Diagnosing Hyperpigmentation In Dogs
Your veterinarian will base a diagnosis on particular symptoms and the physical appearance of your dog. If you have a young Dachshund, other potential causes for hyperpigmentation should be ruled out first. A thorough history is taken and a physical examination is carried out to diagnose a cause for the condition. In the case of secondary hyperpigmentation, there is almost always an underlying disease to blame. In order to narrow down potential causes, skip scrapings are taken from the affected sites and examined for other issues . Your vet may recommend additional testing depending on the findings, including diagnostic procedures like endocrine function tests, allergy tests, and skin biopsies for further examination. If there are secondary bacterial infections present, your vet will treat those before moving on to other tests.
Allergies And Hyperpigmentation In Dogs
Hyperpigmentation is most often associated with chronic itching. This is called pruritus-induced hyperpigmentation .
You and your veterinarian have to manage the allergies causing the itching and chronically inflamed skin to treat the changes in skin color.
Although the skin may never return to its former light color, treating chronic skin conditions and the causes of itching and self-trauma is important for your dogs health and comfort.
At this point, you might be saying to yourself that you havent seen your dog bothering their belly for a long time, so itching cant be the cause of the hyperpigmentation. This is because the trauma, such as chronic licking or scratching or infected skin, could have occurred months before, and you are only noticing the color change now.
Think back to that redness that occurred last summer inside your dogs legs or when the dog spent a couple of weeks licking their belly in October. Perhaps these same patterns of itching occurred over months or years. The color change from that chronic trauma may only be visible now.
Skin Cancer Treatment Options
A diagnosis of cancer for your dog is scary. Many types of skin cancer are treatable if caught early on, but it is understandable to feel worried.
Your dogs prognosis and treatment options will depend on a few factors, including the type of tumor, the location of the tumor, and the stage of the cancer.
Some skin tumors can be removed surgically to great effect. Others may require additional steps, such as radiation or chemotherapy.
Some types of cancer, for example malignant melanomas, are resistant to radiation therapy, while others, such as mast cell tumors, are more sensitive. Your veterinarian may refer you to a veterinarian oncologist when you have a cancer diagnosis. Veterinary oncologists have advanced training in cancer treatment.

What Are Symptoms Of Hyperpigmentation In Dogs
If you’ve noticed this change in color and are wondering, ‘What are these black spots on my dog’s skin?’, you’re not alone. This change appears as light-brown to-black areas. While hyperpigmentation may be the singular symptom of a skin condition, it sometimes appears on areas of the skin that feel rough or velvety to the touch. This may be due to the skin thickening in the areas where skin feels rough or velvety.
This issue is a secondary change on a dog’s skin. A number of factors can cause the skin to change pigment. If darker skin pigment accumulates on the skin, the skin will grow noticeably darker than the rest of the skin on his or her body.
You might also note other skin symptoms including itchiness, crusting, redness, scaling and hair loss. The skin may also be abnormally sweaty or moist. Conversely, it may also be dry to the touch and have dandruff.
There are two types of hyperpigmentation: primary and secondary.
Primary diseases that may cause hyperpigmentation can occur in any breed but especially in Dacshunds. This type of hyperpigmentation is typically evident by the time a dog is one year old.
A common symptom, secondary hyperpigmentation can occur in any dog breed and is triggered by friction and/or inflammation that leads to additional skin changes such as odor, hair loss, thickened skin and pain.
Treatment Of Black Bumps On Dogs
Treatment recommendations will be determined by the underlying cause of the bump. An abscess may be draining, tick removed, and skin infection treated with antibiotics. For pigmented skin masses that are determined to be skin cancer, recommendations will depend on the type of cancer. Possible treatments may include some combination of surgical removal of the pigmented bump, radiation therapy, and/or immunotherapy.

Lumps & Bumps On Your Dog’s Skin
If you’ve discovered a lump or bump on your dog’s skin, it’s likely that the worry of cancer may have crossed your mindespecially if the patch of skin is discolored too. It’s important to remember, however, that not all lumps or bumps are cancerous.
In either case, careful monitoring a veterinary intervention are the keys early detection and treatment of illness, cancerous or not, that may be causing your pup’s lumps.
There are two varieties of lumps and bumps in dogs, cancerous and non-cancerousor, skin growths. Here are some examples of both cancerous and non-cancerous lumps and bumps you may find on your dog:
Why Does My Dog Have Spots On His Skin
Just like in people, there are many causes of pigmentation in the skin, many of which are nothing to worry about, but some can reflect a serious underlying disease. Should you worry about black patches on your dogâs skin? Many dogs will have naturally pigmented skin under their hair in certain areas and so if this has always been the case then it is likely nothing to worry about. New areas of pigmentations are best examined by a veterinarian and investigated in case something of concern is found.
Darker patches can be referred to as hyperpigmentation which is when your petâs skin becomes darker in certain areas. Lichenification â the thickening of skin is also prevalent in dogs. These patches can appear anywhere on the body of a canine such as the back, tail, legs and so on. Whilst the skin changes themselves pose no risk, it is best to investigate the underlying cause of the irritation, which has often resulted in itching and scratching and therefore a reduction in your dogâs happiness and quality of life.

Acanthosis Nigricans In Dachshunds
The Dachshund uniquely suffers from a hyperpigmentation condition called acanthosis nigricans. Although the exact cause is poorly understood, it is postulated that the skin darkens as a consequence to chronic inflammation.
Diagnosis is by signs, breed and elimination of other causes. Topical corticosteroid cream is sometimes used to relieve the inflammation.
Why Is The Skin On My Dog’s Belly Turning Dark
Many causes of pigment changes are of no medical consequence but some are good clues to the presence of other conditions. Although most dog parents believe that the skin darkening occurred suddenly, hyperpigmentation develops over time and is usually due to continual skin trauma. It is not uncommon for the trauma to have been present months before the darkening develops.
It should also be mentioned that even if the underlying cause is determined and corresponding treatment is completed, the skin may never return to its normal light color. Nevertheless, treating the underlying cause is of imperative importance for the dogs health and comfort.
The term hyperpigmentation indicates skin darkening or increased concentration of pigment on a certain skin area. It goes without saying that hyperpigmentation is more dramatic and intense in dogs with lighter skin and fur.
Breeds most susceptible to hyperpigmentation include:

What Are Black Spots on Dogs Skin?
Black spots usually appear on the abdomen, tail, or the back of your dog, black spots on the fur and skin of your pooch are usually an indication of hyper-pigmentation. Hyper-pigmentation results from an increase in natural pigments called melanin.Maltese have higher tendency to show signs of hyper-pigmentation than others because of their characteristic white coats. Hairless dogs also have a higher tendency because of their hairlessness. Hyper-pigmentation commonly affects the skin and fur but it can as well occur on the nails of your canine.
The black spots are in most cases harmless, especially if they are not accompanied by signs of irritation and only affect the fur with no changes to the underlying skin.
Genetic Disorders And Hyperpigmentation
- Dachshunds: Prone to a rare disease called acanthosis nigricans that causes hyperpigmentation followed by alopecia and lichenification.
- Huskies and related breeds: Prone to alopecia X, a syndrome that causes hair loss and hyperpigmentation.
- Yorkies, Silkies and crosses: Prone to melanoderma, a skin anomaly that usually causes hair loss and hyperpigmentation of the ears as well as color dilution alopecia, causing fur thinning and darkening of the skin on the body.

What Are Dark Spots On Dogs Skin
The condition is called hyperpigmentation. Dogs can have either one or several dark spots. Some are harmless, while others can indicate more serious problems. If your dogs black spots are growing on the body, they may be a sign of skin cancer. This condition affects melanocytes, which make up the skin. A doctor should perform a skin biopsy to determine the underlying cause. While the cause of melanoma is unclear, it is often caused by a dogs diet.
Some dogs may have black spots on their skin due to a yeast infection. These spots appear dirty and are easily mistaken for dirt. They first appear around the genitals. If you notice them on your dog, contact a veterinarian immediately. Symptoms of yeast infection may include scolding, excessive scratching, increased bowel movement, diarrhea, and fever. The itchiness may be caused by a food allergy. In some cases, these spots are harmless, but if you suspect them of causing serious health problems, consult a veterinarian.
What Is Hyperpigmentation In Dogs
Hyperpigmentation means a darkening of the skin, where more pigment is visible. This is obviously more dramatic in dogs with light skin and fur.
Most cases of skin darkening in a dog are secondary to other skin conditions or metabolic problems such as allergy, infection or endocrine disorders.
Skin discoloration doesnt happen overnight there has to be some degree of continual trauma or exposure for hyperpigmentation on a dogs stomach or anywhere else to result.

Fleas Ticks And Other Parasites
Many parasites, such as fleas, ticks, and lice can sometimes appear as black spots on your dogs skin. Fleas may also leave behind flea dirt. This shows up as little black flecks on the skin or at the base of the hair follicle. Ticks will bury their heads under the skin, leaving their body to stick out as a raised spot on the surface. Other parasites, such as some types of biting lice, may also appear dark brown or black against the skin.
Your dog may itch or scratch at areas these parasites bite. In some cases, an allergic reaction, called flea allergy dermatitis, may also cause hair loss and red inflammation at the affected area. Diagnosis can usually be done at home if you can identify the parasite embedded in the skin. You can also gently flick any black flecks onto a paper towel that is then moistened. If the flecks turn red or bleed, this is a sign of flea dirt and a flea infestation.
Treatment involves the removal of any parasites manually. Flea treatments such as oral or topical medications, sprays, shampoos, and collars can also help. Treating the environment by washing bedding, baseboards, and removing brush or heavily wooded portions of the yard can prevent fleas and ticks. Since fleas and ticks can transmit many severe diseases such as tapeworms, intestinal parasites, Lyme disease, and more, its important to both prevent and treat any infestations immediately.
How To Treat Black Spots Near A Dogs Privates
First, we always recommend that you see your veterinarian to determine the exact cause. For cases of primary hyperpigmentation, the change is often only cosmetic and wont require any treatment.
For secondary hyperpigmentation, yeast infections, fleas, or melanomas, you have to treat the underlying condition before the skin will lighten up. Fleas can be treated with a topical, oral or spray-on flea medication. Other pets, as well as your house, will need to be treated as well.
Yeast infections will require anti-fungal medications that can be taken orally or applied topically. Antibiotics may also be needed to prevent or treat secondary bacterial infections as well. Some yeast infections may require several weeks of treatment.
Melanomas will need surgical removal, depending on where they are located on your dog. Chemotherapy or radiation is often recommended as a follow-up.
Whatever the underlying cause of the black spots near your dogs privates may be, its going to take some time for that skin to get back to normal. Even once the inciting cause is cleared, it will still take a while for that pigmented skin to turn over into lighter colored skin.

General Signs To Watch Out For
In many cases, spots on the skin can be normal and can change some over time. However, there are some general signs to watch out for. Rapid changes can indicate that something more serious is ongoing and should be checked out by your vet. Signs of an issue include the spot becoming raised when it wasnt previous, or is suddenly changing in size. Irritation such as itching, redness, or oozing debris are also signs that something is wrong.
If the spot appears to be irregular in shape, or suddenly appears, this can also be a cause for concern. Its best to keep an eye on any spots that do appear so you can note any changes over time. Track the overall size, how quickly it changes, and any other symptoms in addition. This can help your vet determine the best course of action.
Black Spots On Dog Skin: Common Causes And What To Do
Dogs are such an important part of our lives and our families. It can be scary when a pet parent finds a new lump, bump, or black spot on their dogs skin. One condition that I commonly see in my veterinary practice is discolored or black areas on the skin. This often happens on a dogs belly or near their genitals but could also happen anywhere on your dogs skin.
Most instances of dark or black colored spots on the skin of dogs are hyperpigmentation. Hyperpigmentation occurs when there is an increase in dark pigmentation of the skin.
The pigment of skin cells is what gives the skin its color. The substance in these cells that make this color is called melanin. Specialized cells in the skin produce melanin. If these cells become damaged, it may affect melanin production.
Hyperpigmentation is the medical term used to describe an increase of the pigmentation on a dogs skin when the amount of color is more than what is normal for that dog often describing black spots on a dogs skin.
If your dog has hyperpigmentation or black spots, you may notice other changes to the skin in this area as well. Though hyperpigmentation can be seen as the only change, often the affected skin will change texture.
The skin may become rough, scaly, red around the area, itchy, or crusty. Many of these changes are caused by the affected skin thickening.
