K9 Praventa 360 for Dogs is a fast-acting, monthly topical flea & tick treatment. Containing Imidacloprid, Permethrin and Pyriproxyfen, the same active ingredients found in the leading veterinary brand, K9 Praventa 360 for Dogs is a vet-quality, broad-spectrum treatment that kills and repels fleas and ticks on contact. Applying a topical is important to control flea infestations. K9 Praventa 360 for Dogs not only kills adult fleas but affects each life stage, continuing to work by preventing flea eggs and larvae from developing. The benefit of a topical is that it kills pests on contact rather than by ingestion, therefore it does not enter the pet’s bloodstream. K9 Praventa 360 provides long-lasting protection, controlling fleas and ticks within one day of treatment and continuing to protect the dog from further infestation for up to four weeks.*This product is not manufactured or distributed by Bayer, the maker of K9 Advantix® II for dogs.
