There was a merchant of Qingzhou who was much away on business, often for as long as an entire year. He had a white dog at home, and during her husband’s absences his wife encouraged the dog to have sexual relations with her. The dog became quite accustomed to this.

One day, the merchant had just returned home and was in bed with his wife when suddenly the dog burst into the room, climbed up on to the bed, and bit his master to death.

When the neighbors came to know of this, they were most indignant and reported the matter to the local magistrate, who interrogated the woman under torture and, when she still refused to confess, had her thrown into the county jail. He gave orders for the dog to be brought on a leash, and then summoned the woman into the tribunal. The moment the dog saw her he rushed forward, tore off her clothes with his teeth, and leaped on top of her, adopting a posture that was unmistakably sexual. The woman could no longer deny the charge brought against her. The magistrate sent them both, woman and dog, under guard to the higher court in the provincial capital.
