She has been on glucosamine with chondroitin for 3 years (900 twice/day) and it helps, but lately it has been much worse. I will look into msm too.
I don't walk her at all anymore because it looks so painful, but I can easily start her walking daily as I am a stay at home mom.
We put her on medicam for the pain but it didn't help, I will ask my vet about those injections. Thanks for the advice!
