We have had our dog since he was 2 months old. We’ve worked on potty training since the beginning, but he still can not figure it out. It seems like we have tried everything (bells,clicker,punishment, rewards). He goes potty when we take him out every few hours, so he knows he is supposed to go outside, but he can’t figure out how to tell us. He accidents are about every few days. Please help us we are beginning to become frustrated with our dog.
