Would this be okay to give my dog?

A dog the size of yours, if she's having trouble and is really stiff, needs 1000 mg daily of glucosamine chondroitin with MSM. In fact, my vet told me to start my 70 pound dogs on 1500 mg for the first couple of weeks. I don't think this Joint Enhancer stuff is nearly as good as buying glucosamine chondroitin with MSM - it comes in chewable tablets and liquid.
