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.
| Model | Score | |
|---|---|---|
| v2 | 41/100 | current |
| v1 | 33/100 | |
| v1.9 | 34/100 |
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 | 19.7 | 21.4 (band 18 to 40%) | 79.3 |
| Fat | 12.9 | 14 (band 5.5 to 20%) | 100 |
| Fibre | 2.4 | 2.6 (band 0.5 to 5%) | 98.1 |
| Calcium | 0.62 | 0.7 (band 0.5 to 2.5%) | 75.2 |
| Phosphorus | 0.56 | 0.6 (band 0.4 to 1.6%) | 80.4 |
| Calcium:phosphorus ratio | 1.1 | 1.1 (band 1 to 2%) | 76.4 |
| Energy (kcal/100g) | 361 | 392.4 | 100 |
Scored over 7 declared nutrients (combined weight 90); undeclared nutrients do not affect the score.
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 (19.8% of the recipe mass) (voluntary) | 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) | 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 (Batch and date labelling).

Evidence: what the brand claims, and what supports it
The marketing claims made on the pack and product page, and how much evidence sits behind them. We record the claims as stated; we do not assess whether they are true.
| Claim | Type | Substantiation |
|---|---|---|
| EPA from fish oil helps joint cartilage healthy (on page) | Functional | Manufacturer assertion |
| Proven nutrition to support joint flexibility (on page) | Functional | Manufacturer assertion |
| Glucosamine & chondroitin are building blocks of healthy cartilage (on page) | Content | Manufacturer assertion |

| with Chicken (on pack) | Content | Manufacturer assertion |
| veterinarian recommended (on page) | Content | Manufacturer assertion |
| complete pet food for large/giant breed adult dogs from 1 year old (on pack) | Content | Manufacturer assertion |
Limited: at least one claim rests on manufacturer assertion alone.
