Do Dogs’ Whiskers Gray With Age? The Truth About Canine Aging


Dog whiskers, also known as vibrissae, are thick, specialized hairs that grow around a dog’s face, mostly on the muzzle above the nose and below the eyes. Whiskers serve important sensory functions, acting similarly to human fingertips. They are highly sensitive to touch and movement, helping dogs detect objects and navigate their surroundings. While many people believe that trimming whiskers is harmless, vets advise against this since it impairs a dog’s ability to perceive their environment.

As dogs age, their whiskers may start turning grey or white just as the hair on their heads does. This brings up the question of whether dog whiskers turn white with age due to the same mechanisms as facial aging and greying in humans. In this article, we will take a closer look at the anatomy and functions of dog whiskers, examine whether they change color as dogs get older, and provide tips for caring for aging whiskers.

Anatomy of Dog Whiskers

dog whiskers contain blood vessels and nerves branching into follicles at the base of each individual hair.

Dog whiskers are primarily made of keratin, which is the same material found in dog fur, claws and hair. The average dog has about 12 whiskers on each side of their muzzle ( Dog whiskers contain a complex network of blood vessels and nerves that branch into a structure at the base of each individual whisker called a follicle ( The nerves provide sensory information to the dog about the movement and position of their whiskers, helping dogs gather spatial information about their surroundings.

Functions of Whiskers

A dog’s whiskers, known as vibrissae, serve several important functions. Whiskers aid dogs with navigation and spatial awareness. The whiskers are highly sensitive tactile hairs that act like antennae, detecting information about the dog’s surroundings. When whiskers brush against objects, they send sensory signals to the brain that provide details about location, distances, shapes, and movements. This helps dogs safely navigate through their environment, even in total darkness.

Whiskers also help dogs detect air currents and wind patterns. The fine hairs of the whiskers can pick up the slightest changes in airflow. This assists dogs with sensing approaching objects or dangers in their vicinity. It also provides information about weather conditions. Additionally, whiskers protect a dog’s eyes by alerting them to obstructions that are too close to the face.

Overall, a dog relies heavily on its whiskers for sensory input about its immediate environment. The whiskers provide spatial and navigational guidance, as well as detecting subtle air currents and nearby objects or obstacles. This is why it is very important not to trim or damage a dog’s sensitive whiskers, which serve such vital functional purposes.

Do Whiskers Turn White with Age?

whisker greying often correlates with senior status in dogs, but the onset and degree varies based on genetics, diet, health and other factors.

Whisker whitening is a common sign of aging in dogs. As dogs grow older, their whiskers often start turning white or gray. According to this source, white whiskers indicate a lack of pigment in that area of the body, while black or brown whiskers contain more pigment. Pigment loss can occur naturally with age.

However, some argue that not all dogs experience whisker whitening with age. According to this source, genetics plays a major role. Some dogs are predisposed to greying early, while others may retain their dark whiskers well into old age. Diet, environment, and health may also impact pigment retention.

While whisker whitening often correlates with senior status in dogs, it doesn’t appear to be an inevitable part of the aging process. The onset and degree of whisker greying can vary substantially based on the individual dog. However, noticeable whisker whitening in a middle-aged or senior dog is usually a normal sign of aging.

Whisker Colors

Dog whiskers come in a variety of colors that are determined by the dog’s genetics and coat color. Common whisker colors include:

  • Black – Many dogs have black whiskers that match their black fur or noses. This includes breeds like Poodles, Schnauzers, Scotties, Yorkies, and more.
  • White – White whiskers are found on dogs with white or light-colored fur, such as Bichon Frises, Malteses, Poodles, Samoyeds, and West Highland White Terriers.
  • Brown – Dogs with brown, chocolate, or liver-colored coats will have matching brown whiskers. This includes Dobermans, Labradors, Cocker Spaniels, and others.
  • Red – Red whiskers match the reddish fur seen on Golden Retrievers, Irish Setters, and other breeds.
  • Mixed – Multi-colored dogs like Beagles, Australian Shepherds, Collies, and Bernese Mountain Dogs may have a mix of white, black, brown, and gray whiskers in their coat.

So in summary, dog whisker colors are primarily determined by the dog’s genetic coat color and patterns. Dark-colored dogs have dark whiskers, while light dogs have light-colored whiskers matching their fur.

Health Indicators

A dog’s whiskers can provide insight into their health and wellbeing. Changes in the feel, appearance, or quantity of whiskers may reflect underlying illness or nutritional deficiencies.

changes in the quantity, appearance or feel of a dog's whiskers may signal underlying illness or nutritional deficiencies.

Brittle, broken, or missing whiskers can signal issues like malnutrition, stress, metabolic disorders, or immune disorders. Dogs require certain vitamins and nutrients like biotin and fatty acids for healthy whisker growth. Deficiencies may cause whisker thinning or fragility. Diseases affecting hormone balance, like hypothyroidism, can also impact whisker health.

Whisker loss may occur alongside fur loss and can point to skin problems like infections, parasites, or allergies. Autoimmune diseases, where the immune system attacks the body’s own cells, are another potential cause.

If your dog’s whiskers suddenly become brittle or fall out, schedule a veterinarian visit. Diagnostic tests can help identify underlying issues. Once the cause is found, your vet will recommend appropriate treatment to restore your dog’s health and whiskers.

Grooming Considerations

Proper grooming is an important part of caring for your dog’s whiskers. While some owners choose to trim their dog’s whiskers, this controversial practice has both pros and cons to consider.

On the pro side, trimming whiskers may keep them from getting dirty or matted with food particles. However, according to Dog Whiskers: Everything You Need to Know, trimming or plucking whiskers is not recommended as it may be painful and negatively impact your dog’s spatial awareness and sensory perception. Whiskers contain many nerve endings that help dogs sense objects around them.

To keep your dog’s whiskers clean without trimming, gently wipe their muzzle after meals with a damp cloth. Check for any debris caught in the whiskers and carefully remove it. Regular brushing will also help whiskers stay tangle-free. Be extremely gentle, as the area around the whiskers is sensitive.

Bathing and shampooing should only be done as needed, as over-washing can dry out the skin and follicle area. Use a mild dog shampoo and avoid getting soap directly in your dog’s eyes. Thoroughly rinse whiskers after washing to remove any residual shampoo or dirt.

Overall, focus on gentle daily grooming to keep your dog’s whiskers clean and healthy without resorting to trimming. Proper care will help preserve their sensory function.

Caring for Aging Whiskers

As dogs age, their whiskers can become more prone to breaking and sensitivity. Here are some tips for keeping your senior dog’s whiskers healthy:

gently brushing whiskers daily and monitoring for redness or irritation can help care for aging dogs' sensitive whiskers.

Gently brush whiskers daily with a soft toothbrush or cloth to remove dirt and debris. Avoid harsh tugging or pulling. Use a mild dog-safe shampoo when bathing to avoid drying out the follicles (1).

Monitor for red, inflamed or irritated areas around the whisker beds. This can indicate an infection or condition requiring veterinary attention (2).

Avoid trimming aging whiskers, as this can cause disorientation and anxiety in senior dogs. Whiskers provide spatial awareness and sensory information (3).

Use a night light or keep lights dim if your dog seems more sensitive to light as their vision declines. Protecting their eyes can help reduce whisker sensitivity as well (1).

Try a raised dog food bowl to prevent whiskers from touching and dragging in the bowl. This minimizes irritation during eating (2).

Talk to your veterinarian if you notice rapid whisker shedding or breakage. Certain nutritional deficiencies or illnesses can impact whisker health (3).

With gentle handling and proactive care, you can help ensure your senior dog’s whiskers remain healthy into their golden years.

When to Seek Help

In most cases, whisker changes in aging dogs are harmless. However, there are some signs that could indicate an underlying health issue requiring veterinary attention:

Excessive or rapid whisker loss, especially if accompanied by other hair loss or skin problems, could signal conditions like mange, ringworm, or hormonal disorders. Seek prompt veterinary care if you notice extensive whisker shedding.

Inflammation, redness, pus, or scabs around whisker follicles may indicate infection. Have your vet examine any irritated whisker areas.

Sudden whisker loss on just one side of your dog’s face could result from nerve damage or injury. See your vet to identify potential causes.

If your aging dog’s whiskers turn brittle and break easily, discuss supplements or diet changes with your vet to improve coat health.

Schedule a senior wellness exam with your veterinarian to identify any health issues that could impact your aging dog’s whiskers. Your vet can recommend treatment options to restore whisker growth and health.

While whisker aging is normal, numerous or progressive changes may suggest underlying disease. Check with your vet if you have any concerns about your senior dog’s whiskers.


As we’ve explored, dog whiskers serve important sensory functions and can change colors as dogs age. While white whiskers are common in senior dogs, other factors like genetics, breed, and environment also influence whisker pigmentation over time. Keeping your dog’s whiskers clean and monitoring for abnormalities is part of regular grooming and health checks. Overall, white whiskers alone are not a major cause for concern in an otherwise healthy older dog. They are a natural sign of aging that do not require intervention beyond basic care and attention.

In summary, key points from our discussion include:

  • Whiskers help dogs sense their surroundings and spatial orientation.
  • Many dogs naturally develop white whiskers as they age, similar to graying hair.
  • Breed, genetics, and environment also impact whisker color over time.
  • Look for whisker breakage, loss, or redness as potential health indicators.
  • Gently clean aging whiskers while grooming and check for issues.
  • White whiskers themselves don’t need treatment in healthy dogs.

While whisker greying is a normal part of the aging process, be attentive to any concerning changes. Consult your veterinarian if you notice significant whisker loss, damage, or changes in your senior dog. With regular care and checkups, aging dogs can live happily with their distinguished white whiskers.
