What's with the dog sticking out its tongue?

It's too hot! As we all know, the sweat glands on dogs are basically degraded, so they can't sweat, relieve summer heat and reduce low temperature. The only self-contained "air conditioner" is the dog's tongue, which radiates heat and regulates body temperature balance by sticking out its tongue frequently.

In summer, dogs frequently stick out their tongues to tell their owners that they are too hot and need their owners' help to cool down and relieve the heat.

Dogs often stick out their tongues when they are moved by thirst and send messages to their owners. The baby was thirsty and white smoke came out of his throat. Give me clean water as soon as you shovel shit.

If the dog is seriously short of water, it is also fainted by heatstroke, so the owner should pay more attention to ensuring that the dog has enough water.
