Customer Ratings & Reviews

Rated 4.5 out of 5 by 44 reviewers.
Rated 5 out of 5 by It's the good stuff! I live in rural Louisiana, Where the ticks are known to outweigh small dogs and the state bird is the Mosquito. I have used K9 Advantix and K9 Advantix II for dogs over 55lb on both Smith and Wesson, My Kelpi dogs, for the entire ten years of our relationship. I saved Ruger, my Black&Tan Hound puppy from the dumpster where some P.O.S. abandoned him, he now gets K9 Advantix over 55lb also. My most recent purchase of this product was for Saiga, a 4lb silky terrier who was abandoned or lost alongside the highway and came running when she saw me and is still here (no one responded to flyers for a lost silky) she is about the size of some of the Ticks around here. With monthly use of K9 Advantix II, I have NO Fleas or Ticks, and I breath a lot easier knowing the product is effective against the ever present flocking hoards of Mosquitos in this area.

Rated 5 out of 5 by 2nd year and going strong! I LOVE this product for my babies! Ever since starting to use this last year, I have not had any problems with fleas/ticks OR mosquitoes and we live where there are PLENTY! (in the country) It goes on easy for them and they have had no adverse side effects. I will continue to buy this for them and Chewy.com has the best prices around! 2 thumbs up!!! April 14, 2015
Rated 4 out of 5 by good product I have a small dog and live in florida (a lot more fleas and tics year round) and this seems to keep the bugs away. February 17, 2015
Rated 5 out of 5 by great product This product works very well on my pomerian. It is easy to use and efficient. I will order it again in the future from chewy. February 3, 2015
Rated 5 out of 5 by This is perfect for my 6lb Pom. Chewy has fast service. This item was the least expensive that it why I chose to purchase it here. I also order my Poms food and it is always deliver the next day. Great service Chewy! January 12, 2015
Rated 1 out of 5 by It doesn't work I've used this product before and it is'nt working on my dog. I don't understand. I've bought this product from 1800 petmeds and never had this promblem!! My dog has fleas August 20, 2014
Rated 1 out of 5 by NOT WORKING IN NY I sympathize with xxxcdxxx. I live in Queens, NY and have had fleas on my dog 3 times this year, June, Sept and Oct. I have been using k9 advantix 11 monthly since March!!! The Bayer company said bathing her once a week was to often.... I don't know how to respond to that. They told me that the fleas should be dead within 12hrs which should not give them time to lay eggs or cause a 3 month flea cycle. November 20, 2013
Rated 3 out of 5 by Not working :( Unfortunately, my dogs are still biting away. Gave advantix to my three dogs and the fleas are still here. I'm think we have super fleas so I'm going to try alternative flea meds. Hopefully these meds work for other people!! July 28, 2013
