The report was a compilation of all the reported cases of DCM (dilated cardiomyopathy). The way these things are done is to extensively question owners about EVERYTHING and then evaluate any statistical relevent coincidences. The next step is to find out why.
I'd say the brand is not as important as the ingredients. I don't feed my dogs (and don't recommend) grain free foods unless there is a specific reason (celiac disease or allergies to specific grains).
According to the data, 91 percent of the cases were on grain free foods and most of those were pea/lentil as a component.
