why do dogs lick your face

Dogs lick your face mainly as a form of communication and affection. It is an instinctual behavior rooted in their ancestry, where wolves lick the faces of pack members for greeting, submission, or bonding. Dogs also lick your face because they are attracted to the taste and smell—such as food remnants, sweat, or even the scent of lotions and cosmetics on your skin. Additionally, licking releases pleasurable endorphins for the dog, which can soothe anxiety and stress, making it a comforting action for them. Often, face licking by dogs is also a way to get attention or show submission and respect toward their human "pack." This behavior can strengthen the bond between the dog and the owner and can be interpreted as a sign of love or social grooming.
