Hi. Thanks for the photos. There are a few common things that can cause the dark coloring, hair loss, and even itching. The most common can be allergies. Others would be deep infection, parasitic, low thyroid, and hormonal imbalances. With the photos here and the severity, I am highly suspicious of severe allergies or low thyroid level. I would make an appointment with your veterinarian when you are able and they will do a full exam. They will do some skin testing, bloodwork that will include thyroid levels, and whatever medication may be needed depending on the probable cause after an exam. Good luck
