Thanks DTA (I took the liberty of highlighting the ingredients in your post, hope you don't mind).

All of those oils are good, except perhaps soybean oil. While soybean oil is a great source of Omega-6 linoleic acid, it has unfortunately also been linked with food allergies in dogs, but the opinion on this is debated.

Since rice bran oil already has plenty of Omega-6 linoleic acid itself, plus a great amount of Vitamin E (which soybean oil does not), I don't see the point of adding soybean oil to the mix, when rice bran oil already covers what soy brings to the table, plus the added bonus of Vitamin E, which is vital for reproduction and cell regeneration.
