Welcome to Yorkie Talk. I hope that you find the help you want. To be honest, our female was still pottying in the house occasionally when she was one year old. It was very frustrating. What we found to work was to keep her on a leash when she was out of her kennel. We always had her tethered to us. As I have said before, my brother in-law once asked if she would ever get off the leash. It took some time. The leash allowed us to catch her doing naughty things and stop them. Unfortunately some Yorkies are hard to potty train. Hang in there, it will happen, but you have to be on your toes all the time. Also, the crate is very helpful in not allowing your little guy to have too much space. Too much freedom gives them the opportunity to get into trouble.
