our rating

Is Purizon Original Fish – Grain-free a good dog food?

We score it 71/100 (Good). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.

How we score

Why this score?

This food achieves a score of 71 out of 100 based on several key factors. The overall quality of the ingredient list adds +9.8 to the total, while the processing format reduces the score by -7. Additionally, the meat content contributes +6.9, and printing percentages on the label adds +3.2.

Only part of the analytical constituents are declared, so the nutritional picture is incomplete.

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 salmon, herring and plaice as the main ingredients.

Why you might choose it

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.

Omega fatty acids (omega-6 and omega-3)--100
Energy (kcal/100g)397431.5100

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 8 declared nutrients (combined weight 100); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 8% from the food type.

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.
