Once there was a dog who always wanted more than what he had. He was never satisfied with his food, and he always wanted more than what was given to him. One day, he was wandering in the streets when he found a bone. The bone looked big and juicy, and the dog was delighted.

The dog picked up the bone and started walking with it in his mouth. He was so excited about the bone that he forgot to look where he was going. As he was crossing a bridge, he saw his reflection in the water below. He thought that there was another dog with an even bigger bone than his, and he decided to snatch that bone too.

He barked at his reflection and dropped the bone from his mouth, only to realize that it was his own reflection. The bone fell into the water, and the dog was left with nothing. He had lost his bone because of his greed.

The moral of the story is that greediness can lead to loss and disappointment. It's better to be content with what you have and appreciate it, rather than always wanting more and risking everything for it.
