Product Description

Veterinarian-quality protection for your dog at significant savings.

Nothing should come between you and your dog, least of all fleas and ticks. So you need the most cost-effective protection money can buy. PetArmor is guaranteed to work effectively at killing adult fleas, ticks, and chewing lice. It contains the #1 veterinarian-recommended active ingredient, fipronil. It’s available in an easy-to-use, fast-acting topical application specifically formulated for your dog’s weight, so each monthly dose will give your dog the same protection at significant savings. That's great for both you and your dog. For dogs that live and play in heavily flea and tick infested areas, consider using PetArmorPro™ Advanced. It contains the same active ingredient, fipronil, as in PetArmor, but with an additional active ingredient that's clinically proven to work faster to kill adult fleas, ticks, and mosquitoes, and repel, which Frontline does not.

Is it normal to still see fleas and ticks on my pet a few days after treating it with PetArmor?

Yes. After treatment with fipronil, fleas and ticks get very active as they die and move to the top of the pet’s coat where they are more visible. This is actually a sign that the product is working. However, if you’re seeing fleas several days or weeks after applying PetArmor, you may have an infestation in your yard or elsewhere. Remember to treat all pets in your house with PetArmor every 30 days throughout the year to help protect your pets from fleas and ticks.

Can I use PetArmor more than once in a month if my pet has a really bad flea or tick problem?

No. PetArmor should not be used more than once every 30 days. If you have a bad infestation, talk to your veterinarian about your options.

Does PetArmor have an expiration date?

No. All PetArmor products should be stored at room temperature in their original packaging and are good to use as long as the pipettes remain sealed.
