Dogs can blow an electric fan, but they cannot sleep with the fan blowing on at night, because the cool breeze blowing all night will cause the dog to catch a cold. When the temperature rises, the dog can be placed in a ventilated and cool place. In the room, you can also turn on the electric fan or air conditioner appropriately to help the dog's body cool down, but the dog cannot be left in the cool breeze for a long time.
