Jack Russell Terrier
Trait scores are tendency indicators from 0-100. Example: 42% alone tolerance roughly maps to around 4 hours alone.
Jack Russell Terriers are compact, fearless fox hunters with inexhaustible energy and a stubborn streak. Bred by an English parson to bolt foxes from dens, these are intense, intelligent working terriers who need vigorous exercise and mental challenges, and their tendency to dig, bark, chase, and challenge other dogs makes them too much dog for many unsuspecting families.

A Day in the Life
A purposeful walk and short training game helps them settle for the day.
Most do best with another activity block before winding down near their people.
Longer outings and enrichment games noticeably improve behavior and sleep quality.
People often underestimate how quickly behavior slips when routines are inconsistent.
Exercise & Activity
Plan on around 95 minutes of daily activity split between walks and mental games. Consistency matters more than occasional long outings.

Breed History
Origin
The Jack Russell Terrier originated in United Kingdom.
Original Purpose
Jack Russell Terrier lines were developed for vermin control. That working role still shows up today in temperament, stamina, and day-to-day needs.
Breed Group: Terrier. Terriers were bred to hunt vermin. They are usually bold, energetic, and persistent.
In modern homes, this history matters because it predicts what helps the dog thrive: enough movement, clear structure, and outlets that match their original instincts.
Fun Facts
Jack Russell Terriers were developed by Reverend John Russell in England specifically to hunt foxes from their dens, and they're named after him.
The breed nearly went extinct in the 1980s when fox hunting declined, but determined breeders saved them by creating new breed standards.
Jack Russells have a prey drive so extreme they'll dig under, climb over, or chew through anything to pursue small animals—they're escape artists.
The breed has an independent streak and will refuse to obey commands if they've spotted prey, making them unsuitable for off-leash activities.
Jack Russells are prone to patella luxation (knee dislocation) and progressive retinal atrophy (PRA), requiring health screening.
