Dogs sniff people—especially the groin—because their noses work like our eyes, helping them gather detailed information. The apocrine glands in that area release chemical signals about stress, hormones, health, and even where you’ve been. To dogs, it’s not inappropriate—it’s instinct.
Most of the time, sniffing is simple curiosity, but sudden or intense interest can occasionally reflect real changes in your body. Still, you can train dogs to greet politely with commands like sit and leave it, and by rewarding calm behavior. Redirecting them with scent games or cues helps set boundaries without punishing natural instincts. Remember, sniffing is a dog’s way of understanding and connecting with you—and sometimes noticing things you miss.
