In 1990s, I used to feed Nutro. At that time, Nutro was good (at that time).... used mostly known meat meal (like lamb meal) as the first ingredient, used sunflower oil as its only source of fat, I remember the high content of linoleic acid (over 4 %) because my black lab's coat used to shine like you would not believe and I got a lot of compliments. Here is the ingredient list of Natural Choice Lamb and Rice as of 2001 (I can't find older archived records then 2001):
Lamb Meal, Ground Rice, Rice Bran, Rice Flour, Sunflower Oil (preserved with mixed Tocopherols, a source of natural vitamin E), Rice Gluten, Dried Egg Product, Natural Flavors, Monosodium Phosphate, Dried Kelp (source of Iodine), Choline Chloride, Vitamin E, Supplement, Zinc Sulfate, Ascorbic Acid (source of vitamin C), Niacin, Glucosamine, Hydrochloride, Ferrous Sulfate, Calcium Pantothenate, Chondroitin Sulfate, Vitamin A Supplement, Manganous Oxide, Thiamine Mononitrate (source of vitamin B1), Vitamin D3, Supplement, Riboflavin Supplement (source of vitamin B2), Vitamin B12 Supplement, Pyridoxine Hydrochloride (source of vitamin B6), Inositol, Folic Acid, Biotin.
yes... the rice gluten... but it was high enough on the ingredient list.

Slowly, (1) known meat meal (like chicken meal) is reduced and meat (like chicken) is added. Pound for pound, I prefer chicken meal over chicken, as 1 pound of chicken meal contains more protein than 1 pound of chicken (once the water is removed). (2) sunflower oil is reduced and poultry fat is added, and (3) content linoleic acid is reduced. Here is the ingredient list of Natural Choice Lamb and Rice as of 2005:
Lamb Meal, Ground Rice, Rice Flour, Rice Bran, Sunflower Oil (preserved with mixed Tocopherols, a source of natural Vitamin E), Poultry Fat (preserved with mixed Tocopherols, a source of natural Vitamin E), Natural Flavors, Rice Gluten, Dried Egg Product, Dried Beet Pulp, Potassium Chloride, L-Lysine, Dried Kelp (source of Iodine), Salt, Choline Chloride, Zinc Sulfate, Vitamin E Supplement, Taurine, Ferrous Sulfate, Ascorbic Acid (source of Vitamin C), Biotin, Copper Proteinate, Niacin, Manganous Oxide, Calcium Pantothenate, Vitamin B12 Supplement, Riboflavin Supplement (source of Vitamin B2), Vitamin A Supplement, Glucosamine Hydrochloride, Chondroitin Sulfate, Pyridoxine Hydrochloride (source of Vitamin B6), Thiamine Mononitrate (source of Vitamin B1), Vitamin D3 Supplement, Menadione Sodium Bisulfite Complex (source of Vitamin K activity), Calcium Iodate, Folic Acid.

NOW, after acquisition by Mars (I believe it was in 2007), and latest changes made by Nutro (in 2008).... reduce known meal meal (see where lamb meal is now), add lamb (it is now #1 ingredient), add more grain (see brown rice), add grain/vegetable based proteins (potato protein, pea protein, and rice protein concentrate), add soybean oil (cheaper source of linoleic acid) further reduce sunflower oil..reduce egg product and etc. Here is the ingredient list of Adult Natural Choice Lamb and Rice ( I just got it off Nutro's website) as of end of 2008:

I personally would not feed my current lab Nutro anymore. It is not the Nutro that I used in 1990s. I also do not want to pay premium prices for grain and vegetable proteins............when the advertising, in this case, is for lamb and rice or chicken and rice.
I was one of Nutro's biggest fan. The last time I bought Nutro was 2001. Now that I know better.
