Our take on the PetArmor Plus Flea & Tick Spot Treatment

PetArmor Plus is a topical flea and tick treatment for dogs that uses fipronil plus an insect growth regulator, the same active ingredients as Frontline Plus. It kills fleas, flea eggs, larvae and ticks, and it is waterproof after drying. It suits owners who want a lower-cost alternative to vet-brand spot-ons and who are treating dogs in the labeled weight range. Reviewers often say it works when applied correctly, but some report irritation at the application site and inconsistent results on heavy infestations.

Questions and answers

Does PetArmor Plus work like Frontline Plus?
It uses the same two active ingredients, fipronil and (S)-methoprene, so the mechanism is the same. Many owners report similar results, though some find it less consistent on heavy infestations.
Is it safe for puppies?
Check the label for the minimum age and weight for the size you buy. It is not labeled for puppies below that threshold, and it should not be used on cats.
How often do I apply it?
Apply once a month. Reapply only after the labeled interval, and do not bathe the dog with shampoo for a couple of days before or after application.
Can I use it on a dog outside the weight range?
No. Match the tube to your dog's weight band; using a large-dog dose on a small dog raises the risk of side effects.
Is it waterproof?
Yes, it stays effective after swimming or bathing once the application site has dried. Avoid bathing for about 48 hours after applying.
What is in the box?
You get the number of single-dose applicator tubes shown in the pack count, along with the labeled instructions. There is no separate collar or spray.
Where is the PetArmor Plus Flea & Tick Spot Treatment cheapest?
At Walmart, for $39.97, as of our latest check.
