any vet/animal workers nearby? dog question

[lynetteSC]

Hi guys! Just noticed round spot on my dogs legs. It is kinda at the top part of her leg...about the size of a nickel. Looks like a scrape, but can't figure out how/where she would have gotten a scrape in that part of her leg. It doesn't have any blister. No bleeding or swelling. My first thought was brown recluse spider bite, but doesn't look like any pictures I have seen online. (Unless it just happened this evening). Doesn't seem to bother her except when I put alcohol on the site. Our vet is closed for the night. Just curious if anyone has any ideas! Thanks!!!!

My dog gets bare spots on her where she's been laying or sitting. Could it be something like that?
