I have a five year old puppy mill rescue "Nellee" whom I spoil and love. Shortly after I got her, her coat became greasy. Like so many other posts, she is not greasy for a day or two and then by day 5 or 6 she is greasy and smelly. I have tried many different shampoos and she has been to the vet and got a clean bill of health. The vet recommended changing her food which you have to change slowly. So far there has been no change for her. I see a lot of post regarding this issue and no way of fixing it.
