Our take on the PetArmor plus flea & tick treatment for large dogs

PetArmor Plus is a topical flea and tick treatment for dogs that uses fipronil plus (S)-methoprene, the same active ingredients as Frontline Plus. It kills adult fleas, flea eggs and larvae, and ticks, and it is waterproof after drying. It suits owners who want a vet-style topical at a lower cost than brand-name equivalents. Reviewers generally find it effective on fleas but report more skin irritation and residue than with pricier brands.

Questions and answers

Is PetArmor Plus the same as Frontline Plus?
It uses the same two active ingredients, fipronil and (S)-methoprene. The carrier formula differs, which is why some owners report more residue or irritation.
How often do I apply it?
Once a month. Each tube protects for about 30 days, and the multi-pack covers several months.
Is it waterproof?
Yes, once the application site has dried. Avoid bathing the dog for about 48 hours after applying.
Which tube size does my dog need?
Match the tube to your dog's weight. Large dogs generally need the 45 to 88 lb tube; do not split tubes between dogs.
Can I use it on puppies?
It is labeled for puppies from 8 weeks of age and for breeding, pregnant and nursing dogs. Check the label for your dog's weight.

Bathe the dog with mild soap if you see irritation and contact your vet. Stop use if signs persist.
