Why do dogs have whiskers?

Dogs need to have their senses sharp, to be alert all the time, and to be prepared for any danger. Their senses are diversified and sharper than the ones of humans. One of the important senses is the one of smelling. The whiskers of the dog help him to “pick up” smells from the air, and to identify the difference between those. Another role of whiskers is for touching. The dogs touch objects with their whiskers, determining the consistency and the special characteristics of the object. If you want to cut the whiskers of your dog to look more interesting, just forget about it. How would you feel if you would not be able to smell or taste?
