A single dose kills adult fleas on your dog. Because advantus™ does not have an effect on fleas in the environment, your dog may become re-infested with fleas. If your dog becomes re-infested, you can safely repeat treatment as often as once a day. Contact your veterinarian if you have any questions about flea infestations on your dog.

Treat all pets in your household with a flea protection product. advantus™ should only be given to dogs.

Flea Infestations on Dogs: Treatment of flea infestations is important to your dog’s health. Fleas in your dog’s environment can re-infest your dog. Therefore, you may need to treat with advantus™ more than one time. The following diagram illustrates the flea’s life cycle and where advantus™ works:

Fleas reproduce rapidly. A single female flea may produce up to 2,000 eggs over her lifetime. Eggs hatch and may grow into adults in only three weeks. Adult female fleas feed by ingesting blood from your dog and lay eggs that drop off from your dog’s coat. Within days, larvae hatch from these eggs and live undetected in your dog’s surroundings, such as in the carpet and bedding. Fleas can emerge to re-infest your pet, continuing the life cycle. When these new fleas are seen on your dog, treat with advantus™.

If you have any questions about flea treatment or medical problems associated with flea infestations, consult your veterinarian.

Storage Information: Store at temperatures between 68° and 77°F (20°-25°C).
