I know this is an old post, but being a farrier I feel a need to reply.
As many of the posters have said, it's NOT the farrier's job to train your horse.
It's not the farrier's job to risk their lives.
If a horse is upset it should NOT be in crossties, the owner (or someone who knows the horse) should be holding it.
If the horse is too upset, I may suggest twitching or putting on a "Stableizer" ( The Stableizer
) or some sort of war bridle, or sedation if available.
It is up to the horse owner have their horse trained and be able to control their horse.
I personally have charged full price and not completed a job when the horse esculates to the point of being dangerous. One reason I will charge full price is because I don't want to come back to work on a dangerous horse, especially if the owner isn't cooperating with the training or restraining of the animal.
Have you ever seen a farrier with their knee blown out from a kick?
Have you ever seen a farrier with a broken arm or leg from a kick?
Have you ever seen a farrier with their face kicked in?
Have you ever seen a farrier being thrown 30 feet from a hind leg kick?
I have seen all of these, it's not pretty, there is no reason NOT to do everything you possibly can to keep the farrier safe.
