Why does the dog always stick out its tongue in summer?

Why does the dog tongue in summer? Why does the dog tongue in summer?

In fact, it’s the heat the dog is giving off. Not only dogs, but also people and other animals. When it’s very hot, they sweat. Sweat comes out of many small holes in our skin. These pores are called sweat glands.

The sweat glands of dogs are special. The skin of the dog is not connected to the flesh of the body. Connected by a membrane. Pores can’t dissipate heat. They can only dissipate heat by tongue and running head.

In other words, the dog’s sweat glands are on its tongue. When it’s hot, the dog will stretch out its tongue, speed up its breathing, let the sweat flow out faster, emit heat, and feel cool.
