How PetScored scores.

We use a public, deterministic rubric. Five sub-scores. One composite. The rule events behind every score are visible on its product page. Same inputs, same score, every time.

Five promises

What deterministic means here

  1. 01

    Same inputs, same score.

    Scoring is deterministic. We do not run the rubric twice and pick the friendlier number. We do not let a single editor override a sub-score because they liked or disliked a brand.

  2. 02

    Receipts on every page.

    Every score is reconstructible from the data on its product page. Sub-scores show their rule events. Rule events show their evidence tier. Source confidence is labelled on every fact.

  3. 03

    One rubric per category.

    Dog food, supplements, insurance, diagnostics, and pet tech have completely different evidence problems. We refuse to bolt a five-dimension scorecard onto all of them. Each category waits until its rubric is defensible on its own terms.

  4. 04

    The rubric is versioned and public.

    We publish the rubric, we publish the changelog when it changes, and we recompute the affected scorecards so the history is honest.

  5. 05

    Affiliate revenue cannot move a score.

    PetScored makes money from readers and from affiliate links on retail-purchase actions. Affiliate revenue does not affect the rubric, the rule events, the sub-scores, or the order of any best-for list. If we ever change this, we will publish the change here first.

Active rubrics

Four categories live. The rest on the bench.

Dog Food

The first scored PetScored category, focused on label data, nutrition panels, source confidence, recall context, and value.

Cat Food

The second live scored category. Same five sub-scores as dog food, with cat-specific protein bands, a taurine declaration requirement (hard fail if missing on an adult diet), and a feline-allergen sensitivity profile.

Pet Supplements

The third live scored category. A deterministic rubric (v1.0) for joint, gut, skin and coat, calming, multivitamin, and liver supplements that weights evidence and delivered dose over marketing: a proprietary blend that hides its doses cannot earn a dose it will not disclose.

Treats & Chews

The fourth live scored category. A deterministic rubric (v1.0) for dental chews, biscuits, training treats, jerky, freeze-dried treats, and long-lasting chews: reframed from the food rubric because a treat is a snack, not a meal. Treat-specific Caloric Load and Claim Honesty replace Nutrition Fit and Sensitivity Risk, a dental claim earns credit only with a VOHC seal, and treats' outsized recall history weighs on Brand Trust.

  • Score unlike products with one universal rubric.
  • Let affiliate payouts, sponsorships, or manufacturer relationships move a score.
  • Publish scores in a category before the data sources and their limits are understood.
  • Make medical, financial, or diagnostic claims outside the published evidence.
  • Score a bag we cannot source-verify. See the refusal list.
