If your dog licks your hand, face, or arm, many people call it a “kiss.” It often looks affectionate — and sometimes it is — but canine behavior experts say licking can mean several different things. Depending on the situation, it may be affection, communication, stress, or simply curiosity.
The image captures a common misunderstanding: a dog’s lick is not always a human-style expression of love. It can be more complex than that.
Why Dogs Lick Humans
Dog licking is a natural behavior that starts in puppyhood. Puppies lick their mother and littermates as part of bonding and communication. Many adult dogs continue this behavior with humans.
Common reasons include:
affection
seeking attention
exploring scents and tastes
stress relief
social bonding
submissive behavior
