American Staffordshire Terrier

Breed Characteristics

Excellent watch and guard dog. Can be protective. Some individuals are able to climb almost as well as a cat. The American Staffordshire Terrier has a very high tolerance for pain. Comparatively less noisy than many other terriers. If carefully bred and correctly trained, this loyal dog is a wonderful pet; however, he is not for the novice or timid owner.

Is the American Staffordshire Terrier approved as a pet in a Singapore HDB flat?



United States, 1800s; ancestors, along with the Bulldog, Bull Terrier, and Staffordshire Bull Terrier, came from England. After dog fighting was banned in the United States in 1900, two strains of these dogs were developed, a show strain and a non-show strain. The show strain was labelled the American Staffordshire, while the non-show dog strain was labelled the American Pit Bull Terrier. The two are now being recognised as separate breeds.
