What's actually happening is stranger, and far more useful to you. There's a study where a dog turned down free food because of something that person had done to their owner. There's one suggesting dogs can tell the difference between someone who is wrong and someone who is lying. And there's one from last year that found absolutely nothing at all — I'll tell you about that one too, because I'd rather you trust me than be impressed by me.
