My Lulu was just diagnosed with Grade 3 luxating patella. I got a second opinion as well. For now we are trying 2 weeks of crate rest with Metacam. We are also doing Glucosamine & Omega 3 supplements. Vet said those are good for every dog, especially those with joint problems. We have an appointment this Friday for our 2 week follow up evaluation. I am a nervous wreck. I am pretty sure that we will end up having to do surgery for Lulu. Fortunately, my new vet has a great relationship with a board certified surgeon with whom we have been discussing our situation. So I feel that Lulu will receive the best care. (But that doesn't make me feel any less worried)
I would definitely inquire about the Glucosamine & Omega 3 supplements. Good luck with your decision. I know exactly what you are going through & I know there are many her at YT who can relate as well.
