FRONTLINE Plus is a monthly flea and tick spot treatment for medium dogs weighing 23–44 lb (10.4–20 kg), supplied as a count of 3.

  • Fipronil and (S)-methoprene target adult fleas, flea eggs and flea larvae to disrupt the flea life cycle.
  • Kills ticks, including ticks that can transmit Lyme disease, and chewing lice.
  • One dose protects against fleas and ticks for 30 days.
  • Waterproof 24 hours after application, so protection continues if your dog gets wet.
  • Stops existing flea infestations and helps prevent new infestations from becoming established.
  • Aids in the control of sarcoptic mange infestations.

For dogs with fleas or ticks, treatment needs to address more than adult fleas alone: flea eggs and larvae can contribute to further infestations. FRONTLINE Plus is made for monthly use on medium-breed dogs in its specified weight range. It offers topical flea and tick protection for regular home use, with a formula designed to act across flea life stages as well as against ticks and chewing lice.

What parasites does FRONTLINE Plus target?

FRONTLINE Plus kills adult fleas, flea eggs, flea larvae, ticks and chewing lice. Its fipronil and (S)-methoprene formula targets existing adult fleas and immature flea stages, helping break the flea life cycle rather than focusing on adult fleas alone.

The treatment also helps stop current flea infestations and prevent new ones from becoming established. It kills ticks that can transmit Lyme disease and aids in the control of sarcoptic mange infestations. FRONTLINE is the number 1 name in flea and tick protection, and pet owners have trusted the brand for over 20 years.

  • Targets several flea life stages in one topical treatment.
  • Includes chewing lice and ticks among the parasites it kills.

How does the spot treatment work?

Apply the treatment to a single point on your dog; it spreads over the body and deposits in the sebaceous glands. These glands act as a reservoir that continually replenishes treatment onto your dog, including when your dog gets wet.

The treatment is waterproof 24 hours after application. It is fast-acting and long-lasting, with one dose providing flea and tick protection for a full 30 days. The single-point application makes the topical format straightforward to use, and the treatment is designed for monthly application.

  • Applied at one point, then distributed over the dog’s body.
  • Waterproof 24 hours after application.

Which dogs is this three-dose pack made for?

This FRONTLINE Plus formula is for medium dogs weighing 23–44 lb (10.4–20 kg). The pack contains 3 doses, with each dose intended to provide 30 days of flea and tick protection.

FRONTLINE Plus for Dogs can be used on puppies from 8 weeks of age that weigh at least 5 lb (2.3 kg). For this specific medium-dog formula, compare your dog’s weight with the 23–44 lb range. FRONTLINE Plus is also available in a separate formula for cats and kittens aged 8 weeks and older that weigh at least 1.5 lb (0.7 kg); this pack is the dog formula.

  • Three doses are included.
  • The medium-dog weight range is 23–44 lb (10.4–20 kg).

How often should FRONTLINE Plus be applied?

Apply FRONTLINE Plus monthly to maintain flea and tick protection. Treating all pets in the household monthly helps control fleas and ticks and prevent new flea infestations from becoming established.

FRONTLINE Plus is designed for routine flea and tick control at home, including for dogs that may get wet after the 24-hour period following application. Its monthly schedule and topical application make it suitable for pet owners who want to address adult fleas, flea eggs, flea larvae and ticks as part of an ongoing flea-control routine.

  • Use the dog formula for dogs and the separate cat formula for cats.
  • Monthly treatment of all household pets helps control fleas and ticks.

FRONTLINE Plus suits owners of medium dogs within the 23–44 lb range who want a topical treatment that targets multiple flea stages, ticks and chewing lice on a monthly schedule. Puppies must be at least 8 weeks old and weigh at least 5 lb to use FRONTLINE Plus for Dogs. Its three-dose pack provides monthly treatment for dogs in the specified medium-dog weight range.
