1. Decoding The Lick: Understanding Why Dogs Lick Faces
Dogs licking faces is a multifaceted behavior, with roots in instinct, communication, and affection. Understanding these motivations can help pet owners better interpret their dog’s actions. It’s not always about “I love you”; sometimes, it’s about “You have something interesting on your face” or “I want your attention”.
2. The Instinctual Roots Of Dog Licking Behavior
2.1. From Wolf Cubs To Domestic Pups: The Evolutionary Link
Licking behavior in dogs is deeply rooted in their evolutionary history. Wild canid pups, like wolf cubs, instinctively lick their mother’s face to stimulate regurgitation of food. This behavior, critical for survival, ensures the pups receive nourishment. Domestic dogs inherited this instinct, and although they no longer need to stimulate regurgitation, the act of licking remains a deeply ingrained behavior. According to a study published in Applied Animal Behaviour Science, early experiences can significantly shape a dog’s behavior later in life.
2.2. Hunger Signals: Communicating Needs Through Licking
Domestic pups also use licking to signal hunger to their mothers. By licking the mother’s muzzle, puppies communicate their need for food and attention. This behavior is often transferred to human interactions, where dogs may lick their owners’ faces to indicate they are hungry or want something.

3. The Affection Connection: Is Licking a Sign Of Love?
3.1. “Kissing” Culture: The Human Interpretation
Humans often interpret face licking as “kissing,” attributing it to a sign of affection. While this can be true, it’s essential to understand that dogs may have different motivations. Licking can indeed be a way for dogs to show they like you, but it’s also a way they appease and build social bonds.
3.2. Appeasement And Social Bonding: The Canine Perspective
In canine social interactions, licking another dog’s face signals friendly, non-threatening intentions. It’s a gentle approach designed to elicit a positive response and reinforce social bonds. This behavior is often transferred to humans, where dogs use licking to communicate their friendly intentions. A study in the Journal of Veterinary Behavior notes that licking can be a key element in maintaining social hierarchy and harmony within a dog pack.

4. Seeking Attention: How Licking Gets Results
4.1. The Attention-Seeking Loop: Positive And Negative Reinforcement
Dogs quickly learn that licking gets them attention. Whether the response is joy or displeasure, dogs interpret it as attention. Because dogs struggle with the nuances of positive and negative feedback, they often see all attention as a reward.
4.2. Context Is Key: Interpreting Licking With Other Body Language
It’s important to consider the context and other body language when interpreting licking behavior. For example, a dog that wakes up from a nap, stretches, and then starts licking your face may be ready to play. However, a dog that is licking excessively and showing signs of stress may be licking for a different reason.
5. Licking As A Request For Space: The “Kiss To Dismiss”
5.1. Understanding The “Kiss To Dismiss” Phenomenon
The term “kiss to dismiss” was coined by Jennifer Shryock, a certified dog behavior consultant. This refers to licking behavior used to get a person to move away. If a dog is licking a person (child or adult), moving their head forward, has dilated pupils, a tucked tail, or is alternating between forceful licking and turning their head or body away, it’s a sign that the dog is licking to create space.
5.2. Recognizing Stressful Situations And Intervening
Pet parents should be aware of potentially stressful situations, like interactions with young children or being overwhelmed by new people. Intervening by gently calling the dog away or removing the stressor can prevent escalation and ensure the dog’s comfort and safety.
6. Stress Relief Through Licking: A Self-Soothing Mechanism
6.1. Continuous Licking As A Sign Of Stress Or Anxiety
Periods of continuous licking can indicate that a dog is struggling with stress or anxiety. They may choose specific textures like a rug or a couch, or they may lick themselves or you more often. This licking can be difficult to interrupt because it is intentional and self-soothing.
6.2. Endorphin Release: The Calming Effect Of Licking
Licking promotes the release of endorphins, which have a calming effect on dogs. Providing a LickiMat® or LickiMat® Wobbler Bowl loaded with wet dog food, peanut butter, or yogurt can help redirect this behavior into a positive outlet. These tools encourage licking in a controlled environment, helping to alleviate stress and anxiety.

7. The Grooming Instinct: Maintaining Cleanliness
7.1. From Puppyhood To Adulthood: The Evolution Of Grooming Behavior
Dogs use their tongues to groom themselves and others. This behavior starts early in life when mothers lick their pups to stimulate bowel and bladder movement and clean their young. As dogs mature, they continue to use licking as a way to maintain cleanliness and remove scents they find offensive or attractive.
7.2. Attracted To Scents: Ear Wax, Blood, And Other Odors
When dogs groom themselves or each other, they are drawn to scents like ear wax or blood. They either like the taste or find it offensive and lick to eliminate it. This behavior can extend to licking humans, particularly if they detect interesting scents on our skin.
8. The Taste Factor: Why Your Face Is So Appealing
8.1. A Playground For Noses And Tongues: Exploring Human Faces
Human faces are full of scents, bacteria, food particles, and other interesting contaminants. A human face is a playground for a dog’s nose and tongue. Eyes produce tears, skin may be salty from sweat, and mouths contain leftovers from our last meal.
8.2. Salty Skin, Tears, And Food Residue: The Irresistible Combination
These things make faces very attractive to a dog. The combination of saltiness, moisture, and lingering food scents can be irresistible to a dog’s sensitive senses.
9. The Hunger Connection: Licking As A Mealtime Reminder
9.1. Regurgitation Expectations: Debunking The Myth
While dogs aren’t expecting you to regurgitate food, they could be licking you to get your attention and alert you that it’s time for snacks. This behavior is linked back to their puppyhood instincts, where licking was used to stimulate feeding.
9.2. Attention-Seeking At Meal Times: Communicating Hunger
By licking your face, your dog may be trying to remind you that it’s time for their meal or a treat. This behavior is more likely to occur around typical feeding times or when the dog associates your presence with food.
10. Health And Safety: Is Dog Licking Safe?
10.1. Capnocytophaga: Understanding The Germs In A Dog’s Mouth
Dogs licking our faces is generally a low-risk event. A dog’s mouth contains germs called Capnocytophaga, which are also found in human mouths and typically do not pose a threat. Even when exposed through a bite or scratch, the risk of illness is low, according to the Centers for Disease Control and Prevention (CDC).
10.2. When To Exercise Caution: Open Wounds, Immune Systems, And Allergies
However, if you have an open wound, a compromised immune system, are taking certain medications, or are allergic to animal saliva, the risk of infection or allergic reaction caused by being licked could be higher. In such cases, it’s best to avoid face licking and take precautions.
10.3. Seeking Medical Advice: When To Consult A Doctor
If you are unsure about any exposure to a dog’s saliva, it’s safest to seek medical attention. Prompt medical advice can help prevent potential complications.
11. What To Do After A Lick: Hygiene And Training Tips
11.1. Washing Up: The Importance Of Basic Hygiene
If you have been licked and feel uncomfortable, wash up with warm water and antibacterial soap. If you are allergic to dogs, be sure to wash off any saliva or fur. This simple step can help minimize any potential risks.
11.2. Discouraging Face Licking: Training Techniques And Alternatives
To discourage dogs from licking your face, consider training your dog to understand a cue that lets the dog know when to stop, or give them a different target, such as your hands. Positive reinforcement techniques can be highly effective in redirecting this behavior.
12. Addressing Common Questions: FAQs About Dog Licking
12.1. Why Do Dogs Lick Your Face When You Cry?
Tears are droplets that contain more than just saline. The popular thought is saltiness causes a dog to lick our face during and after crying. However, emotional tears also contain additional hormones and proteins. Your dog could smell those components and want to lick them up, either to taste what they smelled or to clean the area, so the scent is no longer present.
Studies show that dogs’ emotional states sync with their pet parents. If you’re upset, there’s a chance your dog will pick up on it. Licking can be a soothing behavior for pups, and they can use it to soothe you—which in turn soothes them.
12.2. Why Do Dogs Lick Your Face In The Morning?
Likely reasons include the number of bacteria that accumulate in your mouth, the scent of your morning breath, your dog is ready for breakfast, or they are just ready for you to get up. Morning breath is particularly appealing to dogs due to the concentration of bacteria and food particles.
12.3. Why Do Dogs Lick Your Face And Ears?
Both areas are full of bacteria, skin cells, perspiration, and food particles. If it smells good, then licking follows. If you laugh and giggle as a result, your dog learns that their behavior has a positive outcome and will lick your face and ears more in the future to engage.
