I would do a search bc I know there are quite a few threads on this already. Also do a search on the breeder section. I think a lot of people use Nitro bc it is all natural. Currently I use Purina Pro Plan bc the breeders where I got my Yorkies from used it. I know a lot of people are against it bc it has corn in it and dogs can have allergies to the corn, but mine have never had any problems. I guess I grew up on a farm and the dogs there were always eating raw sweet corn bc they like the milk in it an none of them ever had any problems.
Anyway you are going to want to find a food that doesn't have animal by products in it or corn (I know Pro-Plan has both). Good luck with your search.
