I would recommend an examination by your vet. Darkened areas of skin can result from inflammation of the skin and this could be due to a fungus such as ringworm, a bacterial infection, or we can see skin tumors/growths in dogs as well. Your vet can examine the skin/fur and may recommend a ringworm culture, a skin cytology test to look for bacteria or yeast, or other testing depending on the appearance.
