NutrientBoost Chicken & Sweet Potato Weight Control Gut Health Grain-Free Dry Dog Food for Medium & Large Dogs, 22-lb bag
Graded by The Sniff System
Solid Gold NutrientBoost Chicken & Sweet Potato Weight Control Gut Health is a dry dog food focused on chicken as its main protein, designed for weight management.
The protein quality is good, with chicken providing solid amino acid coverage. It uses quality fat sources, including marine oil for beneficial EPA and DHA. The ingredient stacking is strong, pairing fresh chicken with chicken meal.
This product lacks an AAFCO statement, so its nutritional completeness is unverified. There's also high legume stacking with multiple pea ingredients in the top 15, though animal plasma in the top 10 might offer some mitigation.
Good fit for medium and large dogs needing weight control. Less ideal if you prefer foods with a verified AAFCO statement.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for adult Labrador Retrievers navigating weight management. Working in its favor: crude fiber (10%) helps satiety. At 320 kcal/cup this formula runs on the lean side, with crude fiber at 10% (above the catalog median, supports satiety), and the product name signals a weight-management design. 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. According to the Association for Pet Obesity Prevention's 2023 survey, 59% of dogs in the United States were classified as overweight or obese by their veterinary healthcare professional, representing an estimated 55 million dogs (APOP, 2023) .

Middle-of-pack grade. 59/100 (C) reflects the structural fit of this formula against The Sniff System's eight scoring components. Protein quality did the heavy lifting (+18 points): Reasonable protein quality. chicken delivers solid amino acid coverage. What capped it: the score can't exceed 59 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). How it could climb: the brand publishing the AAFCO statement, which would lift the cap into B-band range.
Reasonable protein quality. chicken delivers solid amino acid coverage.
Quality fat sources: named fat with marine oil (EPA and DHA source).
Named fresh meat paired with same-species meal, a strong extrusion architecture.
No AAFCO statement. Nutritional completeness unverified.
Contains high legume stacking. Multiple pulse-family ingredients in top 15. Mitigated by taurine supplementation or organ meat (natural taurine precursor) in top 10..
- Lowest caloric density in Solid Gold's lineup (320 kcal/cup)
- Top 4% for crude fiber in grain-free dry kibbles (11.1% DMB)
- Bottom 3% for DMB fat in Solid Gold's lineup (7.2%)

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.
- 2protein animalchicken meal
Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3vegetablesweet potato
Complex carb with fiber and beta-carotene. Gentle on the stomach.
Position 3: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 4vegetablepotato
Standard white potato. Steady carb source, common starch in grain-free recipes.
Position 4: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 5legumepeas
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 5. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 6protein plantpea protein
Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.
Position 6. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 7fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 7. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 8pea starch
Refined starch from peas, mostly carbs after the protein is removed. Counts toward the legume stack the FDA examined.
Position 8. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 9protein animalocean fish meal
Position 9: supporting protein. Modest contribution to total protein weight.
- 10animal plasma
- 11fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 13spray dried animal blood cells
- 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.
- 16mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 17vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
- 18green beans
Real vegetable. Fiber and a small amount of vitamins. Often used in weight-management formulas because it bulks up a meal without adding calories.
- 19fruitblueberries
Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.
- 20fruitcranberries
Often added with a urinary-tract-support marketing angle. Real cranberry compounds help in concentrate form, but kibble doses are small.
- 21supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 22supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 23fatsalmon oil
Pure omega-3s. The thing skin-and-coat formulas are usually built around.
- 24mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 25mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
