Dogs Pink Belly Turning Black Over Time? Hyperpigmentation 101 Facts

Is Your Dog’s Belly Turing Dark From Regular Pink With Time? One of the most common reasons for your dog’s belly turning black over time is Hyperpigmentation. It is basically a darkening of the skin. Moreover, this is not an overnight process. There is a particular level of continuous exposure or trauma for your canine’s belly area to turn black. 

Hyperpigmentation in Dogs: Dog’s Tummy Turned Black

Hyperpigmentation is the increase of dark pigmentation of the skin. If you find dark patches on your canine’s belly, you may think of hyperpigmentation as a potential cause. There are many conditions that result from this disease. 

To be honest, hyperpigmentation is a secondary condition. Therefore, it is a secondary effect. Moreover, it usually happens when there is a certain trauma to the skin. Any skin inflammation like redness or scratching is the most common cause. 

When this happens, the skin repair cycle is turned on. This cycle involves increased protective melanin pigment. This is a protective effect on the skin layers. When the protective pigment enters the skin, the skin is darker to see. 

Reasons for skin allergies in canines include skin infection due to bacteria, scratching, skin inflammation, self-trauma, etc. 

In a few cases, hyperpigmentation of the skin can occur after a previous skin problem and the skin is in the healing process.

Types of Hyperpigmentation in Dogs

Primary hyperpigmentation

Primary hyperpigmentation is not that serious because it is mostly cosmetic. It affects the skin appearance of your canine. However, it will not affect it beyond that.

The only thing you must ensure is that your dog does not experience any discomfort because of it and that you are able to touch the patches easily. 

These patches will not go away soon. Moreover, any treatment would not do much to the patches.

Your canine will not experience any discomfort if they have hyperpigmentation. However, these patches can be permanent sometimes. 

Secondary hyperpigmentation

Secondary hyperpigmentation is something serious. You need to be extra cautious if your pet has secondary hyperpigmentation. This is because it is a symptom rather than a condition. 

This symptom is a sign of your pet getting ill in some way or the other. Of course, you need to find the cause and treat it with appropriate treatment. This means that the dark patches can disappear on their own. 

Miscellaneous Causes of Hyperpigmentation in Dogs

  • There are different reasons for a canine to have hyperpigmentation. 
  • Some of the causes include follicular dystrophy or acanthosis nigricans. 
  • Some canines may have hyperpigmentation because of hormonal problems like hypothyroidism or growth hormone-responsive alopecia. 
  • Additionally, folliculitis, castration-responsive dermatosis, Cushing’s disease, and injection-site alopecia can also contribute.

Diagnosing Hyperpigmentation in Dogs

Hyperpigmentation in dogs can be diagnosed through appearance signs on your dog. Your vet will try to mitigate other causes of the sign. 

Your vet may ask you some basic questions like

  • Is the itchiness in a particular season?
  • Why is your dog’s belly turning black or red?
  • Why is the area itchy? How is it itchy?
  • What is your dog’s allergy history?
  • Why does the darkened skin smell?

Once you have answered these questions, your vet will try to diagnose other possibilities like cytology, skin scraping, biopsy, etc. thus will help the vet to identify the root cause and treat it accordingly. 

Treating Primary Hyperpigmentation

There is no cure for primary hyperpigmentation. However, if you detect it early, you can manage it with special shampoos and steroid ointments. In some canines, the condition is just cosmetic and does not require treatment. 

Treating Secondary Hyperpigmentation

In secondary hyperpigmentation, your canine’s skin will be normal again after the treatment.

It is also important to treat any bacterial infection or yeast along with hyperpigmentation. 

Your vet may prescribe antibiotics or antifungal medicines to treat bacterial or yeast infections.

He may also recommend medicated shampoos that you need to apply 2-3 times a week. 

Recovery of Hyperpigmentation in Dogs

The recovery procedure is slow and may take a few weeks or months to take your canine’s skin back to normal.

Your vet will see whether any follow-up is required. These follow-ups are focused on continuously treating the area of concern and cause of hyperpigmentation for your canine. 

When Hyperpigmentation is Considered Normal?

Your canine’s skin turning black over time can be normal when your pooch ages.

Mild darkening due to exposure to the sun is very common. This is particularly common in puppies with light coats. 

Any changes in gaur cycle arrest can also cause skin darkening. This especially occurs in plush-coated canine breeds.

Certain changes in hormones due to certain muscle-building drugs can also cause hyperpigmentation. 

Is hyperpigmentation in dogs dangerous?

If you do not provide proper treatment for hyperpigmentation, it can spread to other parts of your canine’s body as well. Moreover, your pooch may experience discomfort and itchiness. Additionally, the dog could even experience fluid discharge, hair loss, and infections. 

Allergies and Hyperpigmentation in Dogs

Chronic itching is one of the reasons for your canine’s skin turning black. This is called pruritus-induced hyperpigmentation. You will have to handle the allergy triggering the chronic inflammation to reverse the changes. 

Although your canine’s skin may not return to its original colour, treating this skin condition is severe for your canine’s overall comfort and health. 

Genetic Disorders and Hyperpigmentation

Some canine breeds are majorly prone to develop black patches around the stomach.

For instance, breeds like huskies can easily get alopecia. This contributes to hyperpigmentation and hair loss.
