A great place to go for information on what to feed your dog is the Whole Dog Journal. http://www.whole-dog-journal.com/
Every year they do a lovely article on food. They give you great tips on how to read labels and what things to watch out for. You can then make an informed decision on what you feel comfortable feeding your dogs. At the end of the article they have a listing of all the brands and varieties of dog food that they deem "acceptable." There's quite a variety from the economical choice of Chicken Soup for the Dog Lover's Soul, to some of the high end foods like Evo. It is WELL worth the read and a great tool to have when making a trip to the pet store. I usually print out the list for my puppy buyers and ask them to at least please feed something that is on the list, unless they'd love to go raw.
You can purchase the article from their website, it is $10. Better yet, get a subscription to the magazine! It's really nicely done with a good holistic attitude and they have nice positive training and behavioral articles.
Looks like they JUST came out with 2009's dry food review, there's a link to the article on the home page where you can go, and then after a quick intro blurb you can click on "purchase selection" to then download the whole thing.
