Seresto is Bayer's collar for dogs that acts effectively against fleas and ticks and their larvae in the environment. Seresto uses a new combination of materials that releases appropriate doses of active ingredients in a controlled manner for 8 months. It provides excellent protection for your dog, not only because it kills fleas and ticks, but also because it repels ticks before they bite and ingest blood, which helps protect your animal from the diseases that these parasites can transmit. Furthermore, results from two clinical field studies conducted in Leishmania infantum endemic areas show a significant decrease in the risk of Leishmania transmission by sandflies in treated dogs compared to untreated dogs. Hypoallergenic. Protect your dog for up to 8 months. Waterproof
