can they sweat dogs by tongue?

During summer's dog days, her wet tongue freshens them both as we our sweaty armpits. But, luckily for the dogs, their tongues not perspire really.
Animals with little hair in the body - such as humans, horses and some species of monkeys - cool when sweat evaporates from your skin. For species with long hair, like dogs, sweat would be like putting a coat soaked. For this reason, dogs take the tongue and Pant to cool.
Energy, in the form of body heat, is needed to evaporate the liquid from the surface of the skin or the tongue, explains Jack Boulant, a physiologist heat of the Ohio State University, when the heat evaporates moisture from the surface, the body temperature drops.
After a few years, scientists have discovered that dogs, the system to more regulate internal thermostat, reacts to the heat by pumping warm blood to the tongue, opening the salivary glands and causing a rapid breathing and shallow. As the hot air flows through the trachea and the tongue, help to evaporate moisture, which removes heat from the blood of the dog.
In addition to lower body temperature, this process helps to cool the brain. Blood circulates through the nose and tongue and coldest reaches the brain, which keeps the body which regulates the heat at a temperature lower than the rest of the body. The cooling system works also for races with the short beak, as the Pekingese, which has smaller snout and narrower air passages.
