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 | 28.3 (band 18 to 40%) | 98 |
| Fat | 13 | 14.1 (band 5.5 to 20%) | 100 |
| Fibre | 3 | 3.3 (band 0.5 to 5%) | 100 |
| Calcium | 2 | 2.2 (band 0.5 to 2.5%) | 100 |
| Phosphorus | 1.2 | 1.3 (band 0.4 to 1.6%) | 100 |
| Calcium:phosphorus ratio | 1.7 | 1.7 (band 1 to 2%) | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 361 | 392.4 | 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: 3 nutritional additives on the label
- Vitamin A 15,000 IU
- Vitamin D3 2,000 IU
- Vitamin E 95 IU
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 (82% of the recipe mass) (voluntary) | 16.4/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 10/10 |
| 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 |
