Arem, When you know how to properly bit a horse, the horse accepts the bit. You never hear any professional trainer expounding on how it's impossible to train some horses to wear a bit. Where you see that is in non-professional attempting to train it, then when they can't get it done, because the horse can read how to get that person to quit fooling with them, they declare : "My horse doesn't like..............." That's blaming the horse for the human's failure to be capable of training it. I got this lesson years ago. I was 15. I had a girl come in wanted to work and take out rides. I could not teach her to sweep a floor, the shavings would just be scattered to the walls and the middle of the aisle would be clean. Didn't matter how many times I showed her. I could not teach her to bridle a horse, her hand would end up in the horse's mouth and her standing in front of the horse every time. Didn't matter how many times I showed her; I Could not get through to her. It's not that you have a special horse that won't accept a bit. I don't care if a person wants to ride in a halter. Doesn't bother me. If you can't successfully bit the horse, though, don't blame it on: "The horse doesn't like". If that were a valid excuse for failure to train a horse to do something, we would never have started riding them in the first place.
