The Jack Russell Terrier is named for the Rev. John Russell, a nineteenth-century hunting parson in Devon, England, who wanted white terriers that could keep up with hounds and bolt foxes from their dens. Today's Jack Russells are compact, mostly white dogs about 10 to 15 inches tall, with black or tan markings and smooth, broken or rough coats. The taller show type is registered in the United States as the Parson Russell Terrier.
Many Jack Russells are bold, clever and funny, with a strong prey drive and a talent for digging and climbing. In Chattanooga, where wooded lots and creek trails are never far away, that drive finds plenty of triggers. They do best with owners who enjoy training and outdoor time and who set firm, positive boundaries. Dogs vary, so a Jack's history and energy matter more than the label.
