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.

does this product have a citrusy smell??
Answer by ChewySep 18, 2019
This product does not have any added scent.

is this product water proof ?
Answer by ChewyFeb 15, 2023
Advantage II for Dogs is waterproof after 24 hours. There is no need to reapply the product after weekly swimming or a bath. For best results, it is recommended to use a non-detergent shampoo.

Does this kill or repel ticks
Answer by ChewyOct 20, 2021
This treatment does not kill ticks. It kills all life stages of fleas and treats, prevents, and controls lice infestations.

Will this be effective for a dog already infested?
Answer by ChewyJun 28, 2021
This spot treatment can be used for a current infestation or as a preventative. It will begin working within 12 hours to kill fleas on contact.

Awesome stuff

I have used this for years and it is by far the only product that actually stops fleas. Please disregard bad reviews. If you read them, it is almost always that people didn't follow the directions or that they expected this product to do things it isn't meant to do. It is not for ticks or heartworm. It is only meant for fleas. No baths or swimming for 3 days prior to, or 3 days after application. I've seen advantage wipe out and completely halt severe flea infestations on rescue dogs, quickly and with no ill effects. Definitely worth the few dollars a month and chewy is super reliable for fast delivery and the lowest price!

Advantage II is a great product. Some people don't like to give their dogs this type of flea product but we've been using it for years and we've never had any issues w/ fleas. And our 2 dogs have not had any adverse reactions to it. With 2 dogs, the 6 doses in the package saves us a lot of money.

Advantage II

Works excellent for approximately 3 weeks. Then I usually find a few fleas and need to reapply around that timeline.
