- Safety100
- EvidenceNot recorded
The Recipe score measures how attractive and transparent the declared ingredient list is. It is not, by itself, proof that the food is nutritionally appropriate for long-term feeding. The Nutritional and Evidence scores measure what we can verify towards that stronger claim.
Complete extruded dry food for adult dogs, with rice, fish oil and hydrolysed white fish as the main ingredients.
Why you might choose it
- Single named animal protein: fish.
- Declares energy content, which most labels omit.
- Nutritionally complete: formulated to be fed as the whole diet.
Why you might not
- 88% of the recipe mass has no printed percentage, so the exact split cannot be verified.

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 | 22 | 23.9 (band 19.105434782608697 to 40%) | 83.8 |
| Fat | 17 | 18.5 (band 5.837771739130435 to 20%) | 100 |
| Fibre | 2.75 | 3 (band 0.5 to 5%) | 100 |
| Calcium | 0.8 | 0.9 (band 0.5307065217391305 to 2.5%) | 80.3 |
| Phosphorus | 0.65 | 0.7 (band 0.4245652173913044 to 1.6%) | 84.4 |
| Sodium | 0.45 | 0.5 (band 0.1061413043478261+%) | 100 |
| Calcium:phosphorus ratio | 1.2 | 1.2 (band 1 to 2%) | 83.8 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 390.6 | 424.6 | 100 |
Omega fatty acids (omega-6 and omega-3): scored as the mean of its declared components (omega-6 100). The FEDIAF minimum for omega-6 is linoleic acid specifically.
Scored over 9 declared nutrients (combined weight 105); 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 (12.5% of the recipe mass) (voluntary) | 2.5/20 |
| 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) - 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 (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.

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
| Claim | Type | Check | Substantiation |
|---|---|---|---|
| Complete dietary food for adult dogs, formulated to reduce ingredient and nutrient intolerances and to support skin function in cases of dermatosis and excessive hair loss. (on page) | Functional | not checkable | Manufacturer assertion |
| This food is high in omega-3 fatty acids EPA and DHA, which have anti-inflammatory properties. (on page) | High/low level | not checkable | Manufacturer assertion |
