3 Pieces of Dog Trivia! Dogs Are Just So Amazing (Case) 🐕

Hello everyone! This is 8ushio8.

Dogs aren't just "cute companions."
Actually, they possess some truly amazing trivia.
Whether you're a dog lover or not, please read until the end.
This time, I'll introduce three surprising pieces of trivia related to a dog's "nose"!

Astonishing sense of smell! Just how far away can they detect scents!?

Did you know that a dog's sense of smell is about 1,000 to 10,000 times more sensitive than a human's?
For example, a scent that we think is "faintly fragrant" is like "extremely strong perfume" to a dog.

Moreover, depending on the wind direction, humidity, and breed, they can track scents from hundreds of meters away.
Hunting dogs and search dogs can reportedly track scents from over 1-2 km away. They are just too professional.

What's even more shocking is that dogs can detect scents at the ppb (parts per billion) level.
At this level, it's basically a "superpower," isn't it?
It's no wonder that "medical dogs" exist who can detect explosives or signs of diseases like cancer.

So, I got a little curious and looked up the human sense of smell, but...
The only thing we can boast about is the "variety of scents we can distinguish."
It's said that dogs can distinguish billions of types, but some research suggests humans can distinguish 1 trillion types of scents.

If dogs excel in "quality," maybe humans have been competing in "quantity"?
......No, even so, dogs are still just too amazing.

Is a dog's nose the same as a "fingerprint"!? The secret of "nose prints"

Now, dogs are the owners of such amazing noses.
Did you know that the nose itself can serve as an "individual identification ID"?

Dogs have patterns of wrinkles and grooves on their noses called "nose prints," and these are actually different for every single dog.
It's surprising because, just like human fingerprints, no two dogs in the world have the same nose print!

In fact, in Canada, research on individual identification of dogs using nose prints has been conducted since the 1970s, and recently, services have appeared that allow you to photograph and register nose prints using smartphone apps.
Since it can be used for preventing lost pets, anti-theft measures, and individual identification at hospitals, it's basically like "the nose is a social security number."

By the way, cats also have nose patterns, but it's unique to dogs that they are so well-suited for individual identification.
The evolution of their "nose" is truly amazing.

Dogs read emotions through "tone of voice" rather than "words"!

You've probably thought, "My dog seems to understand words!" right?
But actually, for dogs, "how you say it" is often more important than the words themselves.

For example, if you say "Come here" in a gentle voice, they will happily come over, but if you say the same "Come here" in an angry voice, they won't come at all.
......You've experienced this, right? (I have)

This is because dogs are reacting to the human "tone of voice" and "emotions."
The latest brain science research has revealed that a dog's brain processes "word meaning" and "tone of voice" separately.
Especially when a gentle voice is paired with praise, the "reward system" area of the brain that makes them feel "Yay!" reacts.

In other words, "how you say it" is more important than "what you say."
Dogs are really reading the "total atmosphere," including gestures and facial expressions.

Summary: A dog's nose is definitely cheat-level.

• A sense of smell that can detect scents kilometers away • An identification ability where the nose itself acts as a "fingerprint" • A sensibility that listens to the "warmth of the voice" rather than words
Like this, a dog's "nose" is packed with more capabilities than we think.
I feel like I'm going to stare at a dog's nose again...!
