I would agree that food rotation is best. I would find at least two other brands (more is better) of foods you like and start rotating them. From what I heard, vets only take one class is nutrition. The rest of their information on dog food comes from sales reps of the companies that they sell (Hill’s Science, Eukanuba, Purina, etc). My vet plainly admitted to me that he knows nothing about the new natural or holistic dog foods on the market today. He recommends Purina! Ew! The only way they will know is if they do the research themselves.
I wouldn’t feed my dog Hill’s or Eukanuba. I think Blue is a much better food than those two. To minimize the vitamin/mineral deficiencies or abundances found in Blue, I would rotate brands of food used. I don’t think there is any reason for you to panic about using Blue. I’ve used it for one of my dogs with no problems.
