The Jack Russell was named after Reverend John Russell who first created the breed from a white-coated Fox Terrier. First appearing in the UK during the 1800s, the breed was further developed in Australia and America resulting in the Russell Terrier and Parson Terrier.

Jack Russells were bred to be a working dog. Originally bred to bolt foxes from their dens during hunts. They are still highly skilled hunters. After WW2, the requirement for Jack Russell Terriers as hunting dogs fell, but as pets they became steadily more popular in the UK. They were bred with Corgis, Chihuahuas and other smaller breeds of terrier. The offspring of these crosses became known as “Puddin’ Dogs” or “Shortie Jacks”. Tail docking Jack Russells was common to avoid them getting caught or broken down rabbit holes. But it is no longer allowed in the UK and there are heavy fines involved if a JRT’s tail has been docked.
