Dogs have some unique ways of greeting each other, and one that often makes humans squirm is sniffing rear ends. But when that curiosity shifts to your crotch, things can get downright awkward.
So why do dogs do this? The answer lies in their powerful sense of smell. With over 220 million scent receptors—compared to our 5 million—dogs experience the world primarily through their noses. For them, sniffing is a way of gathering vital information. Crotches, in particular, carry strong odors from apocrine sweat glands, which give off distinctive scents dogs find fascinating. Since this area is easy to reach for medium and large dogs, it becomes a natural target.
Veterinarian Dr. Jennifer Sperry explains that dogs are simply following their instincts, not trying to embarrass you. Still, it can be uncomfortable for guests. The best solution isn’t punishment but redirection. Engage your dog’s nose with alternatives like snuffle mats, puzzle toys, or nosework activities. Teaching polite greetings, like “sit” or even a high-five, also works wonders.
In the end, crotch-sniffing is normal canine behavior. With positive reinforcement, you can channel it into friendlier, less awkward habits.
