Customer Ratings & Reviews

Rated 4.8 out of 5 by 30 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 I use this on my cats. I divide the 40 ml vial into 5 doses of .8. It is the same as the cat flea treatment. Also, I use it, once in a while, on my large dog also. It is an excellent product. July 5, 2015
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 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
Rated 5 out of 5 by 2 Labs in Idaho Our labs get into everything, we live in the country with roaming and fenced animals. Fleas seem to be everywhere these days. I do not let the dogs get wet for a week after application and with labs the syrum does not absorb easily but it does work. In a more heavily humid climate I used to give pills but this product is perfect for Idaho. I do not use this all year long because we have freezes. December 16, 2014
