This breed was named after the clergyman named Reverend John Russell and was originally used in the middle part of the 19th century as a small game hunting dog. The tenacity and agility of the Jack Russell Terrier made it ideal for tracking and retrieving animals such as red foxes and badgers. Breeders emphasised the working ability of the Jack Russell Terrier, which made the standard very broad. In 2003 the Jack Russell Terrier Association of America became the Parson Russell Terrier Association of America.
