The American Kennel Club-registered American Staffordshire Terrier began as the show-ring bound pit bull terrier. The American Staffordshire Terrier stems from like bull-and-terrier lines, and its ancestors were undoubtedly employed as canine wrestlers, that is, as fighting dogs. Today the type and stature of the Staffordshire breed cannot compare to the pit bull. The breed today is kind and loving with strong instincts. As a watchdog and guardian, the Staff is surely to be reckoned with. In size, the American Staffordshire Terrier is 17-19 inches tall at the shoulder and weighs 40-50 pounds. A variety of colors abound and a white ground color is very common. The ears of the breed are often cropped, but this practice will likely give way in coming generations.
