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.
As a pet parent, do you find yourself wondering how long does dog food last? If so, you’re not alone! In this blog, we will take you through everything you need to know about dog food expiry.
Dogs require a balanced meal every day. As a pet owner, you can choose between dry and wet foods. Dry dog food usually resembles a biscuit or kibble. On the other hand, wet dog food combines meat products or other protein sources with a gravy that incorporates grains, minerals, and vitamins. Whatever your dog finds palatable, make sure their nutritional requirements are met.
Diets that are high in protein are good for dogs. A significant source of energy is found in dietary fats, which are either derived from plant seed oils or animal fats. They offer essential fatty acids, like omega-3s, that are necessary to preserve the health of your dog's skin and coat. Additionally, carbohydrates support your pet's digestive health and provide energy for them to continue with their regular activities.
While it is important to focus on your pet’s daily nutritional intake, you should also make sure that the food packets are still fresh. Serving expired dog food will deprive your canine companion of the key vitamins and minerals they need to keep healthy. Hence, it is important to examine the labels and expiration dates before making a purchase. This way you will be able to understand how long you can keep dog food fresh.
The amount of time a product is useable and suitable for consumption is referred to as its shelf life. In contrast, expiry date is the last day that a perishable product, like food, will be at its highest quality.
If you are wondering does dog food expire, the answer is a yes. In fact, the contents and types of preservatives used do affect the shelf life of a food item. So, to guarantee your dog's safety, pet food producers set expiration or best by dates. Unopened canned foods have a shelf life of two years from the date of manufacturing, whereas unopened dry pet foods typically have a shelf life of 12 to 18 months. Plan to open and use the dog food before the expiration date. You can usually find this date on the bottom of the can containing dog food.
Now that you know dog food expires, let’s examine the effects of serving expired food to your pet:
After consuming spoiled food, dogs generally exhibit the same gastrointestinal symptoms as people do. These symptoms could include vomiting, diarrhea, and passing wind. Spoiled foods can also contain bacteria that can disturb the equilibrium in the gut and intestines, causing the body to excrete more fluids in an effort to wash them out. What’s more is that moldy dog food can contain mycotoxins like vomitoxin, which can cause serious gastrointestinal disorders.
Dogs can become paralyzed from botulism. It is a rare condition occurring when canines consume contaminated food. The poison gets absorbed in the intestines and passes into the bloodstream, thus paralyzing dogs.
Another consequence of feeding your pet spoiled dog food is malnutrition. Before turning moldy, spoiled foods usually lose their vitamin and mineral value. This suggests that even if the food doesn't upset your dog's stomach, it is still not giving your pet what they require. Your dog may become lethargic if daily nutritional demands aren't met. This can eventually result in bone issues and organ failure, if not recognized as early as possible.
Even if you have a food item that is still within its best by date, improper storage could lead to early contamination and food degradation. Here are some steps you must take to prolong the shelf life and maintain food quality:
Purchasing multiple boxes of treats may save you from making repeat visits to the shop. However, keeping so much stock might increase the likelihood that your dog's food goes bad before it gets completely consumed. Therefore, shop frequently if you don’t want your dog’s food to expire.
The shelf life of fresh, wet items can be increased by keeping them in the freezer. Any unopened canned food should be sealed with plastic wrap and stored in the refrigerator.
Dog food that has expired needs to be tossed out right away. There are also waste management facilities that compost used pet food.
