Start by rewarding your dog each time they touch the bells, then progress to letting them out for playtime or a potty break as needed. The adjustable design is paw-fect for dogs of all sizes. Simply hang them from a door or hook at your dog’s head height. In no time, your smart pup will catch on, preventing indoor accidents and nuisance scratching at walls or doors. 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.
