Which proactive management technique aims to change a dog's emotional state regarding a trigger like the mail carrier?

Answer

Counter-conditioning, by pairing the sight/sound with a high-value treat before the bark starts.

To manage alert barking, the approach involves counter-conditioning, which pairs the stimulus (mail carrier) with something highly positive, thereby changing the dog's emotional reaction to the trigger.
