Vitamins and minerals in dog food
Virtually all dog foods add vitamin and mineral supplements to ensure that everything your dog needs is present. They come together in a multi-vitamin/mineral complex in the form of a white powder that is nutritionally exactly the same as the multi vitamins and mineral supplements you would find in your local pharmacy. Some of the supplements' constituents are, however, artificially produced which has criticism from some natural feeding advocates.
