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 behaviour 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 behaviour? 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 behaviour 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 behaviour. 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.
Just like in humans, obesity can lead to serious health issues in dogs as well. The primary causes of obesity in dogs are lack of physical activities, imbalanced diet, and overfeeding. If you notice a sudden increase in your dog’s weight despite having a normal diet and sufficient exercise, it could also be a sign of some hormonal disorder. Obese dogs are at risk of developing diabetes, heart diseases, bone deterioration, arthritis, and other severe disorders. Thus, it is crucial to monitor your dog’s weight.
Wondering what is the ideal weight for dogs? A dog’s healthy weight can differ from breed to breed; hence, you can consult your vet to understand the right weight range for your pet. However, the below dog weight chart will help you get an idea on whether your furry friend is underweight, healthy, or obese.

You can clearly see an underweight dog’s ribs, spine, and hip bone. There is zero body fat and that can be seen on its body. In dogs who are genetically thin, the loss of muscle mass may be evident.
You can easily feel the ribs, spine and hips of a dog that falls in an ideal weight category. Its waist should also be visible from above and the side. The last couple of ribs may be visible on a short-coated dog while playing or exercising, which is normal.
A dog is considered overweight when it weighs 10-20% more than its ideal body weight. It is difficult to feel the ribs of these dogs. The fat accumulation is also visible at the base of its tail and on the belly. Its back also starts to appear broader. It is advisable to start working on shedding the extra kilos your dog has gained at this stage.
A dog is considered overweight when it weighs 20% more than its ideal weight. You cannot feel its ribs at all due to the heavy fat accumulation. Fat deposits are also visible around the dog’s neck and its belly also starts to droop.
You can measure your dog’s weight at home if your dog is a small breed. Here are the steps to follow while measuring the weight of your dog at home:
Step 1: Stand on the weighing scale and take note of your weight
These steps should not be followed by those who have medium or large breed dogs. The size of your dog could make it difficult for you to hold it properly, and if it starts fidgeting, the handler or the dog could get injured. Hence, owners of medium and large breed dogs should go to the vet to weigh their pet.
You can easily manage your dog’s obesity and maintain the ideal weight of your dog if you follow a regime and take the necessary steps. Here’s are some things you should keep in mind during your dog’s weight management:
Dogs remain healthy if their food quantity is controlled and they are fed on time. But you should avoid feeding your dog home-cooked food. Wondering why? It is because home-cooked meals might not have the right nutrients in the right quantities and that can later affect your furry friend’s overall health. Hence, to keep such risks at bay, it is best that you avoid feeding home-cooked food. In case you plan on giving your dog home-cooked meals, it is imperative that you follow the recipe to the T.
Your dog is your friend so, it's hard not to share your delicious bacon or a mouthful of steak with it. When your dog sits next to you and makes those adorable puppy-dog eyes as you eat, it becomes even more difficult to not share some of your food with it. But you must resist. Giving “human food” greatly increases your dog’s fat intake. It also conditions the dog to believe that it will be fed every time you eat.
Exercise is a great way to keep your dog in shape. If you have a busy schedule, then you could break it down into short sessions to play fun games like tug-of-war or go for a quick jog with your dog. You could also play with a frisbee or start working on its agility. Dogs that get enough exercise are less likely to be stressed and this way, you would also get a break from your work.
Of course, you want to reward a dog when it’s been a good boy or a good girl. But keep in mind that those dog treats can add calories and fat. And more importantly, think about how many types of treats and snacks you are feeding your dog and how often.
Most of the time, dogs are overweight because they are taking in more calories than they burn. But it's possible there's a bigger problem. If you've tried to control your dog's diet and increase exercise and haven't seen any results yet, consult your veterinarian about thyroid disease or other metabolic or hormonal disorders.
Don't feel discouraged if you don't see results right away. The fight against obesity is fought one day at a time. It is the inculcation of good habits and discipline. By following the tips above and increasing your willpower and patience your dog’s weight management will be an easier and healthy process.
There are lots of dog foods available in the market and each pack contains different quantities of proteins, vitamins, minerals, and other nutrients. You must go for foods that provide complete nutrition to your furry friend, and not just calories. Hence, it is necessary to opt for a pet food brand that specialises in dog nutrition.
