How to avoid fake Seresto® collars

Due to the widespread popularity of Seresto® flea and tick collars, pet owners might come across fake imitation collars. Your pet is our top priority, so here are some tips for how to ditch the dupes.

How we're fighting fakes

Fake Seresto® collars are ineffective and can put your furry friend at risk for expensive flea and tick infestations, and painful flea and tick bites, which can result in transmission of certain diseases. We're working to eliminate counterfeit collars by removing counterfeits from e-commerce and brick-and-mortar retailers, training law enforcement and customs officials, and creating packaging and labeling innovations. 

As an additional layer of precaution, we want to empower pet owners to spot fakes for themselves. Here are some tips on how to tell if a Seresto® collar is real.
