Toby the doctor Golden Retriever
Good old Toby had never studied medicine, however, he managed to perform the Heimlich maneuver. His mistress was choking to death with a piece of apple stuck in her throat, Toby did not hesitate and pressed her firmly on her chest which eventually dislodged the piece of apple killer.
Legend has it that once his mistress could breathe, our dear Toby never stopped licking the face of his lucky mistress.
