Nutrisource is a good food. I think Victor would be good too. It is rated 4 or 5 starts and is reasonably priced. It can be found at some feed stores or online at sites like Petflow.com or Chewy.com. I would feed the Victor Select Hi Pro Plus (30% Protein). You can get it on Amazon- $55 for 40 pounds: http://www.amazon.com/Victor-Dog-Food-Formula-40-Pound/dp/B00CJLP4EA
I also like all of their grain-free formulas and would recommend any of them.
