Well we didn't get home until around 7 pm(we left at 9 this morning ). Lots of waiting, but I understand why...lots of dogs there.
They did blood work and x-rays and said she wasn't a good canidate for the knee replacement so they are doing the TIBIAL PLATEAU LEVELING OSTEOTOMY or TPLO (middle of the page) The surgeon said it would be a much better surgery for her. They'll be putting a steel plate in her leg with 6 screws.
We left her there and they are doing the surgery tomorrow morning. They've already called and told me she had dinner, pottied and is resting fine and not stressed out (that's my good girl!). They will be calling me before and after the surgery to let me know how things are going. This place really seems to care a lot about the animals. I know our girl is in good hands

Please continue to keep her in your thoughts and I'll update when I get more info.
