What's actually in Nutro?
We analyzed Nutro Wholesome Essentials Adult Chicken, Brown Rice & Sweet Potato. The first ingredient is chicken — whole, named animal protein. Chicken meal follows at position two, adding concentrated protein. Two chicken-based proteins before the first carbohydrate is a genuinely strong opening that most mid-tier brands can't match.
Then comes the rice. Whole brown rice at position three, brewers rice at four, rice bran at five. That's three forms of the same grain occupying three of the top five ingredient slots. This is classic ingredient splitting — by listing whole brown rice, brewers rice, and rice bran separately, each one appears lower on the list than if they were combined as a single "rice" entry. Combined, rice is almost certainly the dominant ingredient in this formula by weight.
Further down: dried plain beet pulp (fiber), chicken fat, natural flavor, pea protein at position ten, sweet potato, sunflower oil, and rosemary extract for natural preservation. The ingredient list is short and relatively clean — no corn, no wheat, no soy, no artificial preservatives. Shop on Amazon →
The good stuff
Chicken and chicken meal in positions one and two is a legitimate protein foundation — and it's the main reason Nutro scores as well as it does. Whole chicken provides fresh animal protein with natural moisture, while chicken meal delivers concentrated protein that's been rendered down. Together, they give this formula a protein opening that genuinely outperforms most of the competition at this price point.
No corn, no wheat, no soy, no artificial colors, flavors, or preservatives. Nutro's "clean recipe" marketing isn't just spin — the formula genuinely avoids the worst filler ingredients that plague its Mars siblings like Iams (C/63), Royal Canin (C/58), and Pedigree (D/37). The gap between Nutro and those other Mars brands is enormous.
Rosemary extract for natural preservation is a proven antioxidant that avoids the BHA/BHT concerns of cheaper formulas. Dried plain beet pulp is a quality fiber source that supports digestive regularity without adding sugar (despite the name, plain beet pulp has the sugar removed). Sweet potato adds nutrient density and complex carbohydrates. The formula is grain-inclusive, which avoids the DCM concerns associated with legume-heavy grain-free diets.
The not-so-good stuff
The rice ingredient splitting is the most significant issue. Three rice-derived ingredients in the top five — whole brown rice, brewers rice, and rice bran — means this formula is rice-heavy in a way the ingredient list obscures. Brewers rice in particular is a lower-quality rice by-product: the small, broken fragments left over after milling. It's cheap filler that adds carbohydrate bulk without the nutritional profile of whole grains.
There is no omega-3 source anywhere in this formula. No fish oil, no salmon oil, no flaxseed, no fish meal. For a dog food at this price point, the complete absence of omega-3 fatty acids is a real gap. Omega-3s support skin health, coat quality, joint function, and cognitive health — most competing formulas include at least flaxseed. Sunflower oil provides omega-6 but does nothing for the omega-3 side of the equation.
No probiotics, no prebiotics, no functional superfoods. Pea protein at position ten is a plant-based protein booster — it inflates the guaranteed analysis protein percentage without the complete amino acid profile of animal protein. These are the gaps that keep Nutro from scoring higher within the B tier.
How it compares
At B/77, Nutro is the surprise performer of the Mars portfolio. While its corporate siblings languish in C, D, and F territory — Royal Canin (C/58), Iams (C/63), Pedigree (D/37) — Nutro earns a legitimate B grade on the strength of its protein foundation and clean ingredient list. The "clean recipe" positioning isn't just marketing; it translates to a meaningfully different formula.
Nutro competes directly with the established B-tier value picks. Blue Buffalo Life Protection Formula (B/78) edges it out by a single point with omega-3 sources and antioxidant-rich fruits. Diamond Naturals (B/78) also scores one point higher — with probiotics, superfoods, and salmon oil that Nutro simply doesn't include. But the margin is slim, and Nutro's PetSmart availability makes it one of the most accessible B-grade foods on the market.
Compared to Hill's Science Diet (C/61) — the other big-box staple — Nutro delivers 16 more points of nutrition for a similar price. If you're already shopping at PetSmart and comparing bags, Nutro is the better pick by a wide margin.

Life-stage variant: Nutro Wholesome Essentials Puppy (B/78) scores one point higher than the adult formula by adding fish oil DHA, lamb meal for protein diversity, dried sweet potato, and chelated mineral forms while maintaining Nutro's clean-label discipline.
The bottom line
Nutro Wholesome Essentials earns a B grade (77/100) from KibbleIQ. Chicken first and chicken meal second provide a strong protein foundation that most Mars brands can't touch, and the formula genuinely avoids artificial additives, corn, wheat, and soy. The triple rice splitting and missing omega-3s are real caveats — but they're not enough to drag down what is otherwise a solidly above-average dog food. This is a Mars brand that actually delivers, and one of the best options you'll find on a PetSmart shelf. Shop on Amazon →
