American Staffordshire Terriers descend from bull-and-terrier dogs brought from Britain to the United States 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.
Many AmStaffs are confident, goofy and devoted to their families, and they often lean on or climb onto a favorite person. Their strength calls for leash training and early socialization, and some are selective with other dogs. In West Des Moines, where neighboring Des Moines treats pit-bull-type dogs differently, it helps to know where you'll live and walk before you adopt.
