First of all welcome to YT!

And secondly I am so sorry to hear about your little Peanut

And not that it is good news by ANY means that he hurt his poor little leg, but at least it wasn't something
worse 
I have heard HORROR stories about Yorkies jumping off couches...that is why I get so freaked out every time my little Stedman does it, and he does it ALL the time!! I can't get him to stop. I have tried everything. He is like a little acrobat!
I will be thinking about your baby...and please let us know how he does after the surgery! He will be in my thoughts and Prayers
