Red items when present indicate controversial ingredients
The first ingredient in this dog food lists chicken. Although it is a quality item, raw chicken contains about 80% water. After cooking, most of that moisture is lost… reducing the meat content to just a fraction of its original weight.
After processing, this item would probably occupy a lower position on the list.
Which brings us to chicken meal… the second and (more likely) the dominant meat ingredient in this dog food.
Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The third item is brown rice. Brown rice is a quality ingredient… a complex carbohydrate that (once cooked) is fairly easy to digest.
The fourth ingredient is barley. Barley is a starchy carbohydrate supplying fiber and other healthy nutrients. Unlike grains with a higher glycemic index (like rice), barley can help support stable blood sugar levels in dogs.
The fifth ingredient lists chicken fat. Chicken fat is obtained from rendering chicken… a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.
Chicken fat is high in linoleic acid… an omega-6 fatty acid essential for life. Though it doesn’t sound very appetizing, chicken fat is a quality ingredient.
The sixth item mentions white rice… a less nutritious form of rice in which the grain’s healthier outer layer has been removed.
The seventh ingredient is oatmeal… a whole-grain product made from coarsely ground oats. Oatmeal is naturally rich in fiber and B-vitamins. And it’s also gluten-free.
Fish meal is another high-protein meat concentrate.
Unfortunately, this particular item is anonymous. The term “fish” does little to properly describe this ingredient.
Fish meal is commonly made from the by-products of commercial fish operations.
What’s more, the controversial chemical ethoxyquin is frequently used as a preservative in fish meals.
But because it’s usually added to the raw fish before processing, the chemical does not have to be reported to consumers.
We find no public assurances from the company this product is ethoxyquin-free.
Without knowing more, and based upon this fish meal’s location on the list of ingredients, we would expect to find at least a trace of ethoxyquin in this product.
Beet pulp is a controversial ingredient… a high fiber by-product of sugar beet processing.
Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.
We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most dog foods is entirely acceptable.
After the natural flavors, we find flaxseed… one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also rich in soluble fiber.
From here, the list goes on to include a number of other items.
But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to have much of an effect on the overall rating of this product.
With three notable exceptions
First, the manufacturer appears to have applied friendly bacteria to the surface of the kibble after cooking. These special probiotics are used to enhance a dog’s digestive and immune functions.
Next, this dog food also contains chelated minerals… minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.
And lastly, we’re pleased to report the product no longer appears to contain menadione.

NutriSource Dry Dog Food
The Bottom Line

Judging by its ingredients alone, Nutrisource dry dog food appears to be an above-average kibble.
But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.
The dashboard displays a dry matter protein reading of 29%, a fat level of 18% and estimated carbohydrates of about 45%.
As a group, the brand features an average protein content of 29% and a mean fat level of 17%. Together, these figures suggest acarbohydrate content of 46% for the overall product line.
Average protein. Near-average fat. And below-average carbs… as compared to a typical dry dog food.
If we ignore the fact that three of the foods still use corn gluten meal to boost their protein percentages, this looks like the profile of a kibble containing a moderate amount of meat.
Bottom line?
NutriSource dry dog food is a grain-based dry dog food using a moderate amount of chicken or lamb meals as its main sources of animal protein… thus earning the brand four stars.
Highly recommended.

What’s more, for those on a tight budget, the brand’s notably low price makes it an especially good value.
