How often do I apply Frontline Plus?

One dose per month gives about 30 days of flea and tick protection. Treat every dog and cat in the household on the same schedule to control fleas in the home.

Can I bathe my dog after applying it?

Yes. It is waterproof and stays effective after bathing, swimming or rain once it has dried. Wait until the application site is dry before bathing.

How is it different from a chewable flea tablet?

Frontline Plus is a topical that spreads over the skin and also kills flea eggs and larvae, so it interrupts the life cycle. Chewables work from inside the dog and generally kill only what bites.

What age and weight can use it?

Puppies from 8 weeks old and dogs weighing at least 5 pounds. Use the cat formula on cats; never apply the dog product to a cat.

Does it repel ticks and fleas?

No. It kills fleas and ticks after they get on the dog, but it does not stop them from climbing on, so you may still see attached ticks.

Three monthly topical doses, each applied to one point on the back between the shoulder blades.

About the Boehringer Ingelheim Frontline Plus Flea and Tick Treatment for Dogs, 3 Doses

Frontline Plus for Dogs is a monthly topical flea and tick treatment. It kills adult fleas, flea eggs, flea larvae, chewing lice and ticks. It kills all stages of brown dog ticks, American dog ticks, lone star ticks and deer ticks, which may carry Lyme disease.

The formula contains fipronil and (S)-methoprene. It kills existing adult fleas, eggs and larvae, which breaks the flea life cycle and helps prevent new infestations. It is a non-systemic spot-on that acts on contact, not through the blood.

Apply it to a single point on the dog. The treatment spreads over the entire body and collects in the sebaceous glands, which slowly replenish it onto the coat. One dose each month protects against fleas and ticks for 30 days. It stays effective after bathing, water immersion or exposure to sunlight. It can be used on puppies at least eight weeks old that weigh 5 pounds or more.
