Dog’s Sense Of Smell

What makes this small piece of machinery work?

Putting it in simple words, dogs can detect some smells in parts per trillion. It means a dog could detect a small teaspoon of salt dissolved in a big tank filled with water.
When a dog inhales air, the air travels into two different paths. One enters the pharynx all the way to the lungs and the other flowing directly into the olfactory section.

An Amazing Nose for Odors

What we don’t have that dogs have? They have something close to 300 million scent receptors, compared to just six million in humans.

A Presence of Second Olfactory System

Dogs have a second olfactory network. It is called “Jacobson’s organs or the vomeronasal organ”. This organ picks up pheromones, an important set of chemicals that display mating readiness.

It’s as if this organ functions with its own separate library of scents.

Do you know? Your dog’s nose is almost tens of hundreds of times as effective to smells as yours.
Do you Know? In reality, humans cannot wiggle their nostrils separately. Only dogs can.
