Our take on the PETARMOR Flea & Tick Treatment for Large Dogs, 45 to 88 Pounds, 3 Monthly Applications

PetArmor is an over-the-counter topical flea and tick treatment for dogs 45 to 88 pounds, sold in three monthly tubes. It uses fipronil, the same active ingredient as Frontline, and kills adult fleas, ticks and chewing lice for up to 30 days per application. It is waterproof and starts working soon after application. It suits owners who want a lower-cost alternative to vet-channel brands and are willing to apply a liquid between the shoulder blades. Unlike chewables, it leaves a greasy spot for a day or two, and it does not kill flea eggs, so a home flea problem needs separate treatment.

About the PETARMOR Flea & Tick Treatment for Large Dogs, 45 to 88 Pounds, 3 Monthly Applications

PETARMOR Flea & Tick Treatment is a topical treatment for large dogs weighing 45 to 88 pounds. It kills adult fleas, ticks, and chewing lice for up to 30 days. The formula is fast-acting and waterproof, and it starts working right away.

Each pack contains 3 tubes, one for each monthly application. To apply, remove one tube and cut off the top. Use the open end to part the dog's hair, then squeeze the tube firmly so that all of the solution goes onto the skin between the shoulder blades.

Keep treated dogs apart from each other, other pets, and children for 24 hours, until the product has dried completely.

Questions and answers

Does PetArmor work as well as Frontline?
Both use fipronil as the active ingredient, so the flea and tick kill is comparable. PetArmor is not the same formulation, and some owners find it wears off sooner.
Does it kill flea eggs?
No. It kills adult fleas, ticks and chewing lice. Flea eggs and larvae in the home need a separate treatment or an insect growth regulator.
How often do I apply it?
One tube per month, up to 30 days of protection. Do not reapply sooner than the label allows.
Can I bathe my dog after applying it?
Yes, once the product has dried completely. It is waterproof after that, but avoid bathing in the first day or two.
Is it safe around other pets and children?
Keep the treated dog apart from other pets and children for 24 hours until the application site is dry. Do not let pets lick the spot.
Which dogs is this size for?
Dogs weighing 45 to 88 pounds. Smaller or larger dogs need the matching weight-band product.
