Frontline® is a monthly application that kills 100% of fleas and their larvae within 24 to 48 hours.  In addition, Frontline® breaks the parasite life cycle, thus preventing them from laying eggs and reproducing.

Frontline® is applied between the shoulder blades on dogs.  It spreads naturally on the skin surface at the hair root level, aided by body movement to provide whole body coverage.

Frontline® A is water-resistant flea medication, so it continues to kill fleas even after a shampooing, swimming, rain or exposure to sunlight.

 Frontline® is for dogs over 8 weeks old.  Do not use Frontline plus on dogs less than 11 pounds.
