He is a fearless, not to mention tenacious, hunting terrier, bred to go to ground for work and loves to dig. Intelligent, outgoing and active, the Jack Russell Terrier thrives on having a job to do to channel his energy and is best suited for a home environment with a fenced yard where plenty of engaging activity and affection can be given. The breed isn’t highly recommended for a home with toddlers, or other dogs or pets for that matter, due to his independence and lack of patience, but does well with older children. Upkeep All that energy has to be burned somehow! Because of his high energy, strong hunting drive and overall zest for life, the No. 1 concern in caring for a Jack Russell Terrier is ensuring he gets ample exercise. His activity should take place on a leash or in a fenced yard to help resist his urge to run off on a prey chase. His short coat, which can be either smooth or broken (rough), requires minimal grooming — regular brushing and the occasional bath is typically all it takes.

There were two strains of the Russell Terrier: the Jack and the Parson. The Jack Russell Terrier was smaller with a longer body and shorter legs as opposed to the Parson Russell Terrier and was used to hunt vermin and bolt rabbits. Today, the Jack Russell Terrier and Parson Russell Terrier are essentially the same breed, with the former being recognized by the United Kennel Club since 2001 and the latter recognized by the American Kennel Club in 1997.
