The situation with seeing-eye dogs is similar. Ko once took a seeing-eye dog which he had gotten from the Institute for the Blind out on a walk. When they reached an intersection, the dog stopped. After giving it repeated commands, the dog finally moved forward again--leading Ko into a puddle.
導盲犬的情況也大同小異，柯明期曾帶著盲人重建院的導盲犬上路，結果到了路口導盲犬就不走了，在他連續下達幾次命令後，導盲犬終於帶他往前踩進一灘水裡。
