I have heard good things about this book http://www.amazon.com/Dog-Food-Logic-Decisions-Choices/dp/1617811386/ref=sr_1_1?s=books&ie=UTF8&qid=1392962076&sr=1-1&keywords=dog+food+logic
I like to use a quality kibble as a base and add a spoonful of cooked chicken, scrambled egg or something. No free feeding. I have had good luck with Nutrisca Salmon and Chickpea, check chewy.com.
And regarding the episode you described, these things happen …I am waiting for lab work results myself for a dog that had poor appetite and some other vague symptoms X 2 days.
So far it does not appear to be related to his diet…
