The scores
Stella & Chewy's Chewy's Chicken Freeze-Dried Raw Dinner Patties: A (90/100) — 95% chicken, chicken organs, and ground bone. Four probiotic strains. SecureByNature HPP documented.
Primal Pronto Beef Recipe Frozen Raw: A (90/100) — Beef with ground bone plus beef liver. Ten organic produce ingredients. Whole-food supplementation. HPP documented.
Both brands sit at A/90 under the Fresh Food Rubric v1.0 with explicit HPP documentation — the first two products in our catalog to clear the "+5 HPP bonus" raw-pathogen-control threshold.
How the ingredients compare
Stella & Chewy's (Chicken): Chicken with ground bone, chicken liver, chicken gizzard, pumpkin seed, organic cranberries, organic spinach, organic broccoli, organic beets, organic carrots, organic squash, organic blueberries, fenugreek seed — then mineral tail, four probiotic strains, and conventional vitamin complex.
Primal Pronto (Beef): Beef with ground bone, beef liver, organic squash, organic carrots, organic kale, organic apples, organic parsley, organic pumpkin seeds, organic sunflower seeds, organic blueberries, organic cranberries, organic broccoli, montmorillonite clay, organic apple cider vinegar, cod liver oil, fish oil, organic coconut oil, dried yeast, organic ground alfalfa, dried organic kelp, and taurine.
Both start with muscle-plus-bone plus organ meat. Stella & Chewy’s stacks a second organ (chicken gizzard at position three); Primal relies on a single liver position and shifts emphasis to a wider organic-produce layer (ten distinct organic fruits, vegetables, and seeds vs. Stella’s seven).
Where Stella & Chewy's pulls ahead
Shelf-stable convenience: Freeze-dried patties live in the pantry until you rehydrate them. No freezer space commitment, no thaw planning, no cold-chain shipping anxiety. For apartment dwellers, frequent travelers, and households without chest-freezer space, this is a meaningful lifestyle advantage.
Dual organ stack: Chicken liver at position two plus chicken gizzard at position three gives Stella & Chewy’s two distinct organ ingredients in the top three. Primal runs a single liver position. For owners specifically targeting ancestral-diet organ-meat density, Stella wins by a measurable ingredient count.
Probiotic density: Four distinct probiotic strains (pediococcus acidilactici, lactobacillus acidophilus, bifidobacterium longum, bacillus coagulans) at a guaranteed 50M CFU/oz minimum. Primal doesn’t add discrete probiotic strains; it relies on dried yeast fermentation products and the natural bacterial ecosystem of the ingredients. For digestive-support-focused owners, the Stella approach is explicit. Shop on Amazon →
Where Primal Pronto holds its own
Whole-food supplementation philosophy: Primal replaces much of the conventional synthetic vitamin tail with whole-food sources — dried yeast for B-vitamins, kelp for iodine and trace minerals, alfalfa for vitamin K and additional micronutrients, cod liver oil for vitamin A and D. Only vitamin E and taurine are added as discrete supplements. For owners who prefer a whole-food approach over proteinate-form supplementation, Primal is the cleaner fit.
Broader organic produce layer: Ten organic fruit and vegetable ingredients (squash, carrots, kale, apples, parsley, pumpkin seeds, sunflower seeds, blueberries, cranberries, broccoli) vs. Stella’s seven. The wider plant matrix delivers a broader phytonutrient profile and more diversified soluble and insoluble fiber.
Grass-fed protein signaling: Primal emphasizes antibiotic- and steroid-free beef sourcing in its marketing and product pages, and the grass-fed positioning for ruminant proteins is explicit. Stella’s cage-free claim on poultry is comparable but differently framed. Shop on Amazon →
The bottom line
This is a tie on measurable rubric-scored ingredient quality — both A/90 with documented HPP pathogen control, which is the theoretical ceiling for raw-format products in our current rubric. The decision is practical: for shelf-stable pantry feeding plus probiotic density, Stella & Chewy’s Freeze-Dried Raw. For whole-food supplementation purism and the widest organic produce layer, Primal Pronto Frozen Raw. For households that need to avoid raw-format pathogen risk entirely, step laterally to The Farmer’s Dog (A/90) or JustFoodForDogs (A/90) cooked-fresh alternatives.
