These Dog Door Bells are a great way for your dog to let you know that he needs to go outside. The extra large bells can be heard from afar and are double-walled for durability. They work on any doorknob and hang low enough for any pup to reach.
I trained all 3 of my dogs to ring the doorbells when they need to go potty. It’s a great way to help keep the house accident-free. Here is a video on how to do that.
