Why does my dog lick me so much? There are actually several reasons

It might be more than to give you slobbery kisses

If you’ve ever been around a dog, you’ve likely been on the receiving end of a lick or two. Traditionally, people associate licks with kisses. However, if your dog is constantly slobbering all over you, you may wonder: Why does my dog lick me so much? Is something wrong?

Also, there’s a totally untrue rumor that dogs don’t love us but merely use us for food. That said, the idea that a dog’s licks are also a sign of affection is also something of a myth. Your dog may have other motives for treating you like their personal ice cream cone. Some are as sweet as your favorite frozen novelty, while one may leave a saltier taste in your pup’s mouth. Here are several reasons why your dog licks you, plus when to be concerned and how to curb the behavior if you want.

Why does my dog lick me so much?

Dogs lick their favorite humans for various reasons, including instincts and affection, and to flag feelings of physical or mental distress. Understanding what causes a dog to lick you so much can help you determine which one applies to your pet and get them help if necessary.


Dogs used licking for various reasons before becoming the domesticated companion animals we know and love. Mother dogs lick to groom and comfort their new puppies and even encourage them to use the potty. Additionally, baby wolves, foxes, and coyotes will lick their mother when she returns from hunting to get her to throw up her food for them to eat (Gross? Yes. Natural and life-sustaining? Also, yes.)

While your dog is domesticated — and may be spayed and neutered — they may still have this innate desire to lick you to clean you off, comfort you, or perhaps get you to lose your lunch for their benefit (no need to oblige).


The rumors might be true — some dogs lick for a similar reason that you may kiss a loved one (four-legged or two-legged) — to show love. While dogs once licked for food and grooming purposes, the behavior has evolved, just like dogs themselves (and our relationship to them).

Some dogs may lick you to let you know they’re thrilled you’re home from your 30-minute-going-on-five-year adventure to the grocery store. Others may snuggle up to you and lick you a few times while you watch Netflix to bond. Soak up those puppy kisses, regardless of your furry friend’s age.


Are you down in the dumps after a stressful day at the office? Don’t be surprised if your dog showers you with licks. Your pet may be a better reader of your state of mind than a mood ring. If your pup senses something is off, they may start licking you to display empathy. This instinct may be inherited since mother dogs lick their puppies to comfort them during their first weeks.

You’re delicious

Aside from the instinctual drive to get you to regurgitate your food, dogs may lick their humans because they taste good. For instance, some dogs are particularly keen on licking people who recently exercised. The salty taste of sweat may be one of their favorites.

While dogs have a legendary sense of smell far greater than a person’s (especially some breeds like beagles), they have fewer taste buds than we do. We have five times more taste buds than dogs. In other words, our sense of taste is stronger. That doesn’t mean dogs can’t taste, though, or enjoy the delicacy that is your post-workout sweat.


Dogs thrive on positive reinforcement. If you have habitually praised or snuggled them when they lick you, you encourage them to continue. Your dog may engage in a slobber fest if they want your attention and comfort, such as a belly rub (or treat).

On the flip side, excessive licking can be your dog’s way of letting you know they need attention for other reasons. Your dog may be sick, and chronic licking is also a red flag for stress. Is your dog showing other signs of illness, like lethargy or a dry nose? A vet trip may be in order. Did they undergo a significant life change, like a new baby or move? They may need some TLC and time to adjust.

When (and how) to do something about dog licking

Generally, dog licking is instinctual, habitual, or a sign of affection. However, if you suspect your dog is sick or stressed, call the vet. They can help you find solutions and treatments. Also, you may not enjoy constant tongue showers. In those cases, some ways to curb the behavior include:

  • Redirecting the dog’s attention when they go in for a lick to a toy
  • Purchasing lick pads
  • Treating the dog for focusing on or licking something else or refraining from licking you
  • Ensuring your dog is getting plenty of enrichment and comfort through toys, exercise, and physical touch as desired throughout the day

A trainer may also be able to help you with some of these strategies.

Closing thoughts

Dogs lick people for various reasons. While kissing is traditionally associated with licking — and affection is one reason — dogs may instinctually give you a tongue bath. Throughout time, dogs have licked their puppies for comfort and grooming, and small dogs lick adult ones that return from a hunt to get them to throw up food so they can eat.

Sometimes, dogs may lick because they are feeling sick or stressed. Generally, licking is natural and nothing to be concerned about. However, a vet or trainer can help you determine why your dog is licking and curb the behavior (or treat any applicable illness).

Does your dog like to lean on you? Here’s why
The sweet reason your dog likes to lean on you (and when to be concerned)

Our attitude toward dogs has shifted significantly in modern times, with humans considering their pets more like family members that they love just as much (or more) than their two-legged relatives. However, we have long been partners with canines, which have helped us hunt for food and protected us with our lives. This long-running partnership comes even though we don't speak the same language.

Therefore, you may wonder what is going on in your dog's head when they display certain behaviors. For instance, you may ask, "Why does my dog lean on me?" The answer is generally straightforward and sweet. However, a dog leaning on you may be a cause for concern, too.

Most of us have suffered from a bout of the hiccups at least once, and while hiccuping can be annoying, it's very rarely harmful. However, in some cases, hiccups can be a symptom of an underlying medical problem, such as pneumonia or pancreatitis. In very rare cases, hepatitis or liver cancer may cause hiccups.

This sounds scary, but does that mean you should be worried if your dog has hiccups? More often than not, your dog's hiccups will resolve within a few hours, but if your pooch has difficulty eating, drinking, or sleeping because of his hiccups, it's a good idea to take him to the vet. Here's what you'll want to know about canine hiccups.

Why do dogs howl at sirens? This exhausting behavior, explained
Plus, how to correct this behavior with positive reinforcement
Small dog howls at the sky while outside in the dirt

While your beloved pup's ancient ancestors may have howled at the moon, there's nothing more annoying than being jerked awake by your dog barking at a siren. As much as you might immediately jump in and try to correct the behavior, remember that this response is rooted deep within a canine's DNA. They might not fully be able to help it, though positive reinforcement training can temper these responses. So why do dogs howl at sirens? We'll dive into this phenomenon.
The history of the howl

Wolves may have been howling for millennia and have lived in North America for at least 15,000 years. When dogs evolved about 30,000 years ago, by some estimates, they took the howl with them. This practice almost certainly began as a way to communicate with others of the pack over long distances and occasionally to scare away predators or even other wolves.
