Who wrote about glucosamine for dogs?

Perhaps one of you remembers a beader who recently wrote about glucosamine and another powdered dog suppliment which she has been giving her dog with great results.  Just after I saw that post, I noticed my little one, Coltrane, starting to show signs of arthritis.  For the life of me I can't locate that blog post.  Maybe you can point me in the right direction.
