Complete wet paté food for adult dogs, with kidney, oat bran and fructo as the main ingredients.
Declared analysis sits below the FEDIAF minimum for protein, phosphorus.
100% of this recipe has no printed percentage. Estimated shares are model estimates, not label facts.
Who is this food for?
Suits
- Labelled by the manufacturer for adult dogs
- Doesn't list chicken, beef, turkey, lamb, fish, venison, duck as ingredients
Consider something else if:
- Your dog avoids pork: the label lists pork liver
- Your dog avoids grain: the label lists oat bran
- You are limiting fat: 25.2% on a dry-matter basis is in the high band
- You need more protein than this: 15.6% on a dry-matter basis is in the low band
These points are derived from declared ingredients and analysis, not a substitute for veterinary advice. If your dog has a diagnosed condition, food choice is a medical nutrition decision: speak to your vet. Find foods that fit your dog.

Recipe: how the 1-100 score is calculated
Why this score?
The overall score reaches 41 out of 100. Undeclared ingredient shares, meaning ingredients without printed percentages, contributed -10.6. The remaining ingredients contributed -3.2, lower-quality ingredients added -2.8, and the additive load contributed -2.8. This is a general explanation of how the score works, not veterinary advice. For any health condition, food choice is a decision for your vet.
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 | 4.2 | 15.6 (band 20.216666666666665 to 40%) | 53.9 |
| Fat | 6.8 | 25.2 (band 6.177314814814814 to 20%) | 100 |
| Fibre | 0.5 | 1.9 (band 0.5 to 5%) | 88 |
| Calcium | 0.2 | 0.7 (band 0.561574074074074 to 2.5%) | 75.5 |
| Phosphorus | 0.07 | 0.3 (band 0.44925925925925925 to 1.6%) | 40.4 |
| Sodium | 0.05 | 0.2 (band 0.11231481481481481+%) | 100 |
| Calcium:phosphorus ratio | 2.9 | 2.9 (band 1 to 2%) | 57.1 |
| Energy (kcal/100g) | 121.3 | 449.3 | 100 |
Scored over 8 declared nutrients (combined weight 95); 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 (voluntary) - not on file | 0/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 5/10 |
| 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 |

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
- "low level of phosphorus and a restricted level of protein but of high quality" — supported by the declared low protein data.
7 further claims on file that we cannot check against the label.
Moderate: every checkable claim is consistent with the declared label.
