Your medium-sized dog deserves the same level of protection as any other member of the family.

Whether your dog is a weekend trail companion or a backyard explorer, Frontline Plus keeps the pests away so the adventures never have to stop.

Dual-Action Formula That Breaks the Flea Life Cycle

Frontline Plus goes beyond surface-level protection. Its proven combination of fipronil and (S)-methoprene kills adult fleas within 12 hours and ticks within 48 hours, while also eliminating flea eggs and larvae to stop infestations before they start. The waterproof formula stays effective through baths, rain, and swimming, so your dog stays protected no matter what the day brings. One application per month is all it takes to maintain continuous, reliable coverage.

Simple Monthly Application, Six Months of Coverage

Application is quick and easy — just part the fur between your dog's shoulder blades and apply the pre-measured applicator directly to the skin. No guesswork, no mess. Each box includes 6 individual doses, giving you a full half-year supply to stay ahead of flea and tick season year-round. Trusted by veterinarians and pet owners across the US, Frontline Plus ships fast so your dog gets the protection they need without the wait.
