American Staffordshire Terriers descend from bull-and-terrier dogs brought to the United States from Britain in the 1800s, and the American Kennel Club recognized the breed in 1936. They're stocky, muscular, medium-sized dogs, usually 40 to 70 pounds, with a broad head, pronounced cheeks and a short, glossy coat in nearly any color. Shedding is moderate and grooming is simple.
Many AmStaffs are confident, affectionate and playful, and often lean on or climb onto a favorite person. They're strong and determined, so leash training matters, especially in a city where moose share the trails. Some are selective with other dogs even when well socialized, which shapes how you plan walks and introductions. Each dog varies, and AmStaffs are common in shelters and often overlooked.
