Hi Everyone,
Thank you very much for your words of encouragement and advice. Just like last time she pulled a muscle when playing and that is why she was acting strange all of the sudden. She had me very worried for a while because the one day she just layed around, didn't want anyone around her (very unusual) and seemed sad (She also ate very little). She pulled the same muscle about a year ago. This is my first Yorkie and they seem to be very delicate and almost people like when they injure themselves. All is well again though, she is eating and playing!
Thanks again for all your help
Tiffy and Judy
