The dog turns over and exposes its belly, which is mainly a sign of goodwill, because the belly is the softest and most vulnerable part of the dog's body. Dogs will only behave like this in a safe and comfortable environment. Of course, sometimes because the temperature is too high, dogs can cool down more by turning their stomachs. Many times, we can see dogs sleeping in air-conditioned rooms, turning their stomachs unscrupulously and sticking out their tongues. If you see this phenomenon among stray dogs or local dogs, it may mean a kind of surrender and surrender. Whenever two dogs fight, one of them who loses will make this action.
