Per bouncy and crazy fun, West Paw’s dry treat-dispensing, puzzle dog toy, Rumbl, encourages healthy play. Rumbl's unique “fish trap” opening makes for easy loading yet keeps dry food inside. Doubles as a slow feeder: large fits two cups of kibble, small fits one cup. Superior durability and hollow construction make this puzzle toy’s springy material heaven to a dog’s chompers while its playful wobble adds to the excitement and increases engagement.
