Like cats and other animals, dogs have whiskers that stick out from the sides of their muzzle. Technically, they aren’t whiskers – they’re called vibrissae, which comes from a Latin word “vibrio” that means to vibrate. A dog’s whiskers are actually highly tuned, multi-functional, sensitive sensory hairs they need and use every day to perform specific functions that help them move around in their world.
Dog whiskers are found on both sides of their muzzle, as well as on the forehead above the eyes, on their chin and above the upper lip. As puppies grow, the whiskers are among the first hairs to develop. Unlike the neatly arranged 12 whiskers in four rows on each side of a cat’s face, dog whiskers are more varied in their pattern depending on their breed and genetics.
Whiskers are twice as thick and coarser than regular dog hair. Their roots are set three times deeper and packed with nerves and blood vessels that make each individual whisker a super sensitive receptor to movement. Air moving it or objects brushing against it causes the whisker to vibrate and stimulates the nerves. Dog whiskers are as sensitive as our fingertips. Whiskers play an important role in helping dogs understand and move through their environment.
