Some people often say

Dogs have a magical sixth sense

Can see things that humans cannot see

"Unclean" things< /p>

Anyone who has had a dog at home

should have had similar experiences

The dog will suddenly bark at an open place

So

Did it really see something

Is it something strange

1. The dog’s hearing is sharp beyond imagination

The dog’s hearing is very powerful

Far beyond humans

Human hearing range

About 16 Hz to 20,000 Hz

And dog hearing range

Then between 15 Hz and 50,000 Hz

That is to say

No matter high frequency or low frequency

Dogs can hear more than humans

p>

In addition

The structure of dogs' ears

also helps them capture sounds

Dogs have movable auricles

The auricles can be adjusted according to the direction of the sound source

to collect sound more effectively

This allows the dog to locate the direction of the sound source

and hear farther away

Both have advantages in sound

2. The dog’s sense of smell is unheard of and magical

There are about 2 100 million olfactory receptor cells

Humans only have about 50 million

This allows dogs to smell lower concentrations of odors

In addition

Dogs’ olfactory areas

also take up a larger proportion of the brain

This helps them process olfactory information more efficiently

Dogs’ powerful sense of smell

allows them to smell smells that we cannot smell

such as viruses, bacteria, diseases, drugs, etc.

Some working dogs

For example, German Shepherds and Belgian Malinois

Have better smelling abilities
