Our take on the PetArmor CapAction Flea Tabs for Dogs

PetArmor CapAction is an oral flea tablet for dogs and puppies 4 weeks and older weighing at least 2 lbs. Each tablet contains 11.4 mg nitenpyram and starts killing adult fleas within 30 minutes, with over 90% effectiveness within 6 hours. It is a fast knockdown product, not a monthly preventive, so it works best alongside a longer-acting flea control. Owners like the speed and the option to hide it in food; the main complaints are that it does nothing for ticks or eggs and that fleas can return if no preventive follows.
