Get Ready, Set, Fetch with the Chuckit! Whistler Dog Fetch Toy. Designed to keep your dog interested and engaged in fetch, these high-bouncing rubber balls feature four holes that produce a whistling sound as they soar through the air, providing your dog with something to chase.

Made from durable, easy-to-clean rubber, the Whistler is gentle on your dog’s mouth when retrieving the ball. It is compatible with Chuckit! Launchers and is available in a variety of sizes for all dog breeds.
