Gary, I read that web site before and from my own personal experience, knowledge of kibbles and kibble manufacturing processes and animal rendering plants, there is truth in it and there is also hype and propaganda. It's like most of the things that you'll read about kibble diets vs, BARF vs other natural diets, each method has their own "nutritional experts" who can make arguments for each of the many feeding strategies and against the others. I mean I've even seen ludicrous arguments on web sites that kibbles should be fed to captive wolves instead of raw meats. I've also seen healthy looking dogs that are in their mid teens that have been fed nothing but really garbage low quality kibbles. So I would recommend to everybody not to believe everything that you read on the internet and recognize that the truth usually lies somewhere in between.
