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 crinkly crunchy 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. This toy works great as a chew, fetch, and enrichment toy. Try filling the water bottle with treats and cut holes in the plastic bottle so the treats will escape as your dog rolls the toy around for a fun brain game! This toy comes with it's own plastic water bottle inside to get the party started.
