American Staffordshire Terriers descend from bull-and-terrier dogs brought 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.
In Brooklyn, the traits that matter most show up on the leash. AmStaffs are typically affectionate and eager to lean on their people, but they're strong and persistent, so loose-leash training pays off on crowded sidewalks. Some are selective with other dogs, which makes dog runs a case-by-case call. They're common in shelters and often overlooked, and the pit bull type label can affect housing and insurance.
