Who is this food for?
Suits
- Labelled by the manufacturer for adult dogs
- Labelling or feeding guide is aimed at small dogs
- Doesn't list beef, lamb, fish, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken oil and fat
- Your dog avoids turkey: the label lists dehydrated turkey protein
- Your dog avoids grain: the label lists rice - brown / whole grain
- 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.

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 | 21 | 23.3 (band 18 to 40%) | 84.5 |
| Fat | 8 | 8.9 (band 5.5 to 20%) | 84 |
| Fibre | 2.4 | 2.7 (band 0.5 to 5%) | 98.9 |
Scored over 3 declared nutrients (combined weight 50); undeclared nutrients do not affect the score.
Declared fortification: 11 nutritional additives on the label
- Vitamins 21,750 iu
- Vitamin D3 1,875 iu
- Vitamin E (Alpha Tocopherol) 233 iu
- Copper Sulphate Pentahydrate 28.0 mg
- Sodium Selenite 0.3 mg
- Iron Sulphate Monohydrate 229.2 mg
- Manganese Oxide 65.0 mg
- Zinc Oxide 91.0 mg
- Zinc Chelate of Amino Acid Hydrate 187.5 mg
- Calcium Iodate Anhydrous 2.4 mg
- 3.2.3 L-Lysine Monohydrochlorid 1,630mg
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 (21% of the recipe mass) (voluntary) | 4.2/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 10/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| 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 |
