Jack Russell Terrier

Jack Russell Terrier is also called Working Russell Terrier, Working Jack Russell Terrier, or JRT. The dog is named after an English priest, Reverend John (Jack) Russell, who initially came up with it. In the earlier times, the dog was mainly kept for hunting fox. However, today the dog is kept mainly for its characters and aptitude and not for its type. It was the first dog to land on the North and South poles. This came about when Sir Ranulph Fiennes together with his wife, Ginnie, visited these poles with their JRT in 1979-1982, as they explored the earth.

JRT dogs are very intelligent, curious, and extremely entertaining. This dog however does not meet registration threshold for either English or American Kennel Club hence it is not registered. A mature JRT has a height of roughly 10-15 inches and a weight of 13-17 pounds. It comes in three different coat types that are smooth, broken, and rough; the coat is also waterproof and requires little care.


History and Health :

  • History :

Jack Russell Terrier came from Devonshire in England at around 1800’s. The dog came from an idea of John (Jack) Russell who took a “Trump” which looked like a Wire Fox Terrier but the legs were shorter and developed it. The “Trump”, a dog from which JRT was developed, is thought to have been a crossbreed between Black Tan Terrier and a Fox Terrier.

Mr. Russell developed this Terrier to help him in hunting fox. In his breeding, he concentrated on being consistent with the dog’s nature and not its color. With this breeding, he managed to come up with a dog small enough to enter into a fox den, flush it out, and then chase it on the ground. His terriers were very distinguished as they were exceptionally white with negligible black and or tan markings. After him passing away, his dogs gained popularity especially with sportspersons. They were highly crossbred with other dogs which generated many deviations in them hence denying them registration with The Kennel Club.
