Since the breeder our puppies fed to the 10 week this food also we chose Vollmer. However, our puppy had repeatedly bloating and diarrhea. In time, his coat of gloss lost and constantly had to scratch so that the flaked skin. So ask from the vet and his opinion. We have the feed then changed immediately and he also enjoys once a week, a baby bath. The new feed Vet-Concept is still in the testing phase. Unfortunately, this is not available on Amazon.
