Hi AK-
Here is an article that is found on the review side of this website. It explains how it is best to keep calcium under a certain percentage to help prevent joint problems such as, hip and elbow dysplasia: /best-dog-foods/best-large-breed-puppy-food/
There is a calculator on the link helping you decipher whether a food is appropriate or not. Also states, that while not as precise, you can generally look for a food that has .9% to 1.35% calcium. I would be more concerned about that percentage than how many stars a food has at this stage of the puppies life. At least for a few more months until she is fully grown.
Pitlove and Frank have given you a few good options. Good luck with your choice. I know it is confusing, but you are on the right track!
