What Are Dog Whiskers Called?
Dog whiskers are special hairs that are called vibrissae. They are also known as “feelers,” even though dogs cannot actually feel them.

The whiskers of a dog vary with size and breed. Most dogs will have a few whiskers above the eyes and rest around their muzzle and chin. The muzzle whiskers have a special term: they are called Mystacials.
These are of different sizes and usually point away from their face. Structurally, the whiskers are stiffer and are limited to the region around their nose. Whiskers on a dog grow from the same hair follicles as their fur. However, these hairs are more tactile and do not serve the purposes of protection from weather and other reasons why dogs have fur.

A dog will communicate with other dogs and animals through their whiskers. So reading the whiskers can help understand the emotional situation of a dog. For instance, cats and dogs understand each other through the movement of their whiskers.
Dog whiskers are one of the most sensitive parts of their body. It responds to the slightest touch. This is why a dog will make use of its whiskers for protection. The whiskers over a dog’s eyes flick away dust particles or rain drops. The ones around its muzzle protect them from bushes, thorns, and other objects that can harm them.
When a dog is indoors, the whiskers will help them go around the furniture instead of bumping into them. Since whiskers have sensory nerves, it helps the dog understand what they need to avoid in their surroundings, protecting them from accidents.
