Anyone who has dogs knows that they like to lick their faces when they get home. To the delight of some and despair of others, the tongue is one of the main instruments by which dogs learn to interact with the environment.
The main reasons behind the ‘welcome greeting’ of our best friends:
Communication: A canine lick can be a sign of greeting to humans who have been away from home. It’s a way of saying: ‘hello’
Explore: Like smell, licking is a way in which you explore the world.
Hunger: It may be a sign that you want to eat. When this happens, he usually licks his mouth.
Attention request: Your dog wants to play or pamper you.
