Dog’s nose – Understanding their Incredible Sense Of Smelling

The dog’s incredible sense of smelling thing is considered unmatched. The unbeatable sense of dog’s nose is enough to blow anyone’s mind. They are remarkable when it comes to remembering scents. Even if we are supposed to compare human and the dog sense of smelling , there are many figures that come into the expression which says dog’s nose is 10, 100, 1000 to 1,00,000 times better than that of the human nose. Various studies give various results.


Dog's nose
This can be the prime reason dogs are trained in detecting bombs, weapons, explosives or drugs, tracking or attacking enemies etc. Here I will specifically mention that dogs are considered as the most effective bomb detectors. No machine or equipment can beat the dog’s nose. This statement makes more valid when I say even after spending billion dollar amount.

A. What makes a dog’s nose so distinguished than others? 
Even if the smell is covered or masked by other odors, a dog can smell it and that too individually. The interesting part of the dog’s nose. There is a possibility as they smell in layers.

We can take the reference of one of the recent surveys, which proved that a dog’s nose can even smell cancer. As we all know cancer is a deadly disease that is taking lives of many. If the same happens, this can definitely cure and save millions of cancer patients.

B.This leads us toward a question. Why so? How can a small four-legged animal smell better than human? How is it possible?

This can be explained as-

• The olfactory membrane – It is a thick yellow structure, that consists of about one hundred million smell receptor cells. Which is responsible for the sense of smell.

• The human nose has only three square centimeters of the olfactory membrane. Where if we take only for an example  one breed like bloodhound which has about 150 centimeters of the same.
Jacobson’s Organ – A particular organ which we human does not possess. This organ is located at the bottom of the dog’s nasal passage.This organ helps the dog’s nose to pick important cues which in turn are the signal messages for other dogs like mating, readiness etc.

These organs give the  dog’s nose a remarkable capability to smell bombs and explosives as well.

 C. How does a dog breath vs How does a human breath?
Whenever a dog breath, they take a deep breath. They use a short sniffing action while smelling. Whereas we humans breath in and breath out from the same airway passages led through our lungs. Also while smelling some particular scents we humans need to take several sniffs.We, humans, perceive the world through our eyes means vision likewise dogs perceive the world through their nose means to smell.

 D. How far a dog’s nose can smell?

Above mentioned is one of the common questions you might wonder? To explain it in simple terms it would be better if I give some of the examples like –

• The surprising fact is that a dog’s nose can literally sense a tiny amount of smell diluted in air,

• A dog’s nose can smell things buried 40feets beneath the ground.

• Experiments say, a dog’s nose can smell 1 or 2 parts of smell even diluted in per trillion too.

After doing the detailed analysis of who has the best sense of smelling. We have an answer it’s the dog or I should say The dog’s nose. The capability of dog’s nose in catching the smell at long distances crowns them as renowned rescuers.

It is difficult to mention in numerals as how many people have been rescued till date? Even if we start calculating. Hereby, we can proudly say dogs are the best to perform the task of saving the rescuers. And all credit goes to the dog’s nose.

The remarkable skill of the four-legged animal makes him the proud winner of who has the best sense of smell. Leaving behind humans as well.  The dog’s nose can not only smell bombs, humans, whale poops, DVD or any living thing buried beneath the land or water etc. But our emotions too.

The dogs were the best and will continue being the best. They are the sacred rescuers with just sniffing things. It would be difficult to provide the best security, without dogs. They not only protect us from upcoming dangers and also saves us when we are in danger. Making them extremely valuable. Which gives us a sense of responsibility to care for them. The ultimate conclusion says that the dog’s nose is best in smelling. Also considering them as the best in service and even proved many a time.
