Dogs are afraid of heat. When the temperature rises in summer, dogs will stick out their tongues to help dissipate heat from their bodies. Owners can prepare ice pads and clean water sources to cool down their dogs, or take their dogs to a ventilated and cool place to stay. Wear it to prevent your dog from getting heat stroke. You can also use a fan or air conditioner on your dog appropriately, but be careful not to do it for too long, otherwise it will cause your dog to catch a cold.
