It's not that they don't work, it's just that there haven't been a lot of major studies done on it. Conclusive controlled studies are the only things most medical/veterinary professionals will refer to as "evidence," I think. Antecdotal evidence, no matter how compelling, isn't going to get the same level of respect from medical professionals, and rightly so. That said, I think a lot of doctors and vets don't pay ENOUGH attention to antecdotal evidence, especially with supplements that haven't been proven or disproven one way or the other. A rare few will also try to talk you out of any effective treatment that doesn't make them money. I think that type of greedy bastard is outnumbered by the vets who care more about the animal than the money, but they are out there.
I've had two dogs respond amazingly well to glucosamine and condroitin supplements, one with spondylosis and the other with luxating patellae. My own knee doesn't seem to respond at all, but I think my problems are mainly muscular at this point, so that doesn't disprove anything to me.
