The Jack Russell Terrier traces back to the Reverend John Russell, a Devon hunting parson who wanted white terriers with the stamina to run with hounds and the nerve to 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 strong prey drive and a talent for digging and escaping. In Cedar Rapids, a secure fence and a sturdy leash matter more than square footage. They suit active people who enjoy training, and daily exercise and mental work keep a clever terrier out of trouble.
