I gave up with the bells. When I started to train her with this she would go to the door and ask to go out. When I started to ring the bells, she was afraid and wouldn't go to the door at all and started to potty on the floor again. When I took the bells down, she went back to asking to go outside. The bells are gone for now, I will just have to keep an eye on her. She has gone 2 days now with no mistakes. YEAH Bella!!!!!!
