Nutro Ultra Dog Food receives the Advisor’s second-highest tier rating of 4 stars.
The Nutro Ultra product line includes 10 dry dog foods.
Each recipe below includes its related AAFCO nutrient profile when available on the product’s official webpage: Growth, Maintenance, All Life Stages, Supplemental or Unspecified.
Important: Because many websites do not reliably specify which Growth or All Life Stages recipes are safe for large breed puppies, we do not include that data in this report. Be sure to check actual packaging for that information.

The first ingredient in this dog food is chicken. Although it is a quality item, raw chicken contains up to 73% 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 account for a smaller part of the total content of the finished product.
The second ingredient is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The third ingredient is brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.
The fourth ingredient is brewers rice. Brewers rice is a cereal grain by-product consisting of the small fragments left over after milling whole rice. Aside from the caloric energy it contains, this item is of only modest nutritional value to a dog.
The fifth ingredient is rice bran, a healthy by-product of milling whole grain rice. The bran is the fiber-rich outer layer of the grain containing starch, protein, fat as well as vitamins and minerals.
It’s important to note that a number of ingredients included in this recipe are each a type of rice product:
- Brown rice
- Brewers rice
- Rice bran
Although they’re a mixture of quality plant ingredients, there’s an important issue to consider here. And that’s the recipe design practice known as ingredient splitting.
You see, if we were to combine all these individual items together and report them as one, that newer combination would almost certainly occupy a higher position on the list — possibly making rice (not meat) the predominant ingredient in this recipe.
The sixth ingredient is lamb meal, another protein-rich meat concentrate.
The seventh ingredient is 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. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.
The eighth ingredient is salmon meal, yet another high protein meat concentrate.
Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.1
After the natural flavor, we find sunflower oil. Sunflower oil is nutritionally similar to safflower oil. Since these oils are high in omega-6 fatty acids and contain no omega-3’s, they’re considered less nutritious than canola or flaxseed oils.
Sunflower oil is notable for its resistance to heat damage during cooking.
There are several different types of sunflower oil, some better than others. Without knowing more, it’s impossible to judge the quality of this ingredient.
The next ingredient is oatmeal, a whole-grain product made from coarsely ground oats. Oatmeal is naturally rich in B-vitamins, dietary fiber and can be (depending upon its level of purity) gluten-free.
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 affect the overall rating of this product.
With eight notable exceptions…
First, flaxseed is 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.
However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.
Next, we note the use of pea protein, what remains of a pea after removing the starchy part of the vegetable.
Even though it contains over 80% protein, this ingredient would be expected to have a lower biological value than meat.
And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the meat content of this dog food.
In addition, we find chia seed, an edible seed nutritionally similar to flax or sesame. Provided they’re first ground into a meal, chia seeds are rich in both omega-3 fatty acids as well as dietary fiber.
However, chia seeds contain about 17% protein, a factor that must be considered when judging the meat content of this dog food.
Next, tomato pomace is a controversial ingredient, a by-product remaining after processing tomatoes into juice, soup and ketchup.
Many praise tomato pomace for its high fiber and nutrient content, while others scorn it as an inexpensive pet food filler.
Just the same, there’s probably not enough tomato pomace here to make much of a difference.
We also note the inclusion of beet pulp. 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.
Additionally, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
Next, this food 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, this recipe also includes selenium yeast. Unlike the more common inorganic form of selenium (sodium selenite), this natural yeast supplement is considered a safer anti-cancer alternative.
Nutro Ultra Dog Food Review
Judging by its ingredients alone, Nutro Ultra Dog Food looks like an above-average dry product.
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.
As a group, the brand features an average protein content of 28% and a mean fat level of 14%. Together, these figures suggest a carbohydrate content of 49% for the overall product line.
And a fat-to-protein ratio of about 51%.
Near-average protein. Below-average fat. And near-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the pea protein, flaxseed and chia seed, this looks like the profile of a kibble containing a moderate amount of meat.
Nutro Ultra is a grain-inclusive dry dog food using a moderate amount of named meat meals as its main source of animal protein, thus earning the brand 4 stars.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.
