So we are putting in an arena and I want to build my trust with my horse. What are some exercises/groundwork to build our trust? This arena is kinda small, well really small I think, compared to the one I ride at the trainers. It’s 50 by 100 feet there will be a fence around it and standard sand. Don’t now if any of that information helps but I am just trying to get all the details out. My horse is 14.3 for size.
