There’s no doubt that dogs are affectionate creatures. And they have numerous ways of showing it. One of these ways is by licking their owners. You may enjoy it when your furry friend comes up and gives you a big ol’ pooch smooch. But why do dogs lick you? In a poll* of dog owners, IAMS™ found a large majority (75%) believe dogs lick people to offer signs of friendliness. That’s definitely a correct assumption. Let’s dive a bit deeper for a better understanding.
Licking has been a social behavior among dogs since the days of the great-great-great granddaddy wolf. 'It’s a standard canine greeting to lick others around the face,” agrees James Serpell, B.S., Ph.D., Professor of Humane Ethics & Animal Welfare at the University of Pennsylvania School of Veterinary Medicine. “Junior members of the pack will run around and lick the mouths of more senior members.” But is that all that there is to dog licking behavior? Or are there more reasons why dogs lick people? Let’s find out!
Here are a few reasons that can explain why dogs like to lick.
For dogs, licking is equivalent to kissing or showing affection. You may have noticed female dogs licking their puppies which is a behavior that is intended to show affection. And your dog considers you part of their pack, so they show you affection the same way their kind does - by licking.
Dogs are oral creatures and gather a lot of information about their surroundings through taste and smell. Maybe you’re salty after a sweaty run. Maybe you’ve got barbecue sauce on your face. “Dogs can smell a lot better than we can,” says Dr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager, Global Science Advocacy at Waltham Petcare Science Institute, “so they find a lot more things interesting to lick than we can.” This is despite the fact that dogs only have about 1,700 taste buds compared to around 9,000 in humans.
Have you been too busy with work lately? Or has anything kept you inattentive toward your pooch? If so, it’s probably one of the reasons why your dog is licking you. It is also possible that your dog just got too bored and wants you to play with them, which is why they’re suddenly licking you.
That’s true. Much like humans, dogs can also suffer from obsessive-compulsive disorder, which can be concerning. It is often triggered due to stress and anxiety and makes the dogs suddenly begin licking. You will need to visit your vet if you suspect this to be the case.
Unlike humans, no other animals have knowledge about or access to proper healthcare. So, when they get injured, their first instinct is to lick their wounds. This helps them numb the pain to a certain extent, and also clean the wound. Thus, when your dog sees a wound on you, their natural instincts kick in and they try to help you by licking the wound, thinking it will clean the wound and lower the pain.
In fact, in ancient Greece, dogs at the shrine of Asclepius were trained to lick patients. In the Middle Ages, Saint Roch was said to have been cured of a plague of sores through his dog’s licking. The French even have a saying, “langue de chien, langue de médecin,” which translates to, “a dog’s tongue, a doctor’s tongue.”
Don’t cancel your health insurance just yet. While a dog’s saliva does have some possible bactericidal properties against some types of bacteria, it can put you at risk of exposure to others. Too much licking can also reopen the wound and cause further infection. With modern medicine, you’re much better off hitting the first-aid kit. And that myth about dogs’ mouths being cleaner than humans’? Not true — both contain over 600 types of bacteria.
While an occasional canine kiss is “aww”-inducing, some dogs can overdo it to the point of annoyance. When this happens, the best thing to do is “completely ignore it and give no attention,” suggests Dr. Jo Gale. “When they stop, provide them with attention.” This acts as a form of positive reinforcement. Over time your dog will learn to scale back on the smooches. Another thing you can try is training them to cut back on the licking. Remember to use positive reinforcement in this case too - reward them with treats or toys when they display good behavior.
Yes, but not always. For dogs, licking is also a way to explore and understand the world and the beings around them. Sometimes it can also be an indication of their OCD.
Your dog may be licking you because of either of these reasons - to show affection, to seek your attention, because they like how you taste, or because they are feeling stressed or anxious.
If a dog keeps licking constantly, it may be because they are feeling anxious or stressed. Sometimes these feelings also trigger OCD in dogs, which can make them lick obsessively. They may also do it when they are bored and want your attention.
Sometimes, dogs choose to show dominance via licking. They may do this with either other dogs of the pack or with humans. Dog licking may indicate dominance especially when the licks are uninvited, and the dog begins showing dominant behavior. This can include not obeying commands and acting in a demanding way.
A dog’s licking may indicate several things. They are either showing affection or are just bored and need your attention. They may also lick you if they think you taste good or interesting.
Obesity in dogs is a more common problem than you might think. Between 25% and 40% of dogs are overweight, but often, owners don’t realize it until they take their dog to the veterinarian for another reason. Yet even vets can’t tell if a dog is obese by their weight alone. Ideal weight varies by breed, and quite widely within breeds.(Did you know, for instance, that Labrador retrievers, dachshunds and beagles areall prone to obesity?) In short, there’s no ideal healthy weight chart for all dogs!
The good news is that if your dog is overweight, there are a number of ways to help them reach a healthy weight. Don’t underestimate the power of daily walks and a weight management dog diet — IAMS™ Adult Healthy Weight can help return your dog to a healthy weight, providing a path to help keep them fit for life.

Can you feel individual ribs easily? Is your dog’s abdomen slightly tucked up whenviewed from the side? That’s a sign your dog is at their ideal weight.
If you can't feel the ribs easily, your dog has no waist and their abdomen drags,your pup is carrying extra weight. Your veterinarian can help you further evaluateyour dog’s condition and determine their ideal weight.
Dogs gain weight for the same reason people do: They eat more calories than theyuse. Today’s dogs share another problem with their human parents: lack of activity.Many pet parents work all day and are too tired to play with their dog afterward.
Dogs’ metabolisms might slow as they age or after they’re spayed or neutered,which means they require less food. Another common reason for weight gain isfrequently eating high-calorie treats. Sometimes more than one family member isfeeding the dog, and the dog sure isn’t telling!
Other factors that could contribute to canine obesity include:
If you suspect that your dog is overweight or obese, the !rst step is to set up anappointment with your veterinarian so they can evaluate their condition. Likewise,before beginning any weight loss program with your dog, make sure to discuss itwith your vet.
If your dog is overweight, it’s time to implement a weight-management regimen. Ifyou usually feed one large meal a day or keep food available at all times, try adifferent dog-feeding schedule by dividing the daily ration into several small meals— at least two meals a day. It takes energy to digest food, and dividing your dog’sdaily ration into separate feedings will help. If your dog leaves any food in theirbowl, pick it up 30 minutes after each meal.

Your goal is to help your dog be healthier, so select their food carefully. Payattention to the ratio of fat, !ber, protein, carbohydrates and special ingredients inyour dog’s weight-management food:
After your dog reaches their ideal weight, select a maintenance food to keep theirweight steady.
