Dogs have a way of greeting one another that might leave you a little uncomfortable — sniffing each other’s rear ends. But when your furry friend turns their attention to your crotch, it can feel downright awkward.
So, why do they do this?
For anyone who’s ever had a dog, it’s no surprise that dogs communicate and greet others in various ways, with their sense of smell playing a key role. Dogs explore the world through their noses, and their sniffing habits are how they gather important information.
The dog’s superior sense of smell comes from 220 million scent receptors in their nose. That’s about 50 times more than humans have, giving dogs the ability to detect scents that are completely undetectable to us.
Simply put, dogs are incredibly curious creatures, and they have a keen sense of smell that helps them gather information about you.

Dogs are drawn to strong odors, explains Jennifer Sperry, a veterinarian with Pets Plus Us Insurance, tells Rover.com. Crotches, with their sweat glands and unique scent, are like a welcome mat for a dog’s nose. For medium to large dogs, the crotch is also easy to reach — much to the discomfort of your visitors.
Fortunately, there are ways to guide your dog’s curiosity into a more courteous greeting. Keep reading to find out why dogs sniff crotches and how you can redirect this behavior.
Why does my dog sniff crotches?
Ever wondered why your dog can’t resist sniffing your crotch? According to Rover, there are a few key reasons behind this behavior that might just surprise you.
First off, the height is ideal for a good sniff! But it’s not just about convenience —your crotch also has a unique feature that makes it a doggy hotspot.
The area is home to apocrine sweat glands, which produce a stronger, more pungent scent than those in other parts of your body. While these glands are also found in places like your armpits and chest, your dog’s nose likely won’t reach those spots.
Moreover, Dr. Sperry points out that dogs tend to target the crotch because it’s a more noticeable scent source compared to other areas, like your hands or feet. So next time your pup gets a little too friendly, remember — it’s all about their keen sense of smell.
Stop dog from sniffing crotches
So, 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 awkward spot. So, 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 might be tempting to scold your dog when they get a little 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 to more appropriate outlets. Here are a few fun alternatives to keep your dog’s nose busy:
- Snuffle Mats
- Puzzle Toys
- Nosework
- Sniffer Walks
By giving your dog an outlet to indulge their sniffing instincts, they’re less likely to focus on your guests’ private areas.
2. Teach a new trick
A great way to prevent your dog from sniffing your guests’ crotches is by teaching them a more polite greeting.
Dr. Sperry suggests reinforcing the “sit” command as guests walk through the door. This simple trick will keep your dog occupied and prevent awkward moments. You can even teach them 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 quietly enter the door.
- Give your dog the cue to perform a high-five.
- Reward your dog with a treat when they do it correctly.
By rewarding polite greetings, your dog is more likely to choose these over sniffing.

Remember, when your dog sniffs your crotch, they’re not being rude — they’re just trying to learn more about you.
If your dog often sniffs between your legs or others’, you can actually see it as a sign that your dog is happy and using its natural senses in a completely normal way! It’s just your dog’s way of exploring the world and gathering information about those they meet.
But if this behavior is making you or your guests uncomfortable, there are ways to redirect that curiosity. The key? Positive reinforcement! By encouraging alternative, polite behaviors, you’ll build a stronger bond with your pup while making sure everyone feels comfortable.
