The question came up recently, would I teach a horse first aid class? Not being qualified to do this, I declined. But here are some videos from experts that show you handy procedures, so you can be ready when the emergency happens. Trust me, it will. P.S. Make reading glasses part of your first aid kit. Not everybody can read that fine print.
