Great article! So nice to see that it encourages soft forgiving hands, proper bit selection, and most importantly, PATIENCE! I've been working on my OTTB's "headset" for a long time. He always carried it up in the air. Finally the other day he figured out what I wanted, dropped it down and relaxed! What a huge accomplishment! I believe that too many people are impatient and use draw reins as a crutch.
Transitions are great, but they have to be done properly. By getting the horse to lift his/her shoulders, he/she can carry themselves. A horse who is avoiding the bit has no self carriage. Once a horse is lifting and moving the shoulders, then the head will come down and the proper muscles will build. By NOT having contact on the bit the horse has to carry themselves and doesn't rely on their crutch to support them (YOU!).
I really like this article~ I have a horse with this problem. He holds his head high in the air and it is hard to use the right aids and paterns of aids to get him to sofen up and put his head down to loosen the martengailes hold on his head. When he actually does soften up and I give him some slack as a reward, as soon as I do anything else like direct him or try to go on a circle he automaticly tenses up and puts his head high in the air and I have to go all the way back to step one! I shall try some of the tips and see if I can get him to soften up a little more. Thank you for the help~
