Our verdict
Is Pero 80/20 Fish a good dog food?
We score it 54/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Complete cold-pressed dry food for dogs of all life stages, with trout, sweet potatoes and goose as the main ingredients.
100% 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 all lifestages
- Grain-free: no grain ingredients listed
- Doesn't list chicken, beef, turkey, lamb, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids fish: the label lists trout
- 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.

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 | 51.2 | 55.2 (band 18.932038834951456 to 40%) | 100 |
| Fat | 17.9 | 19.3 (band 5.784789644012945 to 20%) | 100 |
| Fibre | 2.4 | 2.6 (band 0.5 to 5%) | 97.9 |
| Calcium | 1.1 | 1.2 (band 0.5258899676375405 to 2.5%) | 90.1 |
| Phosphorus | 0.7 | 0.8 (band 0.4207119741100324 to 1.6%) | 87 |
| Calcium:phosphorus ratio | 1.6 | 1.6 (band 1 to 2%) | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 66.4 |
| Energy (kcal/100g) | 390 | 420.7 | 100 |
Omega fatty acids (omega-6 and omega-3): scored as the mean of its declared components (omega-6 66.4). The FEDIAF minimum for omega-6 is linoleic acid specifically.
Scored over 8 declared nutrients (combined weight 100); undeclared nutrients do not affect the score.
Declared fortification: 5 nutritional additives on the label
- Vitamin A 1500 iu/kg
- Vitamin B6 7.5 mg/kg
- Vitamin C 51 mg/kg
- Vitamin D3 175 iu/kg
- Vitamin E 1 mg/kg
High confidence: full analysis plus minerals or omegas and declared energy.
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 (0.3% of the recipe mass) (voluntary) | 0.1/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| Additives declared (mandatory) | 5/10 |
| Energy value declared (voluntary) | 5/5 |
| 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 (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.
100/100 · moderate — 1 checkable claim: 1 consistent, 0 contradicted.
