Bull Terrier vs Jack Russell Terrier

Pick two breeds to see them compared side by side.
Bull Terrier
Developed in 19th century England by crossing bulldogs with terriers, this breed started out in fighting rings and rat pits before being refined into a purely companion breed. The distinctive egg shaped head, with no clear stop between forehead and muzzle, is the breed's trademark and recognizable even to people who know nothing else about dogs. A male can weigh up to 28 kilograms of muscular, compact build. The short, dense coat needs little upkeep, but underneath it sits an unusually strong bone and joint structure. The Bull Terrier is known for a stubborn, playful streak and a strong drive to chew and play that can turn destructive if the dog is bored. With consistent socialization it's typically friendly toward people but can be intolerant of other dogs of the same sex. Life expectancy runs 10 to 14 years.
Jack Russell Terrier
Like its close relative the Parson Russell Terrier, this breed comes from the same work by English clergyman John Russell in the 19th century, bred to hunt foxes alongside the hound pack and go to ground after them. Unlike the longer-legged Parson type, the Jack Russell Terrier stayed shorter and more compact, which lets it squeeze into narrower dens. An adult weighs barely 8 kilograms, with a coat that comes smooth, rough, or somewhere in between. Energy runs well beyond what the small size would suggest, and without enough outlet the dog tends to become loud and destructive. The hunting instinct remains strong, and small pets at home can be chased without any training at all. It's playful with children but needs a firm, consistent hand. Life expectancy runs 13 to 16 years.
