I think, with the bell, the dog is training you.

Does your dog have potty accidents in the house? The most crucial part of housebreaking is teaching your pooch how to alert you when he needs to go out for a potty break. Training your dog to ring the potty alarm using a bell is an effective house training method.

Once the dog understands the concept, bell training solves a couple problems:

DIY Doggy Potty Bells: 1 spool of ribbon, 1 package key rings, 1 package jingle bells and a sewing machine. Takes less than 10 minutes and costs less than $10! #puppy potty training

Type: Training Dog Bell Color: Multi

“Pebble Smart Doggie Doorbell is so much easier to train with than other types of doorbells.” Purchase a dog door bell or make your own with a couple of sleigh bells from a crafts supply store. Attach some kind of sturdy string to the bells. (You’ll use the string later to hang the bells on a door knob or on a hook next to your door.) Before starting your first training session, cut a number of tasty that your dog loves into raisin-sized pieces. You can use soft dog treats, chicken, hot dogs, croutons or cheese.

Bell Training for Dogs: It Really Works

Every time that you go outside, hold a treat behind your bell. Your dog will hit the bell with her nose to get the treat. "Good Dog" sign, and out you go. In order for your dog to understand that this bell means "potty" and not "playtime," keep her on her leash until she finishes (use the same procedure as above for house training; stand in the spot, don't move, and wait for her to finish). Once she is done, you can take off the leash and let her play if you want, or you can bring her back inside and play at a different time (don't have her ring the bell when you go out for playtime). If she doesn't eliminate within a couple minutes (try using your signal, if you have taught it), bring her back in, no play time (period).

Training Your Dog to Ring a Bell to Go Out to Potty - Pet Expertise

This training is not just for puppies. Older dogs can learn too. You can successfully train an older dog to ring the bell. Who says you can't teach an old dog new tricks. I taught my 5 year old rescue dog in a matter of days. Good luck with your door bell training. One thing to remember is be consistent and do it every single time your dog or puppy goes out to potty.
