Some say our newest, toughest toy for dogs has muscles. With three chew lobes, this extra durable toy rocks and rolls to keep dogs engaged. Tested for toughness, Rumpus also bounces on land and floats in water making it great for interactive play. Made from the same extremely durable material as West Paw’s other Zogoflex chew toys, Rumpus is meant for dogs who have the need to gnaw.
