Canines have so developed this ability that allows them to feel unimaginable odors for humans.
The dogs They were the first animal domesticated by the human race 30,000 years ago and have an anatomical structure in their nasal cavity capable of perceiving smells that no human gets to capture. This ability makes the canines form a park of rescue groups and security agencies of each country, such as a complement of great value to help disrupt drug bands.

How does smell work in dogs?
In technical terms, studies and research discovered that humans have six million olfactory receptors, while dogs reach an approximate amount of 300 million. Another fact is that people inhale once per second; unlike the canines, who do so five to ten times.
The specialists indicated that our dog’s nose detects a phenomenon called “Weak thermal radiation”, Which perceives the body heat emanating from human beings. This makes them able to orient, and even hunt a dam, even with problems of view, smell and ear.

Another important point to highlight about its physiognomy is that each nasal pit is independent From the other: when exhaling the air, it comes out quickly for new odors to enter. In this way, the respiratory system has this great peculiarity that can be very useful, although, on the other hand, they transform the dog into a sensitive pet that can get sick or stress with the sense of smell. It is for this reason, that they are capable of finding lost children or injured people in a catastrophe, which are trapped under the rubble and cannot go out by their own means.
And the data that surprises everyone: Dogs can visually represent a smell. By maintaining a connection between the respiratory system and the brain, the dogs, according to an article by National Geographic, have the ability to “mentally represent what they want to look for”, from this developed sense. That is, through smell they create their own world.
