Why do dogs lick you?

There are a number of reasons why your dog might lick you. It could be a sign of affection, a way to alleviate stress, or even a sign to show they are in pain.

Licking is a completely normal and natural behaviour for dogs. For them, it’s a way of bonding with one another, and with you. They do it to groom themselves, and it’s also a way for them to gather information. It's a habit they would have learnt in their first few days as a puppy, when their mother would have licked them to keep them clean and to provide comfort.

Why do dogs lick you?

Here are the main reasons why your dog might start licking you:

To say hello

As much as we might wish that dogs could speak, they can't, so licking you in the morning or when you return home from work may be a sign of greeting you. It could be their way of saying hello, and that they are happy to see you again.

It also helps our dogs find out what we’ve been up t through scent and taste – it’s a bit like them asking you how your day has been.

Attention seeking

If your dog licks you, you’ll probably start to make a fuss over them, whether that’s through stroking them, talking to them or even starting to play with them. This will encourage them to lick you even more as they will associate it with positive actions. Even if you don’t like the licking and actually tell them off, they’re still getting your attention.

We smell and taste good

Dogs’ senses are far stronger than ours and they can smell and taste everything, including sweat from exercising, food on our hands after eating, or lotion on our faces after moisturising. Licking makes a dog’s already amazing sense of smell even better, so you may find your dog giving you a good sniff and following it up with a lick.

They’re stressed or anxious

Licking can also be a soothing behaviour for our dogs, helping them feel more at ease. If they’re stressed or anxious, licking you – or each other, or themselves – might help alleviate that worry. They also might lick you as a distraction when they’re unsure what to do – it gives them some time to decide while also telling you that they’re not entirely happy.

When should I worry about my dog’s licking?

As with any new behaviour, if your dog has suddenly started licking you, or themselves, a lot more than usual, then you should book an appointment with your vet. Obsessive licking that is difficult to stop could be a sign that they are anxious, or suggest that there is something wrong.

Dogs will lick someone to let them know that they’re not a threat, so if your dog is licking a person excessively it may mean that they aren’t comfortable and may be trying to comfort themselves, find out more information, or be asking the person to move away.

Make sure your dog can’t lick any areas where you have applied prescription ointments, as the ingredients may be toxic when ingested.

If your dog is constantly licking a specific area of their body, they may be uncomfortable, or itchy, or even in pain. Dogs will lick at a sore spot, but they may also use licking to distract themselves from discomfort elsewhere in their body. Dogs can sometimes lick themselves so much they irritate and damage their skin, so it’s worth keeping an eye on and getting it checked if you are worried.
