Is the dcm cases in dog food related to only grain free?

Hey Will!

Thanks for your question. At this time they haven't figured out the science between DCM and grain free foods, however, to your point and to answer your question, the common denominator is "grain free" in DCM cases where diet is a factor. So, as long as the diet you are feeding your pups isn't marketed or labeled as "grain free" you should be fine!
