Who is this food for?
Suits
- Labelled by the manufacturer for senior dogs
- Labelling or feeding guide is aimed at medium dogs
- Doesn't list chicken, beef, turkey, venison, duck as ingredients
Consider something else if:
- Your dog avoids lamb: the label lists lamb
- Your dog avoids fish: the label lists hydrolyzed crustacean shells
- Your dog avoids pork: it is listed as an ingredient
- Your dog avoids grain: the label lists maize / corn
- You want a single-protein recipe: this one lists more than one animal protein
- You need more protein than this: 18.7% 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?
This recipe achieves an overall score of 40 out of 100. Being labelled nutritionally complete adds +2.3 points to the total. However, ingredients without printed percentages deducts -8.4, the processing format takes away -6.7, and the carbohydrate content reduces the score by -4.2.
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 | 17.2 | 18.7 (band 18 to 40%) | 71.9 |
| Fat | 13.5 | 14.7 (band 5.5 to 20%) | 100 |
| Fibre | 2.2 | 2.4 (band 0.5 to 5%) | 95.2 |
| Calcium | 0.73 | 0.8 (band 0.5 to 2.5%) | 78.8 |
| Phosphorus | 0.6 | 0.7 (band 0.4 to 1.6%) | 82.6 |
| Sodium | 0.24 | 0.3 (band 0.1+%) | 100 |
| Calcium:phosphorus ratio | 1.2 | 1.2 (band 1 to 2%) | 83 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 363 | 394.6 | 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.

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 (20% of the recipe mass) (voluntary) | 4/20 |
| 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) | 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 |
