Although it may seem strange, the truth is that when two dogs cross the street, the usual thing is that they stop and smell their tails. To be more exact the dogs smell the anus, which is the area where the anal glands are located, which give off the smell that characterizes and identifies them.
Dogs recognize each other thanks to their smell, in the same way that when they do not know each other, they appear sniffing their butts. As unpleasant as it may seem on a personal level and from a human point of view, for dogs it is the most natural thing in the world. So we should always let our dog smell the ass of other dogs and other dogs can smell theirs.
Dogs have a very personal smell in their anus, due to a liquid released by their anal glands. This smell is unique, in the same way that fingerprints are in humans. So that each dog has a completely different smell to the smell of other dogs, a totally personal smell.
The dogs can know thanks to that smell many things of the dog to which they are smelling the ass. They can know their approximate age, the type of nutritional diet they have, the mood and even the state of health of the other dog, among many other examples.
Letting it smell and that you smell your ass is a fundamental part to socialize a dog correctly, is a fundamental and essential way of communication between dogs (remember that they have the smell thousands and thousands of times more developed than humans ).
We must never avoid that our dog smells the tail of another dog, nor that another dog smells our ass to ours. It is a totally natural and necessary act among dogs.
Why do dogs smell their parts?
In addition to smelling the anus, something that is completely normal and normal. Dogs also tend to smell their intimate parts, their genitals. The genitals of a dog also provide an odor, so that other dogs can get even more information by simply sniffing a bit.
The urine of a dog leaves a very characteristic smell that other dogs identify easily, it is not as personal a smell as that of the anal glands, but it is also quite personal.
In this way if our dog smells the genitals of other dogs, you can know if you have urinated somewhere where he has walked, if it is a female or a male, if it is in heat in case of being female, if it is sick, etc. …
It is something completely normal and natural, even sometimes suck a little, to increase even more the smell and in a certain way, savor it. Dogs communicate like this and we should not bother them when they do, it’s their way of communicating.
