Hi Norman-
At 9 months old, your puppy is not ready to be eating an adult maintenance formula because she is a large breed. Large breed puppies require a very specific diet to help reduce their risk for orthopedic disorders. Adult maintenance formulas are far too high in calcium for a large breed puppy.
You could either try the puppy formula of the Royal Canin Breed Specific formulas if you are interested in staying with RC or the Maxi Puppy formula. You may also look into Purina Pro Plan Large Breed Puppy. I find Pro Plan has very good digestability.
