yes, they do studies but they don’t use them. If you would read a book like Unlocking the Canine Ancestral Diet and there are others.. this book written by a pro who formulated kibble for big companies. You would never feed that stuff. Dog’s lives are so short really.. if you would read it and see how this kibble could not be really good, that your dog could not really do really well.. The problem is that the AAFCO are not that great in terms of meaning the full, thriving kind of needs. They are a base line.. with too much carbs or not enough of the right fats, that the fats in there when cooked lose their potency etc. and are not high enough in protein that is actually good… No I don’t really trust purina.. Many people do studies, it doesn’t mean they make better dog food. Lots of studies have been done on people too to see what they can tolerate.. no. Don’t trust them.
