PetArmor CAPACTION (nitenpyram) Oral Flea Treatment for Dogs, Fast Acting Tablets Start Killing Fleas in 30 Minutes, Dogs Over 25 lbs, 6 Doses

This works. It isn’t quite as fast as the more expensive brand name, but it will work. I have cats and weight out portions of the large dog size for dose because the ingredients are the same. It save me a lot of money for a little trouble.It must be bitter, so I mix the dose with some Delectable brand cat treat and mix it in. Dosing one cat at a time. Goes medium fast. You will start to see groggy fleas falling off with a hour. They will die, but it is not an instantaneous process. Spray your house at the same time and then redose in a few days.This is not a medicine that lasts. It’s gone in 24 hours and yes, your pet can be re infested after that time. That why all pets must be done the same day and anywhere the pet sleeps or walks or hangs out in must be treated for fleas. Breaking the chain is the bane if the game. Respray areas when you retreat the animals.
