Chapter 4

In most breeds, dog shows will judge them on appearance and their standard will directly relate to how the dog appears visually. This is not the case with the Jack Russell. Because it's a working Terrier, the Jack Russell is judged on its body dimensions and its ability to perform complex work tasks, not on their specific appearance. A key element in the evaluation of Jack Russell's is chest size. A strong barrel shaped chest that's still small enough to crawl into the den of any fox and work game from burrows is of the utmost importance.

The most common adversary of the Jack Russell is the Red Fox, which Reverend John Russell specifically created the modern day Jack Russell to hunt. The fox will make a home in any den hole available, whether it's their own burrow, a groundhog hold, a rabbit hole, even a vacant badger's den. They've also been known to live inside drain pipes and building crawl spaces. In any event, a proper Jack Russell must be small enough to chase a fox and fit into its home, no matter how small. Generally it is preferred for a Jack Russell to have a chest size that is no larger than that of the average fox. Around the world the average known red fox chest ranges from 12-14 inches, and a proper Jack Russell's chest should match that range accordingly. The weight of the average fox is 14 lbs., it's desirable to be able to match the weight of the fox as well, but a working Terrier will often exceed that number slightly because of the dense muscle that the breed is known for.
