Your dog does not have Black Skin Disease, it has Eczema. While this can look different on different dogs, scaly skin is one symptom of eczema. This is also often accompanied by a yeast infection.
Eczema is also known as Atopic Dermatitis, and is an immune disorder. Causes include chemicals and other pollutants. It can be treated with antibiotics, shampoo, and cortisone. You will also need to improve your dog's diet and make sure it is getting enough potassium. With the right treatment, you can treat eczema very quickly. Ask your local vet to suggest a cortisone cream based on the intensity of the disease.
