Korean normally call their dogs to them by gesturing with their palms facing up or toward the dog so when calling or gesturing for someone to come to you, don’t appear rude by calling them like that. You might be accustomed to doing this and it may seem nothing to you, but it can possibly offend someone. Instead, try flipping your hand towards yourself before making the gesture.
