Hi Patrick. I don’t have experience with GSD’s specifically, but I do know that large breed puppies have specific dietary needs. You have to have the correct amount and balance of calcium and phosphorous in the food or they could develop orthopedic issues. Also, you must not overfeed. Slow and steady growth is best. The large breed puppy nutrition thread is a great resource.

Hound Dog Mom, a very knowledgeable member made a list of foods appropriate for large breed puppy growth. All foods on the list are 4 or 5 stars. See here: https://docs.google.com/file/d/0BwApI_dhlbnFTXhUdi1KazFzSUk/edit
There are some affordable 4 and 5 star foods that won’t break the bank. You can get the best selection and price by ordering online. I like Chewy.com and Petflow.com. Both ship free with a $49 order. The most affordable foods with grain from the list are: Dr. Tim’s Kinesis, Nutrisource Large Breed Puppy, and Victor Select (Chicken & Rice or Lamb & Rice). The most affordable grain-free is Earthborn Holistic (Meadow Feast or Coastal Catch). Other grain-free foods I would consider are Wellness Core Puppy and Nature’s Variety Instinct Turkey. Grain-free foods are more expensive but you can offset the cost of feeding grain-free by alternating with grain-inclusive foods as long as your dog tolerates both. It’s best to rotate through different foods and not feed the same thing all the time. I hope this helps. Someone else may chime in and give you more specifics about GSD’s specifically.
