NutrientBoost Lamb, Brown Rice & Pearled Barley Gut Health Whole Grain Dry Dog Food for Medium & Large Dogs, 22-lb bag
Graded by The Sniff System
Solid Gold NutrientBoost Lamb, Brown Rice & Pearled Barley is a dry dog food featuring lamb as its primary protein source.
This formula offers reasonable protein quality, with lamb providing solid amino acid coverage. It also includes quality fat sources, like named fats and marine oil for EPA and DHA, alongside good carbohydrate sources that provide fermentable fiber.
The main thing to note is the absence of an AAFCO statement, which means the nutritional completeness of this food is unverified. This factor capped its overall score.
Good fit for medium and large dogs. Less ideal if you prefer a food with a verified AAFCO statement for nutritional completeness.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Frenchies have notoriously sensitive GI tracts plus a tendency toward obesity given their low activity needs. Limited-ingredient formulas with moderate calorie density tend to fit them well. Strong fit for adult French Bulldogs and similar lower-energy companion breeds navigating a sensitive stomach. Lamb leads at position 1, and a single-species protein design that makes trigger isolation easier.

At 59/100, this formula lands mid-pack. The lift comes from protein quality, worth 15 points to the final number: Reasonable protein quality. lamb 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.
Reasonable protein quality. lamb delivers solid amino acid coverage.
Quality fat sources: named fat with marine oil (EPA and DHA source).
Quality carbohydrate sources with fermentable fiber.
No AAFCO statement. Nutritional completeness unverified.

- 1protein animallamb
Real meat. Often used for dogs with chicken or beef sensitivities. Slightly higher fat content than chicken.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animallamb meal
Lamb cooked down to a dry concentrate. Per pound, more protein than fresh lamb. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 3: major carbohydrate source.
- 4grainpearled barley
Barley with the outer hull removed. Easy to digest, steady carb release.
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5grainoatmeal
Gentle on the stomach. Slow-release carbs and soluble fiber that supports stool quality.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6legumepeas
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 6. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 7grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 7: supporting grain. Smaller contribution to the carb deck.
- 8legumechickpeas
Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →

Position 10: supporting protein. Modest contribution to total protein weight.
- 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
- 14fatground flaxseed
Cracked flaxseed for better digestibility. Same plant omega-3s as whole flaxseed, just easier for the dog to extract.
Position 14: trace fat. Below the level that materially shifts the fat profile.
- 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.
- 16vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
- 17fatsalmon oil
Pure omega-3s. The thing skin-and-coat formulas are usually built around.
- 18mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 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.
- 21supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 22supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 23mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 24mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 25mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
