American Staffordshire Terriers descend from the 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, pronounced cheeks and a short, glossy coat in nearly any color.
Many are confident, affectionate and goofy with their families, and they like to lean on or climb onto a favorite person. Their strength and enthusiasm make training and leash manners important, and some AmStaffs are selective with other dogs even when well socialized. In Amarillo, where no breed-specific rules apply, the practical questions are mostly housing and insurance. Every dog differs, so judge the dog in front of you by how it actually behaves.
