Hugs to you. I know how scared you must be. They can scare the living daylights out of you. They just don't realize how little they are. They all seem to think they are St. Bernards!
I'm praying your little guy will make a successful recovery and be able to have a normal life. His age is in his favor.
I know you can't wait until Saturday morning, but it sounds like he is doing well in the hospital. I can imagine how happy he will be to see you. Please keep us posted. None of us ever knows if we will be in the same boat as you. They jump like nothing I ever saw before!
