My 14 YO girl has a case of seborrhea. Her skin is red, scaly, and flaky, although she does not seem to be exceptionally itchy. There is one patch where the fur is very, very thin. I have to bathe her every other day with a medicated shampoo, and ensure that it stays on her skin for 10 minutes. She's never had skin problems before this, and the vet is testing her for Cushings, among other things.

Anyone else have any advice on how to help her? She gets a salmon oil supplement 2x/day already.
