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.
