I'm thinking about having stem cell therapy on Lightning to help with his hind end weakness. I know a lab that had it done and the difference was astounding. A new laboratory that processes stem cells has opened very near where I live (I think the only other one is in Calif.), and given all the horse business they get from the racing industry, I'm hoping the cost will be relatively reasonable. Has anyone tried this on a pet or know of someone who has? Lightning's issues are purely age-related. He's 13, and in excellent health otherwise (if you don't count his bad eye). And they would be his own stem cells, so there's no threat of rejection.
