Every review on our website includes an exact and detailed explanation for how we arrived at a particular star rating.

Corn is not a toxic ingredient. Many good dog foods contain some corn. It’s only considered “controversial” because different people have different opinions about it. That’s all. Nothing to worry about.

If you’re wondering WHY Diamond Premium isn’t an Editor’s Choice dog food…

I actually like Diamond products. They produce some of the very best value foods on the market… Diamond brand, Kirkland (Costco), Taste of the Wild and many others, to name a few.

Please keep in mind that currently, there are more than 340 dog foods rated 4 stars or higher on our website. And each one contains (on average) about 4-5 individual products (flavors).

However, by design, Editor’s Choice includes a much smaller selection. Currently, just 73 brands and sub-brands and about 140 suggested products. Having a smaller number to pick from is one of the very best benefits of being a member.

By the way, these numbers can vary from month to month as we add and remove various selections.

There are many reasons a particular brand may not be included on our lists.

For example, in most cases, a company may not have met all our published guidelines. Or more rarely, its agents may have been unwilling to reveal important manufacturing information.

Or we may be aware of unfavorable information about a company that we cannot share publicly (for liability reasons).

Or we may have received tips from industry insiders that disqualify certain brands from inclusion on our lists.

In any case, you should be able to find a more detailed answer to your question and many others on our Editor’s Choice FAQ page as well as our How We Rate Dog Foods FAQ page, too.

Hope this helps.
