I spent many many years working with horses that had different amounts of anxiety and fear, never understanding what a fear threshold was and why it mattered. In fact I think the majority of horse people out there can't tell you what a fear threshold is. Fast forward to now and I honestly have no idea how I ever got away with not understanding this concept. I believe this bit of information is so critical to successfully and humanely training and handling a horse that it should absolutely be information that every horse person understands. Whether you are a trainer, a horse owner, or just taking occasional lessons you should be able to recognize fear levels in your horse and know how to handle them. It's absolutely vital for the well-being of your horse, the success of your training program, and your own personal safety.
