The Jack Russell Terrier is a type or
landrace of small, principally white-bodied, smooth or rough-coated
terrier that has its origins in
fox hunting. The name "Jack Russell" has been used to describe a wide array of small white terriers, but is now most commonly used to describe a working terrier.The Jack Russell Terrier is not the same as a
Parson Russell Terrier, which is a breed recently created by narrowing the Jack Russell standard. The Parson Russell Terrier is primarily a show dog, and is rarely found in the hunt field.The Jack Russell Terrier is also not the same thing as an
Australian Jack Russell Terrier or
Russell Terrier, which are dogs first brought into the
Federation Cynologique Internationale (FCI) in 2000 and the
United Kennel Club in 2001, and which are maintained under a different breed standard and described as having been developed in Australia out of dogs originating in
England.

TerriersOverview
Jack Russells make very enjoyable companions when raised in the right setting--roomy suburban or country areas. They were bred as runners and are not suited for city or apartment life. Because they retain their working instincts and may chase and kill cats, rabbits, and other small animals, they should always be leashed or exercised in a secured area. Obedience training must start early because these dogs are easily distracted by surrounding activities and scents. They enjoy children and other dogs if exposed to them at an early age. They will bark when someone comes to the door but are not usually aggressive. They can, however, be protective of their property--toys and food bowls and such.
