The listing looks exactly right. Same box, same beloved brand, same smiling dog, half the price of the vet's shelf. What arrives might be the genuine export stock. It might also be a tube of flavoured nothing, or a cat product's chemistry in a dog product's box, and with medicines the difference is not a disappointing purchase. It is an untreated infestation at best and an emergency visit at worst.
Regulators in the US and Europe have warned about counterfeit pet medicines for years, and seizures keep turning them up in the same discount channels that move fake everything else. The packaging is the easy part to copy. The pharmacology is the part that matters.
Counterfeit board games are usually printed from scans of the genuine components, so the tells are physical: thin card stock, washed or misregistered colours, soft focus art, and rulebook text with translation artefacts the original never had. The price gap exists because scanning is cheap and licensing, illustration, and decent printing are not.
Clone listings copy more than product photos. They lift review text and customer photos from the genuine listing so the fake arrives pre trusted, with a rating history for an item the seller never sold. The seams show in details: reviews describing features the clone lacks, customer photos of packaging the clone does not ship, and a review timeline older than the seller's account.
Open the oldest reviews first. If they predate the seller's account or the listing itself, the history was imported, not earned. Read for specifics and check them against the listing: a review praising the genuine product's accessory, material, or packaging that the clone's own photos do not show is a lifted review describing a different item. Customer photos deserve the same check; a photo showing branded packaging in a listing whose own images show plain packaging is evidence sitting in plain sight.
Review language betrays bulk lifting too. The same phrases appearing under multiple unrelated clone listings, and review sets that jump from dozens of five stars to a recent run of complaints about quality, describe a listing whose early trust was manufactured and whose real product arrived later in the record. Sort by most recent to see what current buyers actually received.
Automated systems compare listings for copied images and text far more readily than copied reviews, because reviews live in a different system with legitimate reasons to mention the same product. A clone can also hide under a variation or a slightly altered title that defeats exact matching. That is why human reports that connect the dots, genuine listing here, clone there, these reviews identical, this customer photo showing packaging the clone does not use, are disproportionately effective: they hand the reviewer the comparison the automation missed.
Brands should run this check on their own catalogue on a schedule. A clone with stolen reviews converts better than a bare clone, so it is the version that does the commercial damage, and it is findable in minutes per product once looking for review overlap is part of the routine rather than a reaction to a customer complaint.
Buy from the listing the brand links to, or a seller the brand lists as authorised, and treat any other listing using identical imagery as a separate, unverified product regardless of its displayed rating. Ratings attach to listings, and a cloned listing's rating is a costume. If the price difference tempts you anyway, let it be for a reason you can verify, an authorised outlet, a documented sale, not because five stars were copied along with the photographs.
Report clones you find even when you did not buy. The report costs a minute, feeds the comparison systems, and is often how the genuine brand learns the clone exists. Silence is the business model: clones depend on most visitors never checking, and on the few who notice assuming someone else reported it.

Clone sellers copy review text and customer photos into their own listings or seed listings on platforms where listings can be created freely. The reviews describe the genuine product, which is why checking them against the clone's actual features exposes the copy.
Reviews older than the seller's account, or customer photos showing packaging and accessories the listing itself does not offer. Either takes under a minute to check and neither occurs on a genuine listing.
Trust it after the seams check: review dates versus account age, specifics versus the listing's own photos, and the most recent reviews' content. A rating that survives those checks means something; one that fails them is decoration.
Reports that include the side by side comparison, genuine listing, clone listing, duplicated reviews identified, are acted on far more often than a bare fake flag, because the reviewer receives the evidence assembled. It is worth the extra two minutes.
