After thinking about it last night, ringworm does look like with the raised circle around it but I was thinking maybe when the groomer was drying her she had her standing up against her and might have got the dryer on her skin. It is very strange, hope she is doing good, if she is acting normal today and it looks as if its healing I wouldn't worry about, but I would certainly watch and check her next time she goes to the groomers just in case..
