Rated 5 out of 5 by Kills all fleas on my dogs within twelve hours..ALL OF THEM! I have 2 dogs, one outdoor and one indoor along with 2 indoor cats and I would have a problem with the outside dog bringing in fleas when he sleeps overnight! I would also notice that mosquitoes would fly all around my outside dog. K9 Advantix II stops this!! It repels fleas, ticks, mosquitoes and most pests so I do not have to worry about him bringing fleas inside. This not only kills, it repels so they do not jump on my dog and "hitch a ride inside"! LOVE IT!! September 12, 2013

Rated 5 out of 5 by This does everything it claims to do. I switched from Frontline to K9 Advantix II after my dog's groomer recommended it. I am so glad I did. It is much more effective. September 6, 2013

Rated 5 out of 5 by works for me I use this product from Spring to Fall on my medium hair mixed breed 50 pound dog. Although we live in the middle of the woods, she has shown no evidence of any fleas or ticks this year or any other year I have used this product. I did not put it on early enough one year and found fleas. After applying, they were gone within a day or two. Previously used on my Greyhound although fleas did not like his fur as much. August 21, 2013
Rated 1 out of 5 by No effect Didn't work at all on either one of my dogs. They have just as many fleas as before. Even vacuumed the carpet and put flea spray on carpet. Advantix is a dud!! August 20, 2013
Rated 1 out of 5 by It used to work. I have been using this product for a few years and always was happy with how well it worked. The past couple months it is not working. I have been finding ticks on my dog. Very disappointed. I just do not understand why it is not working anymore. August 19, 2013
Rated 1 out of 5 by 3 dogs and it didn't work on any I purchased 1 xl, 1 large and 1 medium and it didn't work on any. I have to spend more money now to get rid of the fleas. August 18, 2013
Rated 5 out of 5 by you have to try to see if you like the products that has great features for your dog it works great. you don't have to worry about any fleas getting on you. August 17, 2013
Rated 1 out of 5 by Product didn't work! We are still picking ticks off of our dogs. I feel that buying this product was a waste of money :( August 17, 2013
Rated 2 out of 5 by Not as effective as in the past. I was disappointed in its delayed effectiveness this year. We still had fleas 3 weeks after application. I have used it for many years on many dogs. I have heard rumors that fleas are developing resistance. August 14, 2013
Rated 5 out of 5 by Good overall product for flea protection. I have 2 dogs and neither one has any side affects from the use of this product. The only fleas I see are dead ones! August 14, 2013

Rated 5 out of 5 by It Works! No fleas, no ticks, no pests.............It Works! August 13, 2013
Rated 5 out of 5 by Great and easy ordering process Ordered this on line and it was very intuitive and a great price. Will buy again August 12, 2013
Rated 5 out of 5 by Works for "me" K-9 Advantix is the only product I have tried that actually does the job on my Golden Retriever. I tried several others with poor results and have kept old Mac "bug free" from about age 3 to his current age 11. The generic even worked fine for several years until I could no longer find it! August 12, 2013
Rated 4 out of 5 Usually Super This year my dog had a tick on his midsection. Several years ago he has a tick on his ear which was not surprising. No fleas ever so I can't complain too much. August 11, 2013
Rated 5 out of 5 by Works where other brands did not.. In using this product on our 4 year old female ShiPoo, this product continues to work even exceeding one month if we are a week or so late in applying. Another well known brand only worked for about a week, after which fleas abound, and scratching commenced on the poor dog, even without intermediate baths. K9 Advantix II seems to work very well, is long lasting and most important non irritating to our ShiPoo. The product is easy to apply. Petcarex pricing is very reasonable, and we love the 6 month pack and automatic prompt renewal. August 10, 2013
Rated 5 out of 5 by Works well for my dogs. My vet recommended this product because the fleas have not become immune to this medicine yet like some of the other ones on the market at this time. August 8, 2013
Rated 5 out of 5 by Effective in stopping the fleas! Had always used Frontline, no fleas but the occasional tick. Switched last year after the first time my little Pom mix had fleas in 13 years. K9 Adv. has more features to stop/block/kill the fleas and it worked pretty quickly. Always am hesitant to use this on a small old dog but she's had no side effects. August 7, 2013
Rated 5 out of 5 by Once flea & tick product I'll use This is the most effective flea & tck pruduct I've ever used on my dogs. I've used others, but the K9 Advatix II has prove to be the best for my dogs. I also like that it deters biting flies and mosquitoes too. August 7, 2013
Rated 2 out of 5 by only effective for 2 weeks I have used this product in years past with great results. This time my dogs had a flea problem only 2 weeks after applying the liquid. Someone has suggested that buying from an online dealer has the potential for purchasing expired products. I don't know that I believe that but am wondering why the fleas are back after only half of the time of protection has passed. August 6, 2013
Rated 4 out of 5 by So easy to use I have had my 2 Brittany's on this for 2 years and never had any problems with fleas my dogs love it. August 6, 2013
Rated 1 out of 5 by The worst I put advantix 2 on my Shepherds 2 weeks ago. The next day, I saw some fleas moving slowly and dying. However, it has not gotten rid of all of them. This product does NOT repel. In fact, I think it made the fleas reproduce. They have more fleas now than ever. They are inside dogs.My house is ceramic tile and I vacuum area rugs regularly. I have treated my yard,They have a 2 week old puppy, which also has fleas now. This product is the worst!! August 4, 2013
