Customer Reviews

Rated 4.1 out of 5 by 803 reviewers.
Rated 5 out of 5 by Effective. I have never seen a flea or tick on my dogs and where is I live is "tick country" The only reason I didn't give it a 5 paw ease of use is because for some reason my dogs do not want to stay still for me to put it on. It doesn't hurt so I don't understand it but a treat works for cooperation. So far I have no complaints about the product - just wish it wasn't so expensive. January 21, 2016
Rated 5 out of 5 by Wonderful! Wonderful product, easy to order and quick delivery. January 12, 2016
Rated 2 out of 5 by Not working for us I've been using this product on both of my small dogs for about 6 months now. I continue to find large well fed ticks on both of them. Although the ticks are dead when I find them or when they fall off my dogs, the fact that they are able to feed to the point where they're as large as a pea tells me that something isn't working as it should. Isn't it suppose to repel the ticks before they get a chance to make a meal of my mini Schnauzer and Schnoodle? I'll be switching to another product. January 7, 2016
Rated 4 out of 5 by Advantix II works well I use it faithfully every month. I did find a tick on one dog twice throughout the summer. It does not work on deer or horse biting flies. January 1, 2016
Rated 5 out of 5 by This product cover most bases of inscent repellent & control. Our 12 year old Yorkie has experienced NO side efects with K-9 Advantix! Unlike many of the other products available for use on small dogs. December 12, 2015
Rated 2 out of 5 by No what it used to be This product used to work great but no longer has the effectiveness that it used to have. November 22, 2015
Rated 2 out of 5 by My small dog had a skin reaction. Large dog tolerated it fine . I will need to go back to Advantage. I thought I was ordering my usual meds for my 2dogs. The price was very good and shipped in a timely fashion. However, after applying Advantix II on both dogs we noticed later in evening our Shih Tzu was very restless , could not relax , began to scratch . Our Lab was fine. I realized Advantage was what I usually ordered so I called the number on the back of box and spoke with a Bayer rep. They explained it had one other ingredient than Advantage and did not go into blood stream but stayed on the skin . She gave me helpful info as to how to treat the problem and we did . However our dog was miserable for two days as were we as he could not relax to sleep for very long without a hand rubbing the area for him. NO MORE ADVANTIX! November 20, 2015
Rated 1 out of 5 by Fleas seem to be immune I have used Advantage and Advantix 2 for as many years as it has been out on my dogs and it was wonderful. This is the first year that they have had no effect at all. It was terrible for the dogs! Maybe due to the long California summer and drought conditions. I had to go to the vet to get an oral medication that seems to be working okay. October 29, 2015
