The behavior of canines attending to the aural region of conspecifics is a common observation. This action involves one dog using its tongue to repeatedly contact the outer and inner ear structures of another. The duration and intensity of the licking can vary considerably between individuals and interactions.
This activity serves multiple purposes within the canine social structure. It is often a display of affection or social bonding, reinforcing positive relationships between individuals. Moreover, it plays a role in maintaining hygiene, as the licking can help to remove debris, wax, or parasites from the ear canal. Historically, such grooming behaviors would have been critical for parasite control within a pack.
