The Jack Russell Terrier is named for the Reverend 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 dogs are compact and mostly white, 10 to 15 inches tall, 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 strong prey drive and a talent for digging and escaping. In Midland, that means a sturdy fence, a leash outside it, and enough daily exercise that a long walk and a game of fetch are routine. Dogs vary, but plenty of Jacks end up in shelters because their energy was underestimated.
