dogfoodanalysis.com is also "opinion"...THEIR words...based on the opinions of the site editors, not long term research. So take that for what it's worth.
It has lots of good information on it, but please don't be mislead into using it as your only search of information. (I did that instead of listening to my gut and it almost killed one of mine!) Or just what is on the label--they are designed by the company to promote their products! Not to mention misleading.
For research, try this link as well:

It has links to numerous sites, the benefits of home cooking and examines raw feeding and it recommends publications that address nutrition in detail and long term facts. Talk to a canine nutritionist if you can. There are also links at the top of this section with details of how you can get free samples to try. Just realize that what one person tells you is best for THEIR dog may not be the case for yours.
