On April 1, 2003, the AKC changed the name of the breed from Jack Russell Terrier to Parson Russell Terrier. This is to distinguish between the correct, longer legged dog and the shorter legged dog, often referred to as the pudding or shortie.
The Parson Russell Terrier is a working variant of the fox terrier. The breed personifies the type preferred and developed by Reverend John Russell, an avid fox hunter from the country Devon, England, during the nineteenth century. The dog was developed to "run with horse and hound" so that when the hounds drove a fox to ground the terrier followed, baying to bolt his quarry to the surface so the chase could continue. The breed remained popular with hunters and horsemen throughout the 20th century and in January of 1990, it was recognized in England by The Kennel Club.

Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree and its effect upon the health and welfare of the dog.
Any dog clearly showing physical or behavioural abnormalities shall be disqualified. Note: Male animals should have two apparently normal testicles fully descended into the scrotum.
