What Should We Feed Our Dogs?

In my search to find the best dog food available I have narrowed our options down to three broad groups. I've listed them here with a brief explanation and expand on all three options further down this page, including reviews and direct comparisons.
1. Commercial Dog Food: This includes the packaged foods you find at your local supermarket, pet store or veterinarian. Commercial dog food is available in dry, semi dry and wet (canned). All the big names that we know so well are represented in this group, such as Diamond dog food, Pedigree, Iams and Science Diet. Is the best dog food located in this group? Not likely.

2. Raw Dog Food: This is the group growing in popularity. It includes the raw dog food and bones you prepare yourself or pre-packaged diets like BARF and Steve's Real Food 100% natural dog food diet.

3. Homemade Dog Food: Anything you put together yourself at home. Is following good homemade dog food recipes the best choice for our dogs?
