Is your girl spayed?
Is it her skin that turns black?
Do you happen to have a picture of your girl you can post here? If so, simply click the little tree icon, next to the You Tube icon in the tool bar and it will walk you through posting a picture. :)
I am wondering if she may have the start of alopecia x. This is something you can discuss with your vet. You can read more below:
Alopecia X
The little black sores could be pyoderma.

Take a look at the websites and discuss these possibilities with your vet. :)
I am glad that the vet is doing the skin scraping. You can read about these here:

Please let me know how you make out with little Ebony. She and you will be in my thoughts. :)
