Bertha's Barkery

We have been seeing more counterfeit Seresto Collars this year than any other year. Most of these collars are bought online. Our first clue to a counterfeit S...eresto Collar is clients saying it does NOT work and the pet has fleas. We can easily tell if the collar is counterfeit. Most of the counterfeit collars have an odor and/or the container looks like the labels are glued on. This collar below, we had a client bring in today, was the best counterfeit we have seen. We contacted Bayer (maker of Seresto) and it is a counterfeit. Seresto collars should have NO dates on the tin. The inside of the tin color should have a metallic sheen. The print on the collar should be lasered/etched in collar, not stamped on collar . The FDA is warning consumers to be cautious when buying any medication or preventative for your pet online. Buy from a reputable store or veterinarian. When in doubt ask us or call the the maker of the product.(1-800-255-6826 is Bayer’s Consumer Contact Number) See more
