    The long-lasting Seresto antiparasitic collar works by preventing the Leishmania mosquito and external parasitosis for eight months. Its function is to prevent the spread of mosquitoes, fleas, ticks and lice, in addition to protecting the home from these annoying parasites. It is a collar designed by experts and veterinarians, subjected to rigorous quality controls that guarantee its safety, both for the dog and the rest of the family. By releasing small doses of its active ingredients, it can be used in puppies from 7 weeks of age.

    Seresto is developed by the Elanco brand (previously Bayer), with the aim of improving the quality of life and health of pets. The collar is composed of several materials that allow the controlled release of active ingredients.

    The collar contains Imidacloprid which kills and prevents the multiplication of fleas and lice. On the other hand, flumethrin prevents ticks from feeding on the animal's blood. These components are found in the matrix of the collar and only the doses indicated when placing it are released. The active ingredients spread over the surface of the animal, protecting it from any external invasion.

    Its ingredients are dermatologically tested so as not to harm the dog's skin. In fact, it can be used as a treatment for allergic dermatitis due to flea bites, as it softens irritations and regenerates the skin. It is a waterproof dog item. It is suitable for all races.
