The act of canines using their tongues on another’s muzzle and auricles is a common behavior observed among domestic dogs. This action is multifaceted, serving various communicative and social functions within the canine world. It ranges from expressing affection and appeasement to gathering information about the other animal. One dog may initiate this behavior toward another, focusing on these sensitive areas of the body.
This behavior plays a significant role in establishing and maintaining social bonds within a pack. For younger dogs, it can be a sign of deference to older, more dominant individuals. Simultaneously, it can strengthen familial ties and reinforce social hierarchy. Historically, this practice could have been crucial for young canines to solicit regurgitated food from their mothers or other members of the pack, ensuring their survival.
