Steve Brown, of Steve's Real Food For Dogs (one of the commercial diets analyzed in this study) is in a huge battle with the JAVMA and the researchers over this. There are several discrepancies in their data and his own, as far as nutrient levels, etc. They have not agreed to print a disclaimer, and in fact they have not publicized who actually funded the study (which they are required by law to do). Steve's been in touch with my friend who was at a Purina seminar where they freely (and proudly!) admitted they funded the study....we'll see what develops.
I've learned to just turn a deaf ear to those who want to argue with me about feeding a raw diet (except on this board, of course
) - I know I am doing the right thing for my dogs, and maybe when their 5 and 6 year olds continually die of cancer they'll think about what I've said.
