DOG SMELLING
I’m sure you’ve heard it a thousand times: a dog’s vision is much more limited than that of a human, because he can’t distinguish colors. In fact, they often say that they see with their sense of smell, which compared to it is hyperdeveloped. And it is that the nose of a cane actually works through an infinitely more complex mechanism than ours.
As soon as there's a gust of wind, its fluffy truffle helps to catch every aroma the breeze brings, and then record them "in stereo". That is: each nostril collects the odors separately, allowing you to distinguish not only from which source they come from, but where each of them is located.
To be more precise, as soon as the air enters the dog's nose, it meets two compartments: one for breathing, and the other for smelling. So it goes through its receptive cells for smell, which are incredibly numerous compared to humans. Up to 300 million put themselves in their noses compared to the 5 million we have.
Let’s say that his sense of smell is much more advanced than ours, and there’s actually more evidence to reclaim the goodness of an organ that functions like a Swiss clock. While the man inhales and expires using the same hole, his four-legged friend collects air through the front tombs, but expels it through the sides of such slits, generating air movements that facilitate the introduction of new molecules of smell. Molecules whose information is processed by a much more developed brain than human, having a larger „smell bulb”. They distinguish and remember a wide variety of smells.
Come on, if we are able to smell and recognize who brings it to the front in a small room, the dog would be able to assimilate every of the ingredients in it... standing in the middle of a football field . Everything has a distinctive odor profile for dogs: every animal, or even insect found on a tree on the street. And he can know where he is and in which direction he’s going.
The dog’s nose can detect things that aren’t even visible: thanks to its vomeronasal organ, located on the upper palate of its mouth, it detects hormones that all animals (humans included) naturally release. This alerts them of threats, tells them if they or they are potential friends or enemies, warns their moods and even allows them to identify illnesses and to deduct if the woman in front of them is pregnant. Have you ever wondered why they help you when you're sad or they get mad when they see you angry? Why such moods depress hormones.
There is the other one. As if the advantage they bring to us in the matter wasn’t enough, their smell travels through time! The past manifests itself by leaving fragrant traces after someone passes or imbibing in his body aromas of sites that have been there. And the future is in the breeze that carries with it the smells of those who are approaching. So trees, corners, and road signs become real daily for the dog. They tell him who passed by and what he ate...
