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 | 24 | 26.5 (band 18 to 40%) | 93.2 |
| Fat | 14 | 15.5 (band 5.5 to 20%) | 100 |
| Fibre | 3 | 3.3 (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: 13 nutritional additives on the label
- Vitamin A (retinyl acetate) 16,925 IU
- Vitamin D3 (cholecalciferol) 2,115 IU
- Vitamin E (α-tocopherol) 655 mg

- Sodium Selenite 0.23 mg (Total Selenium 0.1 mg)
- L-Carnitine 60 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 (78% of the recipe mass) (voluntary) | 15.6/20 |
| 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) | 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 (Analytical constituents declared, Batch and date labelling).
Safety: recall history

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
- "Complete and balanced to support long-term health and performance" — supported by the declared complete and balanced data.
6 further claims on file that we cannot check against the label.
Moderate: every checkable claim is consistent with the declared label.
