Pork Limited Ingredient Formula Dry Dog Food, 25-lb bag
Graded by The Sniff System
Zignature Pork Limited Ingredient Formula Dry Dog Food is a dry food that features pork as its main protein source.
This formula uses pork as its primary protein, offering good amino acid coverage. It pairs fresh pork with pork meal, which is a solid approach for dry food. You'll also find premium micronutrient forms like chelated minerals.
The main thing to note is the absence of an AAFCO statement, which means its nutritional completeness is unverified. Also, there's a high amount of legume stacking, with peas, pea flour, and chickpeas all in the top five ingredients.
Good fit for dogs needing a limited ingredient diet with pork. Less ideal if you prioritize AAFCO verification or high legume content.
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 adult Labrador Retrievers and similar active sporting breeds navigating weight management. At 405 kcal/cup this formula runs on the rich side, with crude fiber at 4% (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 56/100, this formula lands mid-pack. The lift comes from protein quality, worth 16.5 points to the final number: Reasonable protein quality. pork 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.

Surfaced from a vector similarity search across 3,491 scored dog foods. How this works.
Read why each ingredient is good or bad for dogs.
- 1protein animalpork
Real meat. Dense protein and fat, though less common in dog food than chicken or beef.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animalpork meal
Pork cooked into a dry concentrate. Per pound, more protein than fresh pork.
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.
- 6pork fat
Real animal fat from a named species. Clean energy source.
Position 6: supporting protein. Modest contribution to total protein weight.
- 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.
- 8othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.

Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
