Dogs have a way of greeting each other that you might find a little awkward: sniffing each other’s butts. But when your furry friend turns his attention to your crotch, it can be downright awkward. But why does he do it?
Anyone who has ever owned a dog will be familiar with the fact that dogs communicate and greet others in a variety of ways, and their sense of smell plays a key role. Dogs explore the world through their noses, and their sniffing habits are how they gather important information.
A dog’s superior sense of smell comes from the 220 million scent receptors in its nose. That’s about 50 times more than humans have, giving dogs the ability to detect odors that are completely undetectable to us.
Simply put, dogs are incredibly curious creatures and have a keen sense of smell that helps them gather information about you.

Dogs are attracted to strong scents, Jennifer Sperry , a veterinarian with Pets Plus Us Insurance, tells Rover.com. Crotches, with their sweat glands and unique aroma, are like a welcome mat for a dog’s nose.
Fortunately, there are ways to guide your dog’s curiosity toward a more polite greeting. Read on to find out why dogs sniff your crotch and how you can redirect this behavior.
Why does my dog sniff my crotch?
Have you ever wondered why your dog can’t resist sniffing your crotch? According to Rover, there are some key reasons behind this behavior that might surprise you.
First of all, the height is ideal for sniffing! At least for medium and large dogs. But it’s not just about comfort; the crotch also has a unique feature that makes it a hot spot for dogs.
The area is home to apocrine sweat glands, which produce a stronger, more pungent odor than those found elsewhere on the body. Although these glands are also found in places like the armpits and chest, your dog’s nose may not be able to reach them.
Additionally, Dr. Sperry points out that dogs tend to focus on the crotch because it’s a more noticeable source of scent compared to other areas, like the hands or feet. So the next time your pup gets overly friendly, remember that it’s all due to their keen sense of smell.
Preventing dogs from sniffing crotches
We know that dogs are curious creatures, and when your dog greets a guest by sniffing their crotch, they’re just trying to gather information about them.
But let’s face it, no one wants a dog’s wet nose in an uncomfortable place. But how can you curb this behavior in a way that’s both effective and kind to your furry friend?
1. Redirect, don’t discipline
It can be tempting to scold your dog when they become too friendly with a guest, but that can backfire. Dogs don’t really understand why you’re upset, and it can cause confusion and stress. Instead, try redirecting your dog’s sniffing habits toward more appropriate outlets, such as sniff mats, toys, or food.
If you give your dog an outlet to satisfy his olfactory instincts, he’ll be less likely to focus on your guests’ intimate areas.
2. Teach him a new trick
A great way to keep your dog from sniffing your guests’ crotches is to teach them a more polite greeting.
Dr. Sperry suggests reinforcing the “sit” command when guests walk through the door. This simple trick will keep your dog engaged and prevent awkward moments. You can even teach him a more fun greeting, like a high-five. Here’s how:
Make sure your dog is comfortable with the high-five trick beforehand. Have a friend enter the room quietly, and give your dog the cue to high-five. Reward him with a treat when he does it correctly, as rewarding polite greetings makes your dog more likely to choose them instead of sniffing.
Remember that when a dog sniffs your crotch, they’re not being rude; they’re just trying to get to know you better. If your dog often sniffs between your legs or other people’s legs, you can see this as a sign that they’re happy and using their natural senses in a completely normal way. It’s just your dog’s way of exploring the world and gathering information about those they encounter.
But if this behavior makes you or your guests uncomfortable, there are ways to redirect that curiosity, as we’ve outlined, through positive reinforcement. By encouraging alternative, polite behaviors, you’ll create a stronger bond with your puppy and ensure everyone feels comfortable.
