Rated 4.7 out of 5 by 287 reviewers.
Rated 5 out of 5 by Works Great on Fleas We live in an area that is riddled with fleas due to the grass at parks not being treated. We had been able to keep fleas under control with a flea collar and home/bedding spray until we got new neighbors with four untreated dogs (we share common areas with them). My poor Queensland was scratching himself bald and bloody in places. I applied the first treatment of K9 Advantix around 6 in the evening after work, and by 11am the next day I found zero fleas on him when using a flea comb. The application was easy and the spots I applied it to did not have residue for more than a few hours. I'm not sure how this works on ticks as I haven't taken him to an area in which those are an issue as of yet, but the product is super effective on fleas. Our dog is much more comfortable and I am grateful. September 4, 2016
Rated 5 out of 5 by Its never failed Our dog is 17, and I've been using K9 Advantix on her all these years. She spends a lot of time outdoors, mostly laying in the sun and grass, now. I've never had a flea problem, this product does the job. September 21, 2016
Rated 5 out of 5 by this product is exellent for my Shitzu I use K9 Adventix II for many Years and find it the best Flea&Tick treatment on the Market,I used others bevor with less results. September 13, 2016
Rated 4 out of 5 by Good Stuff My dog (Ozzy) had a serious flea infection and could not get any sleep - which meant I was not getting any sleep. In the past I would take him to the vet and get an oral flea treatment which worked OK and was expensive. This year I tried K9 Advantix II Flea & Tick Treatment supplied by Chewy. The service was quick and the price was competitive. We got a good nights sleep the day the medication arrived. Thank you Advantix and Chewy. September 13, 2016
Rated 5 out of 5 by It works! None of my dogs have had fleas for years. Advantix has been working for them since we lost our last cat in 2009. We used Frontline until then, which also worked but it was a nuisance to open, and I was always afraid that I would scratch the animal when applying it. Advantix has a real applicator, is easy to open and easy to apply. It doesn't scratch. We have had 3 dogs on the Advantix and no problems. And it works! September 5, 2016

Rated 5 out of 5 by Always effective I've tried to go to the less expensive stuff -- doesn't work as well. September 7, 2016
