It is normal for dogs to pant when they are hot. Because dogs do not have sweat glands, they need their tongues to dissipate heat. At this time, you need to prepare enough water for the dog to avoid dehydration or heat stroke, and then keep the dog in the shade. In a ventilated area, you can also turn on the air conditioner or electric fan for the dog to help the dog cool down quickly. It is best not to let your dog go out when the weather is hot to avoid heat stroke.
