Humans use water to dispose of exess heat by sweating.
they try to waggle their tail and wallow themselves in pool of water thus releasing excess heat
Humans sweat in a tropical heat.
Most terrestrial animals dissipate excess heat by evaporation. This is done by either sweating (like humans) or by panting (like dogs).
Panting is a dog's way of getting rid of excess heat. Dog's can't sweat, so they deal with excess heat by evaporating water through their mouths. They get hot for the same reasons as humans - high ambient temperature, physical exertion, and stress. If it's persistent and/or more of a deep, labored sort of breathing, it might indicate a medical problem, such as heart failure. (Again, same as humans).
Sweat glands
The gullet helps maintain homeostasis by removing excess water.
Evaporation cooling
It helps the body remove heat through sweating, and it also allows it to use water as an energy source.

The engine of a car contains many passages through which water can flow. The water picks up excess heat from the car engine and then passes through the radiator, where it is cooled by the rapid flow of air. The cooled water then returns to the engine to pick up more excess heat. So to put it simply: the radiator cools the water which cools the engine.
They shake their bodies to get rid if excess water and then lay in the heat of the sun to dry off.
When one gets a heat cramp, they get muscle spasms due to the excess loss of salt and water. With a heat stroke, one will suffer heat exhaustion and heavily sweat, feel nauseous, or lightheaded.
