Hi Kenneth-
Welcome to the forums. Hound Dog Mom hasn’t been able to post on here in quite some time due to school, so I don’t know that you’ll ever hear back from her. I can however, try to help.
Here is 2 articles from DFA that may help you understand large breed puppies and choosing a dog food a little better:
/best-dog-foods/best-large-breed-puppy-food/
/choosing-dog-food/brand-guidelines/
It is interesting that when you read through the second link the rating that Pro Plan recieves does not reflect those criteria that Mike has outlined. In fact Pro Plan makes a excellent choice when using those 9 tips. Another thing to be mentioned is that Purina is one of 2 companies that are the leaders in research for large breed puppy nutrition and growth. While some may choose other brands or diets other than kibble, many show dogs are fed Pro Plan as well. Personally, I see no reason to switch simply because this website rates it 2.5 stars, especially since you’ve noted your dog is doing quite well on it.
However, if you are insistant, I would highly recommend looking at Dr. Tim’s Kinesis (not the grain free one). It is formulated by both a vet and a nutritionist and has gone through AAFCO feeding trials and if star rating is of that much concern, it is rated 4 stars.
