Recipe: how the 1-100 score is calculated
Why this score?
The overall score for this food is 30 out of 100. Undeclared ingredient shares, listed as ingredients without printed percentages, contributed -10.6 points, reflecting that buyers cannot see how much of the recipe is made up by each component. Lower-quality ingredients contributed -4.7 points, and the remaining ingredients added -4.6 points, pulling the score down further. Finally, lower-quality meat ingredients contributed -3.8 points, since the meat sources used are not among the higher-quality options in our assessment.
Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

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 | 8.7 | 41.8 (band 18 to 40%) | 100 |
| Fat | 5.4 | 26 (band 5.5 to 20%) | 100 |
| Fibre | 0.8 | 3.8 (band 0.5 to 5%) | 100 |
Scored over 3 declared nutrients (combined weight 50); undeclared nutrients do not affect the score.
Declared fortification: 7 nutritional additives on the label
- Vitamin D3: 160 IU
- Vitamin C: 30 mg
- Iron (3b103): 9 mg
- Iodine (3b202): 0.23 mg
- Copper (3b405, 3b406): 1.9 mg
- Manganese (3b502, 3b503, 3b504): 2.7 mg
- Zinc (3b603, 3b605, 3b606): 27 mg
Medium confidence: the full five-part analysis is on file; where moisture was not declared it was 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 (voluntary) - not on file | 0/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 10/10 |
| 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) | 5/5 |
Safety: recall history
Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.

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.
Claims on file; none we can check against the label

|---|---|---|---|
| Helps support digestive health with highly digestible proteins and a balanced supply of fibres. (on page) | Functional | not checkable | Manufacturer assertion |
| Helps support large dogs' healthy bones and joints through a combination of minerals and nutrients. (on page) | Functional | not checkable | Manufacturer assertion |
