Salmon Limited Ingredient Formula Dry Dog Food, 25-lb bag
Graded by The Sniff System
Zignature Salmon Limited Ingredient Formula Dry Dog Food is a dry food built around salmon as its primary protein.
Salmon is the primary protein, offering solid amino acid coverage. The formula uses both fresh salmon and salmon meal, which is a strong combination for dry food. This also means it includes named fish for diverse, high-bioavailability protein.
The biggest concern is the lack of an AAFCO statement, which means its nutritional completeness is unverified. There's also high legume stacking, with peas, pea flour, and chickpeas all appearing in the top ingredients.
Good fit for adult dogs who do well on a salmon-based diet. Less ideal if you require verified nutritional completeness.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. Good fit for active large sporting breeds like Labrador Retrievers, Golden Retrievers, and English Setters navigating weight management. At 405 kcal/cup this formula runs on the rich side, with crude fiber at 5% (above the catalog median, supports satiety). The 2014 AAHA Weight Management Guidelines define overweight as a Body Condition Score (BCS) of 6-7 on a 9-point scale. A score of 8 or 9 indicates obesity, representing 20-30% and >30% above ideal body weight, respectively (Brooks et al., 2014) .

At 57/100, this formula lands mid-pack. The lift comes from protein quality, worth 19.5 points to the final number: Reasonable protein quality. salmon delivers solid amino acid coverage. The ceiling on this score is 59, set because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). The fix path: the brand publishing the AAFCO statement. That would lift the cap and put this formula above the B-band line at 60.

- 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 animalsalmon meal
Salmon cooked into a dry concentrate. Carries both protein and natural omega-3s in one ingredient. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3legumepeas
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 3. Pulse-family ingredient this high in the deck is a notable build choice. When stacked with other pulses in the top 10, matches the formulation pattern the FDA flagged in its diet-associated DCM investigation.
- 4legumepea flour
Powdered peas, usually used as a binder or filler. Counts toward the legume stack the FDA flagged.
Position 4. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 5legumechickpeas
Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →
Position 5. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 6fatsunflower oil
Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.
Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 7: trace fat. Below the level that materially shifts the fat profile.
- 8dehydrated alfalfa meal
Dried alfalfa. Fiber and trace minerals. Not exciting but it's a real plant ingredient.
- 9othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 10mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 11mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 12supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 13vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 14vitaminvitamin a supplement

B vitamin (B5). Standard inclusion in complete dog foods.
- 17vitaminriboflavin supplement
B vitamin (B2). Required in complete dog foods. The standardized form ensures consistent dosing.
- 18vitaminthiamine mononitrate
B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.
- 19vitaminvitamin b12 supplement
Essential for red blood cell formation and neurological function. Plant ingredients lack B12, so it has to be added.
- 20vitaminpyridoxine hydrochloride
B vitamin (B6). Essential for protein metabolism. Standard inclusion in complete formulas.
- 21vitaminfolic acid
B vitamin (B9), essential for cell function. Standard in complete dog foods.

B vitamin that supports skin and coat health. Required for AAFCO-complete formulas.
- 23supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 24mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 25mineraliron proteinate
Iron bound to protein for better absorption. The premium form versus inorganic iron sulfate.
