Is Frontline still effective against fleas?

[KMaC]

My dog has fleas. Put Fronline on her October 31st and was still finding fleas every day. I gave her a bath today and was very surprised that I got about 50 fleas off her. I spoke to 3 people who all said Frontline wasn't killing their dogs' fleas either. Is it possible that fleas have evolved to become immune to Frontline? Given the price of Frontline I expected better results.

We are having the same problem here. Dosed all of the Cats & Dogs around the same time as you. Before, when we dosed them, the fleas were gone within a week or so. This time, it's been over 2 weeks and still having flea issues..

Wonder if they have changed the formula or something??

Where did you get it? Was it online? Significantly cheaper than usual?

Ive found the Chinese knockoff market is infiltrating EVERYWHERE so if you found a helluva deal, you may have been taken.

Nope. Got it from the vet with rebate from manufacturer so I know its real.

Think it's just a bad year for fleas. Heard a lot of petowners complaining.

If you check online you will see quite a few articles suggesting that fleas have developed immunity to the active ingredients in Frontline. There is quite a bit of dancing around the issues by professionals (vets) because I gather Bayer and Sanofi's lawyers are quite aggressive about disputing such claims

Here in Central Ohio we had to switch away from Frontline two years ago because it just wasn't effective. We have had and are still having good luck with Vectra 3D, which is also topical. I personally would not put a dog on systemic treatments unless there was just no other choice. I'd go back to regular pyrethrin shampoos first

My vet told me a year or so ago that if you don't switch up every so often, the colony of fleas will get immune to whatever you're using. We switched to a chewable tablet treatment (cannot for the life of me remember the name) at that time, and fleas have been almost non existent this year.

We give our dog Trifexis (heartworm, flea and intestinal worm preventative) plus a topical (Pet Armor usually), so the fleas get a double whammy.

Well great, I paid $80 for 6 doses and still have 4 left. I guess I'm going to have expensive trash this week.

I'd hang onto it and just use something else for awhile.
Our two "inherited " lab mutts ( who, by the way, are still up for adoption, ) are allergic to fleas and the usual treatment of front line or advantage didn't work.
The Redkey vet gave them some rather expensive comfortis, and it seems to be doing the job.
As advised above, I think we're going to have to switch it up occasionally.

I have been using the Seresto collar for the last 8 months and have had no more flea problems

Bayer advance, use at your own risk.

We have a GoldenDoodle that we give the Frontline topical and he had fleas at his last hair appointment. The groomer said to switch to Advantage and see if it helped. So December he gets Advantage. We have a truck ton of critters in our yard, squirrels, rabbits, raccoons, opossums, and chipmunks. I can't wait for the hard frost to kill these things off. I have even talked to my yard spraying guy about treating my yard next year for pests. It has been a never ending battle. -Jason

House and yard need to be treated to win the flea war, dogs also get worms from swallowing fleas.

We had that issue with frontline. We've used simparica for the last few seasons with good results. It is a chewable tablet.

 

[caverjamie]

Had same problem with Frontline. Vet had us use something called Revolution, it did the trick...

 

[gopher]

Our vet prescribed Capstar and NexGuard for our Standard Poodle (don't laugh, they are great dogs). He also said that this has been a bad year for fleas...

 

[bobbittle]

I started using the new flea collar made by Bayer, good for 8 months for $30ish per collar. No issues since switching.

 

[KMaC]

I didn't realize there were so many different products for fleas. Guess I better start studying for a replacement. 20 years ago they were claiming that flea collars were too toxic and killing dogs. Has there been any complaints about the new flea collars?

 

[johntheplinker]

Yes, you have to switch on a regular basis. We use Frontline, Advantage, Revolution and Vectra in rotation and have had little problems with fleas this year. Except when we went a week too long and in that short time the little bastidges got horrible. Seemed like it took 2 months to get everything back under control. You may also want to use a spray that contains a insect growth regulator on your pet's bedding, carpets, and upholstery so the pests won't mature and reproduce.

Good thing about Revolution is it also takes care of some types of worms.
