When you see that the dog is not sweating, can the electric fan be cooler? You should know that the way to dissipate heat from an animal body is not just sweating. The main heat dissipation areas of animals are the skin (75-85%), and other heat dissipation channels include respiratory organs (smog), digestive organs (pooping poop), and urination.
The main ways to dissipate heat in constant temperature animals:
1. Radiation heat dissipation

The body heat dissipates heat to the outside world in the form of heat rays (infrared rays), and accounts for 70% of the total heat dissipation under normal temperature and quiet state. That is to say, at room temperature (about 25 degrees Celsius), when the dog is calm, it mainly relies on the skin to radiate the body's heat, and does not need to sweat to dissipate heat.
2. The heat from the conductive heat dissipation
body is directly transferred to the colder object in contact with it. That is, dogs can dissipate heat by licking ice cubes, lying on the cool ground, etc.
3. Convective heat dissipation
The way in which the body is in contact with the body surface flows to exchange and dissipate heat. The hair dryer belongs to this kind of heat dissipation. The blower fan increases the rate of heat removal by enhancing the flow of gas similar to the skin, achieving the purpose of making dogs cooler.
4. Evaporation and heat dissipation
The body generates heat from the heat of the body through the evaporation of moisture on the surface. In addition to the increased discharge of sweat, the original moisture evaporated on the surface of the skin can also take away heat. For example, sprinkling water on a dog will not only transmit and dissipate heat, but also evaporate heat dissipation if the water evaporates.
To sum up, sweating is just one of the special ways for dogs to dissipate heat after exercise. In addition, the above four heat dissipation methods can also cool down the dogs, so the hair dryer can of course make dogs whose body skin does not sweat more cool.
