I've been writing in the forum about rescuing a horse named Joe. To keep this short, the vet believes that Joe had a fractured bone somewhere between his fetlock and his pastern that was left untreated. Now he has a constantly swollen fetlock and limps slightly. The vet recommended a powder joint supplement with glucosomine, msm, etc. My farrier came out and recommended injectible Glucosomine. What are some thoughts on this?? Farrier says it will cost $60 for 100 units. He said you would give a bolus for the first two weeks to give him a boost of meds and then level off to 10 units a month. I needs opinions on this and other ideas how I can help this guy. He deserves the most that can be done he's surely endured more than his share of pain and neglect.
