The American Staffordshire Terrier descends from bull-and-terrier dogs brought from Britain in the mid-1800s. The AKC recognized the breed in 1936, and it sits in the Terrier Group. AmStaffs are stocky, medium-sized dogs, usually 40 to 70 pounds, with a broad head, pronounced cheek muscles and a short glossy coat in nearly any color.
Most are people-loving and playful, often leaning on or climbing onto a favorite person. Their strength and terrier persistence mean training and leash skills pay off, especially on Mansfield's sidewalks and park paths. Some AmStaffs are selective with other dogs even when well socialized, so calm, managed introductions matter. The coat needs little care beyond a quick brush and an occasional bath.
