Rated 5 out of 5 by K9 Rocks K9 Advantix II is a great product. Haven't seen a tick on my dog since I started using. I hadn't really stopped to think about what "Repellency" really meant when I was initially searching for a tick procuct. But, when you stop and think about it, how cool is that ticks don't actually have to attach to a dog if they are repelled before they get a chance?!? Hard to argue against that when you're thinking about the well being of your family friend! November 6, 2012
Rated 5 out of 5 by No problems at all. Works great for us. I have not seen a flea on our Toy Poodle. Ever! What is most impressive is that we are in an area with a huge mosquito issue and I have watched mosquitos hover around him and NOT land on him! That makes me very happy. I have never seen a tick either, but we don't have a tick problem in the area... Mosquito problem mainly n October 27, 2012
Rated 5 out of 5 k9 advantage II I have been usung K-9 on my dog Abby for the last year and it really works on keeping fleas, ticks and biting bugs off of her. It's a good product and does what its suppose to do. October 22, 2012
Rated 1 out of 5 by Didn't work This is my first time using the product and three weeks later i still saw fleas on my dog. He was straching a lit I am so angry that I wasted my money. Never buy again October 6, 2012
Rated 5 out of 5 Very Good Product I have been buying K9Advantix II for several years now, and it seems to keep fleas and ticks off my dog and my sister's two dogs very well. Also, I use this product and not other stronger products because I don't want it to be too toxic for my dog's skin. I will be purchasing this product for as long as I have dogs. October 4, 2012
Rated 3 out of 5 K9 Advantix II I have been purchasing K9 Advantix II for my Dog Newton, as well as my sister's two dogs, for several years now, and I trust it to kill fleas and ticks and hopefully not be poisonous to my dog's system, as can some other brands can be. I think PetCare RX is a good company to purchase from; they ship your items right away. I received mine in about 3-4 days. October 3, 2012
Rated 1 out of 5 by Don't work I don't know why but this product did not work on my dogs. I put it them twice now an they still have fleas September 29, 2012
Rated 5 out of 5 Product used K9 Avantix II I am very pleased with pricing and delivery time. The K9 Advantix II is great for my dogs. It works very well. I put it on them and seems like instantly they stop with the flea signals. Thank You PetRX September 28, 2012
Rated 1 out of 5 by Not working within 1 week of application Have used this product for 1 1/2 yrs and over the past 2 months it has stopped working, dog is loaded with fleas and I am totally frustrated about paying for something that is ineffective. September 22, 2012
Rated 5 out of 5 A Great Product Advantix is great product. No ticks or fleas on my dog since I have been using it September 20, 2012
Rated 3 out of 5 Owner/Operator As a rescue sanctuary located in a heavily wooded area, we have to deal with wildlife bringing fleas and ticks into our area. We feel that the K9 Advantix II is the most effective to keep pests down for a full month. Not sure if it really repels mosquitos, however. We take extreme care to chage and scrub all water containers and kiddie pools (for the dogs) every other day to prevent mosquito larvae. Only drawback is cost, but we have to do the best we can to protect the animals. September 18, 2012
Rated 5 out of 5 Works Fast! I've used K9 Advantix II for several years but never really knew how well it really worked until I brought home a new dog that I adopted from the city pound. Did not know she had fleas until we brought her home. She had been spayed that day so we couldn't bath her. We put a K9 Advantix II on her and within 5 minutes, we started seeing dead fleas falling off her. Within 1/2 an hour, they were all dead. September 14, 2012
Rated 1 out of 5 by It is supposed to do a lot , but it doesn't. Treated 4 dogs with this $l50.00 for 3 - 4packs and within 2 weeks the dogs have fleas again. There should be a money back feature. September 10, 2012
Rated 1 out of 5 by Ticks get fatter on this product Our 57 lb Irish Setter remains covered with ticks despite the use of this hideouslyy expensive product. We spend an hour or more every evening removing ticks from the dog. It was a total waste of money. September 10, 2012
Rated 1 out of 5 by No good THis worked for me in the past but is not working now. Have to keep treating house and using flea comb on my dog. Product is useless. September 7, 2012
Rated 5 out of 5 Best Protection Ever.... I have been using K9 Advantix for six years on my Yorkie Kerious. It truly is the best product ever for him & my family... It protects him from fleas, ticks, mosquitos, biting flies, etc. Even when we go on vacation from state to state.. We love it & so do Kerious! Now, he can really enjoy life as a doggy with truly no worries! September 3, 2012
Rated 4 out of 5 This is a good product I have been using this product for quite some time on my little one's and it works great! Pet Care RX always seems to have a good deal on it too. My only draw back is when you pay $18 for 2nd day delivery and Fridays, Saturdays, Sundays and any holidays, those days don't count. So you are only going to actually get 2nd day delivery if you purchase on a Mon, Tues, Wed or Thursday and you had better make sure it is super super early if you live on the West Coast.

Rated 1 out of 5 by DOES NOT WORK USED THIS PRODUCT ALL THE TIME FOR MY DOGS THIS TIME I GAVE MY DOGS A BATH AND PUT IT ON FOR THE 2X IN A MONTH AND THEY ARE STILL BITING AND SCRATCHING!!! I HAVE 2 SMALL DOGS THAT ARE INSIDE AS WE LIVE IN AN APARTMENT COMPLEX AND ARE WALKED. THIS DOES NOT WORK August 25, 2012
Rated 3 out of 5 Care Giver The best thing I baught for my dogs with then a hour the fleas was gone August 19, 2012
Rated 5 out of 5 Trusted Flea & Tick Medication I have been purchasing this product for my large Yellow Labrador, and for my sister's two dogs for quite some time. I feel it is a good product to use against ticks and fleas getting onto your pet, without being too toxic on the skin of the animal. I would hope it is not hurting the animal. We have to trust the products that we buy to protect our beloved pets. August 18, 2012
Rated 1 out of 5 by USELESS!!!! Such a waste of money!!!! Does NOT work at all!!!! Paid arm and leg for useless product, never will buy again!! Do NOT even think about buying this product! I hate to just throw it out, but i wouldn't want to have my dog eaten by fleas with the product, so TRASH it goes!! August 18, 2012
Rated 1 out of 5 by It's not doing the job! My dog is still full of fleas, he's still being bitten, and now my cat and my house have them too. I'm pretty upset at wasting my money and putting my dog through the routine for nothing. August 17, 2012
Rated 2 out of 5 What happened?? I have always loved Beyer products. I work for a chain pet store that sells these products as well as a few other brands. I have LOVED this product and have pointed COUNTLESS people towards it, and have recommended it to so many people. But now? I took a good look at my dog and saw what I thought were tiny white heads. Pimples is what I thought they were. I scraped one off to see if it was a pimple and there was no pus. I look at the white thing and it had LEGS. My dog is covered in tiny white ticks. I believe these are young ticks. I don't know what to do. It seems that Advantix's claim to repel and kill ticks only applies to adult ticks. The young ones can transmit diseases too. She has no fleas, no adult ticks, I was so pleased. Now? I am furious. I am a minimum wage worker, can barely afford this stuff, and its not working. My dog is miserable. August 16, 2012
Rated 1 out of 5 by It did not work for ticks I used advantix II on my dog about 10 days ago. She never got wet, no bath, no rain. Today I took her to the groomer and they found a tick on her. Fortunately it was only a brown tick. Will never buy this again. August 11, 2012
Rated 3 out of 5 K9 Advantix II K9 Advantix II has been used on my 2 cockers Spaniels for 5 months, doing an excellent job of keeping the fleas, mosquitos under control. No more skin allergys on 1 dog. I highly reccomend K9 advantix II. Wish my vet had reccommended 4 years ago, when the one dog began to have skin problems. Thanks to K9, she is free of the bumps and loss of hair. August 11, 2012
Rated 2 out of 5 Its ok It does work like it's supposed to but it is messy, the instructions state you have to distribute the medicine in 4-6 spots along the back so its everywhere. I would gladly pay the extra $10 for Frontline Plus which you are able to use on just one spot on your dog's back. August 9, 2012
Rated 5 out of 5 Best topical flea & tick prevention product. Period. I've been using K9 Advantix II for over 4 years, and have never had a single problem with blood-sucking pests on my animals or in my home. We live right on the border of the woods, and go hiking quite frequently in the woods, and my dogs never bring anything home with them. Even with the high numbers of ticks this year because of the warm spring, we don't have a problem thanks to this product. I'll pay a little more for the quality product I get with K9 Advantix. August 2, 2012
Rated 2 out of 5 by We still have ticks Even after applying this product to my 22lb dog...I am pulling ticks off of him at least 2 times a week! I was hoping this would prevent that. He is mostly indoors, but we take him for walks in areas that obviously have ticks. I don't know what else to use. I am very disappointed that a brand that claims to prevent ticks is not working for us. I haven't seen fleas though, so I guess part of it is working. August 1, 2012
Rated 5 out of 5 K9 Advantix II is GREAT!!! I have used K9 Advantix II on Onyx since he was 6 months old. He is now 3 years old and has never had a flea problem or any bad reaction to the medication. You won't be disappointed if you give this product a try. August 1, 2012
Rated 1 out of 5 Awful product, doesn't work at all Terrible product. I applied a week ago, and the fleas were gone for a few days but are now back and worse than ever. Tried a second dose, and the fleas are practically swimming around in it and enjoying themselves. Do not order! I'm going back to frontline immediately! July 31, 2012
