Jack Russell Terrier Dog Breed

Jack Russell Terrier Dog Breed
General Appearance:
The Jack Russell Terrier is a small, agile, brave, principally white-bodied terrier that is known for fox hunting and other small animals. The Jack Russell Terrier comes in two distinct variations: the long-legged version and the short-legged version. Short-legged Jack Russells are often called "shorties" and are recognized as the Russell Terrier, or Jack Russell Terriers, while the long-legged variation is called the Parson Jack Russell Terrier. They are both small dogs and can be a variety of wiry, smooth, and multicolored coats. They are predominantly white, with patches of brown and black, often covering part of the face. The Jack Russell Terrier has short drop ears and a tail that is usually cropped just long enough to grab it out of a fox hole. They are sturdy and muscular, well adapted to work hard. The smooth coat has an outer-coat that is short and stiff. In the rough coat the outer-coat is longer. The broken variety is used to describe both dogs with outer-coats of different lengths or dogs that have longer hair on specific parts of the body.

In 1819 a fox runner and member of the British Kennel Club by the name of Reverend John Russell came across a terrier who he developed into the Jack Russell Terrier over the course of sixty years until his death at the age of 88. He owned a crossbred terrier by the name of "Trump", which he bred with bull-and-terrier breeds that were used for bull baiting to increase tenacity and aggression towards prey. He then bred in foxhounds, as well as "pocket beagles", which helped in evening out the temper of the breed. John Russell wanted a breed that was small enough to go to ground after a fox, but wouldn't kill the prey. Often times, however, the breed's tenacity overtook their ability to corner the prey, and sometimes Jack Russell Terriers would kill the fox - taking away the sport for the hunters.
