A broken-coated dog may have longer hair on the tail or face than that which is seen on a smooth-coated dog. 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 10 cm (5 in) in order to provide a sufficient hand-hold for gripping the terrier.The Jack Russell should always appear balanced and alert. As it 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, so the working Jack Russell must be small enough to pursue it.
