Rated 4.3 out of 5 by 531 reviewers.
Rated 5 out of 5 by Easy to use We have used K9 Advantix II for Dogs for years and we highly recommend it, our pets have not had any problems with fleas or ticks. May 23, 2016
Rated 5 out of 5 by We used to have a tick problem We live in a nature area with lots of trees, mulch, bushes, etc. and several times, we found ticks on our cocker spaniel until we started using K-9 Advantix II. Now, "There ain't no bugs on me", is the song we're singing. Also, in checking on side effects, this product seems to have less issues. May 21, 2016
Rated 1 out of 5 by Not very effective this season Last year we didn't seem to have a problem, but for some reason this year, we are getting A LOT of ticks, even 5 days after application. I don't know if it is a bad batch and maybe a particularly bad tick year, but we are going to keep trying and see if it was just a fluke. I did add a collar on for added protection, so that will confound my results, but don't want to take risks with my baby! May 16, 2016
Rated 4 out of 5 by it do what it supposed to do. Works great. been using it or 15 yrs and it has always done great. May 2, 2016
Rated 5 out of 5 by This product covers fleas ticks and mosquitos... As a first line of defense for my small dogs..I prefer this product over most others. The pricing, packaging and quick delivery makes it easy to be a loyal customer.. May 2, 2016
Rated 1 out of 5 by 2 weeks later, still scratching, no dead ticks Absolutely ineffective. My dog got chewing lice and this made no change whatsoever in treating them. In addition, it definitely does not kill ticks. Poisoned my dog with this stuff and didn't even result in what was promised. May 1, 2016
Rated 5 out of 5 by I've used Advantix for many years and will continue to do so. My Veterinarian recommends this product, so I will continue to use it for my dog as long as the Doctor thinks it appropriate. We live in a tick-infested area with lots of woods and fields with tall grasses. It is therefore necessary that we use a flea/tick preventative for our dog. I have used various collars in the past and other "liquid" products for my dogs but Advantix seems to be the best one on the market to date. May 1, 2016
Rated 5 out of 5 by excellent. never had any problem w/ insects on pet Excellent product. I've never had any problem with flees, ticks or flies. My dog is comfortable walking outside. And he gives me no problem when I apply medicine. I'll continue to use this product and recommend it to friends. Thank You May 1, 2016
