Please summarize the story of the fox and the dog in Aesop's fable and tell the moral.

The fox slipped into the flock, picked up a lamb and touched it hypocritically.

The dog asked the fox what he was doing, and the fox said, "I'm teasing him."

The dog added, "Now if you don't put this lamb down, I'll let you taste the dog's touch."

The story is that we should not have the slightest kindness to a cunning man like a fox, but should know how to answer blows with blows. Deal with a man as he deals with you, and the trick of a liar will always be seen through, even if the bad guy wears a good coat, he will be discovered by others.
