My problem is with my 20 year old SA Boerperd Gelding. I bought him about five years ago off a lady whose daughter used him mainly for short distance endurance and mounted games. When they weren't riding him he was used as a cow pony by the workers. I use him mainly for trail riding and once on a while he gets to go gateher cows which he seems to like a lot better than trail riding. (I'm starting to look for my ideal trail horse). The thing with Hans is he hates walking on the trial. As soon as we start walking it's not long before he starts nodding his head. He just throws his nose up a little as if he wants longer reins, but no matter how long I make his reins it never seems to be enough. He's fine if we're cantering or trotting. What can it be and what can I do to stop him?
