Jealousy is a dog’s bark which attracts thieves.

In this aphorism, jealousy is figured not as a protective instinct but as a noisy, self-defeating alarm. A dog’s bark is meant to warn off intruders; Kraus reverses the expectation by suggesting that the very display of suspicion and possessiveness can advertise vulnerability and provoke the outcome it fears. Jealousy, in this reading, becomes performative: it publicizes insecurity, invites rivalry, and can erode trust until betrayal (the “thieves”) becomes more likely. The line fits Kraus’s satirical moral psychology—exposing how social emotions, when loudly acted out, often create the conditions for the harm they claim to prevent.
