Aw, poor little Missy. We are pulling for her. She really had been through the mill. It's not fair that she has to go through all of this. Hopefully she will be "good as new". Then she can just be a dog and play all day, if she wants. Give her great big get well hugs from Coco, Pebbles and Trixie.
Saying a little prayer for her and you. Stay strong, she needs her mommy!! Bless you and little Missy. Please keep us updated.
