I had a lady email me with a problem this past week. Her horse gives her a little trouble whenever she tries to leave the arena and ride outside. I have worked with her and her horse so know of the problem. The owner has done a really good job, given her experience, but the horse is going to need some more work and she knows it. Someone close to her told her that if she would put a bit in the horse's mouth it would make all the difference. She asked me what I thought of that idea. I have never seen a bigger bit make any difference. Now don't get me wrong, you can put a bigger bit in a horses mouth and get a different result then you have gotten in the past, but you will do nothing to fix the horses problem. If you can't get your horse to turn right or left, or get your horse to stop with just a halter, you have a lot more trouble on your hands then you can fix with a bit.
A bit is designed to communicate with your horse, not hurt your horse. That's why most horseman will start their horse in a halter, side pull or a smooth snaffle bit. These tools are used to teach a horse. As your horse develops, over time, you may want to enhance your communication with him. THIS TAKES TIME and most people are not willing to take the time it takes. But it's worth it.
So if you are thinking that a bigger bit is the answer, think again. I once had a great horseman say, when asked about a bigger bit, "what you need son is a BIT more knowledge". I still believe this, and if a person is willing to put in the time and find someone to teach them how to acquire that knowledge you will be way ahead of the most of the horse owning population.
Will try and keep you updated with info on what the heck I'm doing with horses and music.
