Our verdict
Is Nulo Organic Ancient Grains Duck, Turkey & Guinea Fowl Recipe a good dog food?
We score it 48/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Complete extruded dry food for dogs of all life stages, with duck, turkey and dehydrated turkey protein as the main ingredients.
Only part of the analytical constituents are declared, so the nutritional picture is incomplete.
100% of this recipe has no printed percentage. Estimated shares are model estimates, not label facts.
Who is this food for?
Suits
- Labelled by the manufacturer for all lifestages
- Labelling or feeding guide is aimed at medium dogs
- Doesn't list beef, lamb, venison, pork as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists dried chicken protein
- Your dog avoids turkey: the label lists turkey
- Your dog avoids fish: the label lists salmon protein
- Your dog avoids duck: the label lists duck
- Your dog avoids grain: the label lists oats
- You want a single-protein recipe: this one lists more than one animal protein
- You are limiting fat: 20.0% on a dry-matter basis is in the high band
These points are derived from declared ingredients and analysis, not a substitute for veterinary advice. If your dog has a diagnosed condition, food choice is a medical nutrition decision: speak to your vet. Find foods that fit your dog.

Score history across model versions
The score shown above is always computed with the latest published model. Earlier scores are kept for the record and are never edited or deleted; a scoring change ships as a new model version with a public write-up on the methodology page.
Nutritional: declared analysis vs reference ranges
How the declared analysis compares with FEDIAF reference ranges for adult dogs. The label prints as-fed values; we convert to a dry-matter basis before scoring, and the bands are dry-matter ranges. Scores rise to 100 at the band midpoint: the reference is adequacy, not maximisation. Nutrients with a published upper limit taper again above it; fat is policed through calorie density rather than a direct penalty.
Guaranteed-analysis FEDIAF score: crude minimums and maximums are bounds, not typical values; moisture (a maximum) uses the processing median where available; experimental US score.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 35 | 38.7 (band 18 to 40%) | 100 |
| Fat | 18 | 19.9 (band 5.5 to 20%) | 100 |
| Fibre | 4.5 | 5 (band 0.5 to 5%) | 100 |
| Calcium | 1.2 | 1.3 (band 0.5 to 2.5%) | 94.8 |
| Phosphorus | 1 | 1.1 (band 0.4 to 1.6%) | 100 |
| Calcium:phosphorus ratio | 1.2 | 1.2 (band 1 to 2%) | 82 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
Omega fatty acids (omega-6 and omega-3): scored as the mean of its declared components (omega-6 100). The FEDIAF minimum for omega-6 is linoleic acid specifically.
Scored over 7 declared nutrients (combined weight 90); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.
Declared fortification: 7 nutritional additives on the label
- Methionine 0.35 %
- Vitamin E 150 IU/kg
- Niacin 160 mg/kg
- Pyridoxine (Vitamin B6) 10 mg/kg
- Taurine 0.20 %
- Ascorbic Acid (Vitamin C) 65 mg/kg
- Bacillus coagulans 80000000 CFU/lb
Low confidence: partial analysis or moisture estimated from the food type.
This measures agreement with published reference ranges, not suitability for an individual dog. For medical conditions, follow veterinary guidance.
Transparency: what the label discloses
How much the manufacturer discloses, measured against the FEDIAF Code of Good Labelling Practice and Regulation 767/2009. Mandatory items dominate the weighting.
| Item | Points |
|---|---|
| Ingredient list on the label (mandatory) | 10/10 |
| Printed percentages on the label (voluntary) - not on file | 0/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) | 5/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
