Who is this food for?
Suits
- Labelled by the manufacturer for adult dogs
- Doesn't list chicken, beef, turkey, lamb, venison, pork, duck as ingredients

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 | 25 | 27.6 (band 18 to 40%) | 96.2 |
| Fat | 10 | 11 (band 5.5 to 20%) | 93 |
| Fibre | 2 | 2.2 (band 0.5 to 5%) | 92.8 |
Scored over 3 declared nutrients (combined weight 50); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.
Declared fortification: 13 nutritional additives on the label
- Vitamin A 11,000 IU/kg
- Vitamin D3 1,200 IU/kg
- Vitamin E 125 IU/kg
- Copper (as Cupric Sulphate) 25 mg/kg
- Vitamin B1
- Vitamin B2
- Vitamin B6
- Vitamin B12
- Biotin
- Folic Acid
- Nicotinic Acid (Niacin)
- Pantothenic Acid (Calcium Pantothenate)
- Deodorase (Yucca plant extract)
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) - 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 |

Evidence: what the brand claims, and what supports it
The claims made on the pack and product page, checked against the declared label. We record claims as stated; "consistent" means our stored label data supports the claim, "contradicted" means it conflicts with it. Functional claims are recorded but never scored.
50/100 · limited — 2 checkable claims: 1 consistent, 1 contradicted.
Contradicted by the label
- "High in Protein" — the declared label says otherwise on high protein.
Consistent with the label
- "Complete and balanced food. It contains everything your dog needs and requires no additional supplements" — supported by the declared complete and balanced data.
7 further claims on file that we cannot check against the label.
Limited: at least one claim contradicts the declared label, or a recent upheld ASA ruling applies.
