American Staffordshire Terriers descend from bull-and-terrier dogs brought from Britain in the 1800s, and the AKC first recognized them 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.
Many AmStaffs are confident, people-loving and goofy with their families, and they often try to lean on or climb onto a favorite person. Their strength calls for training and leash manners, and some are selective with other dogs no matter how they're raised. Dogs vary, so a calm, patient routine matters more than reputation. AmStaffs are common in shelters and often overlooked, which is worth knowing if you're open to a less obvious match.
