A dog will sniff your crotch simply because they are curious about you and want to learn more about your age, sex, and mood. There are training techniques you can use to discourage your dog from doing this but it is a natural thing for them to do.
They know if we are experiencing changes in hormones, such as those that occur during pregnancy. They may even know if we are experiencing illness or simply are in a bad mood. Some dogs are politer than others in their sniffing techniques.
So, if you've been away from your dog for a few hours or longer, your dog will sniff you butt to figure out where you went, if everything is okay, and—believe it or not—as a way to calm down and reduce stress from having been separated from you!

So, dogs know a person's individual smell and when illness changes that smell, dogs can notice that, too. Even humans can observe the scent of sickness with some health problems.

Dogs can be trained to smell several types of cancers, including melanoma, breast and gastrointestinal cancers and some infectious diseases in humans, including malaria and Parkinson's disease.
But can dogs really know and sense when we are sick? The answer is yes! Dogs, in particular, have several special ways that help them indicate if a person is ill or not. One of those ways is with their amazing olfactory abilities, or rather, their miraculous sense of smell.
There are dogs who have sniffed out medical issues that even doctors weren't aware of. Dogs can pick up on tiny changes in the human body, from a small shift in our hormones to the release of volatile organic compounds, or VOCs, released by cancer cells.
Ruefenacht said, “The big myth is that dogs are smelling blood sugar. But the dogs are actually sensing the compounds that come out of the liver when the blood sugar is either dropping rapidly or is low.” Though humans can't detect these smells, dogs likely can.
Dogs Are Reading Us
They sense our moods, follow our pointing gestures, and read us for information about what's going to happen next. That means they stare at us a lot to gain knowledge about their environment. Essentially, they are waiting for us to do something that will impact them.
Dogs can't get sexually attracted to humans because the two are biologically incompatible. Sexual attraction is different for dogs and they aren't lured by beauty, behavior, or other social cues. Instead, dogs are only aroused by Methyl p-hydroxybenzoate, a pheromone released by female dogs in heat.
Compared to people, who have about 5 million, dogs are super-smellers. And that's why they sniff outstretched hands, other dogs, and everything around them. Dogs can tell a lot of things from the scent of your hand; to a dog, your scent is completely unique and tells them a lot of things about you.
How far a dog smells depends on conditions such as wind and type of scent, but they have been reported to smell objects and people over 12 miles away. Dogs' olfactory systems work so well that they can be trained to pick up odors as little as a pictogram which is a trillionth of a gram.
The methodology of observing the dogs freely exploring the experimental area allowed us to determine the smells that were the most attractive to them (food, beaver clothing). Our study shows that dogs interacted more frequently with the scents of blueberries, blackberries, mint, rose, lavender, and linalol.

Four dogs participating in the study found the breath and sweat sample taken from a stressed person in 93.8% of the trials. Sign up for CNN's Wonder Theory science newsletter.
According to recent research, some dogs can actually detect breast cancer from the smell, which means that they could play a huge part in the early diagnosis of this condition in the future.
Not only this, but a person's brain chemistry changes when they're angry and dogs can smell that too, which signals them to see the person as a threat. The only exception appears to be psychopaths… because they don't experience many emotions, changes in their brain chemistry are rare and not sensed by doggos…
