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 | 13.5 | 44.4 (band 18 to 40%) | 100 |
| Fat | 12.95 | 42.6 (band 5.5 to 20%) | 100 |
| Fibre | 0.3 | 1 (band 0.5 to 5%) | 76.5 |
| Calcium | 0.7 | 2.3 (band 0.5 to 2.5%) | 100 |
| Phosphorus | 0.47 | 1.5 (band 0.4 to 1.6%) | 100 |
| Calcium:phosphorus ratio | 1.5 | 1.5 (band 1 to 2%) | 99.4 |
Scored over 6 declared nutrients (combined weight 80); undeclared nutrients do not affect the score.
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 (80% of the recipe mass) (voluntary) | 16/20 |
| 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).

Evidence: what the brand claims, and what supports it
The marketing claims made on the pack and product page, and how much evidence sits behind them. We record the claims as stated; we do not assess whether they are true.
| Claim | Type | Substantiation |
|---|---|---|
| delicious complete recipe (on pack) | Functional | Manufacturer assertion |
| a great starter for dogs embarking on a raw diet journey for the first time (on page) | Functional | Manufacturer assertion |
| Free from grain, fillers and low-quality ingredients (on pack) | Free-from | Manufacturer assertion |
| made with great care using only 100% British human-grade Chicken (on pack) | Content | Manufacturer assertion |
Limited: at least one claim rests on manufacturer assertion alone.
