Why do dogs stick out their tongues when the weather is hot?

It is heat dissipation, because dogs have no sweat glands and can only stick out their tongues to dissipate heat. As long as the temperature rises, their tongues will dissipate heat. Sometimes dogs stick out their tongues to express their happiness when they are excited. My dog always likes to laugh like this. After two laps, he would stick out his tongue and laugh for a long time. Pretend cute and sell cute, maybe everyone will praise him cute and reward him with something. Slowly, the dog will know that he will be praised and liked, so he will stick out his tongue and seek praise and attention. Dogs are very heat-resistant animals because they don't sweat or stop working because of the high temperature.

The dog's body can't adjust its own temperature, and the dog can't take care of itself and keep moisture; The sweat glands of the dog are all on the tongue, so seeing the dog sticking out his tongue and panting means that the dog is very hot and needs to drink water to cool down or calm down. Dogs with short noses are more prone to fever and less prone to heat dissipation than dogs with long noses. As long as the body temperature is too high, it will use sweat to cool down and expel some water from the body. Because there is no sweat on the dog and its body temperature is not higher than that in the cave, it will cool down and expel water from the body. Only by opening your mouth and sticking out your tongue to breathe will some water flow out along your tongue.

In hot summer, dogs can't excrete heat through sweat glands. They can only expel excess heat by sticking out their tongues. Dogs use their long tongues to evaporate saliva, take away heat, dissipate body heat and restore normal body temperature. Dog hair does not interfere with heat dissipation. Don't shave the dog's hair too clean in summer. The coat has a certain thermal insulation effect. If it is very hot in summer, you can cut it to 2-3 cm. This will make the dog feel cool without exposing its skin to the sun.
