[Dog_Obsessed]

I’m so sorry for your lose. Southern States Advanced is not a particularly high-quality food here is the link to the DFA review: /dog-food-reviews/southern-states-advanced/

Don’t blame yourself, it was recommended to you and is marketed to be a good food. It sounds like you already tried reporting this to the FDA. You might want to keep trying, to see if they will eventually listen. If you know anyone else who had a similar experience, ask them to report it also.
