PetArmor Plus is a monthly topical flea and tick treatment for dogs weighing 23-44 lbs. It uses fipronil and (S)-methoprene, the same two active ingredients as Frontline Plus, and kills adult fleas, ticks and chewing lice while stopping flea eggs and larvae from developing. Each box holds 3 applicators, a 3-month supply. At $13.99 at PetArmor as of November 4, 2026, it sits at the low end of its recent range and is among the cheapest ways to buy a 3-month supply.
