Our verdict
Is defu Bio Hundefutter Senior Bio-Geflügel a good dog food?
We score it 42/100 (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".
Only part of the analytical constituents are declared, so the nutritional picture is incomplete.
75% 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 senior dogs
- Doesn't list beef, lamb, fish, 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 grain: the label lists rice - white
- You want a single-protein recipe: this one lists more than one animal protein
- You need more protein than this: 20.0% on a dry-matter basis is in the low band
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?
This recipe achieves an overall score of 42 out of 100 based on several key factors. The overall quality of the ingredient list positively influences the result by adding +3.8 points. However, ingredients without printed percentages reduce the score by -7.9 points. Furthermore, the carbohydrate content deducts -7.7 points, and the processing format further reduces the score by -6.7 points.
Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

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 | 20 | 22.1 (band 18 to 40%) | 81.2 |
| Fat | 10 | 11 (band 5.5 to 20%) | 93 |
| Fibre | 3 | 3.3 (band 0.5 to 5%) | 100 |
| Calcium | 1.1 | 1.2 (band 0.5 to 2.5%) | 91.5 |
| Phosphorus | 0.9 | 1 (band 0.4 to 1.6%) | 99.7 |
| Calcium:phosphorus ratio | 1.2 | 1.2 (band 1 to 2%) | 83.3 |
Scored over 6 declared nutrients (combined weight 80); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.
Declared fortification: 9 nutritional additives on the label
- Vitamin A 18 000 I.E./kg
- Vitamin D3 1000 I.E./kg
- Vitamin E 140 mg/kg
- Eisen (Eisen(II)-sulfat-Monohydrat) 115 mg/kg
- Zink (Zinkoxid) 90 mg/kg
- Mangan (Mangan(II)-oxid) 14 mg/kg
- Kupfer (Kupfer(II)-sulfat-Pentahydrat) 12 mg/kg
- Jod (Kalziumjodat, wasserfrei) 1,4 mg/kg
- Selen (Natriumselenit) 0,15 mg/kg
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 (24.8% of the recipe mass) (voluntary) | 5/20 |
| 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 |
Capped at 60: mandatory items missing (Analytical constituents declared, 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.
0/100 · limited — 1 checkable claim: 0 consistent, 1 contradicted.
Contradicted by the label
- "Glutenfreie Rezeptur" — the declared label says otherwise on grain-free.
5 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.
