+Plus Adult Digestive Health Formula Dry Dog Food, 31.1-lb bag
Graded by The Sniff System
Purina ONE +Plus Adult Digestive Health Formula is a dry food for adult dogs, with chicken as its primary protein.
This formula is designed for adult maintenance, and while the exact AAFCO statement isn't published, it's inferred to meet those nutritional standards. Chicken is the first ingredient, providing a good protein start.
A key thing to watch is the lack of a declared omega-3 source. Ingredients like fish oil, salmon oil, or algae oil, which provide these beneficial fatty acids, are absent from the list.
Good fit for adult dogs looking for a chicken-based dry food. Less ideal if you prioritize a declared omega-3 source.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for active large sporting breeds, including the Golden Retriever, navigating diet-associated DCM concerns. Chicken anchors position 1, with zero pulses in the top 15. In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022 (FDA, 2022) .

Sniff scored this formula 50/100, landing in C-tier (acceptable-with-notes). The biggest contributor was AAFCO compliance (+4 points): AAFCO formulation inferred from declared adult maintenance. Verbatim statement not published by retailer. The biggest detractor was fat quality (-8 points): No declared omega-3 source. Fish oil, salmon oil, and algae oil all absent. To reach B-tier, this formula would need to gain about 10 points, most likely through fat quality.

Read why each ingredient is good or bad for dogs.
- 1protein animalchicken
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 2: major carbohydrate source.
- 3grainwhole grain corn
Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.
Position 3: major carbohydrate source.
- 4protein plantcorn gluten meal
Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.
Position 4: plant protein in the top 5. Stacked with animal protein, can inflate the crude protein number without matching the amino-acid quality of named animal sources.
- 5grainwheat
Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6beef fat preserved with mixed-tocopherols
Real animal fat from a named species, with natural vitamin E doing the preservation. The clean version.
Position 6: supporting protein. Modest contribution to total protein weight.
- 7protein animalchicken by-product meal
Ground organs, bone, and tissue. Nutritionally dense, especially the liver and gizzard fractions. Named species ('chicken') is what matters. Generic 'poultry by-product meal' is the one to worry about. See why →
Position 7: supporting protein. Modest contribution to total protein weight.
- 8protein plantsoybean meal
Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.
Position 8: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 9oat meal
Alternate spelling of oatmeal. Gentle whole grain, steady carb energy, soluble fiber.
- 10othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 11glycerin
Humectant used in soft-moist foods to keep them chewy. Safe in moderation but a signal of a processed semi-moist product.
- 12mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 13mono and dicalcium phosphate
Source of calcium and phosphorus. Standard inclusion in complete dog foods.
- 14mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 15vegetablecarrots
Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.
Position 15: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 16dried peas
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 →
- 17vegetable juice
- 18mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 19mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 20mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 21mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 22mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 23mineralcalcium iodate
Source of iodine for thyroid function. Functional, required in complete formulas.
- 24mineralsodium selenite Flagged
Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →
- 25supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
