Review on 🔔 Upgraded Dog Doorbells for Potty Training and Going Outside - Premium Quality Puppy Bells for Dog Lovers - 3 Snap Length Adjustment - Suitable for Cats and Dogs by Esther Fisher

These Calls Really Work! No more incidents at the door. My daughter taught her puppy how to use puppy bells and was amazed at how well they work. I was skeptical but looked them up on Revain and decided to give it a try. We have two dogs. seven-year-old MinPing and a Cockapoo pup. They are both house dogs. MingPing has learned to warn us when he has to go out. Our dog has never learned to tell us that she has to go outside. I hung Puppy Bells on the patio door and followed a basic dog training routine to show the behavior and reward the dogs when they mimic the behavior. It took both dogs less than a day to learn to ring the bells when they needed to go outside. No more accidents at the back door. The bells are loud enough to be heard throughout the house but not so loud as to be intrusive. The strap is strong. Don't worry about wear and tear. The strap is long enough to reach from the patio door handle up to 6 inches off the ground. Ideal for dogs of all sizes. We are very happy with this purchase. Five stars.
