Using puppy food for any puppy is essential to it's proper development. For large breeds, such as GSD, you must feed large breed puppy food.
HD is a common complaint for any large dog that's grown too fast for it's bones. This is why properly monitored feedings is so important. I recommend following the Vet's instructions, and if there's a breeder in the backdrop, follow their advice too. Prematurely stopping the feeding of puppy food to a large breed can cause physical problems down the road.
