Help train your pup with the Li'l Pals Dog Potty Training Bells. This colorful training device is designed to hang on a doorknob, so your dog can jingle the bells when he needs to go outside. Not only will this help avoid accidents inside your home, it can also help prevent your pup from barking, whining and scratching your door. To help your hound get the hang of things, simply jingle the bells when you're ready to take him outside to go to the bathroom, and reward him when he begins to use the bells on his own—this helps ensure his new habit sticks! You can teach him to use his nose, paw or even his tail. It may take a few tries, but once he gets accustomed to the bells, he'll let you know when it's time to go!
