If you’ve ever brushed your fingers over your dog’s face, you’ll feel the change in the hair around their muzzle and eyes. Or perhaps you have taken your dog to the groomers, and when they came home they were a little disoriented? This is because of the impact that a dog’s whiskers have on its orientation. Unlike a beard or mustache, a dog’s whiskers are important for the way that your dog navigates the world. But why do dogs have whiskers? And why should you never remove them?
What are dog whiskers?
Dog whiskers are known as vibrissae. They grow predominantly around a dog’s muzzle, jaw, and by their eyes and are deeply set into the skin. Unlike the other hair on a dog’s face, the follicles at the bottom of the vibrissae are full of nerve endings that act as sensory messengers to your dog’s brain. You can tell the difference between dog hair and a dog’s whiskers based on how the dog responds to the touch. Be gentle, but if you touch your dog’s whiskers, then you might find that causes them to blink or flinch.
Do All Dogs Have Whiskers?
The short answer? Yes! You’ll find that whiskers are actually particular to every type of mammal, and even some fish, except human beings. In actuality, human beings did have whiskers when we were more like our chimpanzee relatives. Around 800,000 years ago, our DNA was affected, and we incorporated this into our somatosensory cortex. So we do still need to process touch, but it’s become a part of how our brain processes the world.
Why do dogs have whiskers?
Predominantly, a dog will use their whiskers to help them process the sensory information they receive from the world. In general, a dog doesn’t have the most impressive eyesight, and they rely on their whiskers to help them navigate the world. When the dog’s whiskers sense small objects or things that are close, the nerves at the bottom of the vibrissae are stimulated to fill in the brain.In terms of what the whiskers can sense, the dog can process the speed, size, and shape of objects, and whether or not they can fit in certain spaces.
Where do dogs have whiskers?

This means from when they’re very young puppies; dogs rely on their whiskers to help keep the dog safe.
Are Dog Whiskers Like Cat Whiskers?
While they might seem less prominent than a cat’s whiskers, a dog’s whiskers essentially operate the same way – like navigation and safety devices. This kind of information that cats and dogs process from their whiskers is known as proprioception. Proprioception is how a dog creates and gets the awareness of the position and movement of its body within the world.
Whiskers help dogs to hunt
Far from only helping a dog to make its way around the world, whiskers are also fantastic tools for dogs to hunt with. Whiskers allow a dog to recognize what is moving around them, and sensing movements in the air. This allows the dogs to locate the prey, and to pay attention to the environment around them.
Dog whiskers show your dog’s mood
A dog’s whiskers can also show you how your dog is feeling about the world. Each of the little hairs can be pointed directionally – so, when a dog is feeling threatened or uncertain, they flare their whiskers. This changes a dog’s posture which notifies other dogs how they’re feeling, and that they’re on the alert. Whereas when a dog is feeling happy and comfortable, their whiskers are relaxed and not on prime alert.
Can I cut my dog’s whiskers?
When it comes to cutting a dog’s whiskers, it’s important to realize that a tidy appearance is less important than your dog’s comfort.

You might find that having cut a dog’s whiskers leaves your dog feeling disoriented and uncertain. The good news is that they will grow back, but if your groomer has cut them then it’s worth advising they don’t do it again in the future.
