Is Frontline working for fleas?

Dr. Marie replied:

It sounds like you are doing the right things. One thing to know about fleas is that you will not be able to cure the problem instantly. When a dog has fleas, there will be flea eggs in your house. While vacuuming will help, it's not going to completely get rid of the fleas.

As the flea eggs hatch, they are amazing at seeking out a cat or dog to jump on. They can only reproduce if they get a blood meal from a cat or a dog. So, you need to keep treating monthly. Sometimes we can get rid of a problem in 3 months, but sometimes it can take 6. You need to be sure that every animal in the house is treated with a prescription product each month.

There are some parts of the world where Frontline is not working as well as it used to. I can't speak from experience because I practice in Canada where we do not have Frontline. But, you could ask your vet's opinion on the efficacy of Frontline in your area. If it is not working well, then you could switch to a product such as Comfortis, Revolution, Trifexis or Advantage.
