One day, Shiro led the old man up a nearby mountain. When they reached the top, Shiro barked, "Arf Arf - Dig here! Arf Arf - Dig here!" As the old man began to dig, to his amazement, sparkling gold coins started pouring up from the ground."Let me borrow Shiro!" The greedy old man heard about this and, grabbing Shiro, forced him to take he and his wife to the mountain. "Where's the gold?" the old man demanded. Frightened, Shiro began to whimper. "Ah, so it's here," said the old man, and he began to dig. But instead of gold coins, garbage began pouring up from the ground.
