Recipe: how the 1-100 score is calculated
Why this score?
This recipe achieves a final score of 47 out of 100 based on several key factors. The overall quality of the ingredient list added +4.5 points. However, ingredients without printed percentages reduced the score by -7.4. Additionally, the processing format deducted -6.7 and the carbohydrate content contributed -3.7.
Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

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.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 19.9 | 21.6 (band 18.09782608695652 to 40%) | 79.7 |
| Fat | 14.2 | 15.4 (band 5.529891304347825 to 20%) | 100 |

| Calcium | 0.64 | 0.7 (band 0.5027173913043478 to 2.5%) | 75.8 |
| Phosphorus | 0.58 | 0.6 (band 0.40217391304347827 to 1.6%) | 81.4 |
| Sodium | 0.25 | 0.3 (band 0.10054347826086957+%) | 100 |
| Calcium:phosphorus ratio | 1.1 | 1.1 (band 1 to 2%) | 76.2 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 370 | 402.2 | 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 9 declared nutrients (combined weight 105); undeclared nutrients do not affect the score.

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.

|---|---|
| Ingredient list on the label (mandatory) | 10/10 |
| Printed percentages on the label (30% of the recipe mass) (voluntary) | 6/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 10/10 |

Evidence: what the brand claims, and what supports it
The claims made on the pack and product page, checked against the declared label. We record claims as stated; "consistent" means our stored label data supports the claim, "contradicted" means it conflicts with it. Functional claims are recorded but never scored.
50/100 · limited — 4 checkable claims: 2 consistent, 2 contradicted.
Contradicted by the label
- "Formulated with a single novel animal protein source & no grain" — the declared label says otherwise on single protein.
- "High quality Salmon as the only intact animal protein source" — the declared label says otherwise on single protein.
Consistent with the label
- "complete pet food for adult small dogs 1–6 years old" — supported by the declared complete and balanced data.
- "complete pet food for small breed dogs aged 1–6 years old" — supported by the declared complete and balanced data.
8 further claims on file that we cannot check against the label.
Limited: at least one claim contradicts the declared label, or a recent upheld ASA ruling applies.
