American Staffordshire Terriers descend from bull-and-terrier dogs that British immigrants brought 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, a short glossy coat in nearly any color and a tapering tail.
Most are confident, people-loving and playful, and many like to lean on or climb onto a favorite person. They're strong, so leash manners and training matter on busy Kalamazoo sidewalks. Some AmStaffs are selective or intolerant with other dogs even with good socialization, so meetings need planning. Because the breed is often grouped with pit bull types, confirm housing and insurance rules before adopting.
