They don't sweat so they have to cool themselves some how.

"To stay cool, warm-blooded animals sweat or pant to loose heat by water evaporation. They can also cool off by moving into a shaded area or by getting wet. Only mammals can sweat. Primates, such as humans, apes and monkey, have sweat glands all over their bodies. Dogs and cats have sweat glands only on their feet. Whales are mammals who have no sweat glands, but then since they live in the water, they don't really need them. Large mammals can have difficulty cooling down if they get overheated. This is why elephants, for example, have large, thin ears which loose heat quickly. Mammals have hair, fur or blubber, and birds have feathers to help keep them warm. Many mammals have thick coats of fur which keep them warm in winter. They shed much of this fur in the summer to help them cool off and maintain their body temperature. Warm-blooded animals can also shiver to generate more heat when they get too cold. Some warm-blooded animals, especially birds, migrate from colder to warmer regions in the winter."

We sweat, and hot air comes out our sweat glands when we're active. (The hot air actually becomes sweat when it's happening a lot in a short period of time, and the vapor condenses on our skin).
Dogs don't have sweat glands. Their bodies do the same things ours does when they exercise, but the hot air is set up to escape through their mouth. They have a big mouth and big tongue which help dissipate the heat pretty well.

Heat exchange with the outside atmosphere. They do not perspire, so they have to slough off that heat from activity by panting.

there nose is wet and when they pant they inhale in their nose (if you look closely) and exhale out their mouths and because their noses are wet the air becomes cold when they inhale there for they cool down.

Because they do not have sweat glands like humans do!
