Jack Russell breed history

This characterful breed was developed in England by Parson John Russell in the 19th century, hence the name. He wanted to evolve a terrier which could hunt with hounds and drive foxes from their dens. Difficulties in distinguishing dogs from their prey made white dogs advantageous and it was also important that the dogs demonstrated tempered aggression. In other words, they needed to be keen to flush out prey but not to injure it. John Russell certainly succeeded in creating the desired traits and these feisty little dogs have been popular with sportsman ever since.

After Russell’s death, two men continued breeding programmes using dogs descended from John Russell’s terriers. Then, in 1894 Blake Heinemann created the first breed standard. Crossbreeding became prevalent as it did again after World War II when the requirement for hunting dogs declined. Breeders introduced new traits to the dogs and several breed clubs appeared in the UK. The Kennel Club established a new standard and recognised the breed in 1990 when its name was the Parson Jack Russell terrier. The Jack was dropped from the official name in 1999 but most people still use it.

What is the Jack Russell bred for?

The Jack Russell was bred to flush out foxes for huntsmen but not to injure them. They were evolved to move fast and to possess the stamina to cover long distances. Their white colour was developed to ensure that huntsman could always see them and distinguish them from prey.

What sort of owners does the Jack Russell suit?

Small and affectionate, Jack Russells appear to be the perfect pets and they can be exactly that. They are good with children if properly socialised and don’t require intensive grooming. However, they are demanding pooches that need constant attention and loads of exercise. They are best suited to active owners and life in the countryside. They excel at agility competitions. Jack Russells are amazing ratters and great companions for people who work outdoors. But if they don’t get the attention they need and burn off sufficient energy, they can be destructive.

Jack Russells are poor choices for apartment living due to their energy and tendency to bark a lot. They shouldn’t be left home alone and need firm handling. Their strong prey drive can run then into trouble and they may prove to be aggressive to dogs of the same sex. There’s no doubt about it, these dogs are demanding and should not be taken on lightly.
