Once there was a hunter. He lived in a village. He had a dog. It was very faithful. One day, the hunter went to the city with his wife. He left his son at hire. A wolf came there. It entered the house and attacked the baby. The dog fought with the wolf and killed it.
In the evening, the hunter and his wife returned from the city. The dog was waiting outside for its master. When it saw its master, he licked its feet. The hunter saw the stains of blood on the dog's mouth.
He thought that the dog had killed his son. He became very angry. He took his gun and killed the dog. When he found his son safe inside the house and the wolf lying dead near him, he wept bitterly.
Moral: Haste makes waste.
