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.

Skin Growths And Tumors

Skin growths and tumors can create a raised, black, spotted appearance on the skin. Often, these issues wont be flush with the regular skin pigmentation and can have an irregular shape to them. They may also rapidly change in size and shape, or cause irritation and redness around them. Skin growths, such as skin tags or cysts can be benign, but may still be unsightly or need to be removed if they appear in problem areas such as on the joints. Tumors can be more serious, though some skin tumors, such as lipomas, are usually benign.

Changes to the skin from growths should always be checked out by your vet. It is impossible to determine if a growth is benign or cancerous without having the growth evaluated. This generally involves either taking a biopsy of the area , an aspirate of the cells within the growth with a needle . These are then looked at under a microscope or sent off to a lab to determine the cell type present.

Treatment varies depending on what is causing the growth. For benign growths, they may just be left alone and monitored, especially if they arent causing any other issues. For cancerous growths, removal is the best option. Your vet will likely remove both the growth itself, and some surrounding skin and tissue to make sure all sections are removed.

Treatment Of Hyperpigmentation In Dogs

If hyperpigmentation is primary there is no cure. However, when caught early enough the signs can be managed with shampoos and steroid ointments. Other medications can be used as signs increase or get worse. In the event that there are any other infections, those will be treated as well.

When the diagnosis is secondary hyperpigmentation your dogs skin will return to normal once the underlying issue is taken care of. It will be important to also treat any bacterial or yeast infections that he has as well as the hyperpigmentation.

Antibiotics and antifungal medications can be used to treat yeast infections and bacterial infections of your dogs skin. Medicated shampoos may also be utilized to help your dogs skin. Treatment is applied 2-3 times a week and the progress may be slow. Relapse of hyperpigmentation will only be high if the underlying cause of the symptom is not taken care of correctly.

How Long Does It Generally Take To See The Effects Of Treatments For Black Skin Disease In Dogs

Dogs Get Skin Cancer Too

If your pup is suffering from canine black skin disease, you may be wondering how long it will take for the treatments to improve their condition. Unfortunately, the answer is not cut and dry. Depending on the type of black skin disease present, the severity of symptoms, and other underlying medical conditions affecting your dogs health can all influence how long it takes for treatment to take effect.

The most common type of canine black skin disease is demodicosis or demodectic mange which occurs because of an imbalance in your pups immune system caused by tiny mites growing out of proportion on the skin’s surface. This can often cause bald spots and lesions accompanied by severe itching as well as increased chance of secondary bacterial infections due to breaks in their skin barrier. Treatments are available that target both mite populations directly and support a healthier immune system such as regular baths with medicated shampoos, dips with Ivermectin or Amitraz, antibiotics if necessary to treat secondary bacterial infections, dietary changes if needed to support a healthy gut microbiome like adding probiotics or probiotic supplements into their diet as well tracking any food sensitivities that could be causing inflammation throughout their body leading to a weakened immune system response.

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.

Hyperpigmentation In Dogs: Primary Or Secondary

Generally speaking, hyperpigmentation is a secondary condition, thus it is a secondary effect. It happens most often when there is trauma to the skin for any reason. Skin inflammation such a redness of skin or scratching the skin are common causes of skin trauma.

When such skin trauma occurs, the skin repair cycle is activated. Part of skin repair involves increased melanin pigment as a protective effect for superficial skin layers. When this protective melanin pigment accumulates in the skin layers, skin is visibly darker to see. Causes such as skin allergy in dogs, scratching, skin infection due to bacteria, skin inflammation due to skin parasites, and self-trauma by dogs with activities such as scratching, rubbing, licking, and biting at their own skin are commonly seen in dogs with skin problems. These all can lead to hyperpigmentation.

Sometimes darker skin, i.e. hyperpigmentation of the skin, may occur after a skin problem has already occurred and the skin is healing from previous trauma to itself.

Other causes of hyper pigmented skin in dogs include breed-specific variations, hormonal disorders such as hypothyroidism or Cushings disease, effects of medications, physiological changes, etc. When other skin lesions such as hair loss or skin redness are evident, these signs are typically more helpful in finding the cause of the skin changes and correcting the signs including hyperpigmentation.

Can These Spots Be Cancerous

Unfortunately, these spots can be an indicator of melanoma cancer, but this is not always the case. These spots might be malignant or benign, but it will take further testing to provide you with exact answers. Cancerous melanomas are more likely to be found in hairless dogs, and these spots might grow quickly. If there is any rapid change in a black spot, you should reach out to your veterinarian immediately.

Skin cancer is the most common type of canine cancer. A range of culprits could be to blame, including UV radiation, chemicals, and more.

Benign melanoma should still be monitored for any change, but they usually just appear underneath the hair and are a few shades darker than the normal skin color. They might grow and change but at a much slower pace. They are viewed as not much more than a freckle!

The only way to know if a spot is benign or malignant is to book an appointment with your vet as soon as possible.

Obesity / Hormonal Imbalnce

Please Help!! Very worried about sudden skin issue!

If a dog is fat, he will have excess skin flaps that occur due to his obesity. When rubbed together, the skin flaps will create friction, which will lead to skin inflammation. If left untreated for long periods of time, frequent inflammations will trigger the release of melanin, which leads to the formation of dark patches on your dogs skin.

In addition to obesity, another cause of dark spots might be due to hormonal imbalance. Hormonal imbalance is when there are either too few hormones produced or too much. Either way, the external signs of hormonal imbalance first appear on the skin, and here are some of the following reactions:

  • Skin Infections & Recurring Hair Loss
  • Significant Weight Change
  • Increased Sessions of Eating / Drinking
  • Signs of Weakness / Lethargy
  • Recurring Heavy Breathing

If you suspect that your dog is suffering from hormonal imbalance, you can either wait to see if your dog can restore the hormonal balance on his own or go to a vet to receive a diagnosis of your dogs condition. I would recommend the latter option, but the final choice is strictly up to you!

After covering all the causes behind black spots on a dogs skin, now is the time to cover the solutions to this skin condition. As always, figure out the cause, and then, look for products that might solve that particular problem.
