I don't have any knowledge to help you with but I too wanted to pass along good wishes and add her to my prayer list. I hope you have a good orthopedic specialist. I think these days vets are like docs -- you have to see a specialist to get the most up-to-date, state-of-the--art care. Medicine has made so many advancements, hard for any one doc to stay on top of all areas. So, specialists really have a place. Sounds like this little gal needs one for sure. Between the specialist and your love -- she should have a better chance at developing as she should.
