I watched that show and I was stunned to see Oprah refusing to let her own expert guest talk. He was trying to present a graph showing the best food for dogs - natural prey (rabbits, birds etc) was first, raw meat, offal and bones was 2nd and lower end dry food was last.
The vet read through this list and said several times that dogs are carnivores and should be fed raw meat and bones. Oprah then showed everyone what she fed her dogs which was cooked chicken, rice, potato and other vegetables. She totally discounted what this man was saying and even commented that she couldn't deal with the thought of raw meat.
I don't understand how what Oprah wants to eat reflects on what her dogs should be eating!! Not only did she disregard all the research her guest (and I believe personal vet) had done into the subject, the only thing that people seem to remember is her 'recipe'. What about the fact that while saying she agreed with the information that was presented she then invalidated everything based on her personal preference?
The vet did not recommend this cooked meat, grain and vegetable diet, Oprah did.
