Frontline Plus Flea and Tick Treatment for Medium Dogs, 23–44 lb, 6 Doses

FRONTLINE Plus is a monthly topical flea and tick treatment for medium dogs weighing 23–44 pounds (10.4–20 kg), supplied as six doses for ongoing protection.

• For dogs weighing 23–44 pounds — choose the dose range made for your medium-sized dog.
• Six doses, each protecting for 30 days — supports a monthly flea and tick treatment routine.
• Fipronil and (S)-methoprene target adult fleas, flea eggs and flea larvae — addresses multiple stages of the flea life cycle.
• Kills ticks and chewing lice, and aids in controlling sarcoptic mange infestations — covers additional common parasites.
• Applied at one point and distributed across the body — treatment is stored in the sebaceous glands and replenished onto your dog.
• Waterproof 24 hours after application — the treatment continues to work if your dog gets wet after that period.

Fleas can persist through different life stages, so treating adult fleas alone may leave eggs and larvae behind. FRONTLINE Plus is made for monthly flea and tick control, including helping stop an existing flea infestation and preventing new infestations from becoming established. Its topical application suits dog owners looking for a treatment that works across the body rather than a product limited to the application spot.

What parasites does FRONTLINE Plus for Medium Dogs target?

FRONTLINE Plus kills adult fleas, flea eggs, flea larvae, ticks and chewing lice. Its two active ingredients, fipronil and (S)-methoprene, work together to address adult fleas as well as flea eggs and larvae, helping break the flea life cycle. The treatment also aids in the control of sarcoptic mange infestations.

• Ticks targeted by the treatment can transmit Lyme disease.
• Designed to help control existing flea infestations and prevent new ones from becoming established.

How does the topical treatment work, including after a dog gets wet?

Apply the dose to a single point on your dog; the treatment then covers the body and collects in the sebaceous glands. These glands serve as a reservoir, continually replenishing the treatment onto your dog. FRONTLINE Plus is fast-acting and long-lasting, and it is waterproof 24 hours after application.

The reservoir-based distribution means the active treatment is not confined to the spot where it was applied. Once the 24-hour period after application has passed, getting wet does not stop it from working. Follow a monthly routine to maintain the treatment’s full 30-day period of flea and tick protection.

• Topical application is made at one point on the dog.
• Replenishment from the sebaceous glands supports coverage across the body.

Does this pack fit my dog, and how many doses are included?

This medium-dog pack is intended for dogs weighing 23–44 pounds and contains six doses. Each dose provides protection for a full 30 days, making the pack suitable for maintaining a recurring monthly treatment schedule for a dog within that weight range.

FRONTLINE Plus products can be used on puppies from eight weeks of age and weighing at least 5 pounds, but this particular medium-dog dose is for dogs in its stated 23–44-pound range. A separate FRONTLINE Plus formula is designed for cats and kittens from eight weeks old and weighing at least 1.5 pounds; this listing is the dog formula.

• Use the dog’s weight to select the appropriate FRONTLINE Plus size.
• The six-dose quantity supports six monthly applications.
