Why Is My Dog's Muzzle Hair Turning Gray?

As a pet parent with an adopted dog, you might not know your dog's exact age. And now his hair, especially around his muzzle, is turning gray. Does a gray muzzle mean he's becoming a senior dog? Or is it a sign that something is wrong?

Gray hair on a dog's face and around his muzzle is a natural occurrence as he ages just like turning gray is a natural occurrence for humans. Because dogs age faster than humans, they turn gray sooner than their pet parents. And just like humans, some dogs turn gray much earlier in life than others.

Behavior and Health Link

While typically a sign of an aging dog, a gray muzzle can also be found in dogs as young as one year old. A study of 400 dogs, published in Applied Animal Behaviour Science, discovered that dogs that experience high levels of anxiety, are impulsive or have fearful responses to strange people, animals and noises are linked to premature graying not much different to when you hear people say things like, "you're the reason I am going gray."

A graying muzzle may also indicate a health issue. For instance, premature graying of the muzzle is one sign your dog might have hypothyroidism. Because it could be health-related, you should consult with your veterinarian if your dog starts graying.

Senior Years

Typically, a graying muzzle or face is a sign your dog is entering his senior years. Typically, dogs enter their senior years between the ages of seven and ten, but depending on your dog's size it might be even younger. For instance, giant breed dogs (those that weight 91 pounds or more) can be considered senior by the time they turn five, according to the American Veterinary Medical Association (AVMA). Small and medium breeds (up to 50 pounds) can be considered a senior at around age seven. Genetics plays a large roll in the graying process of your dog as certain breeds or lineages have a predisposition for graying earlier than others. It's also a lot easier to notice a gray muzzle on a dog with darker hair than say a West Highland white terrier.

Dogs that have reached their senior years may benefit from switching to a senior dog food. While it doesn't reverse the causes of graying in your dog, the best senior formulated dog foods offer a nutritional formula that works to ease the effects of aging. For instance, Hill's Science Diet Youthful Vitality was developed with the changing biology of pets ages seven and above in mind. The breakthrough nutrition found in the Science Diet food is made with Hill's proprietary recipe of natural ingredients including fruits, vegetables, fatty acids and antioxidants plus added vitamins, minerals and amino acids all of which work together to fight the effects of aging. Its formula is designed to help with brain function, energy and vitality and healthy immune and digestive systems. It also includes essential fatty acids that promote a coat with increased shininess and softness.

Going gray for whatever reason might give your dog a new look. But he will still thrive on the same love and attention he's always wanted from you!

Why Do Dogs Go Grey Early?

Last updated on November 1, 2023 By Puppy Leaks 29 Comments

Laikas already going grey, though shes only 3 years old. Looking back all of my dogs went grey eventually, but it never started quite that early.

So it got me wondering why do dogs go grey early anyway? It it all genetics? Is it stress related? And why do some dogs go grey much earlier than others?

Why Do Dogs Go Grey Early?

Is your dog doing grey around the muzzle? Just as it is with humans theres a couple different reasons as to why some dogs go grey early while others dont grey much at all.

Two major factors come into play when it comes to dogs going grey stress and genetics. Dogs with high levels of psychological stress or anxiety have been found to grey earlier, and the cellular stress that causes grey hairs has a genetic component in dogs.

On average most dogs start going grey around 5 years old, though some start going grey before the age of 2. Greying in dogs can occur anywhere, but it tends to be most prominent on their muzzle.

Geriatric vs Progressive Greying in Dogs

The premature greying Im talking about with Laika is called geriatric greying, and it usually starts around the muzzle. Its the greying thats associated with the aging process, the same one that happens to humans.

Theres another type of greying that certain breeds go through called progressive greying. Its caused by a progressive greying gene that causes their coats to turn grey or silver. This type of progressive greying is attributed to chromosome 25, though the gene itself has not been found.

Some breeds, such as Poodles and Bearded Collies, have the greying gene that causes their entire coat to turn silver. Because the progressive greying gene is dominant its also seen in some mixed breeds, especially in the UK where Bearded Collie & terrier crosses are common.

What Causes Premature Greying in Dogs?

Though the specific gene that causes premature greying has yet to be found, experts say that cellular stress is what causes grey hairs. Over time we create less melanin, the black or brown pigment that occurs in the hair, skin & eyes of humans & animals.

Scientists traced the loss of hair color to the gradual dying off of adult stem cells that form a reservoir that spawns a continuous supply of new pigment-manufacturing cells, called melanocytes, that give hair its youthful hues. Science Daily

The Influence of Genetics On Going Grey

Genetics is a big influence when it comes to premature greying, in both dogs and humans. The pigment cells that give hair its youthful color are called melanocytes, and when they die off or grow incorrectly greying starts to occur.

Cell survival in general is influenced by an anti-death gene known as Bcl2. So the study included mice without the gene. Turns out they lose their melanocyte stem cells shortly after birth and turn gray quickly. Could be, Fisher said, that people who gray prematurely have mutations that knock out Bcl2. Live Science

The pigment cells responsible for our hair color undergo levels of cellular stress that lead to greying. When they die off or develop in the wrong part of the hair follicle our hair goes grey.

The blame lies on genotoxic stress, or stress from mutagens that can cause damage to DNA, such as ultraviolet light. The researchers found that this cellular stress diminishes the supply of melanocyte stem cells (MSC) cells in hair follicles that are responsible for making the pigment-producing cells that give hair its color. Live Science

The Influence of Stress in Premature Greying in Dogs

Weve all heard that stress can cause premature grey hairs, but can the same be said for our canine companions? Scientists are trying to figure this out, but early research points to yes.

One recent study surveyed the owners of 400 dogs aged 1-4 who were showing signs of premature greying. Based on answers provided researchers concluded that psychological stress & anxiety may indeed play a role in the premature greying of young dogs.

Researchers were able to predict premature greying in dogs that exhibited anxious or impulsivity behaviors at home. These include:

Fear of noises
Fear of unfamiliar people or animals
Jumping up on people (being impulsive)

The study did not find any predictors of premature greying when looking at a dogs age, size, sex or spay/neuter status.

The current dog study by King and colleagues finds that premature graying could link up with anxiety, impulsivity, or fear issues, which are not fabulous if you are a dog. About That Premature Greying, Scientific American

Can Medical Issues Cause Greying?

In a few instances your dogs early graying could be caused by a medical issue. If you suspect your dog has a medical problem please consult your veterinarian.

One of the main symptoms of hypothyroidism is multiple hair changes which includes hair loss, coarseness, dark skin pigmentation, and premature greying of the muzzle.

Clinical symptoms of the disease include hair loss, premature graying of the muzzle, hair coat dryness, retarded hair growth, and dark skin pigmentation. St. Georges Veterinary Hospital

A Grey Muzzle Doesnt Always Indicate an Older Dog

Because of all the variables associated with coat colors a dogs grey muzzle isnt always an accurate way to estimate age. Dogs as young as 2 can have a lot of grey around their muzzle and eyebrows, though its often associated with dogs in middle to old age.

The condition of a dogs teeth can usually give a more accurate indicator of a dogs age, though its not an exact science because of outside influences. Estimates are made by the amount of tartar buildup and how worn down the incisors are. A dogs lower incisors tend to remain uneven until a dog reaches middle age.

Though Laika has premature greying her uneven lower incisors are a more accurate indication of her age.

So When Does a Dog Normally go Grey?

On average its around 5 years old, but varies greatly. Premature greying is rarely cause for medical concern, but as always if you suspect something may be wrong please consult your veterinarian.

When it comes to going grey early dogs are just like us. Some go grey really early, some never will, but most are somewhere in the middle. Premature greying is just an aesthetic thing, and rarely cause for concern.
