hey what kind of shampoo did you use? Kikko had the same kind of thing you described in his ear and rump! the ear has cleared up beautifully but hus butt has gotten better but hasn't cleared up ... so iunno
currently we are using malaseb and topical cream, but its still there! our vet is baffled and we are trying new topical medicine this week....but its been there awhile now. so maybe i need to get my vet to give me a different shampoo ...
