# American Staffordshire Terrier

The American Staffordshire Terrier, also known as the AmStaff, is a medium-sized, short-coated American dog breed recognized by the American Kennel Club, but not the United Kennel Club, which instead allows American Staffordshire Terriers to be registered under the American Pit Bull Terrier breed.
The height of an American Staffordshire Terrier is 18–19 in (46–48 cm) tall and weighs between 40–70 lb (18–32 kg). The American Kennel Club (AKC) describes the breed as "confident, smart and good-natured". American Staffordshire Terriers are not to be confused with American Pit Bull Terriers, though the American Pit Bull Terrier has similar ancestry they are two distinct breeds. It also should not be confused with the "Staffy" Staffordshire Bull Terrier of the United Kingdom.

## History

Some varieties of the extinct bull-and-terrier dog from the British Isles began to find their way into America as early as 1850. This varieties became a breed recognized by the United Kennel Club as American Pit Bull Terrier in 1898. In 1936 the American Kennel Club accepted to recognized the breed with a different name and registered a some individuals in the stud book. The name Staffordshire Terrier was approved because the ancestors of the breed was claimed to originally came from Staffordshire, England, a statement inspired by the recognition in 1935 of the related counterpart breed in England as the british Staffordshire Bull Terrier by the british Kennel Club. The name of the american AKC registered breed was revised on January 1st 1969 and changed to American Staffordshire Terrier to distinguish it from the british Staffordshire Bull Terrier.
The AKC closed and opened the AmStaff Stud Book to UKC registered American Pit Bull Terrier dogs a few more times until the 1970s. Since then both sire and dam had to be AKC registered dogs in order to register its offspring as American Staffordshire Terriers. The breed selection was based entirely on conformation and established breed standards that for decades has transformed the American Staffordshire Terrier into a much different breed from the American Pit Bull Terrier.

## Temperament

According to the American Kennel Club, these dogs are "smart, confident, good-natured companions. Their courage is proverbial. A responsibly bred, well-socialized AmStaff is a loyal, trustworthy friend to the end."
The official breed club of America points out that dog aggression can occur even if the dogs have been well-socialized and that therefore they should not be left alone with other dogs.

He should be stocky, not long-legged or racy in outline. His courage is proverbial." His head should be medium in length with a broad skull, a distinct stop, and pronounced muscles in the cheek.
