I have to agree with jmdt.
You have to love them and enjoy them everyday.
Be aware of their actions and body language but don't look for trouble.
I have had 3 Yorkies and they were really very healthy.
Sure, Yorkies are more prone to certain things but I really don't think of them and just enjoy my little one always. I hope that doesn't sound like I don't care because I really do. I just choose not to dwell on what
could happen.
So please try to relax and enjoy your little one.
