Original Ultra Chicken Formula Dry Dog Food, 24-lb bag
Graded by The Sniff System
Natural Balance Original Ultra Chicken Formula Dry Dog Food is a dry kibble that features chicken as its main protein source.
This formula offers reasonable protein quality, with chicken providing solid amino acid coverage. It also includes quality carbohydrate sources that provide fermentable fiber, and good fat sources like named chicken fat and marine oil for EPA and DHA.
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 adult dogs. Less ideal if you prefer a food with a verified AAFCO statement.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for adult Labrador Retrievers and similar active sporting breeds navigating weight management. At 390 kcal/cup this formula runs on the moderate side, with crude fiber at 5% (above the catalog median, supports satiety). 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. 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) .

Sniff scored this formula 59/100, landing in C-tier (acceptable-with-notes). The biggest contributor was protein quality (+18.5 points): Reasonable protein quality. chicken delivers solid amino acid coverage. A hard cap of 59 also applied 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). If the brand publishing the AAFCO statement were on the label, the cap would lift and this formula could clear the B-band threshold (60).

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.
- 3grainpearled barley
Barley with the outer hull removed. Easy to digest, steady carb release.
Position 3: major carbohydrate source.
- 4legumepeas
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 4. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 5oat groats
Whole oats with only the inedible hull removed. The most intact form of oats available.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7dried plain beet pulp
Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality. See why →
Position 7: functional fiber for digestion or satiety.
- 8othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 9grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 9: minor grain inclusion.
- 10mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 11fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12dried vegetable broth
- 13fatmenhaden fish oil
Omega-3 from menhaden, a small oily fish. Same skin and coat support as salmon oil.
Position 13. Trace marine oil. Contributes some omega-3 but well below the level that drives EPA/DHA totals.
- 14vegetablecarrots
Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.
Position 14: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 15supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 16mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 17mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 18supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 19vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 20vitaminascorbic acid
Vitamin C. Pulls double duty as a natural antioxidant preservative.
- 21vitaminniacin supplement
B vitamin (B3). Required in complete dog foods, added as a supplement to standardize the dose.
- 22vitaminvitamin a supplement
Vitamin A in stable, standardized form. Required for vision, immune function, and growth.
- 23vitaminthiamine mononitrate
B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.
- 24vitamind-calcium pantothenate
B vitamin (B5). Standard inclusion in complete dog foods.
- 25vitaminriboflavin supplement
B vitamin (B2). Required in complete dog foods. The standardized form ensures consistent dosing.
