Thomas,
Here in the forums, go to the “Diet & Health issues” forum. On top, highlighted in yellow, is a thread about large breed puppy nutrition. Its very long but I suggest you start from the most current page (highest number) and work backword to find the list of approved foods for large breed puppies.
Also, you’re on the internet so you have access to almost any food by ordering online. Most of us do. I suggest Chewy.com because of theor awesome return policy. Other good sites are PetFlow, Wag and PetFoodDirect.
