My dog has recently developed some kind of skin problem, I only noticed it the past week and have no clue what it is.

From what i gather... It does not hurt, only to touch it or disturb it. You can feel a small bump (about a loonie). When you part the hair, it looks to be scabby/black against the skin. It's position is the exact middle of her back.

When you touch around the area it seems to hurt a bit but not as much as if this one area is disturbed.

Can anyone please help me with this problem...

Thanks,
Brad
