I have a extremely fat pony and I'm at a loss at what else I can do. She is a 6 year old 14.1 hh qh and weighs a little over 950 pounds (now wearing a size 50 girth). She gets worked every day, is in a grassless paddock, and is currently on two handfuls of feed twice a day along with her electrolytes. Because of her size she has developed a sore back, again. I have no idea what else I can do, any suggestions?
Oh, I tried using a grazing muzzle last year but she got so upset she foundered.
