we have glycoflex for Avie. then we started trying K9 liquid health (glucosamine & ha) (it is liquid.. we put it on her food-she loves the taste of it!) we haven't been using it long enough to see results.. but hope it works!
we are interested in cosequin, as well!
we were going to get this.. then i ended up picking some of the liquid health at our feed store! if it doesn't work-we will be ordering the cosequin! would love to hear more feedback!
