The next time your dog needs to go, she’ll let you know with Caldwell's Potty Bells Original Dog Doorbell. As an alternative to barking or scratching at the door, the gentle jingle of Potty Bells is a much more pleasant signal that it’s time for a walk. Training your pup to tap the bell when nature calls is simple with the included three-step e-guide. She’ll be ringing them in no time, and she might even start to use them on her own by association. The snap closure makes it easy to hang Potty Bells from any doorknob, lever or handle. Charming yet durable, they’re designed with reinforced nylon stitching, six nickel-plated bells and a reversible alloy ornament with “I heart my dog” on one side and “Potty Bells” on the other. It’s a stress-free and less noisy way to potty train.
