our rating

Is Alpha Adult Grain Free (Lamb) 15kg 24% Protein a good dog food?

We score it 59/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.

How we score

Why this score?

The overall score is 59 out of 100. The processing format contributed -7 points, while ingredients without printed percentages cost -4.5 and the carbohydrate content cost -3.9 points. Printing percentages on the label added +3.2 points back.

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

34% 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 sweet potatoes, pea starch and lamb as the main ingredients.

Consider something else if:

  • Your dog avoids chicken: the label lists poultry fat
  • Your dog avoids turkey: the label lists poultry fat
  • Your dog avoids lamb: the label lists lamb
  • Your dog avoids fish: the label lists fish meal
  • You want a single-protein recipe: this one lists more than one animal protein

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.

NutrientAs fed (label)Dry matter (scored)Score
Protein2426.1 (band 18 to 40%)92.1
Fat1010.9 (band 5.5 to 20%)92.2
Fibre3.53.8 (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.
