Recipe: how the 1-100 score is calculated
Why this score?
The overall score is 39 out of 100. Undeclared ingredient shares, meaning ingredients without printed percentages, contributed -10.6 points, while the processing format contributed -6.7 points and the additive load contributed -4.2 points. The additives in the recipe added +3.3 points back. This is a general explanation of how the score works, not veterinary advice. For any health condition, food choice is a decision for your vet.

Safety: recall history
Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.
No recalls recorded in our database.

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.
0/100 · limited — 1 checkable claim: 0 consistent, 1 contradicted.
Contradicted by the label
- "Limited ingredient nutrition with a single, animal protein to avoid common allergens in dogs with food sensitivities" — the declared label says otherwise on single protein.
11 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.
