I get asked all the time, “Why does my horse buck?”
The short answer to that question is, “Your horse bucks because he’s trying to tell you that something is wrong.”
Bucking, like running, is your horse’s way of communicating with you. It is usually part of his fight-or-flight reflex.
But answering the question of why a specific horse bucks is a little more complicated because not every horse bucks for the same reasons.
“Something wrong” can run the gamut from physical ailments to the mental/emotional stress of an ill-fitting career or poor living conditions.
