Hi LeahT –
You vet obviously knows very little about nutrition, this is expected – vets receive minimal education concerning nutrition and what they do receive is funded by the big name corporations like Nestle (Purina), Mars (Royal Canin and Pedigree), Colgate-Palmolive (Science Diet) and Proctor and Gamble (Iams and Eukanuba). Purina and Pedigree are two of the lowest quality dog foods available. Personally, if I were in the situation you are in I would find a new veterinarian.
I would recommend checking out the following articles/videos from Dr. Karen Becker. Dr. Becker is a holistic veterinarian who is very knowledgeable about species-appropriate nutrition and alternative therapies:
