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 | 27.2 (band 18 to 40%) | 95 |
| Fat | 8 | 8.7 (band 5.5 to 20%) | 83.2 |
| Fibre | 3.5 | 3.8 (band 0.5 to 5%) | 100 |
| Calcium | 1 | 1.1 (band 0.5 to 2.5%) | 87.6 |
| Phosphorus | 0.9 | 1 (band 0.4 to 1.6%) | 98.9 |
| Calcium:phosphorus ratio | 1.1 | 1.1 (band 1 to 2%) | 76.7 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 340 | 369.6 | 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 8 declared nutrients (combined weight 100); undeclared nutrients do not affect the score.
Declared fortification: 9 nutritional additives on the label
- Vitamin A 15,000 IU
- Vitamin D3 2,000 IU
- Vitamin E 95 IU
- L-Carnitine 480mg

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.
