Roverandom is a novella by J. R. R. Tolkien, originally told in 1925, about the adventures of a young dog, Rover. In the story, an irritable wizard turns Rover into a toy, and Rover goes to the moon and under the sea in order to find the wizard again to turn him back into a normal-sized dog. The author wrote Roverandom for his son Michael to amuse him upon the loss of his favorite toy, a little leaden dog which he lost on a beach of grey stones This charming tale remained unpublished for more than 70 years.
