Our verdict
Is JosiDog Junior Duck & Potato a good dog food?
We score it 53/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Complete extruded dry food for puppies, with dried duck protein, potatoes and sweet potatoes as the main ingredients.
Only part of the analytical constituents are declared, so the nutritional picture is incomplete.
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
- Grain-free: no grain ingredients listed
- Doesn't list chicken, beef, turkey, lamb, venison, pork as ingredients
Consider something else if:
- Your dog avoids fish: the label lists hydrolyzed fish protein
- Your dog avoids duck: the label lists dried duck protein
- 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?
This recipe achieves an overall rating of 53 out of 100 based on several key factors. The overall quality of the ingredient list adds +4.9 points to the total. However, the processing format subtracts -6.7 points, and ingredients without printed percentages deduct -5.4 points. Additionally, the carbohydrate content contributes -3.9 points to the final assessment.
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 | 25 | 27.6 | 100 |
| Fat | 14 | 15.5 | 100 |
| Calcium | 1.4 | 1.5 | 100 |
| Phosphorus | 0.95 | 1 | 100 |
| Sodium | 0.45 | 0.5 (band 0.22+%) | 100 |
| Calcium:phosphorus ratio | 1.5 | 1.5 | 100 |
Scored over 6 declared nutrients (combined weight 75); 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 (49.3% of the recipe mass) (voluntary) | 9.9/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) - not on file | 0/10 |
| 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, Additives 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.
33/100 · limited — 6 checkable claims: 2 consistent, 4 contradicted.
Contradicted by the label
- "Mono protein - One land animal protein source" — the declared label says otherwise on single protein.
- "high-quality proteins" — the declared label says otherwise on high protein.
- "As the sole source of land animal protein" — the declared label says otherwise on single protein.
- "rearing food with 100% duck" — the declared label says otherwise on single protein.
Consistent with the label
- "This recipe contains no grain" — supported by the declared grain-free data.
- "Grain free formula" — supported by the declared grain-free data.
15 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.
