The Chuckit! fetch medley 2 is a triple pack of Chuckit! fetch balls. The medley pack includes a Chuckit! strato ball, erratic ball and an ultra squeaker ball, our classic rubber ball with a squeak. The orange strato ball bounces higher, flies farther and has more visibility than other balls. The striped ultra ball is super bouncy, buoyant and easy to clean for the best game of fetch ever. Lastly, our green erratic ball is shaped to create an erratic, random bounce to keep your dog guessing. They are all made from natural rubber that is easy and safe for your dog to grip in his mouth and they are sized just right to work for dogs from small to large.
