On a hot day, any dog owner may notice their pet's tongue sticking out.
Why does a dog “extract” a mobile muscular organ precisely in conditions of high air temperature?
There is a simple explanation. The fact is that our four-legged friends' tongue plays an important role in thermoregulation.
Why does a dog stick out its tongue in the heat?
Dogs have few sweat glands that secrete moisture.
This is why the process of thermoregulation occurs in these animals in a special way - by sticking out the tongue.
The pet only needs to “extract” this organ, and it will begin to cool quickly, as the saliva will evaporate.
As a result, the animal's body will get rid of excess heat.
Other reasons why a dog might stick out its tongue
As you know, dogs stick out their tongues not only in hot weather.
Animals behave similarly when running and playing actively.
The reason is practically the same: you need to get rid of excess thermal energy.
A dog may also encounter the need to stick out its tongue in a stressful situation. After all, the heart rate increases, as does the body temperature.
By the way, the same processes can occur at the moment when the dog is happy about something.
Earlier we explained why a dog barks “into the void” at night.
