JW's® Hol-ee Bottle Dog Chew Toy features the same non-toxic, durable, super-stretchy design as the original Hol-ee Roller®, but is stuffed with a replaceable plastic water bottle for added fun. As your dog chews and the water bottle gets crushed, the Hol-ee Bottle design allows you to replace the used water bottle with a new water bottle to keep playtime going. If you've run out of water bottles, the open design allows pet parents to stuff the Hol-ee Bottle with treats. Works great as a chew and fetch toy. Comes with its own plastic water bottle inside to get the party started.
