Pet Supplement Ad Rules: What You Can Claim and Show
A guide to advertising restrictions for pet supplements, covering allowed claims, common rejections, and compliant creative approaches.
Pet supplement ad rules mostly restrict health and medical claims: you generally can't say a product treats, cures, or prevents a disease in an animal, and platforms tend to require the same caution here as they do for human supplements, since pet owners are considered a persuadable audience and false pet-health claims are actively policed. Ads that stick to general wellness framing (support, comfort, mobility, coat health) rather than medical outcomes tend to clear review more reliably.
Why do pet supplement ads get the same scrutiny as human ones?
Supplements — for pets or people — sit outside strict pharmaceutical regulation in most places, which means platforms police the marketing claims themselves rather than relying on a drug approval process. Because pet owners often make health decisions emotionally and can't get direct confirmation from the animal that something worked, platforms and regulators treat exaggerated pet-health claims as a real risk of consumer harm.
What claims typically get rejected?
Anything implying the product treats or cures a named condition (arthritis, anxiety, cancer, allergies) is the most common rejection trigger, along with before/after imagery implying a medical transformation the product can't be proven to deliver. Testimonial-style claims ("cured my dog's seizures") are treated the same as brand claims — the source doesn't exempt it from policy.
What can you say instead?
Wellness-support language generally holds up better: "supports joint comfort," "formulated for coat and skin health," "may support digestive comfort" — framed as support rather than treatment or cure. Pair that with genuine ingredient transparency and usage context (when and how it's given) rather than a claimed medical outcome.
How do you build creative that still performs under these limits?
With the strongest claims off-limits, the ad needs to work through relatability and authenticity — real pet owners, real routines, honest framing of what the supplement supports rather than promises. Since that removes the easiest emotional lever (a dramatic cure story), it's worth testing more variations of the honest angle than you normally would, to find which framing of "support" actually earns attention in the first couple seconds of a vertical, 9:16 cut.
Where does Polaris fit?
Polaris builds AI UGC ads around your own product photos, and the AI actor delivers exactly the script you write — useful for staying inside wellness-support language rather than drifting into a claim you didn't intend. Connect the Polaris MCP to Claude, write the compliant angle, and generate a batch of variations in parallel to see which honest framing performs. Sharpen the hook with the hook generator, and once ads are live, measure performance with the ROAS calculator — see ROAS and hook rate for background. Full setup: generating ads inside Claude via MCP.
