Recipe: how the 1-100 score is calculated
Why this score?
The overall quality of the ingredient list contributed +9.2 points, and the meat content added a further +6.3 points. Pulling the score down, the carbohydrate content subtracted -0.9 points, while the oil and fat content accounted for -0.2 points. Taken together, these factors produce a final score of 93 out of 100.
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 | 12.8 | 49.4 (band 21.544401544401538 to 40%) | 100 |
| Fat | 6.2 | 23.9 (band 6.583011583011581 to 20%) | 100 |
| Fibre | 1 | 3.9 (band 0.5 to 5%) | 100 |
| Calcium | 2.2 | 8.5 (band 0.5984555984555983 to 2.5%) | 0 |
| Phosphorus | 1.76 | 6.8 (band 0.47876447876447864 to 1.6%) | 0 |
| Calcium:phosphorus ratio | 1.3 | 1.3 (band 1 to 2%) | 85 |
| Energy (kcal/100g) | 124 | 478.8 | 100 |
Scored over 7 declared nutrients (combined weight 90); undeclared nutrients do not affect the score.
No nutritional additives section declared on the label.
High confidence: full analysis plus minerals or omegas and declared energy.
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 (100% of the recipe mass) (voluntary) | 20/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) - not on file | 0/10 |
| Energy value declared (voluntary) | 5/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) | 10/10 |
| Manufacturer identity and address (mandatory) | 5/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |
Capped at 60: mandatory items missing (Additives declared, Batch and date labelling).

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.
100/100 · moderate — 1 checkable claim: 1 consistent, 0 contradicted.
Consistent with the label
- "Single Protein" — supported by the declared single protein data.
8 further claims on file that we cannot check against the label.
Moderate: every checkable claim is consistent with the declared label.
