Frontline Shield is a spot-on flea and tick treatment for dogs, sold here as a three-dose pack for medium to large dogs (11–44 kg). It combines fipronil with permethrin, which adds repellent action against ticks and mosquitoes that plain fipronil products lack. Each dose protects for about a month, so the pack covers roughly three months. It suits owners who want a broad-spectrum, repellent spot-on for a medium or large adult dog, but it is not for cats and not for puppies under the label's minimum age.

Owners generally find Frontline Shield effective for fleas and easy to apply, and many value the tick and mosquito repellence over plain fipronil drops. Complaints centre on skin irritation at the spot, lingering smell, and ticks still found on dogs in high-exposure areas.
