I saw an episode where he skirted the edge of the food issue with a family. The dog was overweight, and so were the people. He recommended more exercise, of course, and a healthier diet. When he talked about diet, he tied it in with what the people were eating... as in, they could share certain healthy foods with their dog. He mentioned bits of chicken, steak, certain veggies... alllllmost like recommending a BARF type diet without outright mentioning BARF. I highly suspect that he has to watch his step with certain sponsors. A shame he has to limit himself to tiny hints like that.
