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.
Antioxidants are chemicals that the body uses to combat free radicals. And free radicals are substances that might harm the body if they exceed a certain level. Antioxidants are also beneficial for your pets, especially your dogs. Your dog needs antioxidants to help promote a healthy immune system. Hence, every IAMS™ dog formula contains optimal levels of these nutrients.
Antioxidants are naturally occurring essential nutrients that help maintain your dog’s health by slowing the destructive oxidative process of cellular molecules. IAMS™ research has been focusing on advancing antioxidant nutrients for senior dogs — and the benefit is improved immune function. Discover how the antioxidants in IAMS™ products can benefit your dog’s health in a number of ways.
Antioxidants are found naturally in fruits and vegetables. Common antioxidants include vitamin A, vitamin C, vitamin E, and certain compounds called carotenoids (like lutein and beta-carotene). When antioxidants are a part of a dog’s complete diet, they can provide the following benefits:
As cells function normally in the body, they produce damaged molecules called free radicals. These free radicals are highly unstable and steal components from other cellular molecules such as fat, protein, or DNA, thereby spreading the damage.
This continues in a chain reaction, and causes cells to die. This process is called peroxidation. Peroxidation is useful because it helps the body destroy cells that have outlived their usefulness, and it kills germs and parasites. However, when left unchecked, peroxidation also destroys or damages healthy cells.
Antioxidants help prevent widespread cellular destruction by willingly donating components to stabilise free radicals. More importantly, antioxidants return to the surface of the cell to stabilise other cellular components.
When there are not enough antioxidants to hold peroxidation in check, free radicals begin damaging healthy cells, which can lead to problems. For example, free radical damage to immune cells can lead to an increased risk of infections.
Antioxidants offer countless benefits to our furry friends. And it is imperative that their food is loaded with it. Want to know why? Read on.
Antioxidants are a must for dogs as they are exposed to significantly more toxins than humans. These antioxidants work like protective agents within the dog’s body, battling free radicals that cause symptoms and diseases like skin problems.
Furthermore, giving liver antioxidants for dogs will boost liver health and eliminate toxins from their body more efficiently. The liver will convert fat-soluble toxins into water-soluble toxins to easily flush them from your pet’s body through the GI tract and kidneys.
Recent research has examined the benefits of certain antioxidants on the immune response of dogs, and the results of these studies indicated that antioxidants are important in helping dogs maintain a healthy immune system.
