Yes, this has been all over the internet for a few months now. Grain Free probably isn't the way to go unless your dog absolutely needs it, and honestly, most don't have grain allergies. I have an 11 year old on a GF and only because it's one of the few that I can find that is 100% chicken-free and that he does well on. I am not too worried about his heart. Plus some of the offending ingredients are not really present in his food. His is potato heavy vs. legume heavy.
