A while ago I wrote a post about Frontline and the fact that many people aren’t finding it effective. My suggestion was that it was a good idea to check that the product was being used properly. Since writing that post I’ve had an increasing number of emails and comments from people who are using Frontline properly, and have been doing so for many years, but who now find that it isn’t doing the job.
My own experience with Frontline has been mixed. I’ve used it on my dog in the past and it has been fine. However, when we did our usual thing of leaving off the flea treatment for the winter and due to the mild winter, she got fleas, Frontline didn’t shift them (nor did Stronghold). My sister-in-law reports that Frontline is no longer working for her cats and that her neighbours are experiencing the same thing. I have a contact who is a dog trainer in the US and she reports that her network of colleagues across the US say that the product is now ineffective in many areas (though not all). If you check the comments on my original post, you will see that a vet has commented that she believes that fleas have become immune to Frontline. I’ve also asked the question “Is Frontline working” on one of my social networks and the response I’ve got is almost unanimously “no”.
So, it looks like there is a problem that goes beyond a failure to follow instructions on using the product. It’s interesting that vets are still selling the product when so many people are reporting problems. I wondered if the vets, and indeed the manufacturer, are aware of people’s misgivings. I decided to find out; I emailed Merial, the company which manufactures Frontline, and passed on the information that’s come into me and asked for their comments. They were super quick at acknowledging the email and, I hope, I will be able to give you their take on what’s going on with Frontline soon.
I’ll keep you posted – in the meantime, keep those emails and comments coming, and many thanks to those of you who have taken the time to write to me.
