Jack Russell Terrier Dog Breed Information

The Jack Russell Terrier is a small, principally white-bodied, smooth- or rough-coated terrier that has its origins in fox hunting. The name "Jack Russell" has been used over the years to describe a wide array of small white terriers, but now after a drawn-out legal battle, the JRTCA (Jack Russell Terrier Club of America) and its affiliates have won the exclusive rights to use the name Jack Russell Terrier to describe their particular variant of the dog, in the US. Commonly confused with the Parson Russell Terrier -- the AKC and affiliate variant -- and the Russell Terrier (a shorter legged, stockier variety), the working Jack Russell Terrier is a unique terrier which has been preserved in working ability as well as appearance much as it existed over 200 years ago.

Jack Russell Terrier History

The small white-fox working terriers we know today were first bred by the Reverend John Russell, a parson and hunting enthusiast born in 1795. In his last year of university at Oxford, he bought from the milkman a small white and tan terrier female called Trump. Trump was purchased based upon appearance alone. (Burns, 2005) She was the basis for a breeding program to develop a terrier with high stamina for the hunt as well as the courage and formation to chase out foxes that had gone to ground. An important attribute in this dog was a tempered aggressiveness that would provide the necessary drive to pursue and bolt the fox without resulting in physical harm to the quarry, effectively ending the chase, which was considered unsporting. This line of terriers developed by John Russell was well respected for these qualities and his dogs were often taken on by hunt enthusiasts. It is unlikely, however, that any dogs alive today are descended from Trump, as Russell was forced to sell all his dogs on more than one occasion because of financial difficulty, and had only four aged (and non-breeding) terriers left when he died in 1883.

While Trump's appearance is without detail, and her size is a complete mystery, the fox dens of Devon, England, where John Russell once hunted, are well known. Terrierman Eddie Chapman, who has hunted those same Devon earths for more than 30 years, notes that "I can state categorically that if given the choice, ninety-nine percent of hunt terrier men would buy an under 12" worker, if it was available, over a 14" one."

Jack Russell Terrier Appearance

Jack Russells are sturdy and tough, measuring between 10" and 15" at the shoulder. The body length must be in proportion to the height, and the dog should present a compact, balanced image. Predominantly white in coloration (more than 51%) with black and/or tan markings, they exhibit a smooth, broken or rough coat. The skin can sometimes show a pattern of small black or brown spots -- referred to as "ticking" -- that do not carry through to the outer coat. All coat types should be dense double coats that are neither silky (in the case of smooth coats) nor woolly (in the case of rough coats). The head should be of moderate width at the ears, narrowing to the eyes, and slightly flat between the ears. There should be a defined but not over pronounced stop at the end of the muzzle where it meets the head, and a black nose. The jaw should be powerful and well boned with a scissor bite and straight teeth. The eyes are almond shaped and dark colored, and should be full of life and intelligence. Small V-shaped ears of moderate thickness are carried forward on the head. When the dog is alert, the tip of the V should not extend past the outer corner of the eyes. The tail is set high and in the past was docked to approximately five inches in order to provide a sufficient hand-hold for gripping the terrier. It is a serious fault for the dog to have its tail down when in the show ring. The Jack Russell should always appear balanced and alert. As the Jack Russell is primarily a working terrier, its most important physical characteristic is its chest size, which must not be so large that it prevents the dog from entering and working in burrows. The red fox is the traditional quarry of the Jack Russell Terrier (JRT), so the working Jack Russell must be small enough to pursue its quarry. Red foxes vary in size, but across the world they average about 14 pounds in weight and have an average chest size of 12-14 inches at the widest part.

Jack Russell Terrier Temperament

Jack Russells are first and foremost a working terrier. Originally bred to bolt fox from their dens during hunts, they are used on numerous ground-dwelling quarry such as groundhog, badger, and red and grey fox. The working JRT is required to locate quarry in the earth, and then either bolt it or hold it in place until they are dug to. To accomplish this, the dog must bark and work the quarry continuously. Because the preservation of this working ability is of highest importance to most registered JRTCA/JRTCGB breeders, Jack Russells tend to be extremely intelligent, athletic, fearless, and vocal dogs. It is not uncommon for these dogs to become moody or destructive if not properly stimulated and exercised, as they have a tendency to bore easily and will often create their own fun when left alone to entertain themselves.

Their high energy and drive make these dogs ideally suited to a number of different dog sports such as flyball or agility. Obedience classes are also recommended to potential owners, as Jack Russells can be stubborn at times and aggressive towards other animals and humans if not properly socialized (a process that should be continued throughout their whole lives). Despite their small size, these dogs are not recommended for the condominium or apartment dweller unless the owner is ready to take on the daunting task of providing the dog with the necessary amount of exercise and stimulation. These are truly big dogs in small packages, a fact which can sometimes lead to trouble involving larger animals. The JRT owner must be aware of these tendencies and keep an eye out for trouble in many situations.

Jack Russell Terrier Care

Jack Russell Terrier Grooming

The Jack Russell Terrier does not require special grooming.

You can generally get by with a daily brushing and a bath carried out at home whenever his coat takes on a yellowish cast. There is no need for professional grooming or fancy cuts.

Jack Russell Terrier Exercise Needs

The Jack Russell Terrier is high energy.

This dog breed was bred to be a working dog which means the Jack Russell needs to stay active. If you do not have the time or energy to devote to daily walks and exercise sessions, this may not be the breed for you.

Jack Russell Terrier Training

Training your JRT is essential and it's advisable that you start your Jack Russell training as young as his early puppy years. Jack Russell puppy obedience classes will do wonders for helping, not only your puppy learn, but also assist you in learning about your new puppy. In addition to puppy and basic obedience classes for your Jack Russell Terrier, you might also consider enrolling him in some agility classes and competitions to help him expend excess energy.

Is a Jack Russell Terrier Right For You?

The Jack Russell is generally not good with other pets, so those pet owners who's family members already include those of the canine, feline or rodent persuasion may want to consider a more placid dog breed.

Due to it's high prey drive, Jack Russell has a tendency to be aggressive with other dogs and can be particularly unfriendly towards cats. If you have other dogs in your household, you may want to reconsider adopting a Jack Russell.

The Jack Russell Terrier is not a good apartment dog since the breed thrives on activity. This breed is better suited to dog owners that have plenty of space for their JRT to make use of; a large, well-secured yard is preferable. Country living is ideal for this dynamic dog breed.

A Jack Russell Terrier can be an excellent choice in dog breed if you are looking for a loving family pet and have the time, energy and space to devote to exercise and training. Caution is in order if you have other pets in your household. A Jack Russell Terrier adoption may be ideal for a household that only wants just one pet (or a pack of Jack Russells! :-)
