I have read lots of research on many dog foods, so theres not to many top dog foods that im unaware of, however I have a golden lab (they dont have a "white lab")but a fifth generation ..so she is as white as a piece of paper..I have been feeding her natures logic sardine(because of the oils from tge fish)and I can honestly say that her coat and skin is so shiny and soft, its amazing!! I wont be switching dog foods and now that I have found this website, I will be purchasing it here ( due to the fact that I have been paying almost 75.00 at the local store that carries it)..If you buy this dogfood you wont regret it!!!
