The Jack Russell Terrier was bred more for companionship, instead of strictly a working dog, so they are a milder in temperament, but are not recognized as a registered purebred. However, the Parson and Russell Terriers are from working lines, and are recognized as registered purebreds. NOTE: Jack Russell Terriers, Parson Terriers and Russell Terriers are all very closely related and very similar.
