We use PPP for our 4 dogs with great results. That website is useful for explaining what is in the food, but has no bearing on the long track record of success of PPP. Also, for what it's worth, there are a lot of great options for raw feeding too. We typically supplement the kibble with venison (we kill ~dozen whitetails a year) and chicken leg quarters when they're clearance priced at 50 cents a pound. There's a lot of good options, but in the end it all comes down to how the dog performs on the food your using. If it's good stick with it, if not, change it up, IMO.
