Belly, or when the owner approaches, the dog takes the initiative to expose its belly, which is a sign of goodwill and a sign of sufficient trust; the second is not guarding the food: when the dog is unfamiliar, the dog will react because someone is approaching it. Toy or food, and growling and purring, this is actually a demonstration. Do not approach at this time. When the dog no longer protects the food, it completely treats you as one of its own. The third is to obey your instructions at any time. : Even at a relatively long distance, the dog can still respond quickly after hearing the owner's instructions, so it can basically be said to completely accept you.
