Once applied to the dog or cat's skin, Advantage spreads naturally on the surface of the skin at the hair follicle level, providing whole body coverage. It keeps killing for up to four weeks, even if your dog has a bath or goes swimming. Another notable benefit of Advantage is its proven larvicidal activity. Dogs and cats shed their skin cells daily. Therefore, when this product is applied, some portions of it are shed off with the skin, treating the environment.
Advantage can kill fleas and keep further populations from developing.
No more messy flea sprays or dips are needed for your dogs and cats. It is the same chemical that is in Sentinel for dogs. Program does not kill adult fleas, but as soon as a female flea bites a treated animal, the flea will be unable to reproduce. If your dog or cat has a flea infestation, we recommend another flea product such as Advantage used in conjunction with Program.
