Dogs with long whiskers on their chins can sense the vibrations of water flow

Dogs generally have a few stiff hairs in the middle of their chins, similar to beards, and some grow on a mole. There is a folk saying: "The one with one beard on the chin is called dragon beard, which is good at tracking; the one with two beards is called tiger beard, which is good at biting; the one with three beards is generally lazy and is used to look after the house; the one with four beards is the rarest and can bring prosperity to its owner. , bring wealth to the owner. "It's just an entertainment statement. In fact, a dog’s whiskers can be used to sense weak vibrations, including changes in airflow and water flow. This is why when a dog swims for the first time, he knows to keep his head up and keep it above the water. It is the whiskers under the chin that sense the vibration of the water flow and then determine the position of the water surface.
