I like the Dog Food Advisor web site and have recommended it to a lot of people. Including co-workers and even folks looking at dog food in pet supply stores and Walmart. I also tell them that if the choices seem bewildering, a quick easy way to get some notion of quality is to look at the first two ingredients. If the first two ingredients - three is even better - are meat and/or meat meal from identified sources of meat, it is likely that they are looking at one of the better kibbles available there. There's more to it than that, of course, but it is a great place to start. Interestingly, the big chain pet supply store in town carries virtually none of the better foods. Thankfully, the little mom and pop shop does.
