Sunburn?

A few days ago, I noticed that Abby had some light pink spots on her nose.

 I've been watching them for a couple of days now.

They don't seem to bother her (Are you kidding? Nothing gets between Abby and her peppermints!) but I have talked to Tim about it.

I think it's sunburn, and am continuing to monitor it. If it starts spreading or or if Abby starts acting as though it bothers her, then I'll call the vet.
