Why doesn t my dog lick me

As a dog owner, you are probably familiar with dog face licking, whether you think it’s cute or not. But why do dogs lick your face? Should you stop the behavior?

Why Do Dogs Lick Your Face?

The common dog face licking behavior has evolved from the wolf puppy behavior of licking the mouths of adult dogs to prompt the regurgitation of partially digested food. This is how puppies transition from suckling their mother’s milk to eating partially digested food to more solid food.

Licking another dog’s face or a human’s face is a normal social behavior. Licking can be an appeasement gesture that signals a dog’s social deference. It can also be a signal to solicit food, more social information, a sign of affection or to solicit attention.

A dog licking faces or other body parts can also occur as part of grooming. Your dog may lick his canine housemate’s face and your face or other body parts. When your dog cannot reach your face, he may lick the closest body part, which may be your hand, arm or leg. In certain cases, the licking behavior can be interpreted as a sign of affection.

Some dogs may try to lick a complete stranger’s face. Why do they do that? It may be in an attempt to appease the stranger so that the stranger does do anything harmful or threatening to the dog. When dogs lick the face of children, it can be a sign of affection, appeasement or simply the act of cleaning food residue off their face.

Is Dog Face Licking a Health Risk?

For healthy children and adults, dog saliva is not a health risk for intact skin. It is not healthy, however, to allow your dog to lick an open wound on your skin. Their saliva may continue to keep the wound moist and open and allow bacteria to thrive, leading to a potential skin infection.

In the past year, there have been 12 cases reported to the CDC in which people have gotten sick from a bacteria carried in the dog’s saliva. In those cases, the bacteria Capnocytophaga canimorsus was the culprit. This particular bacteria is found in both dogs and cats and is harmless to them.

However, in cases where an individual has a compromised immune system, there is potential for the bacteria to cause an infection. The bacteria has to enter the skin through an open wound, such as from a bite or a cut on the skin.

Typically the dog has to have a high concentration of that particular bacteria, and their saliva has to come into contact with the open wound. It is best practice to wash your hands after petting any dog.

Should You Allow Your Dog To Lick You?

For most healthy people, a dog licking faces or other body parts should pose minimal health risk. If you are concerned, then do not let dogs lick your mouth or anywhere near an open skin wound.

I sometimes offer dogs the underside of my chin to lick. Then I immediately wash my face or apply antibacterial sanitizing spray or gel to that area of my face. Alternatively, I may allow them to lick my hand, and then I wash my hands afterwards or use an antibacterial spray or gel on my hands.

What If You’re Not a Fan of Dog Face Licking?

First, recognize that you might be reinforcing the licking behavior. If every time your dog licks your face, you give him attention, he is more likely to repeat the licking behavior. And if your pup licks you on the face or mouth when you are eating, and you give him a piece of your food, you are encouraging the behavior to continue.

If you do not like having your dog lick your face, you can always redirect them to exhibit affection and attention in a more acceptable manner to you, and be sure not to encourage the behavior.

Have you ever wondered why your dog seems so eager to lick your hands and face? Your dog could just be licking you to show their affection, but there are several other factors that may be at play.

Here are six reasons why your dog may be licking you.

One simple explanation is that your dog is excited to see you walk in the door.

"Essentially, it is their way of greeting you … like they are saying 'Hello!'," says Lara Sypniewski, DVM, a professor of small animal medicine at Oklahoma State University.

It may also be an evolutionary behavior — researchers have observed that some wild dog species will lick other members of the pack as a welcome when they return home.

Licking can be a way for dogs to bond with family members. For example, mother dogs will often lick their puppies to groom them or offer comfort.

Likewise, licking may be your dog's way of grooming you and showing closeness.

"Licking is a normal juvenile behavior in puppies and this behavior appears to be common with humans, especially when humans encourage the interaction," Sypniewski says.

Your dog is very sensitive to your emotional states. "Dogs have evolved alongside humans and appear to have the unbelievable ability to interpret and respond to human emotion," Sypniewski says.

If you appear to be upset, your dog may mirror this feeling, and respond by licking you, says Melissa Bain, DVM, a professor of clinical animal behavior at UC Davis. 

Dogs may also have a drive to comfort unhappy humans. A small 2012 study showed that dogs were more likely to offer comforting behaviors like approaching and nuzzling to people who seemed sad, rather than people who acted neutral. 

Your dog may learn over time that licking is an effective way to get your attention.

"As dogs lick, humans typically respond with attention and love, further reinforcing the dog's licking behavior," Sypniewski says.

Your dog may also seek your attention and lick you to signal that they want food.

This instinctual behavior mirrors that of wild dogs — puppies in the wild lick their mother's lips after a hunt to show that they're hungry and the mother will then regurgitate food for them. 

Your dog may want to lick you when you're sweaty after a workout — studies have shown that dog tongues can taste salt.

Your dog may also want to lick your face or hands after you eat a meal. Even if you don't think you have food on your face, your dog may be able to pick up more subtle, enticing smells with their incredibly sensitive noses.

According to Bain, there are several reasons why your dog might feel anxious, including:

  • Your behavior — "this may be because the owner has done something that the dog finds aversive, such as yelling," Bain says.
  • Some dogs may be prone to a general sense of anxiety, based on their disposition.
  • Dogs with separation anxiety may feel anxious when their owner returns home.

"When experiencing anxiety, they may look for ways to soothe themselves," Sypniewski says. Licking causes dog's brains to release dopamine and endorphins, hormones that can help them feel more relaxed.

"Dog owners may also respond to anxious licking by petting, cuddling, or offering encouraging sounds or words," Sypniewski says. This can encourage your dog to use licking as a way to get comfort in the future.

There are many possible reasons why your dog might lick you, ranging from showing love or just trying to get a taste of your dinner.

But keep in mind that excessive licking can also be a sign that your dog isn't feeling well. "Owners should also be aware that dogs can lick if they feel nauseous, so if this is a change in behavior for the dog, or if it is accompanied by other signs of illness, they should contact their veterinarian," Bain says.

Even the most affectionate dog owner can find these ‘kisses’ inconvenient at times so it’s a good idea to learn a bit about why they love a lick so you can curb this behaviour when needed.

Why do puppies lick?

To understand why they love to lick us, we first must understand what dogs use their tongues for to begin with and there’s a lot of reasons that come from their first few days of life:

  • As soon as a puppy is born, its mother will lick it to clean the afterbirth up, ensure it’s taken its first breath and stimulate blood flow. A new-born pup will be licked by its mother to help it go to the toilet and mum will use her mouth and snout to nudge any pups reluctant to feed.
  • Most mummy dogs will have several puppies per litter and with no hands or opposable thumbs, she takes care of them with her mouth – not to mention the odd nip when they need to be taught some basic puppy manners.
  • Most puppies are born with their eyes closed and don’t start to open them until they’re a week or two old. For those first couple of weeks, they’re reliant on their sense of taste, smell, and sound. They’re using their nose to find their milk and once they’re close, their tongues come out.
  • Over the next few weeks, they learn their place in the world through communication with their mother and siblings. When their behaviour needs to be modified, they’re given a nip, when they’re shown affection it’s a lick.

This behaviour will often follow them into adulthood, a grown dog will still nip to prove dominance and lick to show submission.

Why do dogs lick humans?

When puppies transition from being surrounded by their canine family to a human family, it can be a confusing time for them. As they grow and learn they keep some of their puppy behaviours to help them adapt to their new human pack including being led by their sense of smell and taste.

  • Therapeutic grooming
    • Dogs don’t just lick themselves to keep clean, they do it for comfort too. When we stroke their fur, they again associate this gentle repetitive motion with feeling relaxed.

They can’t stroke us like we do to them, but they can lick us to tell us they’re trying to do something nice and comfort us.

  • Scent
    • Does your dog ever go into lick overdrive when you’ve just got out the shower? You’re nice and clean and before you know it, you’re covered in dog slobber. From your dog’s perspective you don’t smell quite like you should, you’ve used shower gel or soap and for a while, it’s covered your natural scent your dog is used to.

By licking you, your dog’s trying to impart their familiar scent back onto you – don’t forget, their mothers would lick them to keep them clean, so they don’t understand why you’re using chemicals.

  • Taste
    • If you’ve just been for a run or it’s the end of a long hot day you might be looking forward to jumping in the shower but that’s when you’re at your tastiest to your dog.

The salt in human sweat is very appealing to dogs which is why they love to lick you when you’re especially sweaty.

  • Hierarchy
    • Submissive dogs lick other dogs to show they acknowledge who’s in charge. The dog doing the licking will often make themselves smaller, avoid direct eye contact and will often lick somewhere that could be vulnerable like the neck or near the eyes.

Sometimes they lick their human companions for the same reason, they know you’re the boss and they’re letting you know they know it.

  • Conditioning or accidental training
    • Some dogs will lick you because you’ve accidently taught them that’s how they’ll get your attention. If you react, even negatively, they can learn a quick lick is a good way to get you to interact with them even if your reaction is negative from your perspective.

Is it ok to let my dog lick me?

For the most part it will come down to the individual preference of the owner as to whether the odd lick is OK but there’s some basic science even the most dedicated dog lover should be aware of.

Cornell University lecturer, Dr. Leni K. Kaplan explains about zoonotic bacteria. Zoonotic bacteria is bacteria that can be passed from animals to humans and cause disease. Things like E.coli and salmonella can make humans very sick, and in the young, old and those with some underlying health conditions, it can prove fatal.

Whilst it’s unlikely these zoonotic bacteria can be absorbed through your skin, any dog saliva that gets near your eyes or mouth or even a cut on your skin, could make its way into your body.

Does that mean my dog should never lick me?

No, so long as you don’t mind, licking will help your dog understand your world. You might want to make sure they’re not licking any small children as this can cause hygiene and pack hierarchy challenges. Try to discourage too much face licking but the odd reassuring lick to the hand (assuming there’s no broken skin) will help your dog.

How do I stop my dog licking me?

Whilst dogs don’t understand the reasons you don’t want to be licked, they do understand why they want to lick you. If it’s a behaviour you want to discourage, it should be done gradually. Don’t scold them or offer any interaction, just walk away and they’ll start to learn a lick doesn’t garner an interaction.

In exchange, you need to make sure they’re still getting whatever they needed from the lick interaction. If they’re licking you for comfort, make sure they’re stroked often. If the only time your dog gets any interaction from you throughout the day is a pat on the head as you’re moving about the home, find a few minutes here and there to sit with them. Once they know they’ll get regular attention, the need to request it should recede.

If you’re able to identify specific behaviours behind their lick, you can combat it. For example, if you’ve been for a run and your sweaty, go straight to the shower without letting your dog lick you. If you’ve had something tasty to eat and your dog is intrigued by the smell, wash your hands before you interact with your dog.

Whilst dogs use their mouths to understand the world around them, it doesn’t mean they always know what’s good and bad for them. If you’re ever concerned your dog might have consumed something that can make them ill, it’s always advised you contact your vet.
