The Jack Russell Terrier is named for Reverend John Russell, a nineteenth-century Devon parson who wanted white terriers that could keep up with hounds and bolt foxes from their dens. Today's dogs are compact and mostly white, about 10 to 15 inches tall and 13 to 18 pounds, with black or tan markings and smooth, broken or rough coats. The taller show type is registered in the US as the Parson Russell Terrier.
Many Jack Russells are bold, clever and funny, with a big prey drive and a talent for digging and climbing out of yards. In Wake Forest, where parks and greenways hold deer, foxes and coyotes, that drive matters on every walk. They suit active people who enjoy training, though dogs vary. Many end up in shelters because their energy was underestimated.
