Hi Darien-
Consider keeping him on Pro Plan Large Breed Puppy. Despite what folks on the internet say about Purina they have poured millions of dollars into researching the growth patterns and nutritional needs of large breed puppies. This food is one of the best and safest to feed to ensure optimal growth and lean body condition when fed to the feeding guidelines and activity level of the dog.
Regardless what you choose he will need to stay on Pro Plan for 3-4 weeks after you get him before switching.
