There is a financial interest here and that belongs to those that are charging for BS treatments that have no proven scientific effect. Show me one double blind study that shows a proven benefit to feeding raw diets, not just hear say. Name one nutrient that been discovered in raw diets that is not present in cooked diets. I would also mention that is not possible feed a complete diet containing all the nutrients dogs need daily without adding a supplement. Can you define "ancestral diet". Americans love to be sold "miracle cures". Here's to Lydia Pinkham!
