Pit Bull Terrier is more a type than a single breed. The label usually covers American Pit Bull Terriers, American Staffordshire Terriers, Staffordshire Bull Terriers, American Bullies and mixed dogs that share their broad heads and muscular builds. All trace back to nineteenth-century British bull-and-terrier dogs, and DNA tests often disagree with the breed labels dogs are given.
Most are medium-sized, around 30 to 65 pounds, with a short, smooth coat and moderate shedding. Many are affectionate and eager to please, and they're strong enough that training and careful introductions matter. In Brockton that means good leash manners on busy sidewalks and a winter plan, since the coat offers little insulation. Because the type is so common in shelters, adopters often meet adult dogs whose personalities are already easy to read.
