The Jack Russell terrier originated in Devonshire, England.

Date Of Origin

This breed was created in the mid to late 1800's.


The jack Russell takes its name form the Reverend John "Jack" Russell who bred a strain of terriers for working fox in Devonshire. The Jack Russell terrier today is very much the same as the original terrier that John Russell bred.
The breed has been the subject of debate among fanciers, with two breed clubs forming to promote differing philosophies. It is now called the Parson Russell terrier by the AKC and its parent club, the Parson Russell Terrier Association of America (PRTAA) which favors the longer legged dogs. The other breed club, the Jack Russell Terrier club of America (JRTCA), associated with the UKC, continues to refer to the breed as the Jack Russell terrier.


The Jack Russell terrier is a small to medium size, sturdy, and muscular dog. It has a flat skull and black nose. The almond shaped eyes are dark and the small, V-shaped ears fold forward. It is well balanced with a small chest and straight legs. Its short tail is carried erect. There is a short, smooth, or broken coat. There is always a minimum of 51% white on the body, with tan, black and brown markings.


This is a very assertive, loyal, keen and active dog with a great deal of intelligence and a strong work drive. It is often called a big dog in a small body.


Like all small terriers, it has been used for hunting small game in its lair. It was especially appreciated for the ability and rapidity with which it could borrow into small holes. A rather rare terrier, it has passes into the ranks of companion dog.

Health Concerns

Eye problems, deafness, Legg-Perthes disease, luxating patellas.
