referring to the properties of water...

As mentioned above, humans have sweat glands over their entire bodies; the only place dogs (and cats, and many other animals with fur over their whole bodies) can get rid of excess heat is through the tongue. By the way, sweating/panting is NOT a means of getting rid of excess water; it is a way of getting rid of heat. We do this because of the process of evaporation. In changing from liquid to vapor, the water absorbs heat from the surface on which it is laying. Actually, most organisms do not want to get rid of excess water; they need to conserve it, but on very hot days animals "spend" the water to achieve the cooling.

Both are ways of getting rid of excess water. However those poor dogs lack sweat glands so they just hang out their tongues to let their breath evaporate the water for cooling.

sweating is our bodies natural way of cooling ourselves off... but since dogs cant sweat they pant to cool themselves off

This is the same technique I have taught over 138,000 men and women in 157 countries to successfully treat their excessive sweating condition over the past 7 years!

Us humans have sweat glands which cover our entire bodies. Dogs only have them in their mouths.
