 If you're a veterinarian and this is important, thinks your dog is currently in pain, has some arthritis, I'd do some x-rays to see, then what I would do is consider pain relief, at least for a short period of time. And if nothing else, glucosamine chondroitin, there are some other products that can be used as well to kind of take the edge off the pain so your dog can tolerate a bit more exercise. Well, thank you very, very much.
