Purina Pro Plan for almost 30 years.
Go to dog food advisor on the internet. You'll be shocked at how low the big name foods (Science Diet, Nutro, etc.) are rated. I use Victor high energy formula for two 11 month olds and it's great. I used to feed Diamond but they've had some recent recalls. My pups are family so they get the best available.
Fromm Gold also!
