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.

I've been using Frontline on my dogs for 37 years

I've been using Frontline on my dogs for 37 years. Why? Because it works. In all that time we've never had a flea infestation or a tick problem with any of our Doberman Pinschers. That seems like a good track record to me. This year, however, for the first time, our new rescue Dobie has had a terrible time with fleas. It doesn't surprise us because the change in the climate has affected everything in our household, from the dogs to our rose garden toe our vegetable gardens. Things are simply burning up. Our roses crumble like potato chips and on 8 tomato plants we have harvested 6 tomatoes! Usually, we have so many tomatoes we have to give them away, and the same with the roses. But with the intense heat, and, I believe, the thinning of the ozone layer, the sun feels so much hotter and seems to be burning everything up--including us--like it has never done before. We thought perhaps our Dobie had developed a tolerance for the Frontline, so we tried another brand of flea treatment and it made no difference. Now we're back to Frontline and we'll stick with it. After 37 flealess years, I think we'd be foolish to start experimenting now. As the cliche goes, "If it ain't broke, don't try to fix it."

Never Again

My 12 year dog now has fleas and she is miserable. Was recently told by our veterinary clinic to not use Frontline, as it absolutely worthless. Very disappointed in the amount of money wasted on this product and the amount of money it is costing to rectify it.

yes it works

20+ year frontline user here, yes this works. I apply frontline once a month in different spots all over my dog, I have no idea what the actual instructions say but I really don’t care, I put it everywhere and it works. Put it on their head, tail, neck, hips, etc. you also need to understand your dog CAN NOT get wet for 3 days, that means no jumping in a pond, no bathes, no sprinkler time, no water on their body at all. Do this and a tick might crawl on them but it will immediately die. We live on a farm and this is all we have used for 20+ years of dogs, one of which lived to be 19. It’s one of the oldest and most studied tick treatments on the market and made in Germany, I only trust this brand.

Waste of Money DOESN'T WORK!!!

If I could give this product 0 stars, I would. My dogs have fleas so I thought this would be a good solution to our problem. IT DIDN'T WORK AT ALL. I gave them 2 applications, 2 weeks apart because the first application did nothing. The 2nd application was just as useless. I went to my vet and he told me that Frontline hasn't worked on fleas in years!!!! It may be affective for ticks but NOT FLEAS!! I spent $175 on Frontline Flea Treatment for my dogs and cats (DIDN'T WORK ON THE CATS EITHER), and it was a COMPLETE WASTE OF MONEY. The fact that Chewy sells this product as a flea treatment makes me question their integrity as a business. DO NOT BUY THIS PRODUCT. IT'S A WASTE OF TIME AND MONEY!!

$$$ overpriced

I don't know how I didn't realize I paid double the price for Frontline at Chewys until now. It's my fault I didn't pay more attention but I'm severely upset with myself that I got charged the same price for a topical solution when I could of got NexGard for the same price. Frontline is easily 40.00 everwhere-not 70 dollars!! I hate using topical solutions and even though it has worked I feel it's not worth paying the price Chewy is selling it for. I recommend the chewable kind over topical - if at this pricepoint for sure.

Missing half the product

They really sent me an open box of Frontline with half of it missing. Maybe it was because I finally decided to try the autoship option. But in the past this product has worked wonders for my dogs.

No longer seems to work.

Our household has used Frontline for our dogs for a long time on the regular, monthly schedule. Lately, it does not seem to be working as we keep finding fleas on our dog. Very disappointing, we will be changing our flea preventative and treatment.

Frontline Flea & Tick

I don't like to apply chemicals or have my dog ingest a pesticide and go into her bloodstream, so I opt for Frontline (absorbed by oil glands and effective prevention of fleas and ticks for large dogs for 1 month). No adverse effects/waterproof. I don't use this regularly, and my dogs have never had bugs, thankfully. I had to order in a rush when I was travelling, as my friend thought she saw a tick on my dog's paw. Chewy are so fab, they delivered the items in less than 24 hours! My friend lives in a wooded area so it's possible the risk of deer ticks is higher, but I was more impressed with Chewy delivering to my friend so quickly! I love this company and the staff - don't ever change as you have customers for life! Thank you so very much!

Works for us

Living in North Carolina fleas and ticks are a year-round issue. I had used frontline successfully in the past and then switched to a Seresto collar. My dog did fine with his first Seresto but seemed irritated by the second one so I went back to frontline. I will continue to use it unless it lessens in effectiveness after time (which is why I switched to the collar in the first place.) But it took years before frontline seemed less effective. It's a good solution to fleas and ticks.

Frontline Did Not Work!

We treated our dog the first of the month. By the third week he was scratching and I gave him a bath to find six fleas in the water. We treated him again and he never stopped scratching. A neighbor told me that her vet said fleas have become immune to Frontline. I believe it!
