Laika’s already going grey, though she’s 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 there’s a couple different reasons as to why some dogs go grey early while others don’t 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 DogsThe premature greying I’m talking about with Laika is sometimes called geriatric greying, and it usually starts around the muzzle. It’s the greying that’s associated with the aging process, the same one that happens to humans. There’s another type of greying that certain breeds go through called progressive greying. It’s 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 it’s 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.
The Influence of Genetics On Going GreyGenetics is a big influence in premature greying, in both dogs and humans. The pigment cells that give hair it’s youthful color are called melanocytes, and when they die off or grow incorrectly greying starts to occur.
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 Influence of Stress in Premature Greying in DogsWe’ve 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:
The study did not find any predictors of premature greying when looking at a dogs age, size, sex or spay/neuter status.
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.
A Grey Muzzle Doesn’t Always Indicate an Older DogBecause of all the variables associated with coat colors a dog’s grey muzzle isn’t always an accurate way to estimate age. Dogs as young as 2 can have a lot of grey around their muzzle and eyebrows, though it’s often associated with dogs in middle to old age. The condition of a dog’s teeth can usually give a more accurate indicator of a dog’s age, though it’s 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 dog’s 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 it’s 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.

Researchers at Northern Illinois University studied about 400 dogs between the ages of 1 and 4-years-old.
What dog breeds go GREY early?Some breeds are predisposed to going gray early
This is called “progressive graying” and is caused by a dominant gene that especially affects long-haired breeds. Poodles, bearded collies, and certain sheepdogs are typical examples of dogs with this particular gene.
At what age do dogs start getting gray hair?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.
How can I stop my dog from going GREY?Gradual exposure: Control the dog's exposure to a scary thing and reward him for being calm. For example, play a CD of fireworks very quietly in the background, and when a noise phobic dog is calm, give him a treat. Your body language: Keep yourself relaxed so the dog doesn't read your anxiety.
