Black Spots on Dogs Skin [ Cause & Prevents 2023 ]

Primary or Secondary hyperpigmentation in dogs:

Hyperpigmentation is generally a secondary condition and results as a secondary effect. It often results from skin trauma. The most common cause of skin trauma is skin inflammation, such as redness or scratching.

The skin repair cycle is initiated when such trauma occurs. Increased melanin pigment is a protective factor for superficial skin layers as part of skin repair. Skin appears darker to see when this protective melanin pigment accumulates in the layers.

The most common causes of darker skin problems in dogs include allergies, scratching, skin infections due to bacteria, skin inflammation due to parasites, and self-trauma caused by activities such as scratching, rubbing, licking, and biting at the skin. All of these can cause hyperpigmentation.

Darker skin sometimes occurs after a skin problm has already occurred, and the skin is healing from trauma. Dogs can also develop darker skin due to breed-specific variations, hormonal disorders such as hypothyroidism and Cushing’s disease, medications, physiological changes, etc.

The presence of other skin changes, such as hair loss or skin redness, is typically more helpful in determining the cause of the skin changes and correcting them, including hyperpigmentation.

When a dog has skin-related changes, it almost always has an underlying cause, so it is crucial to diagnose and treat the underlying problem. Veterinary dermatologists or family veterinarians are best suited to assess such underlying causes to determine how hyperpigmentation developed and the best treatment for the affected area.

Infection with fleas

A yeast infection can also cause dark spots on your pup’s skin by overgrowing Malassezia pachydermatis. The dark spots are usually flushed or flat and appear around the groin area if he has a yeast infection.

Itching, oily skin, hair loss, black spots, foul odour on the skin, licking, and scratching are also symptoms. Your veterinarian can use an impression smear to determine whether your dog has a yeast infection.
