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

11 Customer Questions

We have a very small puppy, weighs 3 lbs at 3 months. This product says 4 lbs, and up. Can we use this or is there another product for those puppies under 4 lbs?
Answer by ChewyMar 13, 2018
This treatment can be used on dogs and puppies 7 weeks and older and weighing 3 to 10 pounds.

My puppy is 9 weeks but her weight is only 1,9 lbs. Can she use this product?
Answer by ChewyJul 21, 2020
For dog's weighing under 3 pounds, we recommend consulting with your vet to determine the safest dosage amount.

Do I need a script from a vet to purchase?
Answer by ChewySep 19, 2017
We wouldn't need a prescription from your vet for purchase.

Is it ok to bathe my puppy before applying this flea medicine?
Answer by ChewyJun 12, 2022
You can bathe your dog before applying Advantage II. Just make sure your dog is thoroughly towel-dried before application. If you choose to bathe your dog in between treatments, it is recommended using a general grooming shampoo for pets. Keep in mind that more frequent bathing may keep the product from working the full 30 days.

Great product!

Great product! Works fast and lasts long! My dog had gotten quite a few fleas and this worked quickly and effectively. We use it monthly now and have no problem with fleas anymore!

Helped my puppy

This product helped minimally to some extent. It can only be applied once a month, 4 applications in 1 box. Hoping it would do better as the months progresses.

Not as good as Advantix

This product does not provide the protection that Advantix II provides. Would not recommend.

On Sept 23, 21 I ordered Advantage II Flea Spot Treatment for Dogs 3-10 lbs that has 4 doses for 4 months. I opened the 1st dose that is a very tiny tube to apply the gel to my Chihuahua, only 1/3 of a small drop came out, I didn't think it's enough so I opened the 2nd dose, nothing came out shockingly. I opened the 3rd dose, it again produced may be 1/4 of a drop. I continue to open the 4th dose, again completely empty. I don't think all 4 doses produce enough gel to help my Chihuahua's flea problem effectively. There is no Expiration Date on the box so I have no idea how long Chewy got this Advantage II product in stock. If you want this product, make sure you check the Expiration Date with Chewy C/S prior to buying it

Bad batch maybe

Have used advantage before, and Im not sure if this round was improperly stored or maybe it was expired but after the application on all my dogs (my order had 2 different weight ranges) none of the fleas were taken care of

Didn't work this time

I usually have good luck with this but this time I put it on my dogs and they all had fleas again a week later. I feel that this time was a waste of money.
