I made my own but they are the same concept. I don't think it is too late. Loki only goes outside, we don't do pads. Loki learned how to ring the bell in a day or two and now he rings it when he needs to go out. He's pretty good about ringing it only when he needs to go, not just when he wants to go out and play, since he goes outside on a leash. We haven't had any accidents since we started using the bells months ago. |
