The first ingredient in this dog food is chicken broth. Broths are nutritionally empty. But because they add moisture to a dog food they are a common finding in many canned products.
The second ingredient is chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1
Chicken is naturally rich in all ten essential amino acids required by a dog to sustain life.
The third ingredient is chicken liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.
The fourth item lists potato starch. Potato starch is a gluten-free carbohydrate used here more for its thickening properties than its nutritional value.
The fifth item is lamb. Like chicken, lamb is another protein-rich meat.
The sixth item is salmon. Salmon is a fatty marine and freshwater fish not only high in protein but also omega 3 fatty acids, essential oils needed by every dog to sustain life.
After lamb liver and turkey, we note the inclusion of wheat gluten. Gluten is the rubbery residue remaining once wheat has had most of its starchy carbohydrate washed out of it.
Compared to meat, glutens are inferior plant-based proteins low in some of the essential amino acids dogs need for life.
This inexpensive plant-based ingredient can significantly boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.
The tenth ingredient is egg product, a dehydrated form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that have failed to hatch.
In any case, eggs are easy to digest and have an exceptionally high biological value.
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 four notable exceptions…
First, 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.
Next, tomato pomace is another 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.
Thirdly, avocado powder, a dried by-product obtained after removing all the oil from the fruit.
Avocado can be somewhat controversial.
Supporters claim the ingredient to be nutrient rich and beneficial to a dog’s skin and coat — while others worry over what are mostly unsubstantiated concerns over potential toxicity.
These fears appear to originate from a 1984 study in which goats (not dogs) consumed the leaves (not the fruit) of the Guatemalan (not the Mexican) avocado and became ill.2
Based upon our own review of the literature, it is our opinion that the anxiety over avocado ingredients in dog food appears to be unjustified.
And finally, this 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.
Nutro Ultra Canned Dog Food
The Bottom Line
Judging by its ingredients alone, Nutro Ultra looks to be an above-average canned dog food.
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 40% and an average fat level of 25%. Together, these figures suggest a carbohydrate portion size of 27% for the full product line.
And a fat-to-protein ratio of about 64%.
Near-average protein. Above-average fat. And near-average carbs when compared to a typical canned dog food.
However, when you consider the protein-boosting effect of the wheat gluten, this looks like the profile of a canned dog food containing only a moderate amount of meat.
Nutro Ultra canned dog food is a meat-based wet product using a moderate amount of chicken as its main source of animal protein, thus earning the brand 4 stars.

Rice ingredients can sometimes contain arsenic. Until the US FDA establishes safe upper levels for arsenic content, pet owners may wish to limit the total amount of rice fed in a dog's daily diet.
