Field Master 30/20 High-Protein Dry Dog Food, 40-lb bag
Graded by The Sniff System
Sportsman's Pride Field Master 30/20 High-Protein Dry Dog Food is a dry formula with chicken meal as its primary protein source.
This food features chicken meal, which provides solid amino acid coverage for protein quality. It also includes quality carbohydrate sources with fermentable fiber and premium micronutrient forms like chelated minerals.
The main thing to note is the absence of an AAFCO statement. This means the nutritional completeness of the food is unverified, which capped its overall score.
Good fit for active adult dogs who need higher protein and fat. Less ideal if you prioritize verified nutritional completeness.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for lower-energy small companion breeds, including the French Bulldog, navigating a sensitive stomach. Chicken meal leads at position 1, with dried plain beet pulp (prebiotic fiber) at position 12 on the deck, and a single-species protein design that makes trigger isolation easier. 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.

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 (+14.5 points): Reasonable protein quality. chicken meal 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 meal delivers solid amino acid coverage.
Quality carbohydrate sources with fermentable fiber.
Premium micronutrient forms such as chelated minerals or natural vitamin E.
No AAFCO statement. Nutritional completeness unverified.

Read why each ingredient is good or bad for dogs.
- 1protein animalchicken meal
Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2grainbarley
Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.
Position 2: major carbohydrate source.
- 3oat groats
Whole oats with only the inedible hull removed. The most intact form of oats available.
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.
- 5fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 5: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 6
- 7grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 7: supporting grain. Smaller contribution to the carb deck.
- 8dried yeast
Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.
- 9fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 9: trace fat. Below the level that materially shifts the fat profile.
- 10othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 11dried eggs
Whole eggs. The highest-quality protein on any ingredient label by amino acid score.
Position 11: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
- 12dried 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 12: trace fiber inclusion.
- 13mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 14fatsunflower oil
Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.
Position 14: trace fat. Below the level that materially shifts the fat profile.
- 15fiberchicory root
Prebiotic fiber that supports gut bacteria. A genuine functional ingredient, not marketing.
Position 15: trace fiber inclusion.
- 16supplementyucca schidigera extract
Plant extract added to reduce stool odor. Functional, not nutritional. Fine in trace amounts.
- 17mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 18mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 19mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 20mineraliron sulfate
- 21mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 22mineraliron proteinate
Iron bound to protein for better absorption. The premium form versus inorganic iron sulfate.
- 23mineralcopper proteinate
Copper bound to protein for better absorption. Common in better-formulated diets.
- 24mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 25mineralcalcium iodate
Source of iodine for thyroid function. Functional, required in complete formulas.
