Far from being a purely cosmetic feature, whiskers is a highly functional set of stiff hairs found on the sides of dogs’ muzzles, which lies embedded deeply into the skin. Each vibrissa has a high concentration of touch sensitive nerves at its base. Working as a device that detects anything near the face, whiskers helps dogs avoid any possible obstacles or objects in their way. Moreover, the protruded hairs protect dog’s face and eyes against damage from an approaching object.
