100% of this recipe has no printed percentage. Estimated shares are model estimates, not label facts.
Who is this food for?
Suits
- Labelled by the manufacturer for adult dogs
- Labelling or feeding guide is aimed at large dogs
- Doesn't list beef, turkey, lamb, venison, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken
- Your dog avoids fish: the label lists fish oil
- Your dog avoids pork: it is listed as an ingredient
- Your dog avoids grain: the label lists pearled barley
- 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 +3.6 points to the total. However, the presence of ingredients without printed percentages reduced the score by -10.6. Furthermore, the processing format decreased the score by -6.7, and the carbohydrate content lowered the final result by -3.8.
Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

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.
Guaranteed-analysis FEDIAF score: crude minimums and maximums are bounds, not typical values; moisture (a maximum) uses the processing median where available; experimental US score.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 25.1 | 27.7 (band 18 to 40%) | 96.5 |
| Fat | 14.3 | 15.8 (band 5.5 to 20%) | 100 |
| Fibre | 2.1 | 2.3 (band 0.5 to 5%) | 94.3 |
| Calcium | 0.95 | 1 (band 0.5 to 2.5%) | 86.5 |
| Phosphorus | 0.75 | 0.8 (band 0.4 to 1.6%) | 91.4 |
| Sodium | 0.37 | 0.4 (band 0.1+%) | 100 |
| Calcium:phosphorus ratio | 1.3 | 1.3 (band 1 to 2%) | 86 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 361 | 398.9 | 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. Moisture was not declared and was estimated at 9.5% from the food type.

Low confidence: partial analysis or moisture 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 (voluntary) - not on file | 0/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| 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) | 5/10 |
