Pit Bull Terrier is a type more than a single breed. In Irving, as elsewhere, the label usually covers the American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, American Bully and many mixes with broad heads and muscular builds. All trace back to nineteenth-century British bull-and-terrier dogs, and breed labels on these dogs often don't match their DNA.
Most are medium-sized, around 30 to 65 pounds, with a short, smooth coat that sheds moderately. Many are affectionate, energetic and eager to please, though some are selective about other dogs. Because dogs of this type are so common, adopters often have adult dogs to choose from, and how a dog actually behaves tells you more than its label. A dog that's calm indoors once exercised fits Irving's mix of apartments and houses well.
