Re: OMGness, what is this????
OK, after googling that does not look like a bullseye, as a bullseye rash looks red in center, then white, then red again - so hope you are not freaking out about lymes disease or ringworm, which is what bullseye rash is from I saw.
On the other hand, I would bring him in tomorrow as it could be some kind of bite, but probably good to get it seen, probably nothing....
