How do you get a horses head down?

Well it is a process. If you know where the Poll is.....(Between the ears) lets say you are traying to put your halter on the horse. Put your right hand between the horses ears and put pressure....if you horses does not put it head down a little then put more pressure....and so on and so forth....now this is a process so don't expect huge results at first. if your horse puts its head down even a little then take your hand off right away and give your horse a pet. hope that maes sincel.
