Bunting is most commonly referred to in domesticated cats, but it happens in horses too. Some horse professionals may use the word to describe any horse behavior in which a horse bumps or "bunts" something or someone. Bunting, however, is different than the movement of the head designed to scratch an itch, as described in this article. You'll notice bunting if the movement of your horse's head tends to have a "fling" or a "bump" when it comes in contact with your body. A horse's attempt to scratch an itch on you will be slower and more insistent compared to bunting type movement.
