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.

Questions & Answers

7 Customer Questions

my two dogs are 183 and 175 lbs. should 2 of the treatments be used each month due to their size?

Answer by Chewy • Feb 11, 2019
It's not recommended to use this flea treatment on dog weighing more than 132 pounds.

What is the difference between the Plus and the the Gold?

Answer by Chewy • Apr 07, 2019
FRONTLINE Gold is the latest innovation in flea and tick protection from the maker of FRONTLINE Plus. In addition to having fipronil and (S)-methoprene, they now added a powerful third ingredient, pyriproxyfen which helps to kill the next generation of flea eggs and larvae before they can develop in to adult fleas.

Is this product safe for pregnant and lactating dog?

Answer by Chewy • Feb 17, 2019
Frontline Gold is approved for use on dogs who are breeding, pregnant or lactating.

what does pyriproxyfen do?

Answer by Chewy • Dec 17, 2018
Pyriproxyfen mimics a natural hormone in insects and disrupts their growth.

Decided to try this because Fig is a swissy (epileptic prone breed) and the ingredients were safer. The first night when we used this, she did have diarrhea (gastro upset is part of a side effect) but the second time we applied it, she was normal with no tummy upset. She's going on her third month now and we've had no fleas or ticks. We live in Boston, and mainly explore the city parks but this past weekend we went to rural parts of Vermont, New Hampshire and Mass and I for sure thought she was going to pick up ticks but she didn't! I double downed on prevention and did pair it with wondercide spray on one of the hikes, but to see if the ointment worked I didn't apply the wondercide to two other hiking areas and she didn't pick up ticks. So far so good and seems like its working! :)

Fleas and ticks stay gone!

I live in the Ozarks, where scientists from around the world come to study ticks, Lyme disease, etc. because every species of tick known to man lives here. But

Works great

Fleas in Florida can be hard to control. The Frontline works great on my Great Dane and Labrador.
