Simply add your dog's favorite treats (sold separately) to the zipped compartment to encourage them to chase and retrieve—but remember, he only gets the treats after he brings the toy back to you! The Coachi Fetch & Reward is brilliant for teaching new dogs how to fetch and retrieve. Plus, the added rope makes it easier to nail those long-distance throws! The Coachi range is designed to focus on effective, humane and positive training methods, making training simple and rewarding for both owners and their dogs.
