How do you advertise pet supplements on Meta and Google without getting disapproved?

Sell support, not cures. Write about maintaining normal health (joints, digestion, coat) and never say the product treats, cures or prevents a disease. Do not imply you know the viewer's pet is sick. Keep the landing page as clean as the ad, hold evidence for every claim, and check that no ingredient is on a restricted list.

Why do pet supplement ads get disapproved so often?

Most rejections come from one of three places: a disease claim, copy that points at the viewer's personal situation, or an ingredient that a platform restricts. The ad networks are cautious about health products, and pet supplements sit right next to animal drugs in the rulebook.

The legal line matters because the platforms follow it. In the US, FDA explains that intended use decides what a product is: if the intended use is to treat or prevent a disease, the product is a drug. FDA also states that products marketed as dietary supplements for animals do not fall under DSHEA, the law that created the human supplement category. So a pet supplement is regulated as animal food or as an animal drug, depending on ingredients and claims.

Canada draws a similar line. Health Canada describes veterinary health products (VHPs) as low risk products used to maintain or promote the health and welfare of animals, and says they are not for use to treat, prevent or cure disease. Companies must notify Health Canada at least 30 days before selling a VHP there.

Put simply: the moment your ad reads like medicine, it is asking to be treated like medicine.

What do Google's policies say about supplements?

Google's Healthcare and medicines policy is the page to read first. Under unapproved substances, it does not allow:

• herbal and dietary supplements with active pharmaceutical or dangerous ingredients;
• products that claim to be as effective as prescription drugs or controlled substances;
• non-government-approved products marketed as safe or effective to prevent, cure or treat a disease or ailment;
• products subject to any government or regulatory action or warning.

The same policy restricts prescription drug terms in ads, keywords and landing pages. That matters for pet brands that compare themselves to a named prescription drug. Comparison copy like "a natural alternative to [drug name]" can pull in a restricted term and a claim of equal effect in one line.

On Google Shopping, this policy applies to your product titles, descriptions and landing pages, not just text ads. A feed title like "Hip and Joint Chews for Arthritis" can disapprove a product that would pass as "Hip and Joint Chews with Glucosamine for Senior Dogs".

What do Meta's advertising standards say?

Meta has three sections that hit pet supplement brands most:

• Privacy violations and personal attributes. Ads cannot assert or imply that the viewer has a health condition. Meta's own examples of what is not allowed include "Do you have diabetes?". Pet copy runs into the same rule when it reads as if you know the viewer or their family has a problem.
• Health and wellness. Ads for dietary and health products must be targeted to people 18 or older. Health ads also cannot promise specific outcomes within a set timeframe without qualifiers.
• Drugs and pharmaceuticals. This covers unsafe substances and supplements. Its CBD section bars claims that a product can treat, cure, prevent, mitigate or diagnose a disease in humans or animals, and CBD ads need prior written permission from Meta.

Setting an 18+ age floor on pet supplement campaigns costs you very little, because the buyer is an adult pet parent anyway, and it removes one easy reason for rejection.

Which claims are safe and which are risky?

Use this table as a first filter. It is not legal advice, and your regulatory adviser has the final word on your exact product.

Two notes on the table. First, the word "proven" needs proof. AAFCO's label guidance says "proven" is prohibited on pet food labels without scientific or empirical evidence, and the FTC says advertisers must have proof before the ad runs. Second, the same line holds in Canada: VHPs maintain or promote health, and disease treatment claims are outside what they are for.

How do you write ad copy that passes review?

Work through this checklist for every new ad, every feed title and every landing page.

1. Name the function, not the disease. "Joint support" and "digestive support" work. "Arthritis" and "IBD" do not belong in ad copy.
2. Talk about the pet, not the viewer. Prefer "Built for senior dogs" over "Is your senior dog struggling?".
3. Drop time promises. "Results in 7 days" is the kind of specific outcome that Meta's health policy flags without a qualifier.
4. No drug names. Do not compare yourself to a prescription product by name.
5. Check ingredients against the lists. If an ingredient is on Google's unapproved substances list or touches CBD, plan for restrictions before you build the campaign.
6. Hold the evidence. Keep a claims file: each claim, the study or data behind it, and who approved it.
7. Clean the landing page. Reviews, FAQs, blog links and product names on the page count. One five-star review saying "cured my dog's arthritis" on your product page can sink the ad.
8. Match the label. If your label says "supports healthy joints", your ads should not go further than your label.

What should you do after a disapproval?

Do not rush to appeal. Read the policy named in the rejection, then find the exact word or image that triggered it. Fix the ad and the landing page together, then request review. Appealing the same copy again rarely changes the result, and repeated violations can put the whole account at risk.

Keep a simple log: date, ad, policy cited, fix made, result. After a few weeks you will see a pattern, and that pattern becomes your house style guide. If you run Shopping, apply the same fixes to your feed titles. Our guide to Shopping feed optimisation for pet products covers how to rewrite titles without losing relevance.

How does creator content fit in?

Creator videos are where disease claims slip in most, because real pet parents speak freely. A creator saying "this fixed my dog's arthritis" on a paid ad is your claim, not theirs. Brief creators with the same safe language list you use for ads. Our UGC brief guide shows how to write that list into the brief.
