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 30 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.

I've used this product on my dog for years. It has worked very, very well until recently. My dog has been having an issue with fleas. I use a flea comb and comb out fleas and flea "dirt". I don't know if the fleas are becoming immune to this or if something else is going on. The fleas I have combed out are slowed down though, so that's good.

Used this on my dogs as instructed, and they all still got fleas which also spread to my indoor cat. Frontline Plus for cats didn’t work either because we were treating our cat as well and he still got them. Would not recommend or repurchase.

I have always had a great experience with Frontline products. I once switch on my vet’s recommendation and it was like the ticks thought she was candy (we lived in 6 acres and 2 of those were woods) switch back to Frontline and I would find the dead ticks I missed on her bed. Hands down the best for my girl.

In Delaware and SE PA, this stuff works

I prefer using topical anti-tick treatment because it repels/kills the tick before they get into the house. I have found that this product DOES NOT work on ticks

I prefer using topical anti-tick treatment because it repels/kills the tick before they get into the house. I have found that this product DOES NOT work on ticks around Ithaca, NY. Friends have told me that it does not work on Northern New Jersey ticks either. But for now, the ticks in northern Delaware and SE PA are repelled/ killed. I have 2 Labrador gun dogs who are in the fields nearly every day. I have no problems with ticks or fleas.
