American Staffordshire Terriers descend from bull-and-terrier dogs brought from Britain in the mid-1800s, and the American Kennel Club recognized the breed in 1936. AmStaffs are stocky, muscular, medium-sized dogs, usually 40 to 70 pounds, with a broad head, a short glossy coat in nearly any color and a short, tapering tail.
Most are confident, affectionate and playful, 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 even when well socialized. The short coat needs little grooming but sheds moderately. That mix suits adopters who want a companion for daily walks and have time for training. Dogs vary, so the dog in front of you matters more than the breed label.
