I highly recommend Ark Naturals Royal Coat. It' fish and borage oil. It was recommended to me by Wyliesmom and I am running around recommending it to everyone.

Sugar has seasonal allergies and his skin and coat are a real challenge. This made the biggest difference, I can't even begin to tell you. Night and day. I've used Missing Link in the past and also salmon oil. Royal Coat rocks!!
