I'm so glad to hear that Bo is now home. Ziggy sure can relate to this because she also hated being in the hospital and was so happy to be home. Hopefully you'll be able to find out what's causing her problem and that it's easily treatable.
I remember seeing you give her nose drops and I couldn't believe that she allowed you to do this. I could tell that you have a very strong bond with her. Lots more prayers and positive thoughts are being sent her way. Please continue to keep us updated about her.
