Not all dog owners understand why their pets have such a genuine interest in human feet.
However, the animal has several logical arguments in favor of its strange habit.
Animals still live by the "ancient rules" that helped them survive in ancient times. The wild ancestors of dogs had to carefully get rid of the intense smell with their tongues.
This helped to avoid bringing trouble on yourself in the form of an aggressive predator. If the dog actively "washes" you, then it is trying to protect you from possible enemies.
Experts note that the tongue is a way for a dog to express its feelings and emotions towards its owner. It encounters this "ritual" in childhood, when the mother vigorously licks the puppies.
The dog then associates this gesture with love and care.
Sometimes a dog simply doesn't know how to attract the owner's attention. In this case, absolutely any methods can be used.
Therefore, it is worth devoting more of your time to your pet.
