Did You Know That the dog's sense of smell is somewhere between 10,000 to 100,000 times more acute than humans?

The domestic dog is a domesticated descendant of the wolf. The dog is derived from an ancient, extinct wolf, and the modern grey wolf is the dog's nearest living relative. The dog was the first species to be domesticated, by hunter-gatherers over 15,000 years ago, before the development of agriculture.

They possess up to 300 million olfactory receptors in their noses, compared to about six million in us. And the part of a dog's brain that is devoted to analyzing smells is about 40 times greater than ours. Dogs also have something called neophilia, which means they are attracted to new and interesting odors.


According to the researchers, the dog's sense of smell is somewhere between 10,000 to 100,000 times more acute than ours. So, no surprise, the dogs are used for following the footprints or in detecting the explosives.
