DEAR READERS: Dr. Karen Shaw Becker, noted veterinarian, has posted an alert at healthypets.mercola.com relating to pet food recommendations. Recently, Ryan Yamka, Ph.D., founder of Luna Science and Nutrition and the Guardian Pet Food Co., took an in-depth look at WSAVA’s recommendations and found them lacking. He determined they provide a false sense of security to anyone offering pet food advice based on the association’s criteria.”For more details, go to healthypets.mercola.com. I also recommend ordering Susan Thixton’s annual Truth About Pet Food List (truthaboutpetfood.com/the-list). I would add another concern -- not a conspiracy theory, but reality -- about the link between the pet food and pharmaceutical industries.
