Jack Russell Terrier

The Jack Russell Terrier is named after the Reverend John Russell, a keen fox-hunting enthusiast in 19th-century southern England. The modern breed was finalised in Australia before being recognised by the Fédération Cynologique Internationale.

It worked underground, chasing foxes into their dens.

Energetic, curious and brave, the Jack Russell is a cheerful companion very attached to its family. It has a strong hunting instinct and can be stubborn.

It needs consistent, playful training and plenty to do to avoid barking and destruction.

This is a robust, long-lived breed. Kneecap luxation, some inherited eye diseases and deafness should be monitored.

Genetic tests exist for some conditions.

Food for small active dogs, in portions matched to its energy use, suits it.

Avoid too many treats.

It needs at least an hour of intense activity a day: running, ball games, agility and scent games.

Its hunting instinct means a lead outside fenced areas.

It can live in an apartment as long as it gets plenty of exercise every day. Watch out for cats and small animals in the neighbourhood.

Whether smooth or rough-coated, it needs weekly brushing. It sheds all year round.

Rough-coated dogs can be hand-stripped twice a year.
