Mine has done perfectly well with the hanging bells. I'm so grateful for those things! She makes them ring with her nose, which is the correct way to teach them, but I understand how difficult it can be to get them to use their noses instead of their paws!
I could literally get down on my knees and thank heaven for them everyday. She hasn't had an accident, except right after she was spayed at around 6 months of age. She will not go in the house. I have them hanging on the door going to the patio and the door going into the attached garage. The garage is where we have piddle pads and she goes in there at night and in bad weather.
