My dog has a scab on her back that fell off today, and there is now a spot with no hair. What is wrong?

She had a small black bumpy scab on her back and I noticed it today while I was brushing her hair. It fell off and she has no hair in that little spot. It is not noticeable unless you look closely, but I was just wondering if you knew what it was. She doesn't itch it or lick it either.

that happens sometimes.
i personally have a scar that doesnt have any hair growing in it,
its on my eye brow.
it just depends on how deep the scratch was.
everything should be fine.
