The males have a serious issue with peeing so do Yorkies. My x wife thought she was going to bread Yorkies. We had over 10 of them running all over the house. The girls loved it, me not so much. There was piss and shit everywhere. When we put in new carpet they were outside dogs. My pug is not an inside dog either. I can't stand peeing on the floor. Even when my kids do it I still get mad!
