1. Hang the loop of the Bells on the inside doorknob of the door that your dog typically exits the house. Choose wisely as you do not want to move the bells after training has started.
2. Every time you take your pup/dog outside to potty, state a simple command phrase, I use "Go Potty" or "Outside". All members of your household should be consistent and use the same wording and actions with your pup/dog.
3. After stating your command phrase, immediately ring your Bells in front of the dog.
4. After ringing the bells and saying your command, allow your dog to go outside. When they have done their "Business" reward them with verbal praise and a pat or stroke. DO THIS EACH TIME YOUR DOG IS TO GO OUTSIDE AS CONSISTENCY IS KEY!
Training Tip: I suggest that you not use potty time to play with your dog outside so they don't associate ring time with playtime. You can always take your pup outside to play at other times when you choose to. The pup/dog will eventually associate ringing the bells with going and the praise they receive from their favorite person, you, is reward enough!
I certainly hope this helps someone out, as I have successfully trained several puppies to use the doggie door bells. Below is a link to the Poochie-Bells on Amazon.
