Breed history in brief

The origin of the Staffordshire Terrier American breed goes back to Great Britain where the dogs were bred for fighting, among themselves or against other more robust animals. In the mid-19th century, the Staffordshire Terrier was exported to the United States, where it is believed to have been crossed with breeds such as the White English Terrier and the Black-and-Tan Terrier (now extinct). The result was a larger dog than the English version. Even so, it was not until 1936 that the American Kennel Club (AKC) recognized the American Staffordshire Terrier as a unique breed. In the United States, the breed was developed for various purposes such as herding, hunting or guarding. In the 20th century, the American Staffordshire Terrier gained popularity, however, its origins still defined it as an aggressive dog. Today, the American Staffordshire Terrier is a common breed, recognized for its loyalty and affection and used for different functions such as: search and rescue dog, therapy dog and family companion.

The Staffordshire Terrier American shows a deep, broad chest and a short, slightly sloping back from withers to croup. The head is of medium size, with well marked cheek muscles and dark, round, wide-set eyes. The ears are high set and preferably uncropped. The tail is short, low set and tapers as it reaches the tip.

In addition, they are characterized by being loyal and protective.
