Yes, I do think it's silly, because we aren't in their heads. I don't know what my dog thinks I am, besides Food-God and Door-God, and "she who we must obey". Pack animals, and herd animals, understand the concept of young, and normal well-balanced dog brains do not go after children as prey, but rather see them as small, sometimes annoying parts of the family, that they either see as something to protect, or as competition for affection, depending on their temperament.
