Query: Disappointing

I have several dogs, have been feeding them a raw meat diet for 2 years and have read many books on the subject. I wanted to make sure that I am including the correct nutrients so bought this book for the recipes. What a shame! All of the recipes in this book were variations of the same recipe: Cooked meat, bonemeal tablet and 1 multivitamin. Don't waste your time or money on this book. This is the first time I've ever sent a book back for a refund.
