are you sure its just dry skin and not some type of fungal infection? i would be concerned too with the beastie licking medicine off. how often do you bath him/her? if its on a regular basis, then dont. I know a lot of dog people add fish oil to their pets diet and that helps soothe(or something like that..). I give mine fish oil pretty often and we havnt had any dry skin problems. Do you feed her or him ferretone?
