Bonza Superfoods & Ancient Grains
Dry Extruded complete Clear label
Is Bonza Superfoods & Ancient Grains a good dog food?
We score it 57/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Why this score?
This recipe achieves a total score of 57 out of 100 based on several key factors. The overall quality of the ingredient list adds +7.5 points to the total. However, the processing format results in a deduction of -7 points. Additionally, ingredients without printed percentages reduce the score by -5.2 points, and the carbohydrate content contributes a further deduction of -4.7 points.
40% of this recipe has no printed percentage. Estimated shares are model estimates, not label facts.

Complete extruded dry food for dogs of all life stages, with sweet potatoes, oat flakes and peas as the main ingredients.

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 | 25 | 27.5 (band 18 to 40%) | 95.8 |
| Fat | 12.5 | 13.7 (band 5.5 to 20%) | 100 |
| Fibre | 4.5 | 4.9 (band 0.5 to 5%) | 100 |
| Calcium | 0.9 | 1 (band 0.5 to 2.5%) | 84.7 |
| Phosphorus | 0.7 | 0.8 (band 0.4 to 1.6%) | 88.5 |
| Calcium:phosphorus ratio | 1.3 | 1.3 (band 1 to 2%) | 87.1 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 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 7 declared nutrients (combined weight 90); undeclared nutrients do not affect the score.
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 (60.2% of the recipe mass) (voluntary) | 12/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 10/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) - not on file | 0/10 |
| 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 (Feeding guidance given, Batch and date labelling).
