I had my pit and pit mix on Nutro Natural Choice Lamb and Rice. Then once I started researching Nutro I found some very upsetting information. I then decided to start them on a more natural food and bought Blue Buffalo. One of my dogs did well on it while the other one was had a horrible reaction to it and vomitted to the point on needing IV fluids from the vet. So, after than incident a talked to my Vet and put them on Science Diet. I am still searching for a better alternative but they both do well on Science Diet.
