The Phenomenon How Dogs Drink
Scientists found out that it is higher physics how dogs drink. They dip their tongue like a cup into the water and put it out very quickly. With this technique the liquid adheres on the tongue and a little water depth is generated.
As soon as this water depth appears the dog kind of bites it of the water surface. This is only possible because the tongue acts in a high speed. The fact that the tongue is shaped like a cup is also the reason why there is always a mess around the bowl because the water in this “cup” splatters out of the mouth.
