Do Dogs Whiskers Grow Back? Physiology of Dog Whiskers

The whiskers on a dog’s face are one of its most distinguishing features. These thick hairs sprout from the face of all dogs and most mammals. While cats have a distinct pattern in their whiskers, dogs have a wider range of whiskers.

They are located on both sides of their muzzle, under their chin, and above their eyes. Every dog has a distinct whisker pattern.

While many people think of whiskers as a cute physical feature, they do much more than just improve your dog’s appearance.

Whiskers assist your dog in navigating the world and can even warn your dog of impending danger. Needless to say, whiskers are an essential part of your dog’s anatomy. So, what happens when they are severed? Do dogs whiskers grow back?

There’s no need to be concerned if your dog’s whiskers are clipped. Whiskers, like other hairs, go through a growth cycle. They will fall out on their own over the course of your dog’s life and regrow with time.

Unfortunately, there haven’t been many studies to determine how quickly whiskers grow back. Whiskers are thought to grow at the same rate as the rest of your dog’s hair. It usually takes a few months to recover to the original length.

Many dogs require up to 16 weeks or more. Everything is dependent on your dog’s breed and overall health. Because hair growth differs from dog to dog, there is no way to be certain. If your dog’s whiskers fall out or are cut, just be patient and wait.

Do shaving the dog’s whiskers harm him?

It’s a common misconception that dogs experience pain when their whiskers are clipped. Despite their intricate anatomy, your dog’s whiskers do not cause physical pain when cut. Nerves are not found in the hairs themselves. It may feel strange as it is cut, but it will not hurt.

Having said that, you should never pull or twist the whiskers. Remember that the nerves are all contained within the follicle. Pulling causes follicle stress and trauma, resulting in discomfort and possibly pain.

Plucking these hairs can be extremely painful, and they seem to attract small children, so you’ll need to keep an eye on them until they learn not to touch them. When their whiskers are pulled, dogs can become aggressive.

The Physiology of Dog Whiskers

Whiskers are distinct from the standard fur that covers your pup’s body. They are significantly thicker. Not only that, but they are frequently longer. They protrude from your dog’s face.

Your dog’s whiskers may change color depending on their breed and color pattern. Aside from physical differences, whiskers grow from distinct hair follicles. They are three times deeper rooted than normal hair.

Under the Root

“Vibrasse” is the technical term for whiskers. This is due to the fact that whiskers are sensory hairs that can detect even the most subtle vibrations. They are capable of detecting even minor changes in the air. This is why dogs perceive their surroundings better than humans.

When the whiskers move, the vibrations are picked up by follicle receptors.

As previously stated, whisker follicles differ greatly from standard follicles. They’re densely packed with blood vessels and nerves. All of those nerves are linked to parts of your dog’s brain that deal with touch information.

Whiskers are similar to human fingertips. We use our fingers to gain a better understanding of our surroundings. The information we gather with our fingertips is used to determine the size, texture, temperature, and other properties of an object. The same is true for a dog’s whiskers.

While they may appear to be the same, there are several types of whiskers. They can be identified by their position on the face. All whiskers serve the same basic purpose: to assist your dog in understanding its surroundings. Some whiskers, on the other hand, have very specific functions.

Whiskers Mystacial

Mystacial whiskers are similar to cat whiskers and are probably what most people envision when they think of whiskers. These are long hairs that protrude from the snout’s left and right sides. These whiskers provide tactile information about surfaces near the mouth and are probably most useful when many breeds like to stick their heads into holes.

Mystacial whiskers most likely assist your dog in more accurately navigating the food bowl and alerting the dog when something is in range of its jaws, which can be especially useful during combat. If you trim these whiskers, you may notice a sloppy dinner area and the dog may bump its snout against more surfaces. It may also make it vulnerable in battle.

Whiskers Supraorbital

Supraorbital whiskers are located directly above the eyes and resemble eyelashes. These are useful when your dog sticks its head in a hole or tries to navigate narrow passages because they protect the eyes from incoming objects. Because danger will reach the whiskers before the eyes, these whiskers will also help protect the eyes from danger approaching from behind. Because the eyes are extremely sensitive and vulnerable, cutting these whiskers is especially dangerous.

Tufts Interramal

The interramal tufts can be found under the dog’s chin. These whiskers vary in length from breed to breed, but they are always present and help your dog detect objects below its head. Water retrievers benefit from interramal tufts because they help your dog determine where the water level is so they don’t drown. They will also assist brush hunting dogs who keep their heads low to the ground while tracking prey or running through thick brush. They will also assist your dog in navigating the ground when it is resting its head. Cutting these whiskers can make it difficult for your dog to sleep, and allowing your dog to swim without Interramal tufts can be dangerous.

Whiskers Genal

The cheeks, which are the widest part of the dog’s face, have genal whiskers. Your dog is probably using these whiskers to keep its head from getting stuck, especially when chasing a rabbit into a hole. The genal whiskers are also likely to alert your dog when it is approaching a wall or other surface, and they are likely to be especially useful when walking through doorways. While removing mystacial whiskers may cause your dog to bump its nose more frequently, removing genal whiskers may cause your dog to bump its head more frequently, potentially resulting in serious injury.

Your canine companion’s whiskers do a lot to keep them informed about what’s going on around them. While canines have the same senses as humans, they function very differently.

They do not perceive or hear the world in the same way that we do. Whiskers bridge the gap and provide your dog with numerous additional benefits that we could never have imagined.

#1. Protection

Their supraorbital whiskers, which are located above their eyes, provide excellent protection. When your dog sniffs around in the bushes, leaves and branches will brush up against his whiskers. This communicates with your dog’s brain.

That signal essentially instructs them to blink or close their eyes. The whiskers are the first line of defense against ocular damage.

#2. Navigation

Have you ever wondered how dogs can navigate so well in the dark? It’s not because they have extraordinary night vision. Their whiskers play an important role in assisting them to avoid obstacles and safely arrive at their destination.

The whiskers are sensitive enough to detect air changes as they approach walls or furniture. They can even assist canines in getting through tunnels in the wild.

#3. Aid with vision

Whiskers can also assist your dog in “seeing” blind spots around them. Because of the position of their eyes, they cannot see a treat placed on the ground in front of them. They will, however, be able to locate it thanks to their mystacial whiskers and interramal tufts under their chin.

When you throw your dog’s favorite frisbee or fetching ball, the same mechanics are at work. While they can use their hearing to get a general idea of where the item landed, they rely on their whiskers and sense of smell to pinpoint its precise location.

Frequently Asked Questions

#1. How long does it take for a dog’s whiskers to regrow?

Your dog will adjust to life without whiskers in a matter of days, and you may notice them returning in as little as two weeks, which is much faster than cats, which can take up to two months to regrow. Plucked whiskers, on the other hand, can take much longer to grow and may never grow back.

#2. Does a dog lose its balance if it lacks whiskers?

Many people notice strange behavior from their pets that can resemble a loss of balance, so it’s an urban legend that dogs lose their balance if their whiskers are cut. However, the strange behavior is more likely to be caused by disorientation as a result of losing one of its senses. Depending on which whiskers are missing, it may also run into a wall or miss its food bowl.

#3. Is it necessary to trim your dog’s whiskers?

You should never intentionally trim your dog’s whiskers because they are an important part of how your dog perceives the world. This would deprive them of a significant portion of their sensory perception.

Over time, your dog will adjust to the change. However, there may be times when they have difficulty going about their daily routine.

It’s best to leave them alone and let your dog use their whiskers as intended.

#4. Do dog groomers trim the whiskers?

Groomers are frequently asked to trim whiskers. Indeed, many breeds have grooming standards that include a shaved face. Trimming hair around the whiskers is difficult and inconvenient. As a result, most groomers will simply shave over the whiskers.

It isn’t ideal, but it isn’t the end of the world either. Your puppy will adjust, and his whiskers will grow back over time.


So, do dogs whiskers grow back? Although they grow back quickly and are not particularly harmful to your dog, we never recommend trimming or plucking your dog’s whiskers. Your dog relies on these tools to navigate its close-range environment and may sustain injuries if they are not present. Without these whiskers to provide feedback, your dog may withdraw and refuse to be a pet. Even a slight trimming can reduce their effectiveness, so we recommend leaving them alone and instructing your dog groomers to do the same.
