Pit Bull Terrier is a label for a type of dog more than a single breed. It can cover the American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, American Bully and mixes with similar broad heads and muscular bodies. All trace back to nineteenth-century British bull-and-terrier dogs, and DNA tests show that shelter labels are often wrong.
Most are medium-sized, around 30 to 65 pounds, with a short coat that sheds moderately and needs little more than a weekly brushing. Many are affectionate, athletic and eager to please, though some are selective about other dogs. In Oshkosh, where leashed walking is the rule in city parks, that mix of strength and enthusiasm makes early leash training worth the effort.
