Frequently Asked Questions

How does FRONTLINE® Plus for Dogs work?

FRONTLINE® Plus for Dogs spreads from the single point of application, rapidly covering the entire dog and localizing in the hair, on the surface of the skin and in the sebaceous glands. These glands act as a reservoir, continuously replenishing FRONTLINE Plus for Dogs onto the skin and hair coat, so it keeps working even if the dog gets wet.

Why is it important to tackle flea eggs as well as fleas?

Even if you have treated your pet for fleas, some fleas may lay eggs before dying, therefore it is important to tackle flea eggs. FRONTLINE Plus for Dogs kills fleas before most have time to lay eggs. The (S)-methoprene in FRONTLINE Plus for Dogs prevents development of flea eggs and flea larvae, breaking the flea life cycle.

Can my dog get wet right after applying FRONTLINE Plus for Dogs?

Your dog needs to be dry at the time FRONTLINE Plus for Dogs is applied and remain dry 24 hours after application.
