The AKC places the American Staffordshire Terrier in the Terrier Group. Like all terrier breeds, it descends from dogs originally developed for earthwork and vermin control in the British Isles, though the AmStaff's specific ancestry involves bull-and-terrier crosses from 19th-century England. Within the Terrier Group, it belongs to the bull-type terrier subgroup alongside the Bull Terrier, Miniature Bull Terrier, and Staffordshire Bull Terrier.
How is the American Staffordshire Terrier different from the Staffordshire Bull Terrier?
The American Staffordshire Terrier (AmStaff) and the Staffordshire Bull Terrier (Staffy) share a common 19th-century English ancestor in the bull-and-terrier crosses. The AmStaff is considerably larger (43–48 cm, 25–32 kg) than the Staffy (36–41 cm, 11–17 kg). American breeders selected for a more powerful, heavier-boned dog than their British counterparts; the two populations diverged enough over the 19th–20th centuries to be formally recognised as separate breeds by the AKC in 1972.
When was the American Staffordshire Terrier recognised by the AKC?
The AKC recognised the breed in 1936 under the name Staffordshire Terrier. In 1972, when the AKC simultaneously recognised the Staffordshire Bull Terrier (a related but distinct British breed), the name was changed to American Staffordshire Terrier to distinguish the two. The UKC had maintained a separate but related registry for American Pit Bull Terriers since 1898.
