We have a 3yo mini who we bough in fairly rough condition, the winter was not good to him. He is gentle as can be, but he is a little out of our realm. Obviously with a bigger horse we would ride/pony it to work it out, or we would road it behingsd the UTV. What is the best way to put one of these guys into good working shape. We just bought a harness and will be picking up a cart soon. We have essentially just kind of turned hm out and he is hanging out in the barn with our LGD but he seems very lathargic to me.
