Dogs lick for a variety of reasons, and understanding why can help you build a stronger bond with your furry friend. In this article, we’ll dive into the science, psychology, and health implications of dog licking.

“Dogs do speak, but only to those who know how to listen.” – Orhan Pamuk
So, let’s get started and uncover the secrets behind your pup’s licks!
The Science Behind Dog Licking
Instincts from Puppyhood
From the moment they’re born, puppies are licked by their mothers. This behavior serves several purposes:
- Cleaning: Mother dogs lick their pups to keep them clean.
- Stimulation: Licking helps stimulate breathing and digestion in newborn puppies.
- Bonding: It strengthens the bond between the mother and her litter.
As puppies grow, they mimic this behavior, licking their littermates and humans as a way to show affection and communicate.
Taste and Smell: A Dog’s Superpowers
Dogs experience the world through their noses and tongues. Their sense of smell is up to 10,000 times more powerful than ours, and their taste buds, while fewer in number, are highly sensitive. When your dog licks you, they’re gathering information about you—what you ate, where you’ve been, and even how you’re feeling.
Fun Fact: Dogs have a special organ called the Jacobson’s organ (or vomeronasal organ) that allows them to detect pheromones and chemical signals. This might explain why they’re so interested in licking salty skin or sniffing (and licking) your shoes!
What Your Dog Is Trying to Tell You
Affection and Bonding
One of the most common reasons dogs lick is to show love. When your dog licks you, they’re essentially giving you a “kiss.” This behavior releases endorphins in their brain, making them feel happy and relaxed. It’s their way of saying, “You’re part of my pack, and I care about you.”
Attention-Seeking Behavior
Dogs are smart creatures. If they notice that licking gets your attention—whether it’s a laugh, a pat, or even a gentle scolding—they’ll keep doing it. It’s their way of saying, “Hey, look at me!”
Stress and Anxiety Signals
Excessive licking can sometimes be a sign of stress or anxiety. For example, if your dog licks themselves, you, or objects obsessively, it might be a coping mechanism. Pay attention to other signs of stress, such as pacing, whining, or destructive behavior. If you notice these signs, consider consulting a vet or a professional dog behaviorist to address the underlying cause.
Health Implications of Dog Licking
Is Dog Licking Safe for Humans?
For the most part, dog licking is harmless. However, dogs can carry bacteria like Salmonella or E. coli in their saliva, which can be transmitted to humans. While the risk is low, it’s a good idea to wash your hands after a slobbery session, especially before eating. Additionally, avoid letting your dog lick open wounds, as this could introduce bacteria and lead to infection.
Did You Know? A study published in the journal PLOS ONE found that dog saliva contains enzymes that can help heal wounds. This might explain why dogs instinctively lick their own injuries—and sometimes yours! It’s important to note that human wounds should be treated with proper medical care to avoid infection.
When Licking Becomes a Problem
While occasional licking is normal, excessive licking can indicate underlying issues, such as:
- Allergies: Dogs with skin allergies may lick to soothe irritation.
- Pain: Licking a specific area could signal an injury or discomfort.
- Boredom: A lack of mental or physical stimulation can lead to compulsive licking.
If your dog’s licking seems excessive or out of character, it’s worth investigating further.
How to Manage Excessive Licking
Training Tips
If your dog’s licking is becoming a nuisance, try these strategies:
- Redirect Their Attention: Offer a toy or treat to distract them.
- Teach the “No Lick” Command: Use positive reinforcement to train your dog to stop licking on command.
- Provide Mental Stimulation: Puzzle toys and interactive games can keep your dog entertained and reduce boredom-related licking.
When to Consult a Vet
If your dog’s licking is accompanied by other symptoms like redness, swelling, or changes in behavior, it’s time to consult a vet. They can rule out medical issues and recommend appropriate treatment.
