Built for tough chewers, West Paw’s newest and most-durable dog toy is so strong some say it has muscles. With three chew lobes, this extra-durable toy also rocks and rolls to keep dogs engaged. Tested for toughness, Rumpus bounces on land and floats in water making it great for interactive play inside or outside the house. Made from the same extremely durable material as West Paw’s other Zogoflex chew toys, Rumpus is meant for dogs who have a need to gnaw.
