Dog tennis balls don’t get much better than this. The Chuckit tennis ball for dogs is a tennis ball but better, designed especially for dogs. These are high visability two-tone with extra wall thickness. Chuckit balls are designed for the most demanding use. Not just any old tennis ball will do. This has been designed especially for dogs with an extra thick rubber core and attractive colours for improved visibility. Especially for dogs but still with that tennis ball charm.
