About FRONTLINE Shield for Dogs

The #1 Name in Flea and Tick Protection*

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.

Protect Your Dog So You Can Go Anywhere Together

Fleas and ticks can be found everywhere outdoors—the park, the lake, even your own backyard. That’s why monthly protection is so important.

From the #1 Name

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

Repellency Power

Repels ticks, mosquitos and stable flies, so they won’t bug your pet.

Kills Fleas and Ticks

FRONTLINE Shield kills fleas, ticks and chewing lice.

Powerful Defense

Repels ticks that can carry Lyme disease and mosquitoes that may transmit heartworm disease.

Trusted Protection

FRONTLINE brand products are the flea and tick protection products pet parents trust most.*

Waterproof

FRONTLINE Shield becomes waterproof 24 hours after application, for lasting protection.

Effective for Puppies

Can be used on puppies as young as 9 weeks old who weigh at least 5 lbs.

For Dogs Big and Small

Doses come in Extra-Small 5-10 lbs., Small 11-20 lbs., Medium 21-40 lbs., Large 41-80 lbs., and Extra-Large 81-120 lbs.

Fleas and Ticks Abound Year-Round

No matter the time of year, fleas and ticks can pose a threat to your dog. Flea infestations usually begin 6-8 weeks before you ever see a flea, and once you have a flea problem, it can take 90 days or more to fully eradicate. That’s why you need monthly protection year-round with FRONTLINE Shield.

Does Not Work

Do not I repeat please do not use this new and improved protection. My dog almost died because she was bitten by a tick and got Lymes disease

Works great!

It's been a while since I've had a dog and wasn't sure which flea & tick prevention to use on my puppy. I did my research on Chewy and decided to give Frontline Shield a try. Fleas & ticks gross me out so I wanted to be sure and get him started when he was old enough and keep up with it every month. So far so good! Also like that it helps with mosquitoes - I don't like them biting me so it makes sense he wouldn't either!

Great flea and tick product

My dog Lucky loves being outside. We live in an area with A LOT of mosquitoes so I'm glad I found a product that kills fleas and ticks AND repels mosquitoes! Now Lucky can play outside and I don't have to worry.

Dog seems happy

I'm not expert but the dog seems happy and I haven't spotted as many fleas and ticks as in past summers so that's a win for me. I love the applicators because they are easy to use.

Flea meds don’t work

This flea medicine doesn’t seem to work. My dogs are still scratching and seem very uncomfortable. I won’t be purchasing this brand anymore.

Dogs still have fleas!!! Thought this was a stronger better Frontline. Very disappointed in this product.

Great product!

I was apprehensive to use a topical flea and tick product. But here in Fl it is a year around problem and I have tried shampoo’s, sprays, over the counter products and none worked. It was either a topical or a pill. This works great!
