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.

Owners generally find PetArmor effective for routine flea and tick control on large dogs and like that it costs less than vet brands. Complaints center on the greasy, smelly application site and on fleas that reappear late in the month.
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.
