RE: New Pro Plan with "Shreds"
Personally, I find that site almost completely worthless. It clearly has an agenda to push no-grain feeds. The reviewers are not animal nutrition experts, even by their own admission. It is just a group of people pushing their personal opinions and not what is necessarily correct.
I say almost completely worthless as the site does have a very complete list of feeds and their ingredients. If you get a kick out of dog food, this is a good source to look at in figuring out, perhaps, which ingredients work best with your dog.
Other than that, it is propaganda at it's purest form.
