When you take this approach, you will realize that we often do exactly the opposite. We often increase the level of training in that specific area to distract our horse and force our horse to go into the corner. I do have to admit that this can work for some horses. Some horses need just a little bit of encouragement and they will be fine once they have gone past it a few times.
However, this approach often doesn’t work with more sensitive horses. So, if a problem with a certain scary corner or object keeps coming back, you know that forcing your horse will not help and perhaps make it even worse.
You’re basically adding pressure to a situation where he already feels a lot of pressure. Your horse’s association with the corner becomes only worse, because not only is it life-threatening, as a rider you also add pressure with your leg and perhaps also with the rein.
Secondly, we can also give our horse the wrong signal when we badly time our aids. Imagine that you walk up to the scary corner, or something else that your horse is afraid of, and you feel that your horse gets more uncomfortable and tense. He starts to slow down and hesitates to go forward. Just as he wants to take a small step forward, you give the leg aid to convince your horse a bit more. To give him that extra push to go forward.
Big mistake! You just ‘punished’ your horse for giving the right response. He stepped forward and you gave pressure, while you should have released pressure and not do anything at all.
A third approach we often take, is not letting our horse see the scary corner by bending his neck to one side or taking your horse shoulder-in. In my opinion, this is just a temporary fix and doesn’t solve the underlying problem. Often, the next time your horse sees the corner again, he will spook again.
