Wow, Suz, here we go again with our weird parallel lives. Abby, my Shih Tzu, had a horrible time with being spayed. She laid around and would hardly try to walk because it hurt so much. It broke my heart.
Then, when she was about two years old, the vet recommended knee surgery on both of her back legs. I mentioned to the vet what a hard time Abby had with the spaying operation and she said that this operation would be much more painful than that one. So, I talked to two other vets to get their opinion and each differed on whether it was a necessary operation. I decided against having it done.
So far she is almost ten and having no problems with her back legs. After hearing your story, I'm glad that I decided against putting her in that kind of pain.
It hurts to see an animal in pain ~ specially one that is part of the family.
Lisa, I hope that you pup is up and around quickly.
