Any dog tries to show its owner (and sometimes not only him) signs of attention in the form of its "kisses".
Some people may find this habit annoying, as they fear that it is not the most hygienic procedure.
Others are quite tolerant of their pet's wishes.
People don't even like the smell of sweat, so we try to get rid of it at the slightest opportunity or at least mask it. Animals have a different opinion.
Not only are they delighted by the smell of their owner's sweat, but they also happily taste it.
Dogs don't have many options to express their feelings towards their owners, experts say. That's why kissing is usually a sign of love, sympathy and other positive emotions.
For the same reason, a dog may lick its relatives and other domestic animals.
From childhood, the puppy gets acquainted with the mother's language, which she uses to tidy up the babies. Therefore, for the dog, this becomes a sign of care.
Therefore, the dog can run up to you with his "caresses" at the moment when you look tired and depressed. In this way, the dog tries to cheer you up and put you in order.
