FRONTLINE Plus for Dogs – Flea & Tick Protection for Medium Dogs (23-44 lb) 8 Treatments

Overview

Protect your canine companion with FRONTLINE Plus for Dogs, a fast-acting, waterproof topical designed to guard against fleas and ticks for a full 30 days. This formula targets fleas at multiple life stages—adult fleas, eggs, and larvae—and also tackles chewing lice and ticks that can transmit Lyme disease. By combining fipronil with (S)-methoprene, it helps disrupt the flea life cycle and reduces the risk of reinfestation, all while delivering continuous protection between applications.

With a history of use spanning over two decades, FRONTLINE Plus is trusted by many pet owners. It supports daily life, including outings, play, and baths, because the medication is deposited in the skin’s sebaceous glands and released gradually over time. A single monthly dose provides protection for an entire month, and the treatment remains effective even if your dog gets wet or dirty.

How it works

The active ingredients travel through the oil glands on your dog’s skin, creating a reservoir that replenishes the protective coating as needed. This means protection is available across the entire body, including hard-to-reach areas, with just one application per month.

• Kills fleas, flea eggs, flea larvae, chewing lice, and ticks that can transmit Lyme disease
• Breaks the flea life cycle to guard against reinfestations
• Waterproof and long-lasting, with monthly dosing

Usage and safety notes

FRONTLINE Plus for Dogs is formulated for puppies as young as eight weeks old and weighing 5 pounds or more. It is designed for single-point application that covers the entire body, helping you manage flea and tick protection with ease. The product is designed for use on dogs, with a separate formula available for cats and kittens eight weeks and older.

Who can use it and lifestyle considerations

Ideal for households with one or more dogs, FRONTLINE Plus can be used on dogs that spend time outdoors, in wet environments, or during seasonal flea and tick activity. For pet parents who want ongoing protection, subscribing can simplify dosing and help ensure protection stays year-round.
