Dr. Strombeck (Donald R. Strombeck, DVM, PhD, is Professor Emeritus, University of California, Davis, School of Veterinary Medicine.) has an extensive selection of recipes (cooked, not raw) at his site, to include special needs. You might wish to take a look there. I recently stumbled upon it. He uses multi-vitamin (and provides calibration for dog’s weight) to ensure completeness and bone-meal to balance Ca:P.
He has a book on Amazon, but it is out of print, expensive and all of the recipes are on his website. Lots of good information there for free.
