If you are a dog lover, you may know every funny detail of dog. How about dogs chasing their tail? It look so funny, they try to find their tail and move around like a rolling die. For this German dog is different. He looks so big and strong but he is in his own trap. He doesn’t know what appears under him. It actually is his shadow. He paws it many times but he still cannot figure it out what it is.
What if he sees himself in the mirror or his reflection? I bet, he must paw and bark until he feels exhausted.
