The more broke and trained your horse is the better, some horses temperment and confidence in the handler can make them naturals. My horse is very broke and trained and is a natural. When I first started, I shot the bow around him, and he was good with it, rubbed him with it, nothing. got on and moved the bow around and let him see I was not beating him, all went well so I shot an arrow from a short draw, maybe a bit of a flinch but nothing big so kept going and soon was shooting from a gallup. I shoot at a hay bale so so he gets a bite when I pull arrows, then I shot bareback and used the bale to hop back up from. Again this is from a very broke horse so you just got to take each horse and see what they know and how they are going to accept it. The thing is you have to be able to drop the reins ab be able to trust the horse, Mine is a reining horse and will guide to where I am looking and I do not use any kind of a rope fence to make him go where I want to go. Give it a try, have fun, and let me know how he does and any problems you run into.
