Hugging the Pole
This is a great annoyance to the other horse, and he will probably learn to do the same thing, not from imitation, but from leaning inwards, so as to enable him to stand against the other horse, leaning upon him. This habit may be broken up by securing a piece of sole leather to the pole upon the side where the animal leans, having a number of tacks driven through it in such a manner as to protrude from the leather towards the horse.
