Large breed puppies have special nutritional needs, which you can learn more about in this article: /best-dog-foods/best-large-breed-puppy-food/
There is also a topic about this in the forums: /forums/topic/large-and-giant-breed-puppy-nutrition/#post-62904
If you go to page 15 and scroll down, there is a post by Hound Dog Mom with a google doc containing a list of acceptable foods.
As for your other dog, look around at the reviews of four and five star reviews and choose a few brands. Study the brand’s recall history to make sure they are not recently or frequently recalled. If they are not available locally, then you can order online, some sites that are popular are chewy.com pet flow.com. Stay away from doggiefood.com. It is best to have several brands and formulas to rotate between, because no dog food is perfect.
Good luck, I know it can be overwhelming and confusing looking for good dog food. Feel free to ask any questions!
