Um, yes, a dog is an omnivore but one with desire/need to eat around 60/80% MEAT with the rest as veg, offal, whathaveyou.. however no they are NOT designed to eat a diet made primarily of cereals, which is what brainless is getting at there.
Food labelled with meat (and real meat, not 'meat meal' or 'animal derivatives')as the greatest ingredient is better than food where the greatest ingredients are cereals such as rice, wheat, corn, oats etc etc.
However its hard to tell, because some food produces will label a food as being 20% chicken, 10% rice, 10% corn, 10% oats, 15% vegetable matter, etc etc .. whilst the largest SINGLE ingredient in that food is indeed chicken, adding up the rest, there is 45% of the food made up of cereals and veg fillers.
