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 cold-pressed dry food for dogs of all life stages, with trout, sweet potatoes and goose as the main ingredients.
Why you might choose it
- Doesn't list grain ingredients.
- High in protein: 55% protein on a dry-matter basis.
Why you might not
- 100% of the recipe mass has no printed percentage, so the exact split cannot be verified.

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 | 51.2 | 55.2 (band 18 to 40%) | 100 |
| Fat | 17.9 | 19.3 (band 5.5 to 20%) | 100 |
| Fibre | 2.4 | 2.6 (band 0.5 to 5%) | 97.9 |
| Calcium | 1.1 | 1.2 (band 0.5 to 2.5%) | 90.6 |
| Phosphorus | 0.7 | 0.8 (band 0.4 to 1.6%) | 87.8 |
| Calcium:phosphorus ratio | 1.6 | 1.6 (band 1 to 2%) | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 69.8 |
| Energy (kcal/100g) | 390 | 420.7 | 100 |
Omega fatty acids (omega-6 and omega-3): scored as the mean of its declared components (omega-6 69.8). The FEDIAF minimum for omega-6 is linoleic acid specifically.
Scored over 8 declared nutrients (combined weight 100); 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 (0.3% of the recipe mass) (voluntary) | 0.1/20 |
| 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) | 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 (Batch and date labelling).
