There are several explanations for why your dog is licking you. The main reasons for such actions are the desire to say hello to you and attract your attention.
But that’s not all. Licking as an instinct is associated with the behavior of the puppy mother. Puppies are accustomed to licking to greet their mothers and ask for food. The mother then vomits the material that the cub can eat.
However, human licking for adult dogs is primarily a form of greeting.
In addition, dogs show this behavior only towards humans. Experts believe this is due to the person being the guardian of the dog. As a result, in a sense, a dog that lives with its owner will behave with that person all his life in a similar way to his mother. This behavior is seen in other pets: cats, for example.
