Breed Profile

The Jack Russell Terrier breed is a type of working terrier. Since their beginning, in the early 1800’s, the Jack Russell was bred strictly for hunting. The JRT is a unique, versatile working Terrier. He is an intelligent, loyal and affectionate dog, keen, alert and always ready to go. He is also a match for any cat in his ability to catch mice.

The JRT is adaptable, however, he was bred to be a hunting dog and, as such, does require plenty of outdoor activity and exercise. His unique personality makes him desirable to many, but city or apartment living or a sedate lifestyle does not meet the dog’s needs.

It should also be noted that Jack Russells can be aggressive toward other dogs and small animals including cats, gerbils, hamsters, guinea pigs, etc. The breed is fearless and known to take on an adversary twice or more his size.

His coat may be smooth or rough, white, white with black or tan markings, or white with a combination of these colours.

The Jack Russell is a happy, bold, energetic dog with a suprisingly gentle and kind nature.

Health Issues

If you are considering the adoption of a Jack Russell Terrier, or any breed, it is very important to be selective in choosing a responsible and reputable breeder. Ensure that the prospective puppy’s parents have all health clearances. Breeding of any dog should not be done until after they have been proven to be free of evidence of significant hereditary diseases. (For more information on selecting a breeder, see the articles on the main General Information page.)

Breed Standards

Note: Effective 1 April 2003, the American Kennel Club (AKC) changed the name of the Jack Russell Terrier to the Parson Russell Terrier. This name change was based on a request by the Jack Russell Terrier Association of America which is now known as the Parson Russell Terrier Association of America.

In Canada, the Canadian Kennel Club (CKC) recognizes the Parson Russell Terrier and the Russell Terrier.

In England, Ireland, and Australia, the longer-legged square dog is known as the Parson Russell Terrier while the lower, longer dog is called the Jack Russell Terrier.

The United Kennel Club recognized the short-legged dogs as Russell Terriers until January 1, 2009, when the breed name was revised to the Jack Russell Terrier.

The FCI recognizes 344 breeds, with each being the “property” of a specific country. The “owner” countries write the standards of these breeds in co-operation with the Standards and Scientific Commissions of the FCI, and the translation and updating are carried out by the FCI. The FCI is not a breed registry nor does it issue pedigrees.
