If your Labrador has black spots on its tongue, it's not uncommon. This condition is known as melanosis, a benign growth of melanin-producing cells.
Labradors are prone to melanosis due to their genetic makeup, which can cause an overproduction of melanin. This can lead to black spots or patches on the tongue, lips, and inside of the mouth.
These black spots are usually harmless and don't cause any discomfort to your dog. However, in rare cases, they can be a sign of a more serious underlying condition, such as cancer.
Causes and Meaning
Black spots on a Labrador's tongue are typically harmless and caused by pigmentation, similar to a birthmark or freckle. This is a common occurrence in dogs and not specific to any breed.
The black spots on a dog's tongue are usually flat, have the same texture as the rest of the tongue, and are not raised. If the spots are raised or have a different texture, it could be a sign of something else happening and should be evaluated by a veterinarian.

Most normal spots on a dog's tongue will start out lighter and smaller, then grow and turn darker gradually. If a spot appears and develops rapidly, it's a good idea to have your vet check it out.
Black spots on a dog's tongue are often a result of domestication syndrome, which causes changes in pigmentation and coat patterns in domesticated animals. This is why many dogs have random black or brown spots on their bodies.
In some breeds, like Chow Chows and Shar-Peis, black tongue spots are a common occurrence and are even a breed standard. However, in most dogs, black spots on the tongue are simply extra pigment and not a cause for concern.
It's essential to regularly monitor your dog's mouth, including teeth, gums, and tongue, to spot any changes in their oral health before they become problems.

Labradors, being one of the most popular breeds, can indeed have black spots on their tongues. But it's not just Labradors - plenty of other breeds, big and small, can have these spots too.
Some breeds that are more prone to having black spots on their tongues include Golden Retrievers, Irish Setters, and Pugs. And it's not just limited to large breeds, as smaller breeds like Pomeranians and Bichon Frises can also have these spots.
Here's a list of some dog breeds that can have black spots on their tongues:
- Labrador Retriever
- German Shepherd
- Golden Retriever
- Pug
- Pomeranian
- Bichon Frise
- Irish Setter
- Doberman Pinscher
It's worth noting that these spots are usually just a result of extra pigment, and it doesn't necessarily mean the dog is a mix of breeds or not a purebred.
Identifying Abnormalities
If the black spots on your dog's tongue have always been there, chances are high that there's nothing to worry about. But, just like with human birthmarks, it's essential to notice any changes in the characteristics of the spots.

Raised or differently textured spots could be a sign that something else is happening and should be evaluated by your veterinarian. Most normal spots typically start out lighter and smaller, then grow and turn darker gradually.
A serious vitamin deficiency could cause a dog's tongue to turn black, or it could be a sign of an advanced tumor. However, most serious illnesses that affect a dog's tongue will also present with other symptoms, such as foul-smelling breath, difficulty eating, or excessive drooling.
If a black spot appears but everything else is fine, your pup is likely okay. However, it's always a good idea to check with your vet, just in case.

If your dog's tongue has black spots, watch for any changes in texture. If the spots become raised or the texture changes, schedule a checkup with your vet. A foul odor in your dog's mouth is also a reason to get a checkup ASAP.
Other signs of concern include spots appearing in other areas of your dog's mouth, or if your dog's tongue has never had spots before but suddenly does. In these cases, a comprehensive oral exam is a good idea.

When to Worry
If you notice a black spot on your dog's tongue, it's natural to worry. Black tongue spots are almost always harmless as long as the texture of the pigmented area is similar to that of the rest of the tongue area.
The spots can appear at any point in a dog's life, even as early as birth, or develop later in life. Some dogs are born with them, while others get them as they grow older.

However, it's essential to keep an eye on these spots, especially if they change in texture or elevation. You can inspect your dog's tongue whenever you brush their teeth to check for any changes.
Raised and hardened spots on a dog's tongue are a matter of concern, as they can be signs of melanomas and squamous cell carcinomas, two of the most common oral cancers in dogs.
Here are some signs of tumors in your dog's mouth to look out for:
- Difficulty eating
- Excessive drooling
- Foul-smelling breath
- Weight loss
Even though black spots on a dog's tongue are usually harmless, it's always better to err on the side of caution. If you notice any of these signs or if the spots change in texture or elevation, consult your vet as soon as possible.
Concerns about Changes in Skin Size or Color
Changes in skin size or color can be a cause for concern in dogs. If your dog's tongue spots change in size or color, it's worth keeping an eye on.
Watch for any changes in texture, such as raised spots or a change in texture from the rest of the tongue. A foul odor in your dog's mouth is also a red flag.
If your dog has never had spots but suddenly develops them, it's time to schedule a checkup with your vet. Any unusual changes in your dog's mouth, including new growths, spots, or odors, warrant a call to your vet.
Your dog's oral health is a good indicator of their overall health. Healthy teeth and gums go a long way toward a healthy, happy dog.
Due to Deficiency
Black Tongue Disease is a rare condition in dogs caused by a niacin or vitamin B3 deficiency. This is the canine version of human pellagra.
Dogs get niacin from the amino acid tryptophan, which is found in red meat, fish, and poultry. Turkey is a particularly good source of tryptophan.
Since dogs don't eat many nuts and seeds, and legumes are linked to taurine deficiencies, dogs who don't get sufficient meat and protein in their diets are most at risk of Black Tongue Disease.

Cancer
If you notice a black spot on your Labrador's tongue that's growing rapidly or has irregular edges, it could be a sign of oral cancer. This type of cancer can cause a range of symptoms, including bad breath, excessive drooling, and pain in the mouth area.
Some common signs of oral cancer in dogs include difficulty eating and swallowing. If you notice any of these symptoms, it's essential to take your dog to the vet right away.
Oral cancer can also cause swollen face and weight loss. If you notice any unusual changes in your dog's appearance or behavior, it's always better to err on the side of caution and consult with a veterinarian.
Here are some common symptoms of oral cancer in dogs:
- Bad breath;
- Excessive drooling;
- Pain in the mouth area;

Appearance and Embracing
Celebrate your dog's unique tongue spots as beauty marks! They're a result of hyperpigmentation, with more melanin deposited in certain areas of the tongue.
These spots can come in a range of shapes and sizes, and are often dark in color, such as dark blue or black.
The texture of these spots should be flat and the same as the surrounding tissue, with no changes in elevation.
They have no known function, and don't affect a dog's sense of taste.
What Do They Look Like?
Your dog's tongue spots can come in a range of shapes and sizes. They are most often dark in color, either dark blue or black.
The texture of these dark spots is a key indicator of their normalcy. They should always be flat.
Their texture should present the same as the surrounding tissue, which is reassuring.
Embracing Your Beauty Marks
Your dog's tongue spots are a unique trait, and they're completely normal. They're caused by hyper-pigmentation, which is a random accumulation of pigment in certain areas of the tongue.
These spots can come in a range of shapes and sizes, and they're usually dark in color, such as dark blue or black.
They don't affect your dog's sense of taste, and there's no known function for them. They're just a random trait that's inherited from their parents.
If one or both of your dog's parents have spotty tongues, it's likely their offspring will develop them too. But this isn't a guarantee, and it doesn't affect a dog's future litters if two dogs with blotchy tongues breed.
You can think of these spots as freckles and beauty marks for dogs. They're a way to appreciate your furry friend's unique characteristics.
Just remember to keep an eye on them and contact your vet if you notice any changes in texture and elevation.

Blue Eyes Origin
Blue eyes are a rare and striking feature in dogs. They're caused by a specific genetic variation that affects the production of melanin, the pigment responsible for eye color.
Some breeds, like Siberian Huskies and Alaskan Malamutes, are more prone to blue eyes due to their genetic makeup. This is likely because their ancestors were bred for their physical characteristics that helped them thrive in their harsh environments.
Blue eyes can be a sign of a dog's ancestry, with some breeds being more likely to have this trait than others. For example, the Siberian Husky's blue eyes are a result of their Arctic heritage.
The genetics behind blue eyes in dogs is still not fully understood, and more research is needed to uncover the exact mechanisms at play.
