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 lamb, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken
- Your dog avoids beef: the label lists beef fat
- Your dog avoids turkey: the label lists poultry
- Your dog avoids fish: the label lists fish meal
- 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.

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 | 26 | 28.7 (band 18.994475138121548 to 40%) | 97.8 |
| Fat | 12 | 13.3 (band 5.803867403314918 to 20%) | 100 |
| Fibre | 4.5 | 5 (band 0.5 to 5%) | 100 |
| Calcium | 1 | 1.1 (band 0.5276243093922652 to 2.5%) | 87.6 |
| Phosphorus | 0.8 | 0.9 (band 0.42209944751381223 to 1.6%) | 93.5 |
| Calcium:phosphorus ratio | 1.3 | 1.3 (band 1 to 2%) | 85 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 382 | 422.1 | 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 8 declared nutrients (combined weight 100); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.
No nutritional additives section declared on the label.
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) - not on file | 0/10 |
| Energy value declared (voluntary) | 5/5 |

Safety: recall history
Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.
No recalls recorded in our database.
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 protein promotes muscle conditioning when combined with proper exercise" — the declared label says otherwise on high protein.
Consistent with the label
- "100% complete and balanced nutrition for adult dogs" — supported by the declared complete and balanced data.
6 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.
