In the 11th Round, Dong Zhuo attempted to kill Huang Jin High School's supervisor, Zhang Bao, but Piggy suddenly jumped into the middle of the action, causing the spell that Dong Zhuo was casting to backfire and switch bodies with the dog.
The dog and Dong Zhuo's souls remain in each other's bodies until Li Ru finds out about the swap and helps switch them back to each other's bodies. It is never revealed what happened to the hound after their bodies were re-switched.
