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.

The high price of them, that really made me happy!

They arrived in short time and each pill is individually wrapped, what a nice touch. It was so easy picking one out instead of having to pour one out of a bottl

I have been using Frontline on all my Dogs for years and years. I live in the country with ticks galore. I have to pick them off my horses but never my Dog's. What I like most is I am not feeding my dog a poison to kill ticks. I like that it is a topical medicine. I tried the internal medicine and it made my precious dog sick. So I am sticking with what has worked for years. Just wish it was not so expensive.

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.

Kills some fleas, but fleas are still jumping around everywhere and carrying disease and parasites we do not want or need to get to us or our animals. Last box was 110% ineffective and leaking, then was sent another box, and it immediately started working, just killed about half the fleas, but half the invasion is still left. But we LOVE our CHEWY!!

Frontline Gold

Frontline Gold has worked great for us! Sadly, I’ve read that it’s no longer being produced and we will need to switch to something else.

ineffective and NOT veterinarian recommended

this proved ineffective on my dogs. My Vet said these topicals are rarely effective on large thick coat dogs.
