The Jack Russell Terrier was developed in nineteenth-century Devon, England, by the Reverend John Russell, who wanted a small white terrier that could keep up with hounds and bolt foxes from their dens. Today's dogs are compact and mostly white, with black or tan markings and smooth, broken or rough coats, usually 10 to 15 inches tall and 13 to 18 pounds.
That working background shows up in Fishers backyards. Many Jacks are bold, clever and funny, with a strong prey drive and a talent for digging, climbing and escaping. They do best with people who enjoy training and outdoor time and can offer daily vigorous exercise, mental challenges and consistent, positive boundaries. Dogs vary, but underestimated energy is a common reason Jacks need new homes.
