Frontline Plus is a monthly topical spot treatment for dogs that kills fleas, flea eggs and larvae, and ticks. It uses fipronil to kill adult fleas and (S)-methoprene to stop eggs and larvae from developing, which breaks the flea life cycle. It is waterproof after drying and sold in multi-dose packs, so one box covers several months. It suits dog owners who want a simple monthly application rather than an oral chew, but it is not for puppies under 8 weeks or dogs outside the labeled weight band.
