Pit Bull Terrier is a label more than a single breed. In Saint Paul, as elsewhere in the US, it usually covers American Pit Bull Terriers, American Staffordshire Terriers, Staffordshire Bull Terriers, American Bullies and mixed dogs with similar broad heads and muscular builds. All trace back to nineteenth-century British bull-and-terrier dogs, and DNA studies show these labels are often wrong, so the name tells you little about any one dog.
Most are medium-sized, roughly 30 to 65 pounds, with a short coat that sheds moderately. Many are affectionate and eager to please, and they like to be wherever their people are. They're strong, so training and socialization matter, and some are selective about other dogs, which is worth remembering at busy dog parks. Adult dogs show their size and manners up front, which makes matching easier.
