<2006 “‘Wrenne raised his eyebrows. ‘After arresting you on the wharf? I would have sent him off with a flea in his ear.’”—Sovereign by C. J. Sansom, page 610> [[story placed in 1541]]
My first thought was that in the above quote flea in your ear might be an anachronism and my second thought was that it was a variation of bug in your ear meaning idea or hint; thus put a bug in someone’s ear. But the first turned out to not be the case and the second turned out to be questionable.
FLEA IN YOUR EAR: Said of a stinging or mortifying reproof, rebuff, rebuke, or repulse, which sends one away discomfited; a sharp or humiliating reprimand; hint, warning, disquieting disclosure chiefly in phrase to go (send, etc.) away with a flea in one's ear. <The old lady thought he was impertinent and sent him away with a flea in his ear.>
Etymology: In Middle English and later, flea in one’s ear had the meaning ‘something that causes alarm or anxiety.’ (cf. French avor la puce à l’oreille) The expression refers to the restless and distressed behavior of a dog afflicted with a flea in its ear. The phrase first appeared circa 1430, however, since its meaning changed over time (see above definition), and it is not always clear which meaning is meant nor when the later meaning took root, it is difficult to say if its use in the quote above is an anachronism or not.
