Rated 5 out of 5 by This product works well I've used this product on my pet for many years. This is better than any other flea & tick on the market today. I won't use anything else. July 25, 2015
Rated 1 out of 5 by what has happened to this product! I have spent hundreds of dollars using advantix for many years. I'm so disappointed it is not working. It would be so nice if I could at least contact Bayer on line. I have purchased different product to try. If you can't trust Bayer..... July 24, 2015
Rated 1 out of 5 by This product does NOT work I've been using this product, and it does not work. In fact it seems like it attracts fleas. I just can't grt rid of them. Don't waste your money! July 18, 2015
Rated 5 out of 5 by Great product! This works wonders for my dog who also has a flea allergy. He does not have any more issues at all once I used this products. No fleas, no scratching! Highly recommended! July 17, 2015
Rated 5 out of 5 by Easy to use, effective, doing what is supposed to do, and no major side effects We have used other products, some caused adverse reactions others were ok but seemed to lose their effectiveness. We switched to Advantix II and have had good results. July 15, 2015
Rated 1 out of 5 by fleas still on dog Does not kill fleas .worthless. used a week ago. :took 20fleasmoffmdog just in one morning. Wow. What a disappointing product. July 15, 2015
Rated 3 out of 5 by This product works well for flea prevention I have used this product for some time. It works very well at preventing fleas but my dogs still get ticks from time to time. Since I treat the dogs once a month, I should not have to worry about ticks....I lost one of my dogs some time back from ehrlichia due to a tick bite. This has made me fearful of ticks. July 13, 2015
