An orthopedic surgeon is not a veterinary nutritionist. Their speciality is in surgery, not in nutrition. If you would like to hear it from the horses mouth, you can go to petdiets.com and under their “Ask the Nutritionist” section pose the question. Dr. Rebecca Remillard who is a boarded veterinary nutritionist has repeatedly on that site said that it is NO longer recommended to switch large breed puppies to adult foods at a young age. There is simply no reason to now that so many companies have created foods that meet the growth requirements for large breed pups. Back 30-40 years ago, this was not the case, so adult foods were used.
