Jack Russell Terrier [SEP] Temperament
Jack Russells are first and foremost a working terrier. Originally bred to bolt foxes 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 will not bark but will expect attention to 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.
