The Coachi Two-Tone Dog Whistle is the perfect all-round whistle for the whole family. This whistle produces two distinct and clear tones, allowing you to train different commands or train two dogs at once! Whistles are great for recall training, as they help to standardize commands between paw-rents, children, trainers and more. The light, compact design can easily be slipped into a pocket or bag to ensure you always have it handy. Plus, it comes with an adjustable lanyard for easy wear on your wrist or neck. 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.
