Strengths

  1. Nutrition Fit 9.0 / 10AAFCO adequacy clears the rubric and dry-matter protein and fat land in the bands we expect.
  2. Low sensitivity risk 9.0 / 10Few of the most-named adverse-reaction trigger ingredients high on the label.
  3. Sensitivity Risk 9.0 / 10Sensitivity Risk is reconstructed from common allergen exposure patterns in the ingredient list.

Watch-outs

  1. Common triggers on the labelSkip if your dog avoids chicken, egg, fish. We surface this regardless of sub-score.
  2. Value 2.0 / 10Cost per 1,000 kcal is above the category median. Cheaper options exist with comparable nutrition.
  3. Partially verified source confidenceSome label or pricing fields rely on retailer-mediated capture rather than the manufacturer source. See evidence notes below.

Taurine declared on label (cat)Cat foods must declare taurine on the GA panel or in the ingredient list. AAFCO requires a minimum 1,000 mg/kg DMB for adult cat diets. PetScored scores the label declaration; failure to declare on adult or all-life-stages diets triggers a hard-fail floor at 4.0.
