I hope the PT does you good Leslie...I had 35 sessions in order to avoid surgery on my leg! Kind of extreme, but less trauma then getting cut and "rebuilt". I hope Squirt stabilizes and is comfortable, for whatever time she has has left to enjoy with you. I know exactly what you are feeling...you want to stay right by their side and it hurts to leave them alone. When my first Aussie had Cushings so many years ago, we had to isolate her in the kitchen...just too many accidents. The poor girl cried and cried. It broke our hearts..so out came the air mattress and I slept with her in the basement during those last few weeks. It's tough, I know.
I've had a lot of ups and downs over the last year...my Mom passed away exactly one year ago today. That really threw me "off" for several months. Even the dogs were wondering "what happened to Grandma"? Eh, such is life. Mom loved all of the dogs over the years, even though it eventually became impossible for her to give them the kind of attention she would have liked (due to parkinsons disease). So, enjoy them while you can...lots of hugs and kisses!
Be well.
