How do dogs drink Water? Many people may laugh when they see this question, thinking that this question is like asking why 1+1=2 is so boring, but we do know how dogs bring water to their mouths. ?. It turns out that dogs drinking water is not as simple as it seems to us, and their tongues play a crucial role in the process of drinking water.
Scientists from Harvard University used ultra-high-speed cameras to reveal the mystery of dogs' drinking water. When the high-speed cameras filmed animals drinking water at close range, the researchers saw that the dog's tongue would bend backwards, like a reflex. Pour the water into a ladle. However, when viewed from a distance, this spoon function is nothing more than an illusion. Most of the water does not actually enter the dog's mouth, but slides down into the bowl.
Researchers found that the dog's tongue is not a ladle structure, but acts as a sticky whip that sticks the water to the tongue and rolls it into the mouth.
Because the time when the dog's tongue is bent backwards greatly reduces the area of contact with the water, and when the dog's tongue is retracted quickly, a water column will be drawn from the water surface and penetrate the dog's tongue. , then close your mouth and you can drink water. And all this happened in a very short period of time, so ordinary people did not easily discover it.
Therefore, dogs do not drink water by bending their tongues or sucking them as many people think. Instead, their tongues are filled with a kind of stickiness that can stick the water into their mouths. In addition, it seems that what we usually take for granted is not necessarily correct, so caring for dogs cannot rely entirely on one's own subjective judgment.
