Our verdict
Is mera brocken Trockenfutter a good dog food?
We score it 31/100 (Poor). The main reasons are set out in "Why you might not" below, and every step of the calculation is shown under "How we calculated this score".
Complete extruded dry food for adult dogs, with cereals, meat and animal derivatives and poultry as the main ingredients.
Only part of the analytical constituents are declared, so the nutritional picture is incomplete.
99% 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
- Doesn't list beef, lamb, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists poultry
- Your dog avoids turkey: the label lists poultry
- Your dog avoids fish: the label lists salmon oil
- Your dog avoids grain: the label lists cereals
- 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 product reached an overall score of 31 out of 100. It lost points for ingredients without printed percentages, which contributed -10.4, and the processing format contributed -6.7. Lower-quality ingredients contributed -3.4, and the remaining ingredients contributed -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 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 | 23.2 (band 18 to 40%) | 84.2 |
| Fat | 9 | 9.9 (band 5.5 to 20%) | 88.4 |
| Fibre | 2.5 | 2.8 (band 0.5 to 5%) | 100 |
| Calcium | 1.35 | 1.5 (band 0.5 to 2.5%) | 99.8 |
| Phosphorus | 0.8 | 0.9 (band 0.4 to 1.6%) | 94.2 |
| Sodium | 0.4 | 0.4 (band 0.1+%) | 100 |
| Calcium:phosphorus ratio | 1.7 | 1.7 (band 1 to 2%) | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 353.5 | 390.6 | 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.
Declared fortification: 10 nutritional additives on the label
- Vitamin A 12.000 IE
- Vitamin D3 1.200 IE
- Vitamin E 100 mg
- Kupfer (als Kupfer-(II)-Sulfat, Pentahydrat) 12,5 mg
- Zink (als Zinksulfat, Monohydrat) 100 mg
- Zink (als Glycin-Zinkchelat-Hydrat (fest)) 60 mg
- Eisen (als Eisen-(II)-Sulfat, Monohydrat) 200 mg
- Mangan (als Mangan-(II)-Sulfat, Monohydrat) 30 mg
- Jod (als Calciumjodat, wasserfrei) 1,5 mg
- Selen (als Natriumselenit) 0,35 mg
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 (1.2% of the recipe mass) (voluntary) | 0.2/20 |
| 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 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |
Capped at 60: mandatory items missing (Analytical constituents declared, Batch and date labelling).
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.
Claims on file; none we can check against the label
| Claim | Type | Check | Substantiation |
|---|---|---|---|
| Gesunde Haut & glänzendes Fell (on page) | Functional | not checkable | Manufacturer assertion |
| Für alle Hundegrößen (on page) | Functional | not checkable | Manufacturer assertion |
| Extra große Kroketten (on page) | Content | not checkable | Manufacturer assertion |
