Customer Ratings & Reviews

Rated 4.7 out of 5 by 36 reviewers.
Rated 5 out of 5 by Works fast I have used this product in the past and liked it but unfortunately my vet quit selling this brand. Most years when my dog got fleas a few baths would control the problem but this year the fleas seemed to explode. My dog was so uncomfortable I sat and cried because the other treatments I bought didn't work after the first treatment, the second treatment 11 days later and then the third. Finally I received this product within a day of ordering , treated my dog and now she can rest and enjoy life without all the scratching. I've tried many others for her but none gave results like this. We are all much happier and HEALTHIER September 30, 2013
Rated 5 out of 5 by Best thing on the market This is the best flea/tick product without heartworm prevention on the market. Miles ahead of K9 Advantix and Frontline. Is effective from Maryland to California to South Carolina - all climates! December 15, 2013
Rated 5 out of 5 by best flea treatment on the market. and I have tried them all best flea treatment on the market. and I have tried then all April 9, 2014
Rated 5 out of 5 by Really works well We have 5 dogs ranging in size from a 100 pound lab to a 6 pound chihuahua and 3 cats all rescues. I have alternated between Advantage and Frontline. I have found that Advantage is far superior to Frontline especially recently. Chewy has the best prices, especially with their sale. June 21, 2014
Rated 5 out of 5 by Goodbye to the fleas! I purchased the large dog package because I have a large dog, a small dog, and an ornery cat. I was able to split the correct doseage and give them all a treatment. Doseage chart can be found on the internet. Haven't seen any fleas. Yeah! Oh, but be careful that the product you choose is safe for cats too. May 7, 2015
Rated 5 out of 5 by Advantage gets rid of fleas I've found that AdvantageII works! I've used AdvantageII on my dogs, as well as cats, several times a year, for years, and have never had a flea problem. I like ordering from chewy because their prices are cheaper than any others I've found and the product is delivered right to my door in just a few days. October 4, 2014
Rated 5 out of 5 by This is the only product that kills without biting! I love this product because it kills the flea in all cycles of its life, so I don't have to worry about infestation of my home. But the BEST part is, the flea doesn't have to bite to die. All other products work after the flea has bitten your pet. If you have a pet with a flea allergy like me, that is torture to an animal. This is the only way to go! August 7, 2014
Rated 5 out of 5 by Easy to use and effective Upon receiving this product, I followed the instructions, applied Advantage II to my 110 lb. rescued pitbull/mix, Blue and within 2 hours he stopped scratching and biting and almost 3 weeks later is "Flea Free". Best pet product I have ever used. April 18, 2015
