The Hungry Little DogThe Hungry Little Dog
People thought the dog was mad, but he was not mad, he was just a very special...
Last Updated On: Saturday, April 7, 2007

There was, once upon a time, a little hungry dog. He had no home, no name, and very often no food.

He would hunt around dustbins, and eat the most surprising things-like plum stones and paper bags, but he never had a pain . . . for really he was a very special dog.

When people were having meals, he walked around the houses with a hungry look, and the kind people nearly always gave him something to eat.

Sometimes the little dog felt very excited, and for no reason at all he would rush over the fences and knock over everything that came in his way.

People thought the dog was mad, but he was not mad, he was just a very special sort of dog.

One day a gentleman watched these strange goings on with surprise. Then he, too, jumped in the air and danced for joy-for he had an idea.

"This dog would be just right for the films," he said. "He is JUST what I have been looking for."

As the dog looked hungry, the film director took him to the butchers.

So the little hungry dog was hungry no more. He had plenty of food, a good home, and his master was the kindest man any dog could have.

The little dog was a born actor and his antics on the screen made everyone clap their hands and laugh until their sides ached.

Of course, he made a lot of money for his master, and more did he have to search in dustbins for his food. He could choose just what he fancied for dinner, go out when he liked, and stay in bed late in the mornings.

The little black dog was very pleased with himself.

"Woof! Woof! I am not a hungry little dog now-I AM A FILM STAR!"
