The dog wants to be a tiger. He sees a little boy, a couple, and another dog who think of him as just a “dog”. He tries to become a tiger and evens rolls around in mud and licks stripes off of his fur so he looks like a tiger. When the little boy is in trouble in the water, the dog doesn’t hesitate to help him, even though his stripes will be ruined. After saving the boy, the couple and little boy now call him Tiger, and the dog calls him sir.
