Dogs are the most loyal companions of humans. Many people keep them at home. Many people are very interested in various aspects of dogs. Many people know what cats’ whiskers are used for, but many people don’t know the function of dog whiskers. If you want to know, just read here!
A large number of nerve endings are distributed at the roots of a dog's beard, which allows the dog to judge objects more sensitively; the left and right whiskers of the dog also have the function of measuring the width of the body. They can use their whiskers to judge whether they can pass through narrow places; the whiskers can help them maintain their own balance, which is similar to the function of a dog's tail.
A dog's beard is a special hair that has a biological somatosensory effect. It can sense external stimuli and changes in the surrounding environment, including visual aids. It is equivalent to a detector that can feed back various information to the dog at all times and remind the dog whether there are obstacles or prey around it.
