Why Do Dogs Lick Themselves?

They especially love to do this when they’re ignoring you.

Most common reasons your dog licks you when you pet them

Affection and bonding

This one’s the crowd-pleaser: Your dog licks you because they love you. Licking is a natural way for dogs to show affection and strengthen their bond with you. Just like puppies lick their littermates and mothers to express closeness, adult dogs carry this instinct into their relationship with their human family.

Studies show that licking releases endorphins in dogs, which are natural feel-good chemicals that create a sense of pleasure and comfort. It’s a win-win: you pet them, they feel loved, they lick you, and they feel even more loved.

Exploration and sensory engagement

 Dogs explore the world with their mouths more than their eyes or paws. When you reach out to pet them, your scent and the feeling of connection trigger curiosity. Licking is their version of checking you out.

That lotion you just put on? The faint smell of whatever snack you had three hours ago? All fair game for investigation. Pups may be decoding your story one lick at a time. To your dog, your skin is an interactive scratch-and-sniff book with bonus cuddles.

Instincts and grooming

Licking is a behavior deeply rooted in canine instinct. According to Dr. Ushi, a veterinarian in Wesley Chapel, Florida, mother dogs lick their pups to groom them, encourage them to breathe, and stimulate bodily functions when newborns. As pups grow, they return the favor, and the licking habit becomes embedded in how dogs relate to those they love.

So, when your dog licks you while you’re petting them, they may be treating you like part of their pack, offering grooming and bonding in return for affection. They won’t try to clean your ears (hopefully), but the impulse to care for their loved ones runs deep.

Seeking attention

Sometimes, licking is a smart strategy to demand more attention. Your dog learns quickly that licking gets a reaction. Maybe you laugh, pet them more, talk to them, or give them a treat (the jackpot in dog currency). While petting them, they may lick you to encourage you to keep giving them affection. Or, if they feel ignored, they may lick you to shift your focus to them.

Dogs are excellent social learners. If licking equals interaction, they’ll use it as a tool to get what they want.

Anxiety or stress relief

Licking can also be a self-soothing behavior. If your dog feels anxious, overwhelmed, or uncertain, they may lick as a calming mechanism. It helps them regulate their emotions; they settle themselves down through repetition.

You may notice your dog licking more in new environments, during storms, or after a stressful vet visit. If licking increases dramatically or seems compulsive, it could be a sign of underlying anxiety.

Taking in your scent

Your skin is a flavor-packed imprint on your dog. Pups have 300 million olfactory receptors (compared to our six million) and use licking to enhance their sensory experience. When you pet them, your scent transfers to their mouth, giving them more information about where you’ve been, what you’ve eaten, and how you’ve felt emotionally. Dogs can detect changes in your hormones and health through scent, so, if your dog licks you when you’re upset or sick, they may respond to subtle shifts in your emotions and wellness.

Training and managing licking behavior

While licks may be adorable or heart-melting, it’s OK if you don’t want to be turned into a salt lick whenever you show your dog some love. The good news is that you can manage this behavior without hurting their feelings or damaging your bond.

Positive reinforcement

The key to guiding your dog’s licking habit is to reward the behavior you want and dissuade the behavior you don’t. If your dog stops licking when you gently say “no lick” or redirect their attention, immediately praise them or offer a treat. Over time, they’ll learn that calm cuddles without the tongue will get the same warm reaction. It’s about reshaping their response without punishing their instincts.

Consistency is your best friend. Mixed signals, such as sometimes laughing or sometimes scolding in response to licking, will only confuse your pup, making training harder.

Setting boundaries

It’s OK to set gentle boundaries. Dogs thrive on clear communication. You can use verbal cues like “enough” or “good job,” paired with redirecting their attention to a toy or chew. Some pet parents train cues like “kiss” or “no kiss” to establish licking as an on-cue behavior rather than an all-the-time habit.

If your dog gets excessively enthusiastic during petting sessions, it may help to pause affection when the licking starts. You can resume pets and rubs once they settle. This helps reinforce that calm behavior earns more attention.

When should you seek professional help if the licking gets out of hand

There’s a point where licking becomes excessive, and if your dog won’t stop licking you or themselves, it could indicate an underlying issue, such as:

Call a veterinarian or certified dog behaviorist if licking escalates into a compulsion, disrupts your dog’s daily routine, or seems linked to distress. They can help rule out medical causes and guide you toward behavior modification techniques that protect your pup’s well-being.

Pro tip: Keep a behavior journal. Track when the licking happens, how long it lasts, and what’s happening around your dog. This can provide valuable clues for professionals.

Bottom line

When your dog licks you while you’re petting them, it’s usually a blend of affection, curiosity, comfort, and instinct. Think of it as their unique love language — messy, endearing, and sometimes over the top.

While most licking is normal, you can teach your pup when and how it’s appropriate. With gentle training and positive reinforcement, you’ll find the perfect balance of tail wags and kisses to connect you both.  

Next time you’re enjoying a snuggle and feel that familiar lick, smile. It means your canine loves and trusts you.
