HISTORY
There are many records of the development of the Parson Russell Terrier however Jane’s Harvey’s www.janedogs.com gives the clearest concise picture.  Excerpts from Jane’s site tell us that “Prior to 1800 the generic name ‘Fox Terrier’ was given to any Terrier that was used to bolt foxes out of their burrows, particularly associated with the sport of Fox Hunting. Those which remained working Terriers whose ground colour was white were later developed into two separate breeds with differing leg length - the Jack Russell Terrier and the Parson Russell Terrier, both named after one man, the Parson Jack Russell. Meanwhile the name Fox Terrier became one of the first show dogs both in England and Australia. In England 1913 Fox Terriers were split into two separate pure-breeds separated by coat type - the Fox Terrier (Smooth) and the Fox Terrier (Wire).
The Reverend Jack (John) Russell was on the first board of the Kennel Club (UK) and one of the first Kennel Club judges despite his own dogs being specialized Fox Hunters rather than show dogs. At this time coats on both the show Fox Terriers and Jack Russell’s Terriers ranged from smooth through to the rough we see on Jack Russell to this day.
In England, by 1900 Fox Terriers had become pure show dogs, and bred quite separately from the Reverend Jack Russell’s working terriers.
 The ‘old type’ Fox Terriers continued to be bred from the Reverend John (Jack) Russell’s’ working lines selected for brains and a sound constitution. Although a Parson Jack Russell Terrier Club has existed in England right through the 1900’s, a breed standard written and even a class for ‘Working Fox Terriers’ provided at Crufts, the Parson (Jack) Russell Terrier was not separately recognized by the Kennel Club (UK) until 1990. Firstly it was called the Parson Russell Terrier and later the name was changed to the Parson Jack Russell Terrier. It differs from the Australian Jack Russell in that its ideal height is 14” for dogs and 13” for bitches”.
