Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Has never failed my dogs

Easy topical application between the shoulder blades, although one dog fights me when applying, so I sneak it on him when I pass by.

No longer effective

Pet Armor has worked for years. Not this yr. My vet says fleas have gotten used to fipronil. I had to switch. If things were different, I'd still use it.

Pet Armor really works!

I've tried EVERY Flea treating Product Including Bravado and Serresto flea treatments on our dog who has an Immunity to most Everything and has been an Impossible

I've tried EVERY Flea treating Product Including Bravado and Serresto flea treatments on our dog who has an Immunity to most Everything and has been an Impossible exhausting ordeal for our house dog trying to keep her fleas down from one week to the next including weekly baths vigorously treating the house and lawn as well. We've finally gotten relief from our 1 dog flea hostel take over and only have to bathe her every other week now Thanks to Pet Armor Flea drops that her Veterinary Formula shampoo and leave in spray treatments can't work alone without Pet Armor!
