Pit Bull Terrier is more of a type than a single breed. The label usually covers the American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, American Bully and mixed dogs with similar broad heads and muscular builds, all descended from nineteenth-century British bull-and-terrier dogs. Shelter breed labels for these dogs are often wrong, so a dog's behavior tells you more than its listing.
Most weigh 30 to 65 pounds and have short coats that shed moderately. Many are affectionate, energetic and eager to please, though their strength means training and socialization matter, and some are selective about other dogs. In Missoula, where weekends often mean a trail or a river path, a dog that wants company and activity tends to fit in, as long as leash rules are followed.
