All canines, including dogs, have short, sharp hairs around their nose called whiskers. These are crucial physical features that serve an important purpose, much like a cat’s whiskers. Unlike human mustaches, dog whiskers are specially designed to sense their surroundings and help dogs navigate their environment.

As a dog owner, it’s essential to understand the role of whiskers in your pet’s life. They’re not just there for show!

What Are Dog Whiskers Called?

Dog whiskers, also known as vibrissae, are unique hairs that help dogs to perceive their surroundings. These whiskers grow during the fifth week of pregnancy in the mother’s womb. They come in different sizes and shapes, depending on the dog breed. Most dogs have whiskers above their eyes, while the rest are found around their muzzle and chin. The muzzle whiskers are also known as Mystacials.

The Mystacials, which are the whiskers on a dog’s muzzle, vary in size and point away from their face. They are stiffer and are limited to the region around their nose. Unlike fur, which protects dogs from weather, the whiskers are more tactile and serve as a sense organ for the dog.

Lastly, it’s a misconception that dogs cannot feel their whiskers. The whiskers have nerve endings that are sensitive to touch, and they help dogs navigate their surroundings.

What Are Dog Whiskers For?

Whiskers are an essential part of a dog’s physical appearance. But why do dogs need whiskers? Why do they have them only around the face? The reason is simple: The whiskers are responsible for sending early warning signals to the dog’s brain.

Dog whiskers have a lot of nerve fibers located at the base of the originating follicles. This makes them extremely sensitive to touch. The main purpose of dog whiskers is to help them understand where they are going or if something is obstructing their path. Here are some more reasons why a dog needs its whiskers.


Dogs have a poor sense of sight compared to their hearing and smell. They often have trouble seeing objects that are too close. What whiskers do for dogs is act as a navigation system for where they are going and how they need to walk without bumping into something.

The whiskers are a type of sensory organ of their body. They can use these to understand everything around them. If you gently touch a dog’s vibrissae, they will immediately blink and try to get away from your hand. This shows that they can feel an obstruction with the whiskers.


Dog whiskers are also essential to how dogs communicate with humans and other dogs. If you notice your dog has its whiskers elevated, it is a sign that they are excited and happy. Most young dogs have elevated whiskers when they are running around and playing.

If a dog is scared or feels a threat, it will put its whiskers down and the vibrissae around its muzzle will be facing forward. This is similar to any other fight or flight response in mammals where they are preparing for any form of threat.

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.

Do All Dogs Have Whiskers?

All types of dogs have whiskers. From hairless breeds like the Chinese Crested Dog and American Hairless Terrier to the hairiest breeds like Huskies and Saint Bernard, all dogs will have whiskers.

A dog’s whiskers will vary in size, shape, and consistency depending upon the breed. A hairless or curly-haired dog such as a Sphinx will have more whiskers around its muzzle. A more common dog like the Labrador will have whiskers evenly distributed around its face.

Can You Remove Your Dog’s Whiskers?

No, it is not appropriate to remove your dog’s whiskers by trimming them. Although you may think it’s part of grooming, it’s not recommended because it can cause more harm than good.

Removing your dog’s whiskers by trimming them is painful for your dog, just like plucking out hair in humans. Additionally, dogs need their whiskers to survive in any environment. These sensitive hairs help them navigate their surroundings and respond to different stimuli.

If you trim your dog’s whiskers, it can affect their sense of touch, sight, and cause disorientation in their daily activities. Moreover, it can even make your dog more aggressive due to the stress it causes them. Trimming a dog’s whiskers is similar to amputating a functional organ, which is a banned procedure in many countries because it causes so much pain to the animal.
