Billinghurst I think does a superb job explaining how no commercial dogfood can do what the raw diet does; the raw diet is not just food/nutrients, its how its fed... in that its balanced NOT in one meal, but over time. Commercial foods by nature are balanced within each meal, but that is a bad thing - eg some ingredients cancel out others. Also, commercial stuff has to be cooked/heated, neutralizing or changing its components.
Thanks. I'll google Billinghurst. I presume he has a book.
