FRONTLINE Shield is powerful 3-in-1 protection for dogs. It not only kills fleas and ticks—it also repels mosquitoes, ticks and stable flies. Just one dose provides protection for a full 30 days.

Breaks the Flea Life Cycle

FRONTLINE Shield kills existing adult fleas as well as flea eggs and larvae. Once applied, it rapidly spreads over the surface of your dog’s body. One application provides continuous flea and tick protection for a full month and helps prevent future infestations.

From the #1 Name

FRONTLINE is the #1 name in flea and tick protection.*

Repellency Power

Fleas and Ticks Abound Year-Round

That’s why you need monthly protection year-round with FRONTLINE Shield.

How long does this take to kill lice?
Answer by ChewySep 18, 2022
A study showed that within 12 hours, FRONTLINE® Plus for Dogs killed 100% of fleas.

Is it safe for a large breed 11 lb puppy
Answer by ChewyApr 06, 2022
This treatment can be used on dogs 9 weeks or older weighing 11 to 20 pounds.

I have a 20lb plus cat-should I get the Frontline for small dog rather than the cat version?
Answer by ChewyOct 05, 2021
This treatment is approved for use on dogs only, it is not suitable for cats.

Does my dog require a blood draw for any reason, prior to taking Frontline Shield? Thank you.
Answer by ChewyApr 09, 2021
This product does not require veterinary examination or approval, but it is recommended that you speak with your vet before starting any treatments.

Simple, worry-free protection

Simple to apply and very effective against fleas & ticks. There are a lot of mosquitoes where I live so I like the peace of mind knowing this product repels mosquitoes too. I just make sure I don’t miss a dose so my little guy is always protected!!

No Ticks after applying!

My dachshund loves the run through the woods surrounding our home which has led to a few tick removals. I have never tried Frontline Shield and was hesitant to believe the claim of killing and repelling ticks. My dachshund has not had a single tick on him since applying Frontline Shield. He has very sensitive skin and has not had any issues at the application site compared to other brands.

LOVE this product

This product works great for my dog! She loves to play outside and run in the backyard. This product not only kills fleas and ticks, it also repels mosquitoes.

Thrilled with product

I'm happy to say that I switched from another product to this and so far my dog seems really happy and no itching. Haven't seen fleas or ticks like in the past and I like that this repeals mosquitos too.

Does not work

My dogs still have fleas after flea baths to get them started, 48 hour wait to get them completely dry, and then this treatment they still have fleas.

Disappointed

I decided to give frontline a try again only to be disappointed. The dogs have more fleas on them now than before and sadly in an attempt to fix the problem, I've now used two packets in 5 weeks with no resolution.

Expensive and doesn't work

Did not work. Fleas just partied and waved flags. By the 3rd treatment, no scratching. Have to find another brand.

Doesn’t work

My poor puppy is still itchy and bitting. Doesn’t work. Also doesn’t repel mosquitoes.
