Many dogs that are being bitten by fleas do not have fleas that can be found on an examination. This is especially true of dogs that are allergic to fleas. Because the dogs are very very good at finding the flea and ingesting it. This is even more true in the case of cats, who are also equipped with a barbed tongue and extraordinarily flexible bodies to help in capturing the fleas. So I wouldn't rule out flea bites just because you can't find fleas.
Fleas like to live on pets if possible.
They attack humans when their favorite targets are unavailable. If you continue to have problems with the rash it would be a good idea to get your doctor to recheck you, too.
