The Jack Russell Terrier, the tenacious and aggressive fox hunter was created by John Russell, a fox hunting enthusiast from Devonshire in England. He developed a strain of Fox Terriers to suit his needs for a dog to run with his foxhounds and go to ground to bolt the fox and other quarry from their dens.
Two varieties evolved with basically similar standards except for differences, mainly in height and proportions. The taller, more squarely built dog is now known as the Parson Russell Terrier and the shorter, slightly longer proportioned dog, is known as the Jack Russell Terrier.
Intelligent, cheerful, playful, the JRT is first and foremost a working dog with very strong hunting instincts.
