Our take on the PetArmor Flea & Tick Spot Treatment for Dogs, 5-22

PetArmor's topical flea and tick treatment uses fipronil, the same active ingredient as Frontline, applied monthly between the shoulder blades. It kills adult fleas, chewing lice and several ticks, including deer ticks, and is waterproof once dry. It suits small dogs and puppies from 8 weeks old weighing 5 to 22 lbs. Owners report it works well for routine flea control and is less oily and less smelly than some rivals, but some still find attached ticks and say it does not clear an existing infestation on its own.
