  • great product
    We moved to NC from TX and had never dealt with fleas. The fleas here are really bad. We tried all of the top spot treatments and nothing worked until we found this one. Even at the vet they have s chart that says the others are not effective. Don't waste money starting with the cheap stuff cause they probably won't work anyway. by on 04/07/2014

    We've been using Advantix II ever since we got our dog. The vet suggested it at the time he was getting his vaccinations. Buddy has been flea and tick free since we've been using it and it doesn't seem to mind its application. by on 03/27/2014

  • easy to use - works great
    Advantrix works better than other products I have tried including higher priced merchandise. It is easy to use and I will continue to use this product for my pets. by on 03/26/2014
  • This product was a perfect fit for my pup!
    I had always used Frontline for my dog Michael, he is 4 years old. He began having skin irritation due to flea bites, the K9 Advantix2 repels the bugs, no more problem!!!!! by on 03/20/2014
  • Good product
    Used for at least 20 years on all of our dogs. Seems to also help repel the fleas. by on 03/18/2014

    Most effective med for prevention andKilling fleas and eggs,Frontline is preventativeI changed to Advantix and will neverusr Frontline again. by on 03/01/2014
  • K9 Advantix II for dogs
    Have used this product for several years. Works very well and pets have no reaction. Switched from Front Line, however, I hear they have changed the formula and may give them another try in the future. by on 02/27/2014
  • Is the best one I found for my dogs
    I used to use another brand but at the time I had two dogs (Yorkies) and they became allergic to it the hair on their backs started to change color and getting very thin. Our vet said it was an allergic reaction to the product and to try Advantix II, never had another problem again. I highly recommend it. by on 02/24/2014
  • Love this product!
    I decided to use this product on my pets after my mom used it on her flea-covered dogs. She had tried other products before, but this one worked the best at completely eliminating all the fleas from the dogs. After witnessing that, I have used only this product on my 15-pound Westie/Jack Russell mix, and have never seen a single flea on her, or in my house. And she is one of the healthiest animals I've ever seen. I'll never use anything else. by on 02/14/2014
  • Better than Frontline
    When I was using Frontline, my dog continued to scratch quite often. Now that I'm using Advantix he almost never scratches. by on 02/14/2014
  • Love the over effect of the product but will comment in review section.
    K9 Advantix II for dogs is a Great product. I Love the ease of use and all. I do however find that I have to buy the next size up because it does not last the month as it says it will.I find that by using half(or so) of the larger container,it works better. Otherwise in about the end of the second week my Paisley starts to scratch.South Florida has lots of Fleas and ticks and I do not want my Dog to ever suffer!Thank you by on 01/24/2014
  • Excellent flea and tick prevenative
    Very economical flea and tick preventative. Can even be used on puppies. by on 01/19/2014
  • Advantix 11 is a great product that WORKS!!!!
    We had a terrible flee season this past year and I thought I would never get them under control in or out of the house and on both our cats and dog. I had tried Sargents (don't!!!#, Frontline Plus #helped a little), but Advantix 11, both dog and cat really did the job. Highly recommend this product. Will never use anything else. by on 01/17/2014
  • Easy to use gentle on your pet
    Best results of products we have tried. Less sting to the skin and pleasant odor. by on 12/28/2013
  • Item Great but Service Lacking
    Product has protected my dog for over 6 years. Great product but don't make any returns and expect a quick credit. Make sure you place a tracking # on any returns. by on 12/22/2013
  • Great product
    I have 2 dogs that receive this medication. Neither have had any adverse reactions, and it seems to work perfectly for both of them...rarely see them scratching themselves too much... by on 12/12/2013
  • This product has been very effective in treating fleas.
    I have used Frontline Plus for 10 years on my dog, however, a couple of months ago my dog had a severe case of fleas and itching, Frontline Plus wasn't effective in getting rid of them, I changed to Canine Advantix II and the fleas and itching are gone. by on 12/11/2013
  • works well
    We've tried other tick and flea products and this works the best by on 11/30/2013
  • K9 Advantix II
  • Application not easy for long haired dogs
    My lhasa apso has thick hair and it is difficult to apply the product to the skin level because it is difficult to reach the skin after parting the hair. At every application most of the product is applied on the inner portion of my dog's hair. by on 11/28/2013
  • great product
    love product! used to use frontline plus, but started finding fleas on my dogs...switched at the recommendation of our vet and it works great! by on 11/25/2013
  • Tried the rest, this one's the best.
    Living in the mountains of the NW with 2 long hair dogs is a challenge to say the least. I used to judge when to put my Flea/Tick meds on when I saw the first tick after the last application. They never lasted as long or controlled the complete cycle as described. When my Vet said "get ADVANTIX!" I was not expecting any difference, but I was truly amazed. I just don't have to worry about ticks/fleas anymore. I have gone over the suggested re-application dates many times and have not had any ticks or fleas in years now!!I by on 11/22/2013
  • K9 Advantix for dogs
    We changed to this brand because it not only kills fleas and ticks but also repels them, which saves us the hassle of pulling them off of our dog. I am glad we switched to this brand, it seems so far to do what it says. by on 11/21/2013
  • This is the best tick preventive I've used
    I used to use frontline,it was useless ,I literally would take 100's of ticks off my dogs each year,totally ineffective ,since switching to k9 advantix II ,if memory serves me correctly I think I took maybe toe ticks off at the very beginning of treatment ,that's it,GREAT product and these guys had the best delivered price ,I highly recommend it. by on 11/17/2013
  • I love this product
    My dog has dry skin. Advantix works well for him.I tried Frontline once, He was very uncomfortable - scratching and chewing at himself. I thought he had developed a skin problem.Than I realized he was having a bad reaction to the product. I have never had a problem with Advantix and feel secure in using it. It keeps him flea and tick and mosquito free. It does not make him itchy.After talking to neighbors, I realized that I was not the only one having problems with Frontline. I suggested they switch to Advantix, and once they did, their dogs stopped scratching and chewing at themselves also.Thank you for carrying Advantix. by on 11/13/2013
  • Works for my 3 dogs
    I have three dogs and I love this product. My dogs have never had flea's. I do find ticks on them but we live in a heavily wooded area and the dogs are outside most of the time. by on 11/11/2013
  • This is a very good product.
    This is a very good product. I have a pomeranian who was getting ticks. Ever since using this monthly, there hasn't been a tick or flea. Also, works great on my black lab. The only down to this product is the price. I feel it is very costly, but I haven't gone to a cheaper product because this works so well and does not have a harmful effect on my dogs. by on 11/10/2013
  • Effective product
    I live in a rural area with deer all around us. In the four or five years I have used Advantix products, my dog has NEVER had a tick attach to her. I am very impressed. by on 11/10/2013
  • Could be easier to get out of package.
    We had neighbours who let their dogs run free. Flee infested to the point of losing their hair. Tried Frontline, didn't work. Advantage a miracle. Cured everything. by on 11/09/2013
  • 3 dogs, no fleas
    I have been using this for a long time and it has been an excellent product. I especially like that it helps to repel mosquitoes in addition to fleas and tics. I have even been in a bind and gone a bit longer than 30 days without getting overrun by fleas. I love this product. The price is higher than most other preventions, but I have had such good luck I'm afraid to try anything else. by on 11/01/2013
  • Product seems to work effectively
    A good product but after being on the market for as long as it has surprised the cost has not gone down. by on 10/25/2013
  • Good product
    I feel this is a good product for our region and pet's needs. It is one of the few to ward off mesquitos too. by on 10/21/2013
  • Works very well in our climate
    Was worried at first about one dose completely covering our 110 lb Great Dane puppy. It is tough in our Florida climate with all kinds of parasites. So far, there have been no issues with any break through fleas and the mosquitoes have also been at bay. Product is very easy to use, doesn't smell awful, and seems to be a good value for the money compared to the cost of getting rid of fleas. by on 10/19/2013
  • This is great.
    This product works better than any brand I've tried. Easy to use, not messy, and effective. by on 10/13/2013
  • Shipped fast and always at a great value
    I love how i can get on this website and get my dogs medication for less than at the retail stores. It makes life easier for me and my dog. With K9 Advantix II, I know that I am getting a quality product for a great price. It does everything it needs to and I didn't find a single flea or tick on my dog all summer long. It's nice not to have to worry. by on 10/13/2013
  • great product
    best working for my dog. I will never use anything else. The cost is a little high. by on 10/11/2013
  • best product out there
    because of cost i tried other products,and just wasted my money and gave no relieve for my dogs. and came back to what i know works. by on 10/09/2013
  • this is normally a good product
    I have used this before and was very happy with it. the product I recieved from you did not kill the fleas and I believe that you are selling out of date product and will not be purchesing any more from you. by on 10/08/2013
  • The best choice
    We tried several other over the counter brands and they were totally ineffective here. I never had flea problems before, but here in Southeastern NC, they are awful. This is the only product that worked! by on 10/07/2013
  • Worked well this year
    I've used this on two GSDs and haven't found any fleas in the house, no ticks on the dogs though, I seldom take the dogs to areas I know are tick infested. In 2011, I did take one GSD to where I later learned from experience has ticks and did find one on her. Removed it and have used this product since then. Again, no fleas or ticks in the house so far up to this month and year. I have four cats in the house, also, but do not use any product on them and still, no fleas / ticks in the house. by on 10/05/2013
  • Great Price and product!
    I have been using K-9 Advantix II for a long time and it works great. by on 10/04/2013
  • This product works great!!
    K9 Advantix II for Dogs is excellent. I live in Florida where fleas, etc., are rampant. In the years I've been using this for my toy poodle he has NEVER had fleas!!! by on 10/04/2013
  • Worth the extra cost!
    I have a black lab who absolutely loves the water. We live on a lake, so she is in the water every chance she gets. With K9 Advantix 2, she remains protected from fleas and ticks regardless how often she goes swimming! With other flea and tick medications, I had to retreat because the medicine would wash off of her with her frequent swimming and then I would find ticks on her. If you have a swimmer or bathe your dog frequently, get the peace of mind that comes with using K9 Advantix 2. by on 10/03/2013
  • Skin reaction
    As far as the effectiveness of the product, it seems to be working. No more bugs. However, I have noticed that he keeps trying to scratch between his shoulder blades. I will keep a watch on this. Perhaps I need to give him an oatmeal bath and a moisturizing rinse to help his skin. Any suggestions? by on 10/02/2013
  • Best product
    Have used other similar products. Best of them for our dogs. Worth trying; you won't buy any other. by on 09/29/2013
  • This is the first time since I have been using this product that it has not worked.
    I have been very disappointed with it this year. I've used it for the last 3 years and it has always work; not this year. Had to change. Very disappointed. by on 09/27/2013
  • product has always worked
    Dr. recommended and I buy through this site as it gives the best value for the product. by on 09/27/2013
  • Easy and quick application
    Effective flea and tick repellent. We have 2 dogs, in the 40 lb. weight range, that frequently demonstrate adverse reaction to many brands of this monthly type of application. Their reaction is vomiting which routinely occurs for 1 or 2 days after the application; however, K9 Advantix II appears to upset them a little less than other brands tried. by on 09/23/2013
  • seems to be doing a good job
    I wish that the drops would come in a stronger dose. I have a 120lb dog so we need to use the meds every 3 weeks by on 09/22/2013
  • A great product!
    I have used this treatment for years on my 2 rescued Jack Russell dogs. It is the only medication that also repels/kills mosquitoes too. Our summer has been cooler & wetter, so we have had many more mosquitoes than usual. I feel relieved every month when I put on this topical treatment. It's very easy to apply and my dogs line up quickly for their turn. PetCareRx has never failed me when I order from them. The cost of this treatment was good too. by on 09/14/2013
  • No fleas or ticks so far
    I've been using this on my collie for 3 years now. No problem yet with fleas or ticks. No problems with it bothering the two cats in the house, either. by on 09/14/2013
  • Have used all of the top brands on the market. Advantix is by far the best and is one of the only brands that also includes mosquito protection.
    Effective against fleas, ticks AND mosquitos! Consistent quality and performance. by on 09/13/2013
  • Our dogs have never looked so good!
    We have 4 large dogs and they have never looked or felt so good! 2 of them are over 10 years old and they have never seemed so happy and stressfree. A few days after applying the K-9 Advantix II, their coats were shiny and soft. No flies or mosquitos buzzing around. We will definately re-order next week. by on 09/12/2013
  • 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!! by on 09/12/2013
  • K-9 Effective
    This product is easy to use and packaged so that it stores safely. My dogs don't seem to mind the scent and they don't try lick it off each other. We haven't had a pest on their skin since starting this product. I do check our pets after walks, but they have been tick free. Hooray! by on 09/08/2013
  • 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. by on 09/06/2013
  • pricy but effective
    Wait till you have a deep discout before buying. The mark up on theses chemicals is ridiculous by on 09/01/2013

  • 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! by on 08/12/2013

  • 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. by on 08/10/2013
  • 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. by on 08/08/2013
  • 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. by on 08/07/2013
  • 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. by on 08/07/2013

  • 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. by on 08/06/2013
  • 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!! by on 08/04/2013

  • this product does not work for fleas . a waste of money .

    have tried many flea & Tick preventatives with NO luck until K9 Advantix II which WORKS VERY WELL - Thank you for a product that finally does the job! by on 07/26/2013
  • This is the BEST flea medication you can get
    This product has been a real lifesaver helping us to control a flea problem we had a few years back. We were using a similiar product for many years and it just lost its effectiveness. I will never go back and try anything else. This is the only flea medicine my dog will ever use. by on 07/23/2013
  • Great quality and price!
    Flea and tick medication is very expensive, but with PetCareRx, it's affordable! I love K9 Advantix II because I don't have to worry about my dogs getting any kind of bugs! by on 07/23/2013
  • it works
    I do not like to put anything on my dogs but to combat fleas this is a must. I am a pet groomer and have seen dogs come in infested with fleas. It is very sad for the dog so I would rather use the flea control. this product has always worked for me and PetCareRx has always given me the best prices. by on 07/22/2013
  • Only brand that works for ticks in the summer here in NC
    For here in North Carolina I have found that Advantics II is the best thing to use on my Westie,especially in the summer. Trust it .... by on 07/22/2013
  • worked great no more fleas
    I used this for the first time and it killed all the fleas, I used it with sentinel and my three dogs had really bad fleas for a month and now they're gone within a week by on 07/21/2013

    The product is the best I have used. It keeps my dogs free from bugs of all kinds. I use this particularly one because it repels mosquitoes. by on 07/19/2013

    Could always be less $. Must work well no flees or ticks! by on 07/18/2013
  • Never found a tick
    I've used frontline for years with all my labs. Switched to this product because I hear that ticks are becoming resistant to flea and tick preventatives. So far, so good. A bit pricey, but it has proven effective on my black lab. by on 07/18/2013
