What are you feeding your akitas?

at our first vet appointment, the vet told us to get Purina pro plan food for our four month old American Akita. What are you American Akita owners feeding your dogs? I really want my dog to be healthy and I am open to other brands other than Purina pro plan. I looked into Buffalo blue but I read a lot about how it is linked to long-term health issues please help as a first-time American Akita owner! x
