Jack Russell Terrier

Fearless, clever and inexhaustible — a big dog in a small, springy body.

Jack Russell Terriers are bold, energetic hunting terriers with sharp minds. They are fun, affectionate companions for active owners, but they need lots of exercise, firm boundaries and secure fencing.

Recognised by the UKC and FCI. The AKC recognises the closely related Parson Russell Terrier and Russell Terrier.

Ratings describe typical dogs of the breed on a 1–5 scale. Individual dogs vary with lines, upbringing and training.

Temperament

JRTs are lively, confident and intensely curious. They love games, training and adventures and bond closely with their families. Their energy and intelligence make them excellent at agility and flyball.

They were bred to hunt foxes independently, so they dig, chase, bark and can be scrappy with other dogs. Boredom leads to destruction. They are not a low-maintenance small dog.

Living with a Jack Russell Terrier

Exercise

Needs an hour or more of vigorous exercise daily plus mental games. Excellent for dog sports.

Grooming

Weekly brushing; rough and broken coats may need hand-stripping. Moderate to heavy shedding.

Training

Very smart but independent. Keep training varied and fun. Recall and impulse control are essential.

Kids & other pets

Good with respectful older children. Often dog-selective and unsafe with small pets.

Time alone

Can be destructive or noisy when bored. Provide exercise and puzzle toys.

Home fit

Best suited to a house with secure outdoor space; apartment living is hard on this breed and its neighbours.

Health

With good breeding and care, a Jack Russell Terrier typically lives 13–16 years. These are the conditions most associated with the breed — not a prediction for any individual dog.

  • Primary lens luxation

    The lens dislocates, causing pain and glaucoma; DNA testing is available.

  • Patellar luxation

    Kneecaps that slip out of place are common in small terriers; severe cases need surgery.

  • Deafness

    Linked to white coats; BAER testing detects it.

  • Legg-Calvé-Perthes disease

    Degeneration of the hip joint in young small dogs.

  • Hereditary ataxia

    Spinocerebellar ataxia causes loss of coordination; DNA tests exist.

Ask a breeder for

  • Eye examination and primary lens luxation DNA test
  • BAER hearing test
  • Patella evaluation
  • DNA tests for spinocerebellar ataxia

Cost to own

After the first year, expect roughly $1,000–$2,000 a year for food, routine vet care, preventives, insurance and supplies (US estimate).

  • Pet insurance for a puppy typically runs $30–$60 a month; premiums rise with age and breed risk.

History

The breed is named after Reverend John Russell, a fox-hunting parson in Devon, who bought a white terrier named Trump in 1819. Trump became the foundation of his working terrier line.

Working terriers were bred for ability rather than looks, so the type varied. Kennel clubs later split the breed: the AKC recognises the Parson Russell (taller) and the Russell Terrier (shorter), while “Jack Russell” remains the common name.

Did you know?

  • Eddie from the sitcom Frasier was played by a Jack Russell named Moose.
  • Many JRTs can clear several times their own height — fences need to be taller than you think.
  • The breed’s white coat helped hunters tell the terrier apart from the fox.
