I've been feeding our dog Innova. The stuff is expensive but you're paying for what you get not some national advertising campaign. The better dog food not only means the dog has fewer stinky farts and shits but the dog will also eat less of it.
Pure meat diets aren't necessarily the best diet for a dog, as wild dogs would've had eaten herbivores and the partially digested grasses in their stomachs so some
vegetable content is actually good for your dog. However you shouldn't be feeding him/her a corn based food or ANY that contain Cellulose (i.e. wood pulp/saw dust).
