Frontline Plus Spot-On Treatment for Large Dogs 20–40kg

Frontline Plus for Large Dogs 20–40kg offers trusted, long-lasting protection against fleas, ticks, and lice. This monthly spot-on treatment is easy to apply and delivers powerful results, killing adult fleas on your dog and eliminating flea eggs and larvae in the environment to stop the flea life cycle in its tracks.

Formulated with Fipronil and S-methoprene, Frontline Plus targets both adult parasites and immature flea stages. Fipronil disrupts the nervous system of fleas and ticks, while S-methoprene inhibits flea egg and larval development. After application, you may notice increased flea activity as the product begins working—this is due to the hyperactivity Fipronil causes before fleas die.

This treatment also combats flea allergy dermatitis and biting lice, both common issues in dogs. For paralysis tick protection, apply every two weeks; for brown dog tick and flea protection, apply monthly. Its waterproof formula remains effective even after swimming or bathing, making it ideal for active or outdoor dogs.

Suitable for use on puppies from 8 weeks of age, as well as breeding, pregnant, or lactating females.

How It Works

Fipronil kills adult fleas and ticks by disrupting their nervous system, while S-methoprene prevents flea eggs and larvae from developing into adults. This dual-action formula breaks the flea life cycle and provides effective tick control.
