It is normal for a dog to start licking you every time you start showing affection towards it. For instance, you have just finished exercising and feeding the dog, then you start petting it and the dog starts licking you. At first, the licking may be minimal and you are just okay with it, but with time it intensifies and the dog will start licking all over your face. Some people may be content with this, but why do dogs lick?

This may be caused by traces of food on your skin or just the taste of salt and scents on your skin. In other cases, a new scent on your skin can also compel the dog to sniff and lick you. This will give the dog a lot of information regarding where you have been.


To attract attention

In other cases, dogs will lick people to attract attention. There are many ways through which a dog can attract your attention, including a tap using its paw, a nose nudge and barking. But if the dog has noticed that you do not pay attention to these attempts, it may result into licking. To seek attention, a dog will lick your arm, hand or your face. If your dog starts licking you, you should try to establish whether he is trying to tell you something. For instance, the dog may be trying to tell you that he needs a potty break, the water bowl is empty or that he wants to play because he is bored.

Additionally, when nervous, a dog will smack its lips or lick to calm its nerves and show other dogs around that it is not a threat to them.


When hungry
