I think it is normal for some dogs to throw up their first few raw meals. Nigel did, and then, he ate what he threw up. I know it sounds gross, but it's easier for them to digest the second time around.
I just kept giving him chicken for every meal and within a day or two he was digesting everything fine.
I have a great book on raw feeding, which I definitely recommend. It simplifies everything. It is called: Raw Dog Food, Make it Easy and Fun for your Dog! by Carina Beth MacDonald. I found it to be a great resource and you don't have to keep hunting around on the internet for more information if you just get the book.
