Very good find, Tobi! My instinct always told me that dried food is not "natural", but this article puts "meat on the bone", if you will pardon the pun! Dogs, unlike humans, need meat in order to survive and it makes sense that they should be given a natural product.
I am sure that the article will enrage the dried food manufacturers, which are very powerful and have immense publicity budgets. But I for one trust the article you found.
Many caretakers of dogs give their dogs dried food, because they blindly trust all the hype and publicity. The article you cite may help to balance the score.
