I have to say, that I have never used a bell, and Teddie, 1 yr old, does me the same way. She will come in from outside potting, and I will sit down and she will run back to the door, like she has to pottie again. I don't think it has any thing to do with the bell or what ever your using, I think these dogs are just smart and like to go outside and play. Teddie loves it outside. I do want to try the bell thing though. It isn't like she is 100% house trained any way, so what do I have to loose?
