Supplement rubric27 products scoredLast reviewed June 2026

Pet supplements, scored on evidence and dose.

The supplement aisle sells on ingredient names, not evidence. PetScored scores what the marketing will not: whether the primary active has credible evidence for its claim, and whether a daily serving actually delivers the studied dose. A best-selling joint chew can be beautifully made and still score mid because its headline active is weakly evidenced - and a proprietary blend that hides its doses lands in Limited. 27 products scored so far.

What we refuse, and what we hold

We do not score everything in the aisle.

We refuse to score products sold with explicit disease treatment, cure, or prevention claims (an unapproved drug claim, not a wellness product), prescription products, and actives whose legal status or species safety is unsettled, such as CBD. We hold a product out of scoring when its headline active is not yet in our cited evidence library - we add a sourced library entry before we score a product that leads with it, rather than guess a tier.

Scores are our opinion under a published rubric, not veterinary advice. We score the evidence and the disclosed dose, not whether a product will help an individual pet. Dosing and use are decisions for you and your veterinarian; see the medical disclaimer.
