I have used ark naturals royal coat express, its fish oil with added vitamins. It worked well for both my cats and dogs, but I have recently switched to coconut oil, in hopes that it will help with my dogs eye staining. Both are very good, will help with dry coat, dry and itchy skin, both will also help with coat shine. The coconut oil has MANY other uses though too, Ive been using for myself and my kids and so far we are loving the results.. Here is a link explaining what it is and what it does.
