Who is this food for?
Suits
- Labelled by the manufacturer for adult dogs
- Labelling or feeding guide is aimed at medium and large dogs
- Doesn't list beef, lamb, fish, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists dehydrated chicken and turkey
- Your dog avoids turkey: the label lists dehydrated chicken and turkey
- Your dog avoids grain: the label lists rice - white
- You want a single-protein recipe: this one lists more than one animal protein
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 rating of 42 out of 100 based on several key factors. The overall quality of the ingredient list contributed +2.5 points to the total. However, the presence of ingredients without printed percentages reduced the score by -7.8. Furthermore, the processing format decreased the score by -6.7, and the carbohydrate content lowered the final result by -5.3.
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 | 22.3 | 24.2 (band 18.09782608695652 to 40%) | 86.8 |
| Fat | 14 | 15.2 (band 5.529891304347825 to 20%) | 100 |
| Fibre | 1.7 | 1.8 (band 0.5 to 5%) | 88 |
| Calcium | 0.8 | 0.9 (band 0.5027173913043478 to 2.5%) | 81 |
| Phosphorus | 0.68 | 0.7 (band 0.40217391304347827 to 1.6%) | 86.9 |
| Sodium | 0.25 | 0.3 (band 0.10054347826086957+%) | 100 |
| Calcium:phosphorus ratio | 1.2 | 1.2 (band 1 to 2%) | 80.6 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 370 | 402.2 | 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.

| Ingredient list on the label (mandatory) | 10/10 |
| Printed percentages on the label (26.5% of the recipe mass) (voluntary) | 5.3/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 10/10 |
| Energy value declared (voluntary) | 5/5 |
