A dog has a piece of meat in his mouth. He’s going to eat it at home. As he is walking on a bridge, he looks down and sees himself in the river. That dog looks like him and he has a piece of meat in his mouth, too. The dog thinks it’s another dog. So he says to himself, “I want to eat more meat. I must make him run away from here and get the meat in his mouth. Then I can have two pieces.” He opens his mouth to bark. That dog in the water barks at him. Suddenly, his meat goes down into the water. The dog is so angry, he jumps into the water to catch the other dog.
