Although for humans it is a somewhat uncomfortable and embarrassing behavior, capable of putting us in a hurry, for dogs it is something so normal and social that they will do it over and over again. Dogs smell people’s crotch or bottom to get information about them.

The most developed sense of a dog is its sense of smell, which is more than ten thousand times higher than that of humans. When two dogs greet each other they normally sniff each other’s butts and genitals, thus obtaining a wealth of important information.

The age of the other dog, its sex, if it is in heat or not, if it has recently given birth, if it is sick…. So much information can be obtained by simply smelling pheromones concentrated in the genitals that they try to do the same with humans.

Why do dogs smell the crotch? How to act

If a dog smells the crotch or even the butt of another person, we must understand two basic things: The first is that this person may find the behavior of the dog uncomfortable and the second is that it is a totally natural behavior in the dog, which we should not punish.

The dog will smell the person’s crotch because they may have had sexual intercourse recently, are menstruating, have given birth, are sick, or simply because they are curious and want information about that person.

However, for the person, the situation can be very uncomfortable, so we will simply remove our dog and ask him to sit down. But without scolding him, since he really isn’t doing anything wrong. We will apologize to the other person and continue on our way.

Humans concentrate a lot of pheromones in our private parts in the cases mentioned, so it is not surprising that the dog is attracted to these smells. Totally normal behavior within the animal kingdom.
