Pero Lamb & Rice Performance
Dry Extruded complete
Is Pero Lamb & Rice Performance a good dog food?
We score it 48/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Why this score?
This food achieves an overall score of 48 out of 100 based on several key factors. The overall quality of the ingredient list adds +7.1 points. However, ingredients without printed percentages deduct -13.1, the processing format removes -7, and the carbohydrate content subtracts -3.1.
Only part of the analytical constituents are declared, so the nutritional picture is incomplete.
100% of this recipe has no printed percentage. Estimated shares are model estimates, not label facts.

The Recipe score measures how attractive and transparent the declared ingredient list is. It is not, by itself, proof that the food is nutritionally appropriate for long-term feeding. The Nutritional and Evidence scores measure what we can verify towards that stronger claim.
Complete extruded dry food for adult dogs, with lamb, rice and tallow as the main ingredients.
Why you might choose it
- Single named animal protein: lamb.
- Nutritionally complete: formulated to be fed as the whole diet.
Why you might not
- Meat makes up an estimated 4% of the dry matter (13% as fed); carbohydrates dominate.
- 100% of the recipe mass has no printed percentage, so the exact split cannot be verified.

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 | 27 | 29.3 (band 18 to 40%) | 100 |
| Fat | 15 | 16.3 (band 5.5 to 20%) | 100 |
| Fibre | 2 | 2.2 (band 0.5 to 5%) | 92.3 |
| Calcium | 1.8 | 2 (band 0.5 to 2.5%) | 100 |
| Phosphorus | 0.9 | 1 (band 0.4 to 1.6%) | 98.9 |
| Calcium:phosphorus ratio | 2 | 2 (band 1 to 2%) | 100 |
Scored over 6 declared nutrients (combined weight 80); 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 (voluntary) - not on file | 0/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) | 5/10 |
| 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 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.
