@SamaHoole This literally happened when our dog had an itch and terrible skin problems. We took him to the vet. First question: what are you feeding him? Immediate solution: change the protein source. It worked!
@basedethos Are any animals left out for convenience, because otherwise the result would be different, like in the 7 nations study where they had data for 21 countries but only used 7 that fitted the narrative?
