HOW GOOD IS A DOG'S SENSE OF SMELL

Hello, I'm Hamilpet! 🐶🐶
 
Even though it is autumn🍁, the weather is still hot!
It's easy to catch a cold if it suddenly gets cold, so take care of your health!
 
Today we are going to talk about a dog's sense of smell and nose! 🐶
 
It's a well-known fact that dogs have a great sense of smell!
A dog's sense of smell is the ability to track prey, and in a herd, the individual with this ability is the leader.
This survival instinct may have led to the development of the sense of smell.
 
This sense of smell is determined by the width of the olfactory epithelium in the nose and the number of olfactory cells.

Dogs have longer noses than humans, their nasal passages are wider than humans, and a much larger number of posterior cells are distributed in the large nasal passages~ 😤

In the case of the olfactory epithelium, there are more wrinkles and the surface area is 10 to 50 times larger than that of humans.
Compared to humans, which have about 5 million olfactory cells,
Dogs have about 200 million, so can you guess the sense of smell?
 
This is not the end, and the odor detection sensitivity of each cell is also much more sensitive than that of humans.
It is said that the ability to distinguish the components of sweat is 1 to 100 million times that of a human.
 
Perhaps because of the development of the sense of smell, dogs use more than 40% of the sense of smell out of the five senses.
On the other hand, humans use sight 80% of the five senses.

Because of this great sense of smell, the dog's emotions as well as sexual arousal are triggered by the stimulation of smell. 😍

If the average human can smell a few meters,
It is said that dogs react to the smell of a female 10km away in heat. Can you really feel the difference?
 
I think it's hard to imagine a dog's sense of smell in numbers.. 😅 😅
 
And one more!
The fact that a dog's nose is always moist is also closely related to this ability to smell!
 
There are two main reasons.
 
1. The first is to maintain the sensitivity of the sense of smell.
 
In order to understand this, we need to understand particulates. In the air, particulates, the smallest unit of odor, float.
When you breathe, it goes into your nostrils and you can smell it!
In order to distinguish odors in the air, it is necessary to hold odor particles in the mucous membrane of the nostrils.
At this time, if the mucous membrane is moist, it is easy to trap the particles!
So the dog always keeps it moderately wet by licking its nose.
This allows you to know the direction the smell is coming from.
 
2. The second is due to the mucus in the lacrimal glands.
 
Dogs, like humans, have a nose connected to the lacrimal gland.
Because tears are always stored, this mucus keeps the nose moist except when sleeping.
 
So you can check your dog's health through his nose.
A dry nose may be a sign that the body is out of balance and there is something wrong with your health.
You also need to pay attention to dog’s health when you feel heat on the surface of his nose, peel off the surface of your nose, or run a runny nose.
