rpfix , welcome to YorkieTalk! Sorry to hear about your little boy's knee problem. I know it's tough knowing this going in ... I think, since it's a trait of these little ones, that it's a fear that all yorkie lovers live with. We have had no experience with this, only all the information that we have read. We will certainly remember this little guy in our prayers, I know this is a tough decision for you. Please keep up updated.
