Complete natural raw food is one that contains everything a dog needs, balanced and made from fresh ingredients that are pure and natural, fresh and unheated, without the extremely valuable meat juices being removed as water can never fully replace meat juices.
Natural raw food contains no additives, the basis is fresh meat and offal in the right proportions, always supplemented with vegetables and/or unlocked grains, seeds that would be contained in the pre-digested stomach contents of the prey for optimum nutritional value.
Of course, vitamins, minerals and trace elements have to be added in the right proportions, but supplements are not the same as additives.
