Background:

The Jack Russell Terrier was developed by an English Clergyman, Parson Jack Russell in the 1800s as a fox hunter small enough to go to ground after the fox into his lair.  A seemingly smaller version of the Smooth Fox Terrier, the Jack Russell Terrier is currently listed as a miscellaneous class breed with the AKC awaiting acceptance into regular classes.

Personality:

Like most hunting terriers, the Jack Russell Terrier is valued more as a companion than a hunter.  A lively energetic dog, this breed is often dog aggressive and may not get along well with unfamiliar dogs.  Still somewhat rare in the US, it has gained greater recognition and notoriety since one of its breed started appearing in the popular TV series 'Frasier'.
