FRONTLINE Plus Flea and Tick Treatment for Medium Dogs (23–44 lbs) – 6

FRONTLINE Plus Flea and Tick Treatment for Medium Dogs (23–44 lbs) – 6 Doses

Protect your medium-sized dog with FRONTLINE Plus, the #1 trusted brand in flea and tick protection. Designed for dogs weighing 23 to 44 pounds, this fast-acting, long-lasting topical treatment kills fleas, ticks, and chewing lice while preventing future infestations. With just one easy monthly application, your dog stays protected for a full 30 days — even after bathing or swimming.

Advanced Dual-Action Formula

FRONTLINE Plus uses two proven active ingredients — Fipronil (9.8%) and (S)-Methoprene (8.8%) — to provide complete pest control. Fipronil kills adult fleas and ticks, while (S)-Methoprene prevents flea eggs and larvae from developing, breaking the flea life cycle and stopping re-infestations before they start.

Fast-Acting, Long-Lasting, and Waterproof

This waterproof formula begins working quickly to eliminate pests and keeps protecting your dog for a full month. Once applied, the treatment spreads through your pet’s natural oils and stores in the sebaceous glands, providing continuous release — even after exposure to water, rain, or bathing.

Easy Monthly Application

Applying FRONTLINE Plus is simple and stress-free:

Remove one applicator from the blister pack.
Open by snapping off the tip.
Apply directly onto your dog’s skin between the shoulder blades.

Use once every 30 days for consistent protection. Do not use on dogs under 8 weeks of age or weighing less than 23 lbs.
