I see the post about the chain over his nose. I agree. I have used it before, yes it sounds mean and nasty but it isn't. It gives you the little bit of leverage you may need with him at first. I have an Arabian and Quarter horse stallion that I have never touched with a chain but a gelding that has had one. It is based on how the horse was raised. The gelding does no longer use a chain, it was a matter of days with it literally. Good luck, I agree give it some time and if it doesn't work it may be time for something different. But do it when you know you have given your all and that you are ready to say ok. Only then will you feel right on giving up.
