He Is Na Dog, He Is A Lam is a poem by William Dunbar addressed to Queen Margaret Tudor of Scotland. The theme of the poem follows on from the same author's work "Of James Dog" in which Dunbar had complained about the allegedly rude behaviour of the Queen's servant of the same name. James Dog was referred to as "A dangerous dog". In He Is Na Dog, He Is A Lam Dunbar declares to have renounced his former opinions of the "dangerous dog" because, apparently, he has been helpful to the poet. James Dog is subsequently compared to a lamb.
