I feed Taste of the Wild Pacific Stream... it's got gobs of salmon in it, no chicken or poultry at all. Smells extremely non-fishy too, at least in my opinion. I think it's because it's mostly salmon and smoked salmon.
Instinct has a few grain and chicken free formulas, but to quote another thread... "take a shovel with you on walks if you try Instinct"... it seems pretty common for dogs fed Instinct to have frequent, large, messy poops. It's disgusting.
I really like the TOTW, and so do the dogs!
