My EQ and Hunter horse sometimes gets excited when we start jumping, but when I try to slow him down and collect him he gets really worked up and irritated because I am in his mouth. I give him a release when he does slow down but he just speeds back up a few strides later. I had his teeth checked ride him in a happy mouth bit and he has seen the chiropractor so nothing is wrong with him. I really have no idea how to fix this problem because he can be a handful and I can't have much contact to control him because he just gets more worked up and spazzes out on me. Advice please!
