American Staffordshire Terriers descend from the bull-and-terrier dogs brought from Britain in the 1800s, and they joined the AKC Terrier Group 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, affectionate and goofy with their families, and they're smart enough to get bored fast. Some are selective or intolerant with other dogs, even with good socialization, so introductions deserve care. In Bismarck's long cold season, indoor games, puzzle toys and short training sessions matter as much as outdoor walks. Every dog differs, and how a particular dog actually behaves says more than its breed reputation.
