Salmon, brewers rice, canola meal, oat meal, fish meal (natural source of glucosamine), animal fat preserved with mixed-tocopherols (form of Vitamin E), salmon meal (natural source of glucosamine), pearled barley
That to me shows that there is actually more grain in the dog food than there is meat. Not a good thing for a meat-eater. Salmon may have the most on its own, but clearly there is more grain than there is actually meat.
That, and the fact that they simply list "animal fat" - that's a no-no for me when it comes to deciding on a food. If I don't know what animal it comes from, then I'm not about to feed that food. Personally.
Contrast that to a medium-quality food, Chicken Soup for the Dog's Soul:
Chicken, turkey, chicken meal, ocean fish meal, cracked pearled barley, whole grain brown rice, oatmeal, millet, white rice, chicken fat (preserved with mixed tocopherols), potatoes, egg product, tomato pomace, duck, salmon, flaxseed, natural chicken flavor, potassium chloride, salt, choline chloride, dried chicory root, kelp, carrots, peas, apples, tomatoes, blueberries, spinach, dried skim milk, cranberry powder, rosemary extract, parsley flake, yucca schidigera extract, L-carnitine, dried fermentation products of Enterococcus faecium, Lactobacillus acidophilus, Lactobacillus casei and Lactobacillus plantarum, dried Trichoderma longibrachiatum fermentation extract, vitamin E supplement, iron proteinate, zinc proteinate, copper proteinate, ferrous sulfate, zinc sulfate, copper sulfate, potassium iodide, thiamine mononitrate, manganese proteinate, manganous oxide, ascorbic acid, vitamin A supplement, biotin, calcium pantothenate, manganese sulfate, sodium selenite, pyridoxine hydrochloride (vitamin B6), vitamin B12 supplement, riboflavin, vitamin D supplement, folic acid.
Of the first five ingredients - which are the most important, four are meat ingredients, then followed by the grain products. That food is one in which there is more meat than grain. There are also probiotics to assist in digestion of the food, which is a plus.
Then you could even go to an even higher-quality food (read: expensive) that would be even more limited in the additives and even lower in grain content, even to go to the grain-free recipes.
Purina is definitely better than, say, Beneful or Kibbles N' Bits, but it's not really that high on the "quality" scale overall. Yes, lots of dogs do "okay" on these diets for years and years and years - but some people also do "okay" on fast food diets and no fruits or vegetables at all in their diets...."okay" doesn't mean that it's optimal. And that's all people mean when they talk about "top-quality" foods. Quality is about the quality of the ingredients, the quality of the preservatives used to keep that food healthy, and the methods in which the food is made.
Feeding dogs "well" is expensive, just as eating "well" yourself is more expensive than eating garbage foods. Those fruits and veggies alone rack up quite a bit in a budget, let alone good lean meats! Not everyone can afford to feed their dogs the best food - it happens - but it doesn't mean that it's still the best food in the long run either.
