Bold, quick and keen to chase
Jack Russell Terriers were bred to work foxes. They needed to follow a scent independently, react quickly and keep going in tight spaces. Outdoors, that history often shows in the nose: a mouse in the hedge or a cat suddenly running past can be more compelling than a familiar cue.
Practise recall where distractions are modest and reward the dog well for turning away from a scent. A long line gives it room to explore while that skill is still developing. If it comes back after a delay, praise is more useful than scolding; you want returning to you to remain a good choice.
Everyday life
The UK veterinary charity PDSA recommends at least an hour of exercise each day. Divide that between walks with plenty of sniffing and a chance to run in a safely fenced area. Many Jack Russells also enjoy scent games. A hidden toy or a few short food trails give that keen nose something to investigate and can be offered indoors on a wet day.
If you keep rabbits or guinea pigs, provide secure enclosures and keep their space separate from the terrier's. Its prey drive can be strong even around household pets; do not count on it losing interest. After lively play, this busy terrier still needs somewhere it can rest without being disturbed.
Staying home alone
Dogs learn to stay home alone in small steps. The RSPCA advises no more than four hours at a time. Puppies and dogs that become unsettled when left alone need shorter absences and gradual practice. Arrange someone to care for your dog when you will be away longer.

Day-to-day care
Jack Russells may have smooth or rough coats; the mixed form is called a broken coat. All three shed and protect the dog against the weather. A thorough weekly brushing removes loose hair, with extra attention during seasonal shedding. After a walk through tall grass, check the rougher areas for burrs and twigs that can catch in the coat.
A rough coat may benefit from occasional professional hand-stripping. This removes mature, loose outer hair rather than simply clipping it short. Ask a groomer what suits your dog's particular coat, and get the dog used to calm brushing and handling of its paws early on.
Size and build
The Jack Russell Terrier is small and sturdy, with a body that is slightly longer than it is tall. The breed standard gives a shoulder height of 25 to 30 cm. Its chest is deep but narrow enough for the confined spaces in which the breed was originally expected to work. The legs should not look shortened in proportion to the body. Smooth, rough and broken coats are all recognised, each with a weather-resistant outer layer.

Health
Knees, eyes and coordination are important health topics for Jack Russell Terriers. With patellar luxation, the kneecap slips out of place and the dog may hold up a hind leg for a few steps. Primary lens luxation affects the eye instead: the lens moves out of position and can quickly cause severe pain and sight loss. A suddenly red or tightly shut eye needs urgent veterinary attention.
PDSA also lists two inherited forms of ataxia that worsen balance and coordination, and Legg-Calvé-Perthes disease, a painful condition affecting the top of the thigh bone. Breeding tests exist for lens luxation and the forms of ataxia. If you are considering a puppy, ask for the parents’ results and about limping, eye disease or an unsteady gait in the family. The results show which of these risks were checked in the parents.

Small Australian wire coated terrier
Australian Terrier
The Australian Terrier is a small, alert dog that enjoys getting out and exploring. Its harsh coat and distinctive neck ruff reflect a working background. At home it often wants to be close to its people, while a scent or a small animal can capture its attention outdoors.
Terrier
Border Terrier
A small, hardy terrier with a strong appetite for activity. It loves sniffing, digging and games, but a whiff of wildlife can put recall to the test.
Small English terrier with upright ears
Norwich Terrier
The Norwich Terrier packs plenty of enthusiasm into a short legged body. This small dog with upright ears was once valued as a ratter. Walks together, scent games and friendly training suit it well today. Its harsh coat needs more attention than its compact size might suggest.
