Small body, massive personality. The Jack Russell Terrier (JRT) is one of the feistiest little dogs you’ll ever meet. Originally bred in England to bolt foxes from their dens, these pint-sized dynamos are fearless, clever, and full of beans.
They’re loyal companions, cheeky comedians, and occasionally chaos on four legs.
Owner insight: “Very high energy level. Very high prey drive. Need a lot of socialising. Intelligent, easily bored. My friend’s JRT went missing down a rabbit hole & was gone a week. Much crying and digging later he appeared of his own accord.”
Still not sure you’re ready for all that energy? Take the Which Dog Breed is Best for Me? Quiz to see if you can keep up with a JRT.

Exercise
If you want a lapdog, look elsewhere. Jack Russells are working terriers with stamina and prey drive — they need proper outlets for their boundless energy.
They need:
- At least 1–2 hours of exercise a day.
- Off-lead runs in safe areas (though recall is hit-and-miss).
- Mental stimulation — puzzle toys, training, and jobs to do.
Owner insight: “She was barky but not excessively so, and very affectionate and ‘bright’ — hated cats. Very curious, and could shriek her head off if very excited. Very active.”
Working Breed Warning
Jack Russells were bred to work underground and chase quarry — they haven’t forgotten it. Expect digging, chasing, and endless energy unless you give them structured outlets.
Pickles’ Aside: “A bored JRT will redecorate your garden faster than you can say ‘stop digging.’”
Temperament
Bold, clever, and hilarious — but not for the faint-hearted. Jack Russells are endlessly curious and thrive on adventure.
- Affectionate with their people.
- Suspicious of cats (and sometimes postmen).
- Vocal and dramatic when excited.
Owner insight: “I have a 9 year old female JRT called Pixie, she is an absolute dream, she loves life, she loves people, she loves adventures, she loves eating.”
Training
Jack Russells are extremely intelligent — which means they can be stars at training, or tiny terrors if you let them rule the roost.
- Positive reinforcement is essential.
- Consistency — don’t let bad habits slide.
- Recall work from day one — prey drive is strong.
Owner insight: “JRTs are EXTREMELY smart … many owners believe they understand.”

Strangers & Watchdog Potential
JRTs may be small, but they’re fearless watchdogs. They’ll alert you to anything unusual — and often keep barking just in case you didn’t hear.
- Excellent little watchdogs.
- Protective but not usually aggressive.
- Quick to sound the alarm.
Other Animals
Cats? Usually not. Rabbits? Definitely not. Jack Russells have prey drive running through their veins, though they can get on fine with other dogs when socialised early.
- Best with dogs raised together.
- Cats usually chased, not cuddled.
- Small pets are a risky match.
Pickles’ Aside: “Neighbours’ cats beware — the JRT patrol is out.”
Grooming
Low-maintenance, high-energy. JRTs come in smooth, rough, or broken coats, all of which are easy to care for.
- Weekly brushing is plenty.
- Seasonal shedding, but nothing dramatic.
- Occasional bath after muddy adventures.
Health
Jack Russells are generally hardy, often living into their teens. Still, a few health issues crop up:
- Patellar luxation (knee problems)
- Eye conditions like cataracts
- Deafness in some lines
- Legg-Calve-Perthes disease (hip joint issues)
They typically live 13–16 years — a long time for a dog with this much personality! Choose responsibly bred pups — see our Best in Breeder Guide for what to ask.
Cost of Ownership (UK)
Small dogs don’t cost as much as giants, but JRTs still rack up expenses through food, vet care, and toy replacement (they shred them).
- Puppy price: £700–£1,200
- Food: £20–£40/month
- Insurance: £15–£30/month
- Routine vet care: ~£200–£300/year
Famous Owners & Moments

- Eddie the JRT in Frasier.
- Wishbone, star of his own children’s series.
- Beloved companions for many countryside families in the UK.
