Compare Pet Armor to Frontline

It's simple. The same active ingredients and the same flea and tick protection as Frontline.

For years, Frontline was the only flea and tick medication of its kind on the market. Now Pet Armor™ offers the same active ingredient (fipronil), in the same concentration as Frontline, so it's just as safe and effective against fleas and ticks. Fipronil is the number-one active ingredient recommended by veterinarians for flea and tick control. Also, Pet Armor Plus contains S-methoprene, just like Frontline Plus, which prevents flea eggs from hatching and growing up, and then laying more eggs.

Why the same, for less?*

Pet Armor is a generic version of Frontline with the same active ingredient—fipronil. The fipronil patent (U.S. Patent # 5,232,940) has expired, clearing the way for generic products to be available. We've made it up to 50% less expensive* and available in stores where you shop, because we'd like to help more pets stay flea and tick free.
