Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 90 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

What would happen if I give my dog who is slightly under the weight limit the same amount as my dog who is slightly over the weight limit? I don't want anything to happen to her but I'd much rather just split the 6 month pack between them as I've never used this brand before.
Answer by ChewyDec 05, 2017
You may be slightly under or over as long as your dog is within 5 pounds of the limit. If not, we recommend going with the next size.

How does it protect your dog when you only apply by the back of the neck
Answer by ChewyNov 21, 2017
Once FRONTLINE Plus is applied, it stores itself in the oil glands in your pet's skin. It then self-distributes continuously for one month to your pet's hair and skin through the hair follicles, killing fleas and ticks.

Can this be taken by a dog that also takes a heart worm pill with flea prevention in it?
Answer by ChewyJun 09, 2021
We encourage speaking with your Veterinarian before combining flea and tick preventatives, for the safest opinion.

What type of ticks is Frontline effective on? As there are 6 different types of ticks in my area and not all Tropicals cover all 6.
Answer by ChewyJun 11, 2019
Frontline Plus treats against Lone Star Ticks, American Dog Ticks, Deer Ticks, Brown Dog Ticks, and Western Blacklegged Ticks.

Doesn't work after several months

My dog hasn't ever had fleas before. We switched from K-9 Advantix to Frontline, and I understand it takes a few months to fully adjust but I have been applying Frontline as directed for months now and I don't see that it is working. For the first time, my dog got fleas and it doesn't seem like this topical medication helps at all. It may work for others, but it definitely didn't work for us which is a disappointment after spending a lot due to other's great reviews.

Don’t buy. Not worth your time and money.

You’re better off going outside, lighting your money on fire and watching it burn. That will be more pleasurable than buying and waiting for a FLEA TREATMENT that absolutely does not kill or repel fleas. If you decide to purchase you will be left with time wasted calling these companies, all while the fleas do the boogie on your pets. And the money is spent to the companies and out of your pocket. Duped. Purchase something better, probably from the veterinarian, I’m going to have to. Good luck.

Love this product!

I feel comfortable using frontline plus for dogs on our family golden retriever. There has never been any issues whatsoever with ticks, fleas, etc. This stuff seems to have always worked. Our family definitely has seen ticks in our backyard but this stuff has always protected out dog against the insect. Works for us! I also use the frontline plus for cats on our kitty with no issue.

Seems to work, but dog hates it.

I've used Frontlline for many years on different dogs, and it works, as I've never noticed any fleas, ticks or other nasty critters on my dogs after using it regularly. That being said, all my dogs hated having it applied. And I mean HATE. They would hide when I brought it out of the closet, and attempt to rub it off afterwards by rubbing along the side of the couch, the carpet, or rolling in the grass outside in an effort to get it off. I don't know why. With my current dog, because of my experience with previous dogs disliking the product, I started using an oral product instead, but it was so expensive, and required a prescription, so I went back to Frontline again. It works, but like my other dogs, she hates it being applied to her skin. Maybe it's the smell, maybe the feeling of cold liquid on her back? I don't know what's the big deal, it's only a few drops. Anyway, this is the fourth dog I've had that has hated it.

doesn't work

My poor dog has never had fleas prior to using frontline plus, I called the hotline and they said it takes 3 months to totally work. It's now been 4 months and I'm still finding random fleas on my dog. I'm changing to a different brand

Works Great!

I've used this product for years on and off. Pets showed signs of fleas for 1st time in long while and I was happy to see frontline was available! Found dead fleas w/in 24 hours & scratching stopped w/in 2 days.

Great flea and tick prevention

Seems to work really well, and the oily spot at the application spot went away after a day. My dog didn't even know what happened and it did not seem to cause her any discomfort.

Absolute Gem

Works incredibly well. Noticed a tick on my dog two days after applying, and it was DEAD. Used this product for a considerable amount of time. Never going to switch as long as the formula stays the same!
