Recipe: how the 1-100 score is calculated
Why this score?
This recipe achieves an overall score of 54 out of 100 based on several key factors. The overall quality of the ingredient list positively influences the result by contributing +7 points. However, the processing format detracts from the total with a change of -6.7. Similarly, the carbohydrate content impacts the score by -4.8, and ingredients without printed percentages further adjust the final result by -4.2.
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 | 25 | 27.5 (band 18 to 40%) | 95.8 |
| Fat | 12.5 | 13.7 (band 5.5 to 20%) | 100 |
| Fibre | 4.5 | 4.9 (band 0.5 to 5%) | 100 |
| Calcium | 0.9 | 1 (band 0.5 to 2.5%) | 84.7 |
| Phosphorus | 0.7 | 0.8 (band 0.4 to 1.6%) | 88.5 |
| Calcium:phosphorus ratio | 1.3 | 1.3 (band 1 to 2%) | 87.1 |
| 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.

Medium confidence: the full five-part analysis is on file; where moisture was not declared it was 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 (60.2% of the recipe mass) (voluntary) | 12/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 10/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) - not on file | 0/10 |
| Manufacturer identity and address (mandatory) | 10/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |
