Why Do Dogs Sniff Their Own Bum

  • Dogs’ scent-driven curiosity is about learning new things and introducing themselves.
  • Certain human crotches pique canines’ interest more than others.
  • people who have lately given birth, menstruated, or engaged in sexual activity

The world of human limits is not well understood by dogs, particularly when it comes to using their scent. They frequently welcome new humans the same way they frequently meet new dogs: with a brief sniff of the behind. Dogs will readily press their noses into the crotch of any human, whether they are the owner or a guest. Even while intrusive sniffing might be humiliating, especially if your dog does it to a guest, it’s only a way for them to say hello and get to know them.

The canine nose is a potent instrument. Humans only have 6 million scent sensors in their nostrils, however dogs can have up to 300 million. This indicates that they have a 10,000-fold better sense of smell than we have. The Virginia Maryland College of Veterinary Medicine’s Michael T. Nappier, DVM, DABVP, used the example that dogs can “detect the equivalent of a 1/2 a teaspoon of sugar in an Olympic-sized swimming pool.

Dogs even have a special organ above the roof of the mouth called the vomeronasal organ, which plays a significant role in how a dog interprets smell and is connected to the scent-dedicated part of the dog’s brain, which is about 40 times larger than that of a human. This is why dogs are used to sniff out drugs, bombs, cancer, insulin levels, bed bugs, and more.

So Why Do Dogs Sniff Human Crotches?

But how does that relate to a dog’s need to prod a human in the crotch? It all comes down to sweat glands, specifically apocrine glands. These glands release pheromones that can communicate a variety of information, including a mammal’s age, sex, mood, and ability to reproduce. Dogs have apocrine glands all over their bodies, but the genitalia and anus have the largest concentration, which is why they like to sniff each other’s butts.

Since they want to know if a female is ovulating or pregnant, intact male canines are renowned for being exceptionally enthusiastic sniffers when looking for a mate. Humans, like the majority of mammals, have apocrine glands. These glands are primarily found in the armpits and genitalia of humans. A dog usually only has access to a human’s genitalia, therefore it goes there to collect information. Due to their keen sense of smell, scent dogs like Bloodhounds, Basset Hounds, and Beagles are more inclined to sniff at crotches.

What Can a Dog Sense From Smelling Your Crotch?

Certain human crotches are more likely to draw a dog’s nosy attention than others:

  • Those who have lately engaged in sexual activity
  • the menstrual population
  • those who just gave birth

A dog will be intrigued by all of these. This is due to the greater pheromone excretion of those individuals. Because of this, even though a dog is familiar with their owner, if that person has recently given birth or is menstruation, the smell they are giving out is different, and the dog is curious as to why. This may also be the reason why underwear is frequently stolen by dogs, as it contains the fragrance of the owner.

Because dogs can detect pheromones, they might be able to determine when a woman is ovulating. Stanley Coren, PhD, DSc, FRSC, describes how Australian Shepherds were taught to detect cows that had just ovulated in his book, How Dogs Think. Ranchers have used this technique to breed cows during their limited breeding window since it is allegedly simpler than other methods of predicting ovulation in livestock. Dogs can at least sense changes in their owners, even though it hasn’t been shown beyond a doubt that they can detect ovulation in humans. The capacity of a dog to recognize ovulation may also include the ability to identify ovarian cancer.

How Can You Get Your Dog to Stop Sniffing the Crotches of Your Guests?

While a dog’s scent-driven curiosity is all about learning new things and saying hello, you and your guest might want to stay out of the uncomfortable scenario.

If your dog enjoys sniffing people’s underwear, you might want to make sure that once a visitor enters the house, they give your dog their hand or fist to sniff first. This gives the dog something other than a crotch to concentrate on. The dog can still learn about the new person with a fist without having to get up close and personal. Additionally, you can teach your dog to sit when a visitor enters the house.

Therefore, consider the dog’s nose in your crotch to be a form of small conversation. Yes, it’s uncomfortable, and you want to get beyond it, but it’s an opportunity to learn a little bit about someone. No matter how embarrassing, a dog’s sniff can tell them everything.

For dogs who enjoy utilizing their noses, AKC Scent Work is a fantastic pastime.

Why does my dog constantly smell her own behind?

Smaller dogs, such as Cocker Spaniels, Chihuahuas, Beagles, Miniature Poodles, etc., do appear to have a higher propensity for anal sac disease and problems such a full or impacted anal gland, however it doesn’t appear to be a breed-specific concern.

Anal sacs that don’t naturally empty in dogs may result from their diet. Large, firm stool will typically naturally start the discharge during a bowel movement. If the anal sacs are not activated by a little or soft stool, they will continue to fill up. Even when the dog’s excrement is perfectly hard, the dog may nevertheless experience full or anal gland impaction. If you empty them for a dog that didn’t require it, you can also create problems. Leave well alone if your dog has no issues in this regard.

A dog with full or anal gland issues may slide their bottom around the floor, scratch, bite, or lick their tail, have a fishy odor at their back end, appear in pain or depressed, or react to anyone approaching their back end.

  • They stomp their bottoms on the ground (scoot)
  • Attempt to lick, scratch, or bite at their bottom (or even other areas of their body like their feet)
  • a fishy odor coming from the bottom (or breath, if they have been licking their behind)
  • Lessen the tail wag
  • seem downhearted
  • They object to having their tail raised or handled

Scooting and a fishy odor are clear signs of anal gland dysfunction. If the anal glands become overloaded and begin to leak outside of when the dog is going potty, the smell of fish develops. Anal gland fluid smells strongly of rotten fish. When the dog is picked up or at rest, full anal glands may leak.

It’s a popular myth that a dog with worms will drag their bottom on the floor. In truth, full anal sacs are more likely to blame. Your dog is attempting to expel the fluid and get comfortable. Anal glands that are full but releasing some fluid are the source of the overpowering fishy odor. It can be coming from your dog’s bottom or your soft furniture.

If you see these symptoms, your dog may have a problem with the anal sac or with the way the anal glands naturally empty. If it only occurs sporadically, that is perfectly normal and poses no threat. Help is only required if the issue persists frequently with your dog.

Always consult a veterinarian to ensure that the issue is anal sacs and there isn’t an infection before proceeding.

Your veterinarian or your neighborhood dog groomer can assist if it is a rare issue or you don’t feel like trying to empty them yourself. It only takes five minutes to complete the process. Alternatively, if you have some patience and knowledge, you can do anal sac expression yourself. However, it is advisable to visit your veterinarian the first time so they can examine your dog. Your veterinarian will typically agree that going forward you, the dog owner, can empty them at home once infections or other problems are checked out. An excellent veterinarian will be pleased to provide you with guidance on how to do this.

Yes, with a little work, tolerance, and kindness. The idea is to do things gently and to relax—both you and the dog, of course. Avoid rushing, panicking, or exerting excessive force. Be patient and kind.

My dog keeps staring at his behind. Why?

It’s possible that your dog is staring towards her rear because something there is hurting her. Dogs who are in agony may also pant. Lucy’s discomfort could be brought on by an anal gland impaction or rupture, severe constipation, or uncomfortable gas.

Can humans make dogs sexually aroused?

The simplest response to the question of whether humans can turn on dogs is no, our canine friends cannot be turned on by us.

In actuality, dogs do not experience sexual attraction in the same manner that people do, in addition to being genetically distinct from humans.

Reproductive Isolation.

Reproductive isolation is the easiest explanation for why our canine companions don’t develop a sexual interest in people.

This indicates that although though humans and dogs are both mammals and share some genetic traits, we are actually separate species.

Due to our genetic differences, we are just not naturally predisposed to have sex with one another.

But hold on, does it indicate that since chimpanzees and other creatures with whom we have ancestors share DNA with us, we humans can also reproduce with them?

Again, no is the response. This is due to the genetic separation between our two species caused by thousands of years of evolution, which has resulted in reproductive isolation naturally.

To ensure that each animal species on the globe continues to exist as its own species over time, reproductive isolation is required.

This explains why we humans are attracted to our own species and not to other mammals like chimpanzees or dogs because we are driven to reproduce biologically.

Genetic Differences.

It is obvious that the genomes of dogs and humans are not compatible. Despite sharing many of the same genes due to having similar ancient ancestors, we are too different from one another to have children.

The genetics of our closest companions affect their biological development in ways that humans’ genomes do not.

The function of genomes is to act as a form of blueprint for how a particular species should be constructed.

Of course, a dog’s genomes cause it to grow two sets of legs, a tail, paws, and a furry body.

Human genomes instruct the body to grow only one set of legs, two arms with opposable thumbs, a less amount of body hair, etc.

The quantity of chromosomes that humans and dogs have differs significantly genetically and prohibits both sexual desire and reproduction.

To produce new children, chromosomes need to bind to one another. Dogs and people cannot interbreed since they do not share the same chromosomes.

Dogs Experience Attraction Differently.

Dogs lack the capacity for higher reasoning and logical thought like humans have.

Humans have evolved the capacity for logic and reasoning through thousands of years, enhancing our chances of survival by ensuring that we are not only motivated by sexual drives.

Humans experience three types of love: attraction, attachment, and lust, whereas dogs only feel attraction and attachment, albeit in slightly different ways.


Competition is the first consideration. Male humans have a propensity to be drawn to women who have numerous suitors, and vice versa, as you have probably noticed.

Our desire to have children with a person of the other sex who has many suitors to select from is biologically embedded in our minds.

Personal preference is the additional consideration. It all comes down to sexual orientation, physical characteristics, behavioral qualities, and other subtle aspects of human nature that affect attraction.

Pheromones that indicate fertility are the only substances that draw male dogs to female dogs and vice versa.

Dogs’ anal glands secrete pheromones, distinctive scents that indicate various moods, including the need for sexual interaction, fear, aggression, etc.

Dogs don’t find humans sexually attractive because only other people are attracted to the many pheromones that humans emit.

Dogs are not prejudiced against other dogs based on their gender, personalities, appearances, or competitiveness.

When they detect a female dog’s pheromones, male dogs will seize any opportunity to mate.


Byproducts of spending time with another person, both physically and mentally, include bonding and connection.

The hormone oxytocin, which the pituitary gland releases when we engage in sex, affection, or romantic love, is responsible for this.

Oxytocin is released during mating, and this results in feelings of connection and bonding in our canine companions.

But unlike in humans, this attachment is not nearly as strong in dogs.

Regarding dogs developing attachments to people, we are all aware of their extraordinary loyalty and devotion to their owners.

Dogs are pack animals, and they typically regard their owners as the leaders of their pack.

Dogs are not only emotionally bonded to the pack leader, but also feel compelled to adore and guard them.


Lust is a subconscious psychological drive that is only present in humans and is known as desire.

Only humans experience this desire for sexual fulfillment without the urge to procreate.

However, unlike humans, dogs and other animals do not experience carnal lust.

However, this is due to the fact that in order to ensure that they carry on their genes, they are naturally programmed to mate numerous times over the period of several days when a female dog is in heat (or estrus cycle).

Fun fact: When mating reaches its peak, our canine companions have orgasms just like we do.
