Wonderdog Grain-Free Beef & Sweet Potato
Dry Extruded complete Clear label
Is Wonderdog Grain-Free Beef & Sweet Potato a good dog food?
We score it 65/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Why this score?
This recipe achieves an overall score of 65 out of 100 based on several key factors. The meat content contributed +3.2 points, while the overall quality of the ingredient list added +6.8 points. However, the processing format reduced the score by -7 points, and ingredients without printed percentages resulted in a deduction of -3.3 points.
Only part of the analytical constituents are declared, so the nutritional picture is incomplete.

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 | 23 | 25 (band 18 to 40%) | 89.1 |
| Fat | 11 | 12 (band 5.5 to 20%) | 96.7 |
| Fibre | 3.5 | 3.8 (band 0.5 to 5%) | 100 |
Scored over 3 declared nutrients (combined weight 50); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 8% from the food type.
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 (75% of the recipe mass) (voluntary) | 15/20 |
| 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).
Safety: recall history

Evidence: what the brand claims, and what supports it
The marketing claims made on the pack and product page, and how much evidence sits behind them. We record the claims as stated; we do not assess whether they are true.
| Claim | Type | Substantiation |
|---|---|---|
| with Joint Care (on pack) | Functional | Manufacturer assertion |
| Supports muscle maintenance with quality beef protein (on page) | Functional | Manufacturer assertion |
| Supports joint health with added glucosamine & chondroitin (on page) | Functional | Manufacturer assertion |
| Gentle on digestion with a grain-free recipe (on page) | Functional | Manufacturer assertion |
| Complete and balanced to support long-term health, mobility, and performance (on page) | Functional | Manufacturer assertion |
| Grain-Free Beef & Sweet Potato (on page) | Content | Manufacturer assertion |
| 24% protein, 12% fat, and joint care (on page) | Nutrient | Manufacturer assertion |
| Balanced energy (12% fat) for steady performance without excess weight gain (on page) | High/low level | Manufacturer assertion |
Limited: at least one claim rests on manufacturer assertion alone.
