If you have a pet dog, chances are you’re used to being licked by your furry friend several times a day.
From chasing their tails to eating unpleasant things, dogs have many habits and behaviors—some normal and others a bit gross. But licking is definitely one of the most common canine behaviors.
People often interpret licking as a dog’s way of showing affection. However, the meaning behind this behavior can actually vary from dog to dog.
According to pet expert and founder of Yappy.com, John Smith, there are four main reasons why dogs lick their owners.
Showing affection
Mother dogs often lick their puppies, which is why it’s believed that dogs have an instinct to lick as a way of expressing love.
It’s also thought that licking releases “feel-good” hormones in dogs, which helps calm them.
Pet expert John Smith explains:
“Whether your dog greets you with kisses when you come home or happily licks you throughout the day, most of the time licking is a sign of love and affection.”
Showing empathy
Another reason dogs lick is to understand your mood.
Dogs are extremely sensitive animals. They use licking as a sensory tool to figure out who you are and how you’re feeling. A dog’s tongue contains millions of sensory receptors, which helps them better understand new people.
If you appear upset, your dog may mirror that emotion and use licking as a way to comfort you.
Showing trust
Dogs also lick to gain your trust. This behavior shows that they consider you the leader of their pack.
John Smith says:
“For dogs, licking the pack leader is a natural behavior that dates back to when dogs were wolves in the wild. Wolves would lick their leader when reuniting to show obedience and loyalty.”
Tasting you
Sometimes, dogs lick you simply because they like the way you taste.
This could be due to leftover food flavors on your hands or face, or a subtle scent.
Studies have also shown that dogs’ tongues can taste salt, which may explain why they lick you when you’re sweating.
Is licking ever a sign of a problem?
It’s important to keep in mind that excessive licking can sometimes indicate that something isn’t right with your dog.
In some cases, licking can be a sign of nausea in dogs.
So, if your dog doesn’t usually lick you much but you notice a sudden change in behavior—especially if it’s accompanied by other signs of illness—it’s best to contact your veterinarian to be on the safe side.
