Question
Why does my dog lick me?
The short answer
There is no single proven reason. Mothers lick their pups, and many dogs keep licking as a friendly greeting. Dogs also lick because it gets attention, because your skin tastes salty or of lotion, and sometimes to ease a tense moment. If you would like less of it, reward calm greetings and give your dog something else to do. Constant licking needs a vet check. Kroki, a reward-based training app for puppies and dogs, teaches a hand target and calm greetings in short steps.
How to do it, step by step
Decide how much licking is fine for you
Occasional licking is harmless for most people, and some owners enjoy it. Agree as a household what is welcome, for example hands but not faces, so your dog gets the same answer from everyone.
Notice when it happens
Licking at the door is usually greeting. Licking after a run or shower may be about taste. Licking while you are tense, or when someone leans over the dog, may be your dog trying to calm things down. The situation tells you which answer fits.
Give the mouth a different job
Teach a hand target: hold two fingers near your dog’s nose, and when it bumps them, say “Top!” and reward. Now you can ask for a quick nose touch instead of a lick when you come home. A chew or a lick mat also gives the urge somewhere to go.
Reward calm greetings
When you arrive, greet your dog low and calmly and reward it while all four paws are on the floor. Many dogs lick less when greetings are short and quiet rather than a big, exciting event.
Pause attention briefly, without scolding
If licking goes on longer than you like, stand up or move your hand away for a few seconds, then invite your dog back for a hand target or a stroke. Pushing it away or saying “no” is still attention and can keep the licking going.
Give space when licking looks worried
If your dog licks while its body is low, its ears are back or it turns its head away, it may feel uneasy. Stop what you are doing, give it room and look at what made the moment stressful.
Puppy or grown dog?
Puppies lick a lot, often mixed with nibbling, as they explore and greet. Keep greetings calm and give plenty of chews during teething. A grown or rescue dog that suddenly starts licking much more, licks objects or the floor, or licks with a tense body may be uncomfortable or worried, so a vet check comes before any training.
What we know about why dogs lick people
Surprisingly little research has looked at why dogs lick people. Vets and behaviour specialists agree that it is probably a mix of reasons. VCA Animal Hospitals names licking learned in puppyhood, when mothers lick their pups to clean and stimulate them, showing affection, seeking attention, and simply tasting salty or sweaty skin. It also notes that pushing a dog away or telling it to stop can reward the licking with attention (VCA Animal Hospitals).
Some popular claims, such as licking releasing feel-good hormones in the dog’s brain, are often repeated but have not been well studied in dogs licking people. It is fair to say that licking seems to feel good to many dogs, but the exact reasons are not proven.
Licking can also be a sign that something is wrong. VCA notes that excessive licking of people or objects could be related to anxiety or pain (VCA Animal Hospitals). In a small study of dogs that licked floors, walls and other surfaces excessively, most turned out to have a gastrointestinal problem, and many of them licked much less once that problem was dealt with (Bécuwe-Bonnet and colleagues 2012). So if licking is constant or new, think about health first.
Common reasons, and what they can look like
- Greeting: licking at the door or when you wake up, with a loose, wiggly body.
- Attention: licking when you are busy, which stops as soon as you look or talk.
- Taste: licking after exercise, a shower, cream or a meal.
- Calming a tense moment: licking with a low body, ears back, a turned head or yawning.
- Habit: licking during cuddles because it has always been part of them.
Hygiene and sensible limits
- Do not let your dog lick open wounds, eyes or the mouth area.
- Keep face licking away from babies, small children and people with a weak immune system.
- Wash your hands after cuddles before you eat.
- Keep your dog’s vaccinations and worming up to date, as your vet recommends.
When to see a professional
Most licking is normal. Have it checked if:
your dog licks constantly, licks floors, walls or the air, or the licking is new and comes with vomiting, diarrhoea, gulping or a change in appetite
Have a vet take a lookyour dog licks or chews its own paws or skin until it is red, bald or sore
Have a vet take a lookthe licking seems driven by worry: your dog cannot be interrupted, looks tense, or licks mostly when left or handled

Frequently asked questions
Is my dog licking me a sign of love?
Often licking is a friendly, social behaviour, so many people read it as affection. It can also mean your dog wants attention, likes the taste of your skin, or feels unsure.
Why does my dog lick me after I shower?
After a shower your skin smells different and may taste of soap, lotion or water, which many dogs find interesting. It is usually harmless; offer a hand target instead if you would rather avoid it.
Why does my dog lick me when I stroke it?
Some dogs lick back during cuddles as part of the social exchange, others because they are excited. If your dog licks while leaning away or tensing, stop and give it space.
Why does my dog lick my face in the morning?
Morning licking is usually a greeting after the night, and your skin may taste salty. If you prefer, sit up before you greet your dog and ask for a nose touch on your hand.
Is it unhygienic to let my dog lick me?
For most healthy adults the occasional lick on the hands is low risk. Keep licking away from wounds, eyes and mouths, and from babies or people with a weak immune system.
How do I get my dog to lick me less without hurting its feelings?
Give it a different way to say hello, such as a hand target or bringing a toy, and reward that. Briefly turn away when licking starts, then reconnect calmly once it stops.
When is licking a sign of stress in dogs?
Licking can be a sign of stress when it comes with a low or stiff body, ears back, a turned head, yawning or lip licking. Then the kindest response is to give space and look at what is worrying your dog.
