Did you know that in addition to having excellent hearing and smell senses, dogs also rely heavily on their whiskers to help them navigate and comprehend their surroundings? Long, dense hairs called whiskers, or vibrissae, are found on the chin, above the eyes, and on the muzzle of dogs. Dogs use their whiskers to sense changes in the air currents around them, which is one of their principal purposes. These exceptionally sensitive hairs enable a dog to sense its surroundings and navigate in the dark by detecting even the smallest movements. This is particularly helpful while hunting or exploring new areas.
