History:
Jack Russell Terriers originated with the Parson John Russell's working terriers. At least this is the story we have all been told over-and-over again. There are different versions of this story, depending upon which group or kennel club or breeder is telling it. And there is very little hard proof to go with each version.
In more recent years, you will hear the Jack Russell Terrier referred to and now registered as; Parson Russell Terrier & Russell Terrier (AKC); Jack Russell Terrier & Russell Terrier (UKC); Connemara Terrier (CTS); English Jack Russell Terrier (EJRTC); Jack Russell Terrier (JRTCA); And a myriad of other loose terms like; English Jack, Irish Jack, Irish Jacks, Irish Jack Russell, Miniature Jacks, Australian Jacks, Shorties, Shorty Jack Russells, Puddin’ Jacks and a few other terms.
The JRTCA (oldest Jack Russell Terrier club in America) writes:
"History of the Jack Russell Terrier - Jack Russell Terriers are a type, or strain, of working terrier; they are not pure bred in the sense that they have a broad genetic make-up, a broad standard, and do not breed true to type. This is a result of having been bred strictly for hunting since their beginning in the early 1800's, and their preservation as a working breed since. The broad standard, varied genetic background based on years of restricted inbreeding and wide outcrossing, and great variety of size and type, are the major characteristics that make this strain of terrier known as a Jack Russell. A Jack Russell Terrier, by any name, all exhibit similar characteristics due to similar origin yet may differ in height to length ratio. Temperaments also vary dramatically due to different terrier mixes involved in the breedings."
I like the JRTCA’s short, clear and to the point “History”. And I agree. Now let us break it down further and look at some interesting facts that begin to surface when one spends years researching and tracking down the Jack Russell Terriers origins. Let us look at what we know to be so ...And not waste time on legend and hearsay.

But It Wasn’t That Simple:
The Parson John Russell did not begin with two dogs, or a pack of dogs, breed them and then "viola" a breed was born. If one digs deep enough into the Jack Russell Terrier history, several interesting facts begin to surface:There were times the Parson worked and bred certain dogs and lines, only to later sell them all off. History also tells us he preferred strains of terriers with working "Fox Terrier blood". ...however, this did not come until much later in his breeding experiments. This is not the only type he ever bred. Sometimes he wouldn't be satisfied for one reason or another and would start all over again. Other times he held back his best dogs to mix with the new. Many times, he started all over from scratch. There are even documented periods during his life when the Parson had no dogs at all.
The parson John Russell did not begin with a couple of Fox Terrier influenced dogs and end with the same. Writing's by his own friends describe him as an impetuous person... He bought and sold dogs ALL THE TIME. And as time went on, he came to prefer a certain type. Later in life he may have preferred a terrier with more concentration of working Fox Terrier blood... but he did start as well as borrow from, other lines that later went in a direction of their own.
As his "type" of terrier became more popular, they began to spread across all of England and eventually into other lands - such as Ireland. By then, there were Englishmen and Irishmen who preferred a more manageable terrier and found this in some of the

The Connemara line is an Irish bred and influenced Jack Russell Terrier with little "Fox Terrier" influence. This doesn't mean they were not Fox WORKING or bred from dogs that "worked Fox". It means they have very little Fox Terrier blood (as we know the Fox Terrier breed today) bred into them. They look like one would expect a Jack Russell Terrier to look like - except their height to length ratio is slightly different. Instead of being near square or short and cobby, they

For more information and detailed, documented history: Read THE ULTIMATE JACK RUSSELL TERRIER - EDITED BY MARY STROM.All the nonsense started when the kennel clubs began to recognize the Jack Russell as a breed and not a type of terrier: When a kennel club recognizes a new breed, they must have a standard in place and they must have a history behind the new breed. This is why we now have people running around in a frenzy claiming the Jack Russell has one very specific history and standard. There is a lot more to the Jack Russell Terrier's rich history. They were never meant to be cookie-cutter dogs. They were a type of terrier not a breed. Jack Russell Terriers, by any name, should exhibit similar characteristics due to similar origin yet may differ in height to length ratio as well as temperament and drive.
Editorial review of this book:
"The Ultimate Jack Russell Terrier is our largest book on the breed to date and brings together an impressive panel of top authorities to give a total picture of the breed."
Chapter Two: The Parson's Terrier", Page #26. Here are some excerpts:
"Although he was living in the depths of the Devon countryside, John Russell did not limit his breeding program by using merely stud dogs that were living locally or were easily obtainable. Davie's described Trump as 'progenitress of that famous race of terriers' but there is no evidence as to which dog or, indeed dogs were used in the foundation of the dynasty. The county of Devon was known at that time for its own strain of white bodied rough-coated terriers - ...It has been suggested that she (Trump) was at some point mated to a rough-coated black & tan terrier. Later in life, the parson was to use some of the most famous Fox Terriers of the day on his bitches."
***It should be noted this information came directly from his biographer E.W.L. Davies.This is a small sample of and closer glimpse at some of what really went on during the development of the breed. Mary Strom did her own research as well as consulted eleven (11) other "experts" of the breed and its history. Today, some are trying to re-write the history behind the Jack Russell Terrier... But it doesn't make it so. Not all Jack Russell Terriers have the same amount of Fox Terrier influence. Still today in England and Ireland, a few lines of Jack Russell's with little Fox Terrier influence remain with a few faithful breeders of this old type and style.
Another great book that has a non-sensationalist view of the origin and history behind the Jack Russell Terrier is D. Brain Plummers: THE COMPLETE JACK RUSSELL TERRIER. Some excerpts from Plummers book;
"The Facts Behind the Legend - Having decided that the present-day white-bodied hunt terrier is not, or at the most only slightly, connected with the dogs of the Reverend John Russell, what are the dogs that we today call, for want of a better term, Jack Russell Terriers? ...Well the reader must first dispense with the notion sadly perpetuated in a great number of books that God created John Russell and terriers came into being.
The JACK RUSSELL TERRIER CLUB OF GREAT BRITAIN writes:“The Jack Russell Terrier is a fox hunting dog, developed in England in the 19th century. There were terriers of all descriptions hunting earth dwelling creatures for hundreds of years before the Reverend John (Jack) Russell developed his particular "strain" of hunting terriers. The Reverend lived in the mid-1800's in Devonshire. He maintained his dogs with a certain body style and temperament...”
We hope you will at least walk away from this article with a much keener understanding of what a fascinating and unique history is behind this truly unorthodox breed of dog, and that the real facts about Jack Russell Terriers are really more astounding than the fiction that's been written in more recent times.
