Brewers rice is an extremely low grade of grain and what you might not realize is the whole plant is used, yes stalk, stems and so on.
Corn and wheat are in the same boat, they use the whole plant and with corn they include the cob. They use feed grade not what you get in the grocery store. I could go on and on about this product but it would be easier to talk about whats good in this dog food. Sodium selenite has been gone over on many different sites and most manufactures have dropped it. Sorry I would not feed this to a pig. Check this site out it will give you more info than I have time to give out.

I believe the biggest issue with kibble is trust and Eukanuba is made by p&g which is a company I could never trust.
I gotta go and sorry about the typing as I can not reread my post. Good luck with your dogs.
Kirkland, Plusar and Heathwise are all cheaper dog foods that are an much better option.
