"Roog" tells the story from the point of view of a dog named Boris, who observes his master's carefully stored food in containers outside of their house day after day. Unbeknownst to the dog, these are the human's trash cans for garbage.

Philip K. Dick sold approximately fifteen short stories himself before becoming a client of the Scott Meredith Literary Agency. "Roog" was his first sale but not his first published story.
