Whiskers are definitely adorable, but do they serve a purpose for your dog? Some groomers shave them, but this can actually be slightly detrimental. What exactly are whiskers for, and should they be left alone?
The Function of Whiskers on Dogs
Scientifically, whiskers are known as vibrissae. Their function is to help your dog feel their way around their environment. If you’ve noticed, whiskers are thicker than any other type of hair on your dog’s body. They’re also embedded more deeply into the skin, and the base of the hair is loaded with sensitive touch neurons that react to touch.
What other animals have functional whiskers?
How Do We Know What Function Whiskers Serve?
Various scientific studies have found that 40 percent of a dog’s touch function is dedicated to the face, especially in the upper jaw where the majority of the whiskers are located. Brain scans show that each individual whisker is assigned to a particular location in the brain. This means that each whisker has its own unique function!
Science is great. But what are these whiskers doing?
Whiskers are an early warning system that alert dogs that something is near their face. The way your dog’s eyes are situated on their head means their vision isn’t as good as yours because their muzzle impedes their vision, so the whiskers prevent them from running into walls, furniture, or other objects.
The whiskers are also an aid in locating things like their toys. Scientists say it’s similar to how a vision-impaired person uses a cane. The muscles that control the whiskers shift the hairs forward when the dog is coming up on an object. They “whisk” (thus the name “whiskers”!) or vibrate, stimulating the brain to move the head towards the object and brush the whiskers against whatever surface is being approached. This helps the brain determine the shape and surface of what’s near their face. Dog see things better from a distance, so these whiskers are essential.
What Happens When Whiskers are Shaved?
If whiskers are removed, your dog has difficulty seeing in low light conditions and they’re more likely to bump into things. If your dog goes to a groomer, reiterate that their whiskers need to stay intact and not to shave them off.
Whiskers are an essential part of your dog’s ability to be active. They don’t require any sort of maintenance, so for the sake of your dog, just leave them alone.
Hi, I’m Jacob. I’ve been a professional blogger for over 6 years and in that time I’ve written countless blogs that have reached millions of people. I am a DVM by profession but all you need to know is that I LOVE DOGS!
SDO started way back in 2015 on a whim. I’d read a couple of dozen blogs online while searching for the best products for my pup and the amount of misinformation online from unqualified sources giving potentially harmful advice shocked me. Then suddenly it hit me, hey, I can do this too! And I can do this RIGHT! Without even knowing what a blog was or how it makes money. I jumped right in to share the years of knowledge I have of dogs with the world.
Within a few months I realized that people were reacting extremely positively to my blogs. My website had taken off and I would receive countless emails from happy dog owners telling me how my website was a God-send for them and their pups were doing so much better after they followed my advice. I would get so many questions as well, and in my attempt to consolidate and answer all the questions I would get from my readers, my blog has evolved to the website you see today. Over the years I encouraged my good friend Tina who is also a DVM to share her experiences and better guide the people who read us. By the Grace of God we now reach close a million people a year and we get such a warm feedback on how we have made life easier for new dog owners all over the globe.
As a dog owner only you would know the feeling you get when you come home at night and you pup is there at the door wagging their tail in sheer joy. The bond a person and their dog share can not be explained in mere words. Yet dogs are like children, and they need to be cared for and trained, and that’s why Smart Dog Owner exists, to give you the precise and exact information that you seek about your dog. No matter how minute that detail is, chances are we will be there to help you out! As someone who has raised 7 of her own dogs. Jacob will always help you out.
