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 | 68/100 | current |
| v1 | 67/100 |
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 | 28 | 30.4 (band 18 to 40%) | 100 |
| Fat | 16 | 17.4 (band 5.5 to 20%) | 100 |
| Fibre | 3.2 | 3.5 (band 0.5 to 5%) | 100 |
| Energy (kcal/100g) | 372 | 404.3 | 100 |
Scored over 4 declared nutrients (combined weight 60); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 8% from the food type.
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) | 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 (Analytical constituents declared, Batch and date labelling).
Safety: recall history
Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.
No recalls recorded in our database.

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 |
|---|---|---|
| rich in Iron with an easy to digest source of protein (on page) | Functional | Manufacturer assertion |
| Contains Glucosamine & Chondroitin to help with joint health (on page) | Functional | Manufacturer assertion |
| Contains Prebiotic MOS & Prebiotic FOS to help maintain a healthy gut (on page) | Functional | Manufacturer assertion |
| grain free recipe (on page) | Content | Manufacturer assertion |
| 44% TOTAL DUCK (on page) | Content | Manufacturer assertion |
| no added artificial colours, flavourings or preservatives (on page) | Free-from | Manufacturer assertion |
Limited: at least one claim rests on manufacturer assertion alone.
