Cedar (5 year olds) has battled wtih skin allergies his whole life. For the past two years he has been really well under control but since January of this year he has been having a flare up of a rash in his groin. I took him to the vet and they prescribed Keflex thinking it is a staff skin infection. We are only on the second day of the antibiotics so it is too early to tell if they are helping (which it looks almost worse now). I was wondering if anyone has had experience with a yeast/fungal infection that caused a rash? I just want to have other ideas if we have to go back to the vet after the 8 more days of antibiotics are up. Thank you.
