Horses in survival craft can be " tamed," like camels, but if you hit it, it gets afraid of you and will run away from you if you walk up to it. To tame it, you have to craft a saddle. Once the saddle is crafted, then walk up to a horse. The sneak mode button will turn into a mount button. First place a saddle on the horse before mounting so the horse will not fight against you and make you go out of control. If you don't want to chase after your horse, then craft a whistle to summon your horse(s). The different horse are palomino, white, black, and chestnut.
