Because of widespread counterfeiting and bootlegging, Bayer
has changed the package design of Advantage in every country where it is distributed. Bayer only sells Advantage through licensed veterinarians, so if you purchase it from a
pet store or on line, the seller did not buy their products legitimately from Bayer, the manufacturer. One way these sources sell Advantage is by using product from other countries, and this new box design will make the illegal sale of foreign product, as well as the illicit printing of
fake Advantage boxes, more difficult.
