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.
When deciding which pet food is right for your pet, consider these three factors:
Puppies should be fed three times a day from weaning (3 to 6 weeks) to 4 months of age. After 4 months, they should be fed twice a day. Most dogs should continue to be fed twice a day throughout their life, although some pets do well with one feeding.
The answer to this question depends on your dog’s age, size, and activity level. Feeding guidelines, which list the daily-recommended portion, are included on all IAMS™ packages. Start feeding your dog with this amount and adjust according to its needs. Remember to divide the portion accordingly if you feed more than once a day.
The amount you need to feed your puppy depends on 3 main factors — breed, weight, and age. However, you can take a look at this general guideline that we recommend for puppies:
Puppy | Adult Target Weight (KG) | Recommended Daily Feeding (g/day) | ||||
<3 months 3-6 months 6-9 months 9-12 months 12-18 months | ||||||
Toy breed | 1-3 | 15-72 | 32-83 | 37-83 | ||
3-5 | 33-106 | 72-121 | 83-121 | |||
Small breed (25-50) | 5-8 | 48-151 | 106-172 | 111-172 | 111-170 | Transition to IAMSTMPROACTIVE HEALTHTM ADULT DOG |
8-10 | 69-178 | 151-204 | 170-204 | 170-201 | ||
Medium breed | 10-20 | 82-299 | 178-343 | 201-343 | 201-339 | |
20-25 | 137-346 | 339-404 | 339-404 | 339-404 | ||
Large breed | 25-40 | 136-492 | 346-575 | 404-575 | 396-575 | 396-563 |
40-50 | 191-509 | 493-675 | 575-681 | 563-681 | 553-676 |
This diet contains 390 kilocalories of metabolizable energy (ME) per 100 gms. Remember to have clean, fresh water available for your dog at all times.
You should not change your puppy’s food to adult abruptly. Giving your pet time to acclimatise to the new taste of adult food is very important. Also, if you suddenly switch your pup’s food, it can cause digestive problems. Go through this schedule that will help you understand how much to feed your dog and transition your dog’s diet from puppy food to adult food:
If you are wondering how much to feed your puppy by weight and age, check out the weight and age-wise breakdown on when to transition your puppy’s diet to adult food:
Weight range | Age to begin transition |
Small breeds that weigh < 9.07 kgs | 9 and 12 months of age |
Medium breeds that weigh between 9.07 and 22.6 kgs | 12 to 14months of age |
Large breeds that weigh more than 22.6 kgs | 12 to 24 months of age |
While transitioning from adult dog food to senior dog food, it is important to factor in your dog’s weight. Take a look at this weight table to know when to transition your dog’s food from adult to senior:
Weight Range | Age to Begin Transition |
More than 90 lbs | 5 years |
51 to 90 lbs | 6 years |
21 to 50 lbs | 7 years |
Up to 20 lbs | 7 years |
When changing your dog’s diet, it’s important to slowly introduce new food. Start by offering your dog’s daily portion in a ratio of 25% new food to 75% current food. During the next three days, gradually increase the amount of new food and decrease the amount of the old food.
If your dog has gained unhealthy weight, make sure to cut down on fats along with increasing regular exercise. We recommend you browse through IAMS™ products and choose dog foods that are low on fat. How much food to feed your dog if they are overweight, is another major concern. You can consult your vet to understand the right amount of food your furry friend needs for each meal.
It’s important to understand that your dog’s nutritional needs change during pregnancy and ensure you feed her nutrition-rich food. For pregnant dogs, we recommend IAMS™ Puppy food as it’s full of proteins that can help your pregnant dog during the gestation period and improve the quality of milk to nourish her puppies post-delivery.
Wet food is an excellent treat that can be fed alone or mixed with dry food. Although IAMS wet dog foods are nutritionally complete and balanced, it is not necessary to offer wet food at every feeding. Our dry foods are formulated with high-quality protein sources such as chicken, lamb or fish, and contain all the essential nutrients pets need. The crunchy texture of dry food also promotes healthy teeth and gums, and aids in overall good oral hygiene. In addition, some of our dry dog foods contain a dental enhancement to help block tartar buildup on teeth during and after meals.

No. Unlike humans, dogs have fewer taste receptors. Hence, they won’t feel the urge to eat something different every day. In fact, if you find something that suits your dog’s overall health and preferences, stick to that food.
Soaking dry food will ease up the initial job of the digestive enzymes. While water will not change its nutritional value, the food should be eaten relatively soon. Moreover, ensure that the leftover portion is discarded to avoid spoilage. We recommend providing your dog with IAMS™ dry food because it is beneficial to your dog’s dental health as well..
No. Cats and dogs have different nutritional requirements. Moreover, cat foods are made with higher fat levels, which can be harmful to a dog. While it is okay for dogs and cats to sniff and lick some food from each other’s bowl, you shouldn’t let dogs eat cat food.
We recommend feeding your dog approximately two to four small biscuits per cup of food. Keep in mind that when you add biscuits to your dog’s daily diet, this increases its daily calorie intake, so you should reduce the amount of food you feed. Check the calorie content of the biscuit since biscuits vary in size and formulation.
Since IAMS™ dog foods are nutritionally complete and balanced, adding more vitamins, minerals or oils can disrupt the balance our dog food provides. The reason why you provide your dog with a high-quality product is that it has been developed to offer nourishment in proper ratios and ensure optimal nutrition. Hence, nothing needs to be added
Protein is one of the essential elements that should be a part of your dog’s diet. Including protein in your dog’s diet will strengthen its muscles, ligaments, and cartilages. A protein-rich food also brings about a healthy shine to your dog’s coat!
It is important to maintain a feeding schedule for dogs so that they are conditioned to expect food at that time and avoid irregular snacking in between.
You should never feed your dog home-baked goods, candy, gum, chocolate, limes, onion, and grapes. They can harm your dog’s digestive tract and cause infections as well.
IAMS™ dog food is full of key nutrients that your dog needs for its healthy growth. The basic ingredients in our food include chicken, fish oil, beet pulp, wholesome grains, and natural prebiotic.
