I've been meaning to post this for a while but just remembered:
Both of Dr. Lonsdale's booka are available in their entirety online:
Raw Meaty Bones:

Work Wonders
http://www.rawmeatybones.com/book-ww.html
I very much admire Dr. Lonsdale for his guts to blow the whistle on the pet food industry, and continuing to do so, despite it not exactly making his life easier. And I'm endlessly grateful for the educational work he is doing.
It's a very generous thing to make these books available not just in the form of a few excerpts, so please check them out and if you like them, show your support and buy a copy.
