Dog Has Black Skin Spots and is Losing Hair – Top 3 Reasons Why

Dog owners should do regular checks of the dog’s skin as the quality of the dog’s skin and fur will provide plenty of clues on the overall health of your pooch. One concerning condition that some dog owners may notice is the development of hair loss and black skin spots. Here are the most common reasons why they occur.

1. Development of Black Skin Disease

Also known as alopecia X, some dog breeds are susceptible to skin disorders like black skin disease. Breeds like Pomeranians and chow chows, for example, may start to display symptoms once they reach two to three years of age. Dogs that are diagnosed with these conditions will show symptoms like hair loss and the hyper-pigmentation of the skin.

2. Dogs Affected by Lichenification

Some dogs may start to develop black spots on their skin due to a condition called lichenification. This basically refers to skin that becomes thick and leathery. It can happen to dogs affected by chronic inflammation and trauma.

3. Effects of Severe Allergies

The development of black skin spots may also be a result of an allergic reaction. Hyperpigmentation, the term used to describe the darkening of the skin, can happen from chronic itching and allergies are a prime culprit of this condition.
