My Yorkie is 6 months old and when we got him a month ago, he was trained to go potty outside or on his potty pad. I had him neutered last Friday and ever since he has been going to the bathroom everywhere, but the potty pad. What is going on!!!!???? He was doing so well and I was praising him...now it's like he is doing the opposite. Has this happened to anyone else, where it's lilke starting over. We only had him two weeks and then my husband deployed to Iraq. I don't know if that makes a difference or not, but he hasn't been himself for the last week and it's a rare occurence when he goes on his pad. What do I do??????? I'm here by myself with him now and am so upset with this digression. Help!!!
