Air Dog toys are just like pure tennis balls. They are made with the same materials, by the same manufacturing process. Everything that made the tennis ball our most popular toy is built into Air Dog Toys. The only difference is that our toys never bounce the same way twice. Great for: Fetch and retrieval Erratic Wacky bounce They float so take them to the beach Brightly colored so they are easy to find in the snow. Pressureless.
