Jack Russell Terrier

The Jack Russell terrier is a small terrier that has its origins in fox hunting. It is principally white-bodied smooth, rough or broken–coated which is commonly confused with the Parson Russell terrier (the American Kennel Club (AKC) and affiliate variant) and the Russell terrier (a shorter legged, stockier variety) with the term "Jack Russell" commonly misapplied to other small white terriers. The Jack Russell terrier is a broad type, with a size range of 10–15 inches (25–38 cm), the Parson Russell is limited only to a middle range with a standard size of 12–14 inches (30–36 cm), while the Russell terrier is smaller at 8–12 inches (20–30 cm), however each breed has different physical proportions according to the standards of their breed clubs.
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. Originating from the dogs bred and used by Reverend John Russell in the early 19th century from the English White terrier, they have similar origins to the modern Fox terrier. The Jack Russell is a high energy breed which relies on a high level of exercise and stimulation, and does not have a great deal of serious health complaints. It has gone through several changes over the centuries, with changes in use and the formation of different conformation show standards by different kennel clubs. Recognition for the breed by kennel clubs has been opposed by the breed's parent societies – something which resulted in the creation and recognition of the Parson Russell terrier. Jack Russells have appeared multiple times in film, television and print with several historical dogs of note.

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. 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. They have a tremendous amount of energy for their size, a fact which can sometimes lead to trouble involving larger animals. They may seem to never tire and will still be energetic after their owner has called it a day. While socialized members of the breed are friendly towards children, they will not tolerate abuse even if it is unintentional.
