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 beef, turkey, lamb, fish, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken oil and fat
- Your dog avoids grain: the label lists maize / corn
- You are limiting fat: 21.7% on a dry-matter basis is in the high 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?
This recipe achieves a final score of 45 out of 100 based on several key factors. The overall quality of the ingredient list added +5.3 points. However, ingredients without printed percentages reduced the score by -10.6. Additionally, the processing format deducted -6.7 and the carbohydrate content contributed -2.8.
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 | 30 | 32.6 (band 18 to 40%) | 100 |
| Fat | 20 | 21.7 (band 5.5 to 20%) | 100 |
| Fibre | 2.5 | 2.7 (band 0.5 to 5%) | 99.6 |
Scored over 3 declared nutrients (combined weight 50); undeclared nutrients do not affect the score.
No nutritional additives section declared on the label.
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) - not on file | 0/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) - not on file | 0/10 |
| 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 (Additives declared, Feeding guidance given, 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.
See all current recalls we track.
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.
50/100 · limited — 2 checkable claims: 1 consistent, 1 contradicted.
Contradicted by the label
- "WHEAT-FREE RECIPE" — the declared label says otherwise on grain-free.
Consistent with the label
- "Higher in protein & fat for endurance and stamina" — supported by the declared high protein data.
4 further claims on file that we cannot check against the label.
Limited: at least one claim contradicts the declared label, or a recent upheld ASA ruling applies.
| Claim | Type | Check | Substantiation |
|---|---|---|---|
| JOINT SUPPORT (on page) | Functional | not checkable | Manufacturer assertion |
| DIGESTIVE SUPPORT (on page) | Functional | not checkable | Manufacturer assertion |
| HEART SUPPORT (on page) | Functional | not checkable | Manufacturer assertion |
| SKIN AND COAT SUPPORT (on page) | Functional | not checkable | Manufacturer assertion |
| Higher in protein & fat for endurance and stamina (on page) | High/low level | consistent | Manufacturer assertion |
| WHEAT-FREE RECIPE (on page) | Free-from | contradicted | Manufacturer assertion |
