Dogs perceive the world primarily through scent, using their noses to gather detailed information in a way humans cannot imagine. While people rely on sight and language to form impressions, dogs interpret identity, emotion, and health through smell. Their instinctive behavior, such as sniffing a personās crotch, can feel awkward to humans but is entirely natural for them. The apocrine glands in those areas release pheromones that communicate biological data, offering dogs a quick and authentic introduction. For them, this is simply a polite way to understand who someone is and how they are feeling in that moment.
