A book which I found really useful and far less confusing than the BARF books is "Real Food for Cats and Dogs - A practical guide to feeding your pet a natural balanced diet" by Dr Clair Middle. The lady is a vet of 25 years experience and writes in a clear, easy to understand manner. Simple to put her ideas into practice. It is published by Fremantle Press in 2008.
It contains many tips about natural feeding which do not appear in other books (eg feeding zucchini and eggplant should be avoided for itchy dogs).
Try your online local library catalogue first. (Brisbane City Council have a copy, maybe others do too).
