Several dog owners are not aware of the causes of the dog’s black spots and might, therefore, fail to find the appropriate remedy to address such black spots issue.

7 Causes of Black Spots on Dog’s Skin & Belly

There are several causes of black spots on dog’s skin including:

#1 Thyroid deficiency

If you notice that your dog has black spots that are tender to touch and are changing in shape and size. This is an indication that your dog has a thyroid condition. With a thyroid condition, the dog will lose some hair. This then makes the black spots to be more visible.

Hypothyroidism happens when your dog is not secreting enough of the thyroid hormones, causing your dog’s metabolism to slow down. This condition is more common in dogs than in other types of domestic animals, but it usually responds well to appropriate medication given by a vet.

#2 Secondary Acanthosis Nigricans

The Secondary type of Acanthosis Nigricans are more common than the primary form of the condition and can affect any dog, regardless of the breed. The disease is caused by friction, which is due to hormonal imbalances, the dog’s obesity, or hypersensitivity to food. This disease results in increased black spots in the dog’s skin.

#3 Acanthosis Nigricans

Acanthosis Nigricans is an uncommon cutaneous reaction pattern characterized by axillary hyperpigmentation, lichenification, and alopecia.This condition is rare and primarily affects puppies that are less than one year old. Also, the condition usually only affects Dachshund breeds. When your dog is affected by the disease, its skin thickens, and black spots appear on its skin.

#4 Hemorrhage

Hemorrhage is a bleeding condition that is commonly known as vasculitis because of its reference to the blood vessels. When the dog is bruised, the blood capillaries below the skin get ruptured. As the blood comes out, some will be trapped below the skin.  This will cause skin discolouration and black spots above the trapped blood.

#5 The Sun

The presence of melanin protects the dog from harmful ultraviolet rays emitted by the sun.  The rays are dangerous and can cause dark spots on your dog’s belly. If your dog stays away from the harsh rays on extremely sunny days, the dark spots should go away within 1-2 weeks.

#6 Aging

When your dog is old, it develops age spots, which are dark in color.

These dark spots due to age are not harmful, and therefore, individuals are usually advised to know the ages of their dogs in order to rule this type out.

#7 Allergies

When the dog is allergic to some environmental factors, it might show some signs including the appearance of dark spots on the belly.

Black Patches or Scabs on Dog’s Skin

Black patches and scabs are different than black spots. They cover a wider area of the skin normally and are all black where spots mostly look like little black circles.

Sometimes the black patches can occur naturally. They can be seen in areas of friction such as legs, and armpits. However, when the dog is allergic to something, you are likely to notice the black patches on their skin.

Therefore, you should watch your dog careful to be able to differentiate between these two types. You could also remove anything new that may have caused allergies the see if that helps get rid of the black spots.

In some cases, you may notice that the occurrence of black spots results in the loss of the dog’s hair. This is often due to an infection and it is recommended that you monitor these changes and call your vet.

The drug that can be given to the dog if the cause of the black spots is hypothyroidism is Levothyroxine. The dosage will differ depending on the dog affected, age, and bleed.

If the cause of black spots is yeast infections, make sure you treat it as soon as possible. In this particular case, you can treat yeast infections using:

  1. Using shampoos with either 1% benzoyl peroxide, ketoconazole, sulfur, or chlorhexidine.
  2. Injections and oral medications can be applied, more especially, if the topical medications have failed.
