I have a 9 month old QH colt. When we feed him grain he gets so excited he pounds his front feet on the ground so hard he makes a trench in the ground. I have tried standing there and pushing his knee down and saying "no", but this only works for a while. I read once in my Beery books that we should tie a small board to his leg and when he stomps the board hits his knee and stops him. Have not tried this theory yet. Any other ideas? He does listen well, and trained easily to lead and tie.
