A greedy dog stole a big, juicy bone from a butcher's shop and ran into the fields to enjoy it alone. He came to a stream with a narrow bridge. As he crossed, he looked down and saw another dog in the water, holding what seemed to be an even bigger bone.
Thinking the other dog's bone was larger, the greedy dog dropped his own bone into the water to snatch the bigger one. He jumped in with a splash, but the other dog—his own reflection—vanished.
In the end, the silly dog went home hungry. He lost everything because of his greed.
