The Nose Knows! Just How Powerful Is A Dog's Nose
While we have 5 million scent-detecting cells, the bloodhound boasts 300 million, and even the dachshund puts us to sniffing shame with his 125 million scent receptors.
The Powerful Nose and Brain
Your canine can identify smells somewhere between 1,000 and 10,000 times better than you can. A dog’s olfactory skills are not just limited to his snout power. A dog’s brain is specialized for analyzing and identifying scents; the percentage of a dog’s brain devoted to smell is 40 times larger than that of his human.
Interesting Dog Nose Facts
Even the moisture on your dog’s nose plays a role in his keen sense of smell. The mucus on your dog’s nose provides a surface for dissolving chemicals in the air. Have you ever noticed that Fido’s nose is wetter when he is actively sniffing and investigating his surroundings versus taking a nap? A dog will often lick his nose in order to introduce the chemicals to another olfactory sense organ on the roof of his mouth.
Have you ever wondered what your mutt is analyzing as he sniffs out where another dog marked? From a single drop of urine, your dog determines the other animal’s sex, health, diet, and mental state. From his sniff, he knows whether the animal is dominant or submissive, and friendly or aggressive.
Talk about leaving your mark!
As though his sniffing capabilities were not cool enough, a dog’s nose has another purpose. The tiny holes in a dog’s nose also help him to release heat, making it useful for cooling off.
