Whiskers are long coarse hair rising from your dog’s muzzle, jaw and above the eyes. The hair follicles at the base are loaded with nerves that carry sensory messages to the canine brain. These whiskers act as receptors by responding to external stimuli and transmitting signals to sensory nerves.
Dog Whiskers easily pick up minute changes in air currents and convey to the dog information regarding the size, shape and speed of near by objects, thus helping it to clearly see in the dark. The ability to sense vibrations in the air also helps a pooch to stay away from possible danger. Image: https://www.psychologytoday.com
