Even though it seems as if your horse explodes out of nothing and has gone from a pressure level of 2 to 10 in a split second, there’s often something else going on. Very often, the pressure has been slowly building up in your horse through his posture.
Tension builds up in the body as a means of protecting himself. A tension or posture gives a heightened state of alertness or readiness to flee. When the pressure or threat in the environment becomes higher than the horse coping level, it’s then that the explosion comes.
Some horses can become almost comfortable in this heightened state or readiness in their body through a feeling that they are protecting themselves to a certain level and therefore seem relaxed and normal while under there’s a pressure level barrier.
Often the biggest contributor to this pressure barrier being created is desensitizing where the horse becomes desensitive or numb, ignoring the pressure in his surroundings up to the level he was desensitized to or gotten used to. Everything will be fine until the pressure in the environment passes that level.
It can be difficult to notice that building up of pressure when riding. Because it’s not easy to ask all the right questions in a safe position from the saddle, we go to the groundwork. On the ground you can see more clearly all the signs from the horse.
If he is acknowledging all the questions being asked of him and making good, positive decisions in the reactions in his body. Or if he is mentally going to another place in the back of his mind, ignoring or blocking out the pressures in his surrounding.
