A vacationing Penguin, who is a licensed and practicing doctor, is driving down the highway and comes upon Dog, who is lying unconscious on the side of the road. Penguin renders medical aid that saves Dog's life. The injured, unconscious Dog did not solicit the medical aid and was not aware that the aid had been rendered; however, Dog received a valuable benefit.

2. Will Dog have to pay Penguin for the medical service? (Don't answer just 'yes' or 'no'. Support your answer.)
