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.
Even if a pet food is formulated to provide all of the essential nutrients required by a dog, it is of little value if the animal will not eat it. Quality pet foods are carefully formulated not only to be highly nutritious but also to be highly palatable.
Highly palatable dog food recipes contain various ingredients and raw materials, including palatants. Palatants help improve the smell, flavor, and texture of your dog’s food. Examples of palatants include fat, salt, proteins, yeasts, and other flavors that are added to make food taste better. Dry foods usually need extra palatants to make them more pleasant and appealing.
Palatability is a term used to describe how well a dog likes the taste, smell, and texture of a food. A premium dog-food manufacturer spends a considerable amount of time conducting controlled feeding studies to determine the right combination of ingredients and processing techniques to produce a nutritious, palatable food.
There are two ways to test and measure the palatability of a dog food:
First Bite: The first palatability test is called the “first bite” preference. This measures the dog's first impression of a food's aroma and appearance.
Total Volume: Because the novelty of a new diet can cause highs and lows in first-bite tests, a second test is conducted called “total volume” measurement. Total volume determines the staying power or ability of a diet to maintain the animal's interest over time. This is the dog’s overall choice of a food based on taste, texture, and nutrition for the entire test period.
Dogs can become picky eaters for a variety of reasons. Some of the reasons why dogs can become picky eaters include:
In comparison to humans, dogs have significantly more smell sensors than taste receptors. This implies that foods with stronger aromas tend to appeal to dogs more. While scent is crucial, less odorous meals like dry kibble can also improve your dog’s food palatability. A dog’s taste buds are hard-wired to sense the presence of fats as well as salt (but not necessarily salt flavor). Fat is frequently added to kibble to improve flavor and palatability without making the food stinky.
While taste and scent are some of the primary ways a dog decides if something is pleasant, palatability can also be influenced by a wide range of factors, such as the dog’s unique preferences and even the owner’s preference for meals and feeding times.
To make a dog eat food, you need to:
Everybody in the household needs to accept and follow the pet’s feeding plan from the beginning. You should be consistent and rigorously adhere to your dog's diet. If you decide to give your dog leftovers, choose to combine nutritious foods with kibble.
Offering your dog table scraps often promotes begging and throws off your pet’s diet. It can also lead to several health issues, including diarrhea and pancreatitis. Although human food is far more palatable, it is less healthy than canned or dry dog food.
Puppies need to be fed two to three times a day, or as your vet may prescribe. As they get older, you can gradually increase the serving size while offering meals just once or twice a week. Additionally, you must add some variety and deliver equal servings.

In order to obtain and interpret accurate results, palatability studies must be performed by experienced animal technicians and the data analyzed by research nutritionists. Feeding studies are conducted by offering an animal two bowls of food at the same time. Each bowl contains a different diet that has been carefully weighed and recorded.
The technician observes which food the dog chooses to eat first, and then records that as the first-bite preference. After a specific time period, bowls are removed, and any remaining food is weighed and recorded. Diets also are switched from left to right each day of the study to ensure that dogs are not eating one diet simply out of habit.
The total-volume measurement is determined by calculating the difference between the beginning and ending weights of each food. This procedure is repeated using the same two diets with the same group of dogs for five days. At the end of the five-day study, all observations and data are compiled and analyzed to determine the overall palatability of each diet.
Here is a quick look at some flavors that can appeal to your pet.
Meaty Flavor
Animal Fats
Gravy or Stews
Dogs are attracted by not only the taste of a food, but also to its sight, aroma, and texture. Dogs are particularly interested in the smell of food.
If you are wondering how to increase palatability of dog food, here are a few tips that might help.
Whether your pooch prefers dry or wet dog food, remember that the choice of protein is extremely essential. The most palatable dog foods are ones that are available in different meaty flavors such as lamb, beef, and chicken.
By adding fats, salts, and other additives, dry dog foods are made more palatable. Additionally, fats contribute a softer taste to the food which dogs tend to enjoy. In fact, canines find fats to be tasty and will actively seek this flavor in their meals. While the aim is to serve highly palatable dog food to your pet, do be sure to check the right amount of fat content with the veterinarian./p>
Another strategy for improving the taste of food is to add food additives. These can be actual meats that the dog owner adds to the dish such as boiled turkey or any flavored store-bought gravies.
Since many supplements aim to increase the nutritional value of food, they may include ingredients that are disliked by dogs. Try introducing liquid or soft treats to make dog food more palatable. There are also certain supplements which are tasty by nature. These can be used to enhance the flavor of dog food while maintaining nutritional value.
Liquid digest is simply protein that is enzymatically broken down into amino acids, which are the building blocks of protein. The enzymatic process reduces large protein pieces to smaller protein pieces and free amino acids. By adding small amounts of acid, the enzymatic or digestive reaction is stopped, and a stable liquid ingredient is produced. After a dry-food formula is cooked, formed into kibbles, and dried, the liquid digest is sprayed evenly on the outside of the dry kibbles. This is called “enrobing.” Not only does the liquid digest make the food highly palatable, but it also adds to the overall digestibility of the food.
Yes. We use liquid digest made from chicken to enhance the palatability of dry foods and to contribute to the nutritional value of the diet. Some pet foods include flavor enhancers, such as onion powder, which simply mask the aroma and taste of the ingredients and provide no nutritional benefits to the animal.
