Give your dog options during fetch with Chuckit!'s Gen 3 Fetch Medley. This set of 3 premium fetch balls includes the classic Fetch Ball, the popular Ultra Ball, and the Rugged Ball. The classic Fetch Ball features a high bounce when thrown, which helps keep dogs engaged in play. The Ultra Ball is designed to have high buoyancy and durability for land or water play. The new Rugged Ball has unique ridges that make it easy to grab and help keep teeth clean. Each medium ball has a 2.5-inch diameter and can be used with any medium Chuckit! ball launcher. Dog balls should always be small enough for your pet to carry but large enough that the ball cannot completely fit in their mouth. When in doubt, buy a size up. While each ball is soft on your dog's mouth, they are not intended as a chew toy or for aggressive chewers. No toy is truly indestructible. Always supervise your pet during play.
