What is the best training method for a percheron horse if you are training it to jump?

Well I would look at the horses orgin and if he/she has a mother or father that jumps then i suggest training it in heavy horse jumping!! ---- it may not want to jump at all maybe from a bad experience or absulutly no reason at all if it is no reason at all just keep persisting and it will so love jumping but remember start out on trot poles or cavelletis
