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 them in 1936. They're stocky, muscular, medium-sized dogs, usually 40 to 70 pounds, with a broad head, a short glossy coat in nearly any color and a tapering tail. Grooming is simple: a regular brushing and a bath every month or two, or when the dog gets dirty.
Most are confident, affectionate and playful, and they tend to bond closely with their families. They're strong, so leash manners and training matter on crowded sidewalks and at busy dog parks, and some AmStaffs stay selective with other dogs even when well socialized. They're common in shelters and often overlooked, so meeting a dog in person tells you more than reputation does.
