You walk in the door from a long, hard day.
Your dog greets you and starts licking your face as if you are some kind of doggie lollipop.
Some people think this lick greeting is adorable. Others cringe at it.
Why do dogs lick your face?
In a nutshell, or doggie treat, licking is one way dogs communicate. Depending on the situation, it can mean affection, excitement, curiosity, or simply that your dog’s in investigative mode.
Dogs Often Lick to Show Affection
One of the most common reasons dogs lick your face is because they enjoy being around you.
Licking generally releases feel-good chemicals in dogs. That, in turn, can become a learned and repeatable behavior, especially if you reward your dog with:
- Petting
- Giggling
- Attention
- Belly rubs
- A treat
When I first adopted Henry, he licked everyone’s face. I don’t really like my face licked. So, I eventually taught him that face licking wasn’t something I enjoyed. Today, he’d much rather sit beside me while I hold his paw. It’s become our own little way of showing affection, and it’s much less slobbery.
They’re Gathering Information
Dogs use their incredible sense of smell and taste to investigate where you’ve been, what you’ve been doing, and even what you’ve eaten.
Face licking can be your dog’s way of saying “Human, where have you been and what did you do?” Your face is the answer book. They “read” it through licking and smelling.
That means all that licking may just be a way of gathering information about you.
You Taste Good
Licking can be your dog’s way of saying, “I need you, Human!”
It could be that they want to play, feel like cuddling, need a walk, or just want to be close to their favorite human.
If every face lick earns a reward, then your pup learns that licking works. This can then quickly teach your buddy that face licking is an effective way to get what they want from you.
Even telling your dog “No, stop!” can be rewarding if your pup is simply looking for your attention. Dogs repeat behaviors that get a response.
Could Face Licking Be a Problem?
Generally, the occasional face licking is perfectly normal.
But if your dog suddenly starts licking obsessively or can’t seem to stop, it may be worth talking with your veterinarian. Excessive licking can sometimes be linked to stress, anxiety, nausea, allergies, or other medical conditions.
Pay attention to any sudden changes in your dog’s behavior rather than the licking itself.
Should You Let Your Dog Lick Your Face?
Honestly, this really comes down to personal preference.
Many people enjoy those enthusiastic “dog kisses.” Others prefer to redirect their dog’s licking to a favorite toy, belly rub, or another greeting behavior, like offering a paw.
If you don’t enjoy face licking, don’t punish the behavior. Instead, simply reward another greeting, like sitting politely, leaning against you, playing with a favorite toy, or offering a paw with a cookie. Over time, your dog will learn which behavior gets your attention.
Is It Safe To Let Your Dog Lick Your Face?
A face lick exposes you to possible parasites and bacteria. The exposure is escalated if your dog licks your nose, mouth, or eyes.
If you have a compromised immune system or young children in your house, you may want to reconsider the happy face licks.
Even if you’re healthy, washing your face after a slobbery greeting is a good habit to help reduce exposure to bacteria.
The Bottom Line on Why Dogs Lick Your Face
There is definitely a clear divide between people who love it when their dogs lick their faces, and those who don’t.
It’s really not your dog trying to gross you out. Your pup is simply showing affection with those “kisses”, gathering clues about your day, leaning into a behavior that gets them a desired outcome, or even indulging in your taste.
The next time your dog tries to lick, take it as a compliment. But you can also redirect to a game of fetch.
Fun Dog Fact: Puppies naturally lick their mothers and littermates from a very young age. It's one of the first ways they learn to communicate and bond with other dogs.
