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 90 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.

My poodle has been on Frontline Plus monthly since she was 2 months old. Today at 10 months she has tested positive for Lyme disease and will need to be treated with antibiotics for a month. This could have canceled her surgery today as Lyme can affect platelets, but thankfully did not in her case. Cannot recommend.
This is the second time I received frontline from Chewy where the box holding the medicine was already open. Not ordering from them again. Who knows what someone might have switched the medicine for. I have had other companies tell me they no longer sell this because someone tampered with their medicine. I thought Chewy would be more careful with their products. Guess not
I have two dogs, thought I would try it out. I have used three months supply for both of them and yet I continue to find fleas crawling in their white fur. Would not recommend.
We live in a tick infested area of the country. Product is easy to apply and repels ticks in my dog who spends a lot of time outdoors. While we find an occasional tick crawling on his fur after hikes in the woods, the ticks do not attach to our dog. Very happy with this product!
We have used this product for years. No adverse effects on our dog with no fleas or ticks. Works well.
Love everything about this- no ticks, easy to apply, dries quick, doesn't smell. Chewy.com pharmacy worked directly with my vet to get it approved, had it in days!
I had to switch to prescription, this does not work.
Best product on the market!!! Anyone complaining is obviously using it wrong. You need to be treating your dog YEAR ROUND not wait until your dog is infested. Also there is a method on how to apply DIRECTLY to the skin NOT the hair!!! Duh people come on hooked on phonics works try it.
This did absolutely nothing to stop fleas and ticks on my 40 lb Aussie. We live in an urban area where the ticks shouldn’t even be that bad and he’s never outside longer than 20-30 min at a time but I found several ticks and a few fleas on him. It hadn’t even been 3 weeks since last applying it but online it says you can reapply after 2 weeks, if needed. Three days after the second application there’s no difference. Totally worthless waste of money.
Messy to apply. My dogs have a thick undercoat so it is hard to get product directly on the skin, especially when they are squirmy puppies. Once applied, their fur acted as a sort of siphon and sucked the product to the outer coat where it stayed greasy and damp for some time. The next application I was more careful and didn’t have as much of that problem. Both times though, we still found the occasional flea. My pets weren’t actually infested but we were pre-empting. It didn’t work. The last straw was our dog-sitter finding ticks on my girl’s ears. I want my money back.
