"Tried this on my 26 year old retired world cup show jumper, a dutch warmblood, after a bout with cushings related founder. he had never been lame prior to this episode, but was getting stiff from old age. Anyhow, desperate for a quick recovery for my dear friend, I added this to his feed every morning. Within just about ten days I think I saw a general improvement and he continues to be more comfortable even after the founder was thankfully resolved. I would have started my 18 year old stallion on it already as a preventative were it not so damned expensive. It's the same price at the co-op as it is here, or I would buy it here along with the boy's pergolide. Come on smartpak, give us a deal on this fine product!"
