I always read the ingredients first. I fed Pro Plan to my dog for her first two years, then switched, then switched again. She hates it. Foods I've fed my dog, Purina One (bad), Brandon Farms before they jacked the price to $27/5lb bag (Yes, it costs that much), several Wolf brands (natural, good, $25/10lb), Chef Micheal's (okay, $11/8lb), several Instinct (natural, good, $25/10lb), and several others. I always buy small bags for variety or the little bratty princess just won't touch her food.
