Put away your shovel because these digging dynamos have your back. Jack Russells are small dogs with big attitudes, and energy to spare. They were originally bred for active work and digging is their number one absolute favourite pastime. If left without a full-time job (like hunting vermin or competing in organized canine activities), these tenacious little terriers will excavate your living room looking for something else to do. Barking to the beat of their own drummer, fearless and friendly, Jack Russells have a super-sized personality and charm to spare.
