Recipe: how the 1-100 score is calculated
Why this score?
This recipe achieves an overall score of 66 out of 100 based on several key factors. The overall quality of the ingredient list adds +7.7 points, and the meat content contributes +3.3 points to the total. However, the processing format reduces the score by -6.7 points, and ingredients without printed percentages deducts -4.2 points.
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 | 26 | 28.7 (band 18 to 40%) | 99.3 |
| Fat | 10 | 11 (band 5.5 to 20%) | 93 |
| Fibre | 4 | 4.4 (band 0.5 to 5%) | 100 |
Scored over 3 declared nutrients (combined weight 50); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.
Declared fortification: 3 nutritional additives on the label
- Vitamin A 30,000 iu/kg
- Vitamin D3 3,000 iu/kg
- Vitamin E 125 mg/kg
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 (60.1% of the recipe mass) (voluntary) | 12/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) | 5/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) | 10/10 |
| Manufacturer identity and address (mandatory) | 10/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |
Capped at 60: mandatory items missing (Analytical constituents 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 — 2 checkable claims: 2 consistent, 0 contradicted.
Consistent with the label
- "complete hypoallergenic food for adult dogs with special dietary requirements" — supported by the declared complete and balanced data.
