51% 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 puppies
- Labelling or feeding guide is aimed at large dogs
- Doesn't list beef, lamb, 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 fish: the label lists fish oil
- 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?
The overall score reached 56 out of 100. The processing format contributed -6.7 points, and ingredients without printed percentages cost a further -5.4 points. On the positive side, the overall quality of the ingredient list added +4.3 points, with being labelled nutritionally complete contributing +2.3.
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 puppies and growth. 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.
Scored against FEDIAF growth minima; puppy scoring is under review.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 29.2 | 31.7 | 100 |
| Fat | 14.4 | 15.7 | 100 |
| Calcium | 1.09 | 1.2 | 100 |
| Phosphorus | 0.95 | 1 | 100 |
| Sodium | 0.48 | 0.5 (band 0.2361413043478261+%) | 100 |
| Calcium:phosphorus ratio | 1.1 | 1.1 | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 395 | 429.3 | 100 |
Omega fatty acids (omega-6 and omega-3): scored as the mean of its declared components (omega-6 100, omega-3 100). The FEDIAF minimum for omega-6 is linoleic acid specifically.
Scored over 8 declared nutrients (combined weight 95); undeclared nutrients do not affect the score.
Declared fortification: 7 nutritional additives on the label
- 3b103 (Iron) 82.2mg
- 3b202 (Iodine) 2.9mg
- 3b405 (Copper) 8.9mg

- 3b603 (Zinc) 135mg
- 3b801 (Selenium) 0.1mg
- with natural antioxidant
High confidence: full analysis plus minerals or omegas and declared energy.
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 (49.3% of the recipe mass) (voluntary) | 9.9/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 5/10 |
| Energy value declared (voluntary) | 5/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) | 10/10 |
| Manufacturer identity and address (mandatory) | 10/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |
Capped at 60: mandatory items missing (Batch and date labelling).

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.
100/100 · moderate — 2 checkable claims: 2 consistent, 0 contradicted.
Consistent with the label
- "High-quality protein for building lean muscles" — supported by the declared high protein data.
- "complete pet food, specially formulated with ActivBiome+ Multi-Benefit Technology" — supported by the declared complete and balanced data.
5 further claims on file that we cannot check against the label.
Moderate: every checkable claim is consistent with the declared label.
