Why Does My Dog Lick Me? What’s Really Behind a Dog Kiss

You’re sitting comfortably on the sofa, and before long your dog is right beside you. First comes a quick sniff, then a lick across your hand. Maybe your arm is next, and sometimes, if you’re not quick enough, your face gets included too. For many of us, it feels pretty obvious: our dog is giving us a kiss.

But why does my dog lick me? Is it really a sign of love, or are we humans perhaps reading a little too much into it?

The answer is not quite that simple. Licking in dogs can be linked to affection, but it can just as easily be about attention, habit, communication, or simply the fact that your skin smells and tastes interesting to your dog.

Why does my dog lick me?

Licking is part of a dog’s life from the very beginning. A mother dog licks her puppies after birth, and licking continues to play a role in social interaction later on. So it is entirely possible that your dog licks you because he wants to be close to you and feels comfortable around you.

That said, not every lick should automatically be translated as “I love you.” Dogs do not communicate as clearly and directly as humans do. The very same behaviour can mean something completely different depending on the situation.

If your dog is lying next to you, relaxed, seeking physical contact and casually licking your hand, that usually points to a calm and familiar moment. A dog who seems nervous, turns his head away and repeatedly licks his lips may be communicating something very different.

Is licking really a sign of love?

It certainly can be. Affection in dogs may be one reason why your dog licks you. Especially with people a dog has a close bond with, licking can be part of friendly social interaction.

Experience often plays a role as well. Your dog licks your hand, you look at him, talk to him and give him a scratch. From his point of view, something pleasant happens after licking.

And dogs learn quickly.

If a certain behaviour regularly gets attention, there is little reason for your dog to stop doing it. So the supposed dog kiss may be a sign of affection while also being a behaviour that simply works well for your dog.

Licking is part of canine communication

Dogs use their tongues in many different situations. It is important, however, to distinguish between a dog licking a person and a dog repeatedly licking his own mouth or lips.

Scientific studies also suggest that lip licking in dogs can, in certain situations, be linked to how dogs perceive human emotions. However, this does not mean that every lick carries one clearly defined message.

The bigger picture is far more important.

Don’t just watch the tongue

If you want to understand what your dog is trying to tell you, pay attention to his entire body language. Is he loose and relaxed? Does he approach you willingly? Does he remain calm afterwards? If so, licking is probably part of a positive social interaction.

If your dog appears tense, pins his ears back, turns his head away or repeatedly licks his lips, stress in dogs, uncertainty or discomfort may also be involved.

A single lick usually tells you far less than the behaviour surrounding it.

Sometimes you simply taste interesting

There is also a much less romantic explanation for the dog kiss: your skin tastes interesting.

Sweat leaves salt on the skin. Add hand cream, traces of food and countless other smells that we barely notice ourselves, and suddenly your skin can become very appealing to a dog’s sensitive nose.

So if your dog gives you a particularly thorough licking after exercise, it does not necessarily mean he loves you more than usual in that moment.

You might simply taste a little better.

Why does my dog lick my hands and face?

Our hands are especially interesting to dogs. We touch food with them, prepare meals, pet our dogs and come into contact with countless things throughout the day. To a dog’s nose, your hand is almost like a small collection of scents.

Your face also carries plenty of interesting smells. There is another factor too: if a dog suddenly licks someone across the face, he is almost guaranteed to get a reaction. We laugh, speak to him, turn our head away or gently move him back.

From the dog’s point of view, that means one thing above all: attention.

Why does my dog lick me all the time?

Getting an occasional lick on the hand is usually nothing unusual. If your dog suddenly starts licking you much more often or seems unable to stop, however, it is worth paying closer attention.

Has the behaviour changed recently? Does it happen mainly in certain situations? Does your dog seem nervous or restless? Does he also constantly lick himself, the floor, furniture or other objects?

Very frequent or almost compulsive licking can have different causes. If you also notice other changes, such as pain, skin problems, loss of appetite or noticeably different behaviour, it is a good idea to have your dog checked by a veterinarian.

Should I let my dog lick me?

For a healthy person, the occasional dog kiss is usually nothing to worry about. Even so, it makes sense to be a little careful when it comes to dog saliva and hygiene.

Dog saliva should not come into contact with open wounds. A dog’s mouth naturally contains bacteria. In most everyday situations this is not a problem, but if those bacteria enter a wound, infections can occur.

People with weakened immune systems should also be a little more cautious. A quick lick across the hand is very different from prolonged licking of open skin or mucous membranes.

Do I need to stop my dog from licking me?

Only if it bothers you.

Not everyone enjoys being licked by their dog, and that is perfectly fine. A close bond with your dog does not depend on whether you allow him to lick your face.

If you want to reduce the behaviour, stay as calm as possible. Move your hand away or briefly end the interaction. Once your dog is calm again, you can give him attention.

Scolding usually does not help much, especially if the same behaviour has previously been rewarded with petting or friendly attention. From your dog’s point of view, it would be difficult to understand why his proven method suddenly causes trouble.

What does a dog kiss really mean?

Why does my dog lick me? There is probably no single answer.

Maybe your dog wants to be close to you. Maybe he wants attention. Maybe he has learned that licking reliably leads to petting. And sometimes your skin simply smells or tastes so interesting that he cannot resist.

The situation is therefore always the key. A relaxed dog who seeks your company and calmly licks your hand is showing something very different from a nervous dog who licks frantically and repeatedly.

And whether that relaxed lick on the sofa really is a little dog kiss after all?

That is probably something every dog owner can decide for themselves.

After all, not everything has to be translated scientifically.
