Strengths

  1. Nutrition Fit 10.0 / 10AAFCO adequacy clears the rubric and dry-matter protein and fat land in the bands we expect.
  2. Low sensitivity risk 10.0 / 10Few of the most-named adverse-reaction trigger ingredients high on the label.
  3. Crude protein 40%High-protein bag on the guaranteed analysis panel.

Watch-outs

  1. Common triggers on the labelSkip if your dog avoids turkey, beef, 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. Ingredient Clarity 4.0 / 10Some sources are less specific than the rubric prefers - generic terms in the ingredient list, or fields we cannot verify.
