Dogs panting and shivering sharply with their tongues out Dogs panting and shivering sharply with their tongues out are trying to dissipate heat, either because they have just done intense exercise or because their body temperature is too high in the heat. The sweat glands on the dog’s body surface are not well developed, and sweat can only be excreted through the pads of the feet and tongue. When a dog’s body temperature is too high, the chest is often the hot spot, and panting with the tongue out can quickly exhale the hot air from the chest to achieve the cooling effect.
