Little story of my own , I bought a 8 year old quarter horse stallion once, completley green, no manners and was just turned out with the mares.Jet deck breeding (jet deck on his papers).Well, he bent and broke the fence panels in his enclosure, so after repairs daily I would work with him.Just keeping his attention with mares nearby was a trial , but I stuck to my plan.slow and easy, but rigid.If you wanted a fight, he would.I chose not to.You know he eventually softened , still never turned my back on him.Eventually, he turned into an saddle horse, what I liked most is the intelligence and bravery of him.For a couple years used him hunting, he travelled like he owned the mountain, stand tied for hours by himself when I was a foot..often returning many hours later..he seemed unbothered by man or beast.Eventually , I altered him, had enough colts and now a neighbor has him, a lady.
