I just started reading this thread. Has anyone here seen this laser thing or the adequan shots used on intervertebral disc disease with success? Chelsy doesn't really have osteoarthritis in her back, she has degenerative disc problems. Her one leg knuckles under her when she walks, but when I lay her on her back and force her to kick against my hands, she can do it. She just can't get the leg under herself and lift herself up with it. I think it is a nerve problem. She was pararalyzed at three years and they fused several of the discs in her lower back at the time.
I have been trying rimadyl on her and at first it seemed to help but now it does nothing at all. Right now we are walking her a bit more and I am manipulating her legs and making her kick my hands while she lays on her back. If the laser or adequan might help, I'll look for a vet who does that in my area.
