Freestyle Grain-Free Salmon & Peas Recipe Dry Dog Food, 26-lb bag
Graded by The Sniff System
Nulo Freestyle Grain-Free Salmon & Peas Recipe is a dry dog food with salmon, turkey, and fish as its main protein sources.
This food has a strong protein profile, with salmon as the first ingredient, which means good biological value for your dog. It also includes quality named fat sources like chicken fat, and diverse protein from fish meal and turkey.
The formula does contain multiple pulse-family ingredients like peas, chickpeas, and lentils in the top 15, which is a pattern the FDA has noted in its DCM investigation.
Good fit for adult dogs who thrive on a fish-based, grain-free diet. Less ideal if you prefer foods without multiple legumes.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for lower-energy small companion breeds like French Bulldogs, Bulldogs, and Boston Terriers navigating a sensitive stomach. Salmon leads at position 1. Worth watching: multiple protein sources stacked (harder to isolate triggers). Frenchies have notoriously sensitive GI tracts plus a tendency toward obesity given their low activity needs. Limited-ingredient formulas with moderate calorie density tend to fit them well.

Sniff scored this formula 64/100, landing in B-tier territory. The biggest contributor was protein quality (+21.5 points): Strong protein profile with salmon as the primary ingredient, delivering high biological value. The biggest detractor was controversial-ingredient penalty (-2 points): Contains high legume stacking. Multiple pulse-family ingredients in top 15. Mitigated by taurine supplementation or organ meat (natural taurine precursor) in top 10. To reach A-tier, this formula would need to gain about 11 points, most likely through controversial-ingredient penalty.

Read why each ingredient is good or bad for dogs.
- 1protein animalsalmon
Real fish meat. Natural source of omega-3s, which kibble usually has to add back from oil.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animalturkey meal
Turkey with the water cooked out. Per pound, packs more protein than fresh turkey. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3protein animalfish meal
Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile. See why →
Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 4legumepeas
Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →
Position 4. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 5vegetablesweet potato
Complex carb with fiber and beta-carotene. Gentle on the stomach.
Position 5: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 6fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7legumechickpeas
Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →
Position 7. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 8legumelentils
Same concern as peas. Affordable plant protein, but when they pile up in the top 5 ingredients, it's a flag. See why →
Position 8. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 9protein animalturkey
Real meat. Lean protein, good amino acid profile, often well-tolerated by dogs sensitive to chicken.
Position 9: supporting protein. Modest contribution to total protein weight.
- 10fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 10. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 11othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 12dried tomatoes
Real fruit. Lycopene and trace antioxidants. Different from tomato pomace, which is the fiber byproduct.
- 13yeast culture
Fermented yeast. Source of B vitamins and beta-glucans that some research suggests support immune function.
- 14mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 15mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 16supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18fiberdried chicory root
Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.
- 19supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 20vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 21dried apples
Real fruit, some fiber and antioxidants. The amount in kibble is too small to matter much.
- 22fruitblueberries
Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.
- 23vegetablecarrots
Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.
- 24mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 25mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
