My min-pin is 6 months old. when we first got her she slept in the cage so she didn't hurt herself. She went to the bathroom in the cage all the time even when she was out of it. Once we decided to leave her out of the cage she started going on the on the floor. Now she usually pee's in the cage but she is terrified to poo in there. Even when i catch her about to start and bring her to the cage and congratulate her she stops and is terrified to do it. Then i let her out and she finds another place on the floor to start. I recently bought a plastic grate like in the cage to try to get her to go on that. Any other ideas?
