First of all, the dog should be brought to a cool place, and the dog should not be exposed to the sun. Then, prepare enough water for the dog to avoid dehydration. You can also turn on the air conditioner or electric fan for the dog. However, the temperature of the air conditioner cannot be too low, otherwise the dog will easily catch a cold; if the dog is too hot, you can also give it a bath, but the hair must be dried in time after the bath. If it is a long-haired dog, the hair can be cut shorter appropriately.
