Switching foods is not an easy decision. You're wise to ask for opinions. I'd also recommend that you do some reading to add to your research.
I no longer have a chi, I lost her last fall. My family has always had chis, I'm now the "rebel". It's because I love the little guys that I still watch this board when I can. If you go to a previous post I explained about when I switched my girl to Avoderm many years ago - that post is here.
In my opinion you are correct to look for a more "natural" food. To me this means less fillers and, well, no stuff that doesn't need to be there as it isn't helpfull and can even be a hinderance.
Whole Dog Journal does a good job about educating about kibbles.
A book that explains more about home cooked diets is Dr. Pitcairn's Complete Guide to Natural Health for Dogs & Cats.
If you want to look into raw feeding the books by Ian Billinghurst give some good information.
I feel that no one person, especially online without knowing you and your dog, can give you the "right" answer. These resources were very helpful to me when 2+ years ago we went through a rough time trying to find something that would work for one of our 4 legged family members who is not tollerant of carbs. It now amazes me that at one time I didn't even look at the ingredients on dog food.
Good luck and keep us posted!!
