Do Dog Whiskers Grow Back If Cut Short By Accident?

Written by Wen Duan

Yes, the whiskers will grow back if cut short by accident. 

Whiskers grow like the rest of your dog's hair. They will fall out throughout your dog's life and grow back with time. 

Though your dog will not feel any pain when whiskers are cut, it is best to leave their whiskers alone. You should never intentionally trim your dog's whiskers. 

Whiskers do more than make your pup look fashionable like a beard on a hipster. Whiskers serve a purpose!

Importance of dog whiskers

Whiskers are different from other hairs on your dog's body. They are rigid and embedded deeply into the skin. The base of each whisker has a high concentration of sensitive neurons that produces a reaction with the slightest pressure. 

Whiskers help dogs navigate. 

Whiskers help dogs avoid obstacles. Think of them like the sensors on your new Roomba vacuum that tell it when it's too close to a wall.  

In the wild, the whiskers help get them through small spaces such as tunnels without issues.  The whiskers are sensitive enough to pick up changes in the air as they walk around walls or furniture. 

This helps them in the day time as well as the night time. 

Protects protects their face

Their whiskers not only help them navigate but their supraorbital whiskers also protect their eyes and face as they are sniffing through the bushes, branches, and leaves.

When items brush on these whiskers it lets the dog know to close their eyes or blink. It protects against them from running into anything and poking an eye.

You can see this in action by gently tapping on their whisker. When you tap on their whisker you will see their eyes blink to protect themselves and maybe your dog will turn their head away from the side that is tapped. 

Whiskers help dog see blind spots.

Whiskers senses slight changes in air currents. So your dog's whisker doesn't have to touch the wall in order to know it is there. As a dog approaches a wall, some of the air he stirs up bounces back from the surfaces. His whiskers are sensitive enough to sense the air change and it lets him know that there is a wall there. 

Types of dog whiskers 

Did you know that dogs have more than one type of whiskers and they have their own names? Let's take a look:

Mystacial Whiskers

These are the whiskers that come from your dog's muzzle on top of their lip. 

Genal Whiskers

These are the whiskers on your dog's cheeks. 

Interranmal Tufts

Whiskers that are under your dog's chin. They will be coming out of a mole-like spot. These whiskers provide your dog with the sensory information on what is beneath their head. Your dog can tell how close or far their head is from their food and water bowl. These whiskers also help when they are digging or have their heads close to the ground. 

Supraorbital Whiskers

Whiskers above the dog's eyes. These whiskers protects your dog's eye. An eye can be easily poked or injured by protruding objects such as branches. The moment supraorbital whiskers detects somethings dangerously close to your dog's eye, your dog will blink before they have a chance to be harmed. 

How long does it take whiskers to grow back? 

It varies breed by breed and there is very little information on dog's hair growth rates, but they do grow back with time.

The National Institute Health Center for Biotechnology Information has a research that studied the regrowth hair rates of 11 Labrador retrievers. They clipped the hair and on average it took about 13.6-15.4 weeks for the hair to grow back to it's pre-clipped length.

Since there is very little information on the precise regrowth rates, one can assume whiskers grow back around a close rate to dog's fur which is about 3-5 months.
