Being a pet parent means more than just feeding and caring for your furry friend—it also means learning to understand their behavior and the way they communicate. One habit that often leaves people puzzled (and sometimes embarrassed) is when a dog sniffs someone’s private area.
Experts explain that this isn’t bad manners—it’s actually how dogs say hello and gather information. Humans have special scent glands, called apocrine glands, that release pheromones. These pheromones carry details about who we are, including things like age, mood, sex, and even health. While these glands are found in areas like the armpits and genitals, dogs usually head for the crotch simply because it’s the easiest spot for them to access.
For dogs, sniffing is the equivalent of shaking hands, exchanging names, or asking a few polite questions. Since they can’t communicate with words, their nose becomes their way of learning about the world and the people around them.
Of course, if you feel uncomfortable with this behavior, it can be redirected through gentle training. Using simple commands such as “sit” or “stay,” and rewarding your pup with treats, helps them learn new ways to greet people politely—while still respecting their natural instincts.
