Nicki remember you were asking about that book that offered an analysis of various diets? I just realised Monica Segal who is extremely well qualified in nutrition and animal science, and well respected has written such a book:
And it offers various diet menus etc. I bet this might be just what you are looking for. And she has cavaliers -- you may remember she joined the Chiari list for a while and gave some advice on feeding SM dogs.
I am going to order this myself. I have several of the raw meaty bones diet books, but I have moved away from RMBs as a main diet to more of a dietary supplement and am very interested in a considered look at nutritional needs and cooked diets and supplementing commercial diets.
