The JW® Hol-ee Roller® X extreme dog toy is a unique, thick natural rubber ball for dogs. It's tougher and thicker than our traditional Hol-ee Roller. Designed for tough dogs and tough chewers. The Hol-ee Roller X has strategic patented honeycomb cutouts covering the ball so a dog can grab it and pick it up. It's also great for games of tug-of-war! The cut-outs can also be easily filled with a pet's favorite treats or small toys for long-lasting boredom-busting fun! All JW pet products are intelligently designed with our commitment to a fun first while providing quality, non-toxic toys for pets. Ships in random fun assorted colors.
