Whats the best adult dog food?

Nutro has the highest levels of essential fatty acids and is the only company that I know of that guarantees healthy skin and coat. In their foods you will find no ground yellow corn, which is a filler and a big allergen among pups. No by-products, which can include heads, feet and intestines. No artificial colors or flavors. It is a human grade food and is all natural. And all of their foods are 100% guaranteed!
