How can you train your horse in harvest moon hero of the leaf valley?

If you go to the blue sky ranch, you need to buy a reins and get you horse from the barn.pull it close to the door and press b and the horse will leave the barn. go outside after it has left. walk to the side of the horse and press x and you will jump on your horse. do this for about a month and your horse will be fully trained!. I hope I helped!
