Unlike humans dogs do not cool off by sweating through their skin. The only way they can lower their body temperature is to pant, and sweat a little bit through their paws. To pant effectively, they rely on the air around them being cooler than their own temperature; this allows the heat in their moist breath to dissipate and be removed into the environment. They also rely on the environment being a little dry. The air they exhale is 41oC which is why they rapidly over heat in cars.
