Pit bull

Pit bull is a term used for a group of dog breeds and related mixes rather than a single universally recognized breed.

By Ethan Anderson| Reviewed by Olivia Bennett, Standards & Fact-Checking Lead| Updated July 27, 2026|2 min read| Fact-checked

Pit bull is a term used for a group of dog breeds and related mixes rather than a single universally recognized breed. In common usage, it often refers to dogs with bulldog-and-terrier ancestry, especially the American Pit Bull Terrier, American Staffordshire Terrier, and Staffordshire Bull Terrier. The term is also used differently by kennel clubs and other organizations.

Definition and usage

Pit bull is used as an umbrella term for several dog breeds and mixes with similar ancestry or appearance. Different organizations and communities use the label in different ways.

Origins and history

Pit bull-type dogs developed in 19th-century Britain from bulldog and terrier stock. They were associated with bull-baiting and later dog fighting after those activities were outlawed.

Breed recognition

The American Kennel Club does not treat pit bull as a distinct breed, while the United Kennel Club recognizes the American Pit Bull Terrier. This contributes to inconsistent use of the term.

Public perception and terminology

The label is often used broadly in everyday speech and media, sometimes for dogs that are only similar in appearance. This has made the term controversial and imprecise.
