Customer Ratings & Reviews

Rated 4.6 out of 5 by 28 reviewers.
Rated 5 out of 5 by Knocks out the Fleas Advantage II has been very effective in getting rid of my dog's fleas, it works better than Frontline. She had a bad case of fleas and it's been knocking them out! September 4, 2014
Rated 5 out of 5 by This product works great. I find Advantage Flea Treatment the best on the market for control of fleas. I spend 6 months in Florida during the winter and 6 months back in New York for summer months. This product works equally well in both states. People in Florida are always asking me what I use as my dog never has fleas - and believe me Florida is very infested with fleas. PA Browne July 11, 2014
Rated 5 out of 5 by This one is the BEST!!! I have been using Advantage for over 5 years & it is the ONLY one that will work to kill the fleas on my little min pin!!! Alabama has very unusual climate changes all year long & none of the others have worked as well through that than this one. Would highly recommend this product over any of the competition!!!

Rated 5 out of 5 by Advantage is the way to go! I used Frontline for years and it worked great. A few months ago, it didn't work anymore. My vet said in a place like Florida, where we use flea products year round, the fleas become immune to certain products. Luckily for me and the dogs, the fleas are very susceptible to Advantage. It works really fast, and the dogs are comfortable for 4 weeks. November 24, 2014
Rated 4 out of 5 by Worked really well My rescue dog had a single little flea and had a massive allergic reaction. So I bought this and the Richards organics shampoo. This topical worked in a few Hours and his itching stopped. The redness went down between this and some cortisone. I did reapply two weeks after the first dosage as per my vet. First time using this and I will use it again. September 21, 2014
Rated 5 out of 5 by This product is great and I would recommend it to my friend and family When I got the product I put it on my dog and it started to work within at least 2-3 hrs. It takes a little longer for the full power of the medication to work, but it seems my dogs fleas are no longer. I still see my dog itching, but I believe that is because he has long hair and possible dry skin, because of the fleas. But since I have started with this product I have seen NO fleas at all. GREAT JOB!!!! August 7, 2015
Rated 5 out of 5 by Perfect for what I needed Since there is no worry about ticks at the moment, I chose this as it was the least toxic and due to a new house member who had a couple of fleas, I needed control as soon as possible. Chewy always gets their products sent out fast. All dogs were treated quickly. The dogs seemed to have no side affects from the Advantage. Of course, these flea items should be less expensive. I would bet the cost keeps some from treating the dogs in their care. August 5, 2015
Rated 5 out of 5 by Works well Living in South Texas with a small dog who is allergic to flea bites, it is extremely important that I have a product that works. I have used Advantage II for a couple of months now. When I do find a flea on her (which is rare with this product), it is either already dead or moving really slow and obviously about to die. Chewy has the best price and fast shipping! Thanks Chewy! April 25, 2015
