Our verdict

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.

Complete extruded dry food for adult dogs, with lamb, rice and tallow as the main ingredients.

How we score

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.

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.

Who is this food for?

Suits

Labelled by the manufacturer for adult dogs
Single named protein: lamb
Doesn't list chicken, beef, turkey, fish, venison, pork, duck as ingredients

Consider something else if:

Your dog avoids grain: the label lists rice - white

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 a final score of 48 out of 100 based on several key factors. The overall quality of the ingredient list added +6.6 points. However, ingredients without printed percentages reduced the score by -10.6. Additionally, the processing format deducted -6.7 and the carbohydrate content contributed -3.1.

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 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	29.8 (band 18 to 40%)	100
Fat	15	16.6 (band 5.5 to 20%)	100
Fibre	2	2.2 (band 0.5 to 5%)	92.8
Calcium	1.8	2 (band 0.5 to 2.5%)	100
Phosphorus	0.9	1 (band 0.4 to 1.6%)	99.7
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 9.5% from the food type.

Declared fortification: 10 nutritional additives on the label

Vitamin A 24,500 IU
Vitamin D3 2,450 IU
Vitamin E 245mg
Zinc (as Zinc Oxide) 69mg
Iron (as Iron (II) Sulphate Monohydrate) 30mg
Manganese (as Manganese (II) Oxide) 25mg
Manganese (as Manganous Sulphate Monohydrate) 25mg
Copper (as Copper (II) Sulphate Pentahydrate) 10mg
Iodine (as Calcium Iodate Anhydrous) 1.5mg
Selenium (as Organic Selenium) 0.2mg

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

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 — 3 checkable claims: 1 consistent, 2 contradicted.

Contradicted by the label

"high in protein" — the declared label says otherwise on high protein.
"high fibre" — the declared label says otherwise on high fibre.

Consistent with the label

"single source lamb protein recipe" — supported by the declared single protein data.

10 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.
