Frontline Plus FAQ

How does Frontline Plus for dogs work?

Frontline Plus for dogs contains fipronil and S-methoprene as its active ingredients. After application, the active formula spreads over the dog's skin. It is localized in the hair and in the sebaceous glands, which act as a reservoir. These glands continuously replenish the formula onto the skin and hair coat.

Fipronil kills adult fleas and ticks, whereas S-methoprene targets life stages, preventing the laying of eggs and inhibiting larval and pupal development.

How often should I apply Frontline Plus to my dog?

Frontline Plus waterproof flea treatment for dogs should be applied once every month, year-round, for continuous protection against fleas and ticks.

Can I use Frontline Plus on puppies?

This monthly flea and tick treatment for dogs is indicated for use on puppies and dogs from 8 weeks of age, weighing 5 lbs or greater.

Is Frontline Plus waterproof?

Frontline Plus is a waterproof formula. It remains effective even after bathing or water immersion. For optimum results, your dog should remain dry for 24 hours after applying Frontline Plus.

Can I use Frontline Plus for dogs on other animals?

Frontline Plus for dogs is specifically formulated and approved for use on dogs only. You should not use it on other animals.

Does my dog need flea and tick protection even in colder months?

Though the risk of fleas and ticks is reduced during the winter, it is never zero. Fleas can survive in winter by hiding in sheltered or warmer areas. Moreover, most tick species are also prevalent throughout the year. Therefore, skipping treatments during winter may lead to infestations or diseases.

Can I use Frontline Plus on a pregnant dog?

When used according to the label, Frontline Plus is typically considered acceptable for use in breeding, pregnant, and lactating dogs when administered as indicated. However, you should talk to a vet before using any treatment on a pregnant dog.

Can I use Frontline Plus on any breed of dog?

Generally, Frontline Plus is considered acceptable for use in most dog breeds. However, some dogs may have different sensitivities. Therefore, you should consider your dog's sensitivities when using any treatment. If you are concerned about your dog's sensitivity, consult a vet before using it.

Can my dog get wet right after applying Frontline Plus?

Your dog should be dry at the time of application and should remain dry for 24 hours after application.

Can I use Frontline Plus for Dogs with other treatments?

You should use Frontline Plus for dogs with other treatments with caution, only under the guidance of a veterinarian. Consult a vet before combining it with other veterinary treatments, such as steroids, antibiotics, anesthetics, antihistamines, NSAIDs, or other topical treatments.
