Summary

The American Staffordshire Terrier, popularly known as AmStaff, originated from the same ancestors as the English Staffordshire Bull Terrier but developed independently in the United States after the mid-19th century. Selected to be larger, more muscular, and more imposing than the British Staffie, it is today recognized by the FCI as a separate breed. Despite the media controversy that sometimes surrounds "bull type" breeds, the well-bred and socialized AmStaff is a docile, confident dog that is very attached to the family.
