I don’t have near the experience you do, but I went to 95% raw meat (mostly scrap stuff) since last fall with my 2yr old lab and so far it’s been great. I kept all the wild game scraps I had and I live about a half mile from a butcher who sells course ground trim stuff for $1 a pound. I give him about a pound and a half a day with with the occasional raw egg etc. And do a little cooked rice/vegetables every other day or so.. I definitely don’t get to scientific about it but he’s very happy and healthy and loves it. And yes he poops less!Local butcher shop sells raw dogfood. Its evrything from deer, pork, beef, lamb, goat, etc. Fat, tendons, everything they cut out when processing. It's cheaper then most of these high end, cooked out, dry dogfoods!
