Can you please explain how panting helps regulate a dog's body temperature?

Dogs don't sweat and even if they did, they are covered with fur so the fur would insulate them and keep the heat in. So they pant to get rid of excess heat from their bodies. The heat turns the water in their mouths into water vapor. In other words, the heat is used for a different purpose; instead of heating the dog's body, it is used to evaporate the water from the dog's mouth.

Van Hoeck

Evaporation of water from the tongue and interior of the mouth...evaporation is a cooling process...Dogs also sweat from the foot pads...(8
