  • The only one I trust
    Have used Advantage II on all my animals for decades..One season I tried a different flea tx with added protection & my one dog got extremely ill..We almost lost her!! I switched back after she recovered & none of my animals have ever had a negative reaction to Advantage II & I have never had an issue with fleas..I shouldn't have messed with something that was working..Lesson learned by on 04/06/2020
  • Dogs do well in the winter.
    This product protects from giving fleas a warm place in the winter and ticks a place to jump to. by on 11/28/2019
  • awesome product
    We deal with fleas on our side of the mountains and ticks on the other, since using Advantage for 12 plus years we have NEVER had a flea or a tick! by on 10/21/2019
  • Always satisfied
    I must have protection from Ticks because we live in a forest and there are deer. I rely on Advantage II and have not been disappointed. by on 09/10/2018
  • Advantix II Keeps the terrible Tennessee Fleas Ticks GONE
    Tick and Flea's in the state of Tennessee are terrible Only stuff found to really work Plus I do admit I do dust under bedding etc with Diatomacious Earth I am horribly allergic to flea bites so do everything possible. Prefer Natural but none work as well. by on 08/06/2018
  • My Pal Meds
    I feel my Pal Hilo is in good hands with your medication that we purchase for him. Thank Advantage II by on 07/27/2018
  • Excellent
    I have been apart of the Pet Plus plan for several years. It is one of the best bargens you can have for your pets pest control. by on 07/08/2018
  • Waste of Money
    My puppy is 12 weeks old. We bought the K9 Advantix + thinking it was the best on the market for topical apps. It does not work. She scratches worse now than before we treated her! We find full grown adult fleas on her every day. Our yard and home has been treated and I wash her bedding daily and treat it as well. The fleas must be immune to this stuff because they are still on her. I'm going for the chewable Nexguard. Don't waste your money on these topicals. by on 06/26/2018
  • Only Flea Treatment That Works
    My dog is severely allergic to flea bites. When she was diagnosed with the flea allergy our vet said that our area was number one in the US for fleas on dogs Even if one bites her she breaks out in hives and gets a bad rash that leads to an infection due to the constant scratching. This is the only flea treatment that actually works for her. It really does kill the fleas before they bite her. We wouldn't use any other flea treatment on the market. by on 02/27/2018
  • Great product for the money. No Fleas, No Ticks
    compared to other flea and tick products, this one is the best value for your money. by on 07/12/2016

  • excellent product
    this is very good flea medicine, been using it for years. Petrx has the best prices too. by on 12/05/2015
  • Please send me return instructions
    I have emailed you to explain that prior to receiving my order from you I realized, after buying some Advantage 11 at Petco, that it doesn't work on Rokko. He has a severe flea allergy and ended up in the doggy ER. The vet there put him on Bravecto. So I cannot use the Advantage I ordered from you. I haven't opened it. It isn't a prescription med so I'd like to,return it.Thanks. by on 10/06/2015
  • Advantage
    We received our Advantage for dogs promptly after ordering. The price was very reasonable. We'll be ordering from you again. Thanks! by on 09/04/2015
  • easy to use
    I have used this product on my dog for several years with good results. Last two times it does not keep the fleas off of her. Did they change the formula? There seems to be less in the tube. what would you suggest by on 08/31/2015
  • Best liquid flea control
    Having tried everything from all natural remedies to other chemical brands, Advantage II works the best for us. We have a multi dog and cat household and flea control is important for their comfort and health as well as ours. This product, unlike others we have used, works for the full 30 days as promised. I recommend Advantage II especially for multi pet homes. by on 07/30/2015
  • Advantage II for Dogs
    When I found the website, it appeared as if I was going to get a substantial discount on the product. As it turned out, I did not understand or see the fine print that it was necessary to join an associate of the seller. When I factor that in, it cost more than if I had purchased from an alternate retailer. I feel that Website did not make it clear. While I would recommend the product, before you buy from PetCareRx, read and understand the fine print. by on 07/20/2015
  • Been using it for years
    We are happy with Advantage II, and have been using it for several years on our two dogs. We apply it after their baths, every three weeks, and they rarely have any fleas (once in a while, during hotter months, one or two pop up, but die).We have found the product to be pretty effective, and we prefer topical treatments like this, to anything they'd have to ingest. by on 05/24/2015
  • Great stuff
    I had bought another brand and it did not work at all! My vet recommended Advantage, and I can see why. My dog stopped suffering from fleas quickly. by on 04/12/2015
  • Didn't have staying power
    Seemed to work great for the first two weeks then fleas started appearing. It is now week three, and while they are not covered in fleas, they will be in another week. by on 02/27/2015
  • I'm not a vet
    Advantage II was recommended by the vet. The product works well for my dog. I could only tell people to check with their vet before ordering this product. by on 01/22/2015
  • great product
    I have tried this product before and it works great by on 01/21/2015
  • non greasy and waterproof.easy to apply
    I have3 dogs and when 1 gets fleas, the other 2 will also be bothered by them. This product has eliminated any festation problems and my dogs don't scratch very often. by on 12/24/2014
  • This product work the best of any I've used.
    After trying alternative products to save money, I found they didn't work nearly as well and had extra steps in the instructions. I also bought the feline version for my cat as well. by on 10/29/2014
  • Advantage II works great.
    However use of the web site is a chore. There has got to be a better way to order without going through all the unnecessary steps required. I give the web site an unsatisfactory rating. by on 10/07/2014
  • It's been working consistantly for 7 years.
    Happy with this product, have not seen one flea or tick in 7 years with our dog, it's easy to use and effective in flea and tick prevention. by on 09/06/2014
  • Product is as advertised.
    Product is as advertised. Service is great and correct. by on 08/27/2014
  • A great product
    Advantage II for Dogs is priceless at our house. Our dogs are always running in and out of the house and never have had a flea on them. by on 08/26/2014
  • This product works good
    I have been using this product on my dog for over a year. I like it much better than Frontline. I have not seen any sign of fleas. The weather is very hot and dry were I live and fleas can be very active. So far I have not had any issues with this product. by on 07/28/2014
  • No fleas!
    I have four indoor cats and a dog--flea control is an important element of being a pet person. My dog gets a monthly dose of Advantage, and as a result is not a host for these pests. The cats get treated with feline appropriate meds as well. This all works so much better than the days when I remember using fleas powder, fogging flea bombs, etc., and still had the critters jumping around the floor and making everyone miserable. One dose a month is all it takes! by on 07/26/2014
  • Petcare Rx is a real find
    I usually get my pet care meds from another website. However, pet care RX was having a sale on the advantage II was at a real bargain. They have excellent customer service, and I certainly will do business with them again in the future for this product.Advantage two works well for my pets, however this season is very active for fleas and ticks, so I had to reapply after only three weeks. by on 07/22/2014
  • I love this product, so effective!!
    I use the drops on my dogs every month. It works perfect, no fleas, eggs, etc. Great product for the price. by on 07/22/2014
  • Less effective then in the past
    It does not seem to work as well as it used to when I first started using it on my pets years ago. I still use it for my cat and 1 year old because Confortis upsets my puppy's stomach. My older dog is fine with the pill form which actually works better but requires prescription. by on 06/25/2014
  • This stronger form of flea spray has been recommended for my cats
    The vet has told us to use this stronger flea spray by drops for kitties enjoying outside time on screened in lanai. by on 06/20/2014
  • great price and works!!
    i've had various dogs over the past 45 years and tried every flea protection out there. some have been okay; the cheap ones are always losers (as are the ones they sell in the pet stores). I've finally found a winner! Advantage II stops the scratching almost immediately and lasts between doses. by on 06/16/2014
  • Does not work on Florida fleas
    I thought that Advantage II would be more effective than the old formula. Not at all. I have three dogs and ordered a 12 month supply, what a waste of money. by on 04/26/2014
  • This product works great on dogs or cats
    I have 8 dogs of my own and I rescue dogs and cats, So I have found this product if I buy the Large size for the dogs it the same ingredients as in the cats Advantage II, So I pour it in to a empty bottle and give the cats about 1/2 cc with a syringe Empty of course and clean, then yorkies get about 1/2 cc to 3/4 cc have small and larger ones, and larger dogs get about 1.5 cc to 2 cc.. It really stretches out the budget and I never Have a flea problem , this product works very well in Mo. by on 03/30/2014
  • So far, so good!
    Had been using another product and it has lost its effectiveness. Begun using Advantage II after it was recommended by a friend. by on 03/18/2014
  • Advantage II Flea and Tick Med for Dogs
    Avantage II is the only flea and tick med for dogs that has worked for us so far. The price is right and the med was delivered in the expected delivery time! by on 03/11/2014
  • Flea and heartworm meds work great
    Excelent company to deal with over the phone or internet. They are fast and friendly in the service they provide. I would highly recomend them. Bob J by on 02/27/2014
  • Easy to use dispenser
    I have used this product on my dog for 7 years and never had a problem with fleas or ticks. by on 02/15/2014
  • Product works
    Have used this since a puppy and has always worked well by on 02/09/2014
  • Advavtage 11 versus Frontline Plus
    Usually use the Frontline but find that it's effectiveness deminishes after constant use. We switch to Advantage or Advantix every so often because they contain a different chemical and the fleas can't adjust to it as easy as the repeat Frontline Plus. by on 12/26/2013
  • Product Flaw.
    Normally this product works but the last batch did not. Had to re-apply after just 2 weeks and it is still not getting rid of the fleas. by on 12/06/2013
  • Advantage II works better on my dog than Frontline.
    My dog stops the scratching and biting faster with the Advantage II. My vet only carries Frontline which is fine if I forgot to order more and need it in a hurry as they do sell it 1 dose at a time. Will continue to order from PetCareRx. Delivery is usually in less than a week. by on 11/29/2013
  • This product really works.
    I tried Frontline and it did not work. I ordered Advantage and now my dog does not have ant fleas. by on 11/26/2013
  • Did not work on my poodle
    very unhappy with product. I bought a 4 month supply and one of the tubes had no product in it. by on 11/23/2013
  • Disappointed
    I only recommend this product because it seemed to work better than the last treatment I tried, however it was only effective for just under 2 weeks. Needing to treat again so soon is not only an inconvenience, but gets expensive! Maybe the product should have lower prices since it doesnt last as long as it says it should. by on 11/20/2013
  • Sorry, haven't used it yet although I have many years ago and it worked well.
    Hopefully it won't make my dog sick like Advantix. Haven't tried it yet. I had to use up the rest of the Frontline I had which was an okay product but I read it doesn't repel fleas and takes time to work. by on 11/13/2013
  • This is only product I use on my pets!
    I have used Advantage since it came out and I wouldn't switch for another product. It is very effective and my cats and dogs have not had a problem with this medication. by on 11/13/2013
  • Advantage 2 for Dogs
    Easy to apply,but not sure if it is working,I have noticed my animals itching and pretty sure I saw a Flea on 1 of my cats by on 11/08/2013
  • Better than Frontline
    Works much better than frontline for flea prevention. Maybe doesn't last as long (seem to have fleas sometimes again after about 20 days or so), but still better than frontline & other products I've tried. by on 11/08/2013
  • It works!
    Both my dogs are flee free for several years. Easy application. I put the reminder sticker (comes in the box) on my calender every month. by on 10/30/2013
  • This product came with 4 month verse 6 month supply
    advertisement was a little deceptive ----normally sold at 6 month supply verses 4 month by on 10/21/2013
  • Multiple dogs and loving Advantage II
    I have 4 pitbulls, I use Advantage each month, I live in the South and have never had a flea problem. by on 10/21/2013
  • This product is awesome.
    This product is awesome. I also purchase the Advantage 2 for cats. I did not have one flea in my home or on any of my animals all season. Will keep on ordering on a regular basis. shipment comes within 3 days of ordering! Great Job!! by on 10/17/2013
  • Wonderful Product
    I have 4 dogs, I missed 2wks of flea treatment, and they all got fleas. I applied Avantage II to all, and within 24 hours all the fleas were gone!!!! by on 09/10/2013
  • not happy
    I can't see that this product has provided any benefit to my dog. by on 08/30/2013
  • Advantage ll for dogs
    This is good stuff! We can't do without it! It keep the fleas off of Daisy and Mousey, our dogs!! It may be a little expensive but we can't do without it! The fleas were really bad this year! Thanks for a really good product! I always go with advantage for the dogs! and also advantage for Max the cat! by on 08/24/2013
  • Great Product
    Easy to use and I have not seen a single flea on my dog since we started using it. by on 08/07/2013
  • No longer works on my dog.
    I have been using this product for many years. In Maryland it worked like a charm, but in Eastern Mass is is not effective at all. I used it last year with fair results. This year it doesn't seem to work on fleas or ticks at all. I am switching to something else and I hope it works. This was a waste of money. I should ask for a refund. by on 07/18/2013
  • Doesn't last as long.
    I was disappointed with the length of effectiveness for this product. I even bought one level higher. He starts scratching and becoming irritated again before I can administer it again. I did not notice this a year ago. Is this formula not the same as the one from the vet? by on 07/18/2013
  • Great
    Fast transaction, fast shipping, great price, great product! by on 07/18/2013
  • not as effective
    I didn't find this product to be as effective as I read it would be. I didn't have a real bad infestation and thought they might need some protection since we've had so much rain. I think I will be looking at another product next time. by on 07/13/2013
  • Good Product, Good Price!
    I prefer this product over others mainly because of its value. A box of 6 applications costs less than the different brand containing 4. A good bargain....a good product! by on 07/08/2013
  • Bad advantage
    The product doesn't work at all. I used it on my dogs, a week passed, the flees are still there. Pls refund my money by on 07/01/2013
  • Works really well!
    My vet had recommended Frontline and I have used It for several years with my other dog. It did not work for this particular pet. I also tried Armour from Wal Mart and it was ineffective. Advantage has worked extremely well and I will definitely continue to use it. by on 06/28/2013
  • Complete protection
    I used this product last year. I was a little Leary because if the good deal I got ordering it. I had 3 outside dogs and 2 indoor cats. The fleas were out of control last year. They attacked us and our ankles. My animals got infested with fleas. It was horrible !! I started using this product and it cleared up all the dogs pretty quick. We did baths and baths and house bombs and bombs. This medicine broke the cycle and my dogs remained flea free !! I have used this ever since. No side effects and no skin problems. 2 boxers and a chow chow. by on 06/22/2013
  • Do not buy
    Did not work at all for fleas. Applied one tub at the 1st of the month and one in the middle. Thedogs were loaded with fleas, as per my groomer. Total waste of money. Trying comfortis now! by on 02/02/2013
  • Advantix II for dogs
    Great product. I like that it not only protects against fleas and ticks, but mosquitos, too. It's so quick and easy to use. Never saw any indication of pests. It costs a little more than other brands, but it's worth it1 by on 09/29/2012
  • When you give up, this is the last product you will ever need.
    I copied this for the cat review also. I was at my wit's end with powder, shampoo's, sprays that did not work and since I winter in Florida and my animals (cat and dog) became infested with super hardy flea's and were getting a reaction to the best flea shampoo I could get. I re-washed my pet with plain natural shampoo, let hair dry, applied Advantage II (cat and dog), by morning I could not find any flea's and keep working for 2 months! It will be the best money spent. I promise! by on 09/25/2012
  • Advantabe II
    I have a new terrier who got flea's just before his monthly treatment and with the treatment he was back to normal without all the scratching and chewing the very next day. I will continue to use the product and order it and other necessary supplies through this site by on 09/02/2012
  • K-9 Advantage II
    I recently puchased the Advantage II for my dog, Abby. I have not seen a flea or tick on her. Thanks for a great product. by on 09/01/2012
  • Adantage 11
    I gave my dogs a bath and applyed this 1 week ago and they stillhave fleas by on 08/16/2012
  • Just stopped working
    I started using Advantage on my 13lb shih tzu in March and applied the last does a little over a week ago. It has been working great until..... Today after we came in from our walk I found at least 10 fleas eek. It's too soon to apply another dose, I think we are goig to switch back to Frontline. by on 08/01/2012
  • Flea war
    I use to give Comfortis to my dogs but it was very expensive especially since I have 10 dogd ( I rescue them). Advantage II works fairly well but is not as efficient as Comfortis. You always get what you pay for I guess. by on 07/25/2012
  • Advantage II for Dogs
    Living in South Florida, hot, humid, and copious amounts of rain, Advantage II works extremenly well (waterproof) on Samantha, a ten year old rescue lab/boxer and spends most of her time out doors. To date there have been no side effects to her. Initially, she was started on Advantage and has remained flea, tick and larve free. I would recommend Advantage II. by on 07/24/2012
  • This Product does not work on ticks
    This product is listed under the flea and tick product line; therefore thought it would be good for our dogs to protect them against fleas and ticks. They had so many ticks on them and several of them were attached. Now they have Lyme disease! I would not recommend Advantage II for dogs to anyone! by on 05/07/2012
  • Only flea medication I could find that worked
    Much like many other posters, my English Bulldog had picked up a bad case of fleas from a kennel and we had a big problem on our hands. I spent nearly a month trying cheaper products but nothing got rid of them entirely. Finally, I went ahead and spent the money on Advantage II and I'd say within 2 weeks, we were flea free. Another thing that impressed me was that this product cause zero skin irritation for my bulldog which is another issue I have with him many times. In summary, this may be a little more expensive than what you're used to paying, but it works! by on 01/11/2012
  • Advantage is the best!
    I have used Advantage on my 12 year old terrier mix male dog for about that long. He is very senstive to flea medication. I would put a flea collar on him and he would throw up within the 1/2 hour. Flea shampoo..the same thing. My vet recommended Advantage nearly a decade ago and I used it ever since. Highly recommended. No side effects on my dog other than a little itchy at the application site. by on 01/04/2012
  • Good and Bad
    I've been using this product on our chihuahua for 4+ years. I agree that it does what it says it does and we have never seen a flea on our "Paco" since using Advantage II. My issue with the product is that I know that it burns him because immediately after application he rolls on his back and keeps rubbing and squirming for several minutes. I hate having to apply this monthly knowing that even though it is helping him, it is also very uncomfortable for him at time of application. by on 12/28/2011
  • Advantage 2 WORKS!
    We found fleas on our dog in the beginning of October. I immediately went online to look for the best stuff to get rid of them as I had slacked on our other spot-on treatments and now no one wanted to even pet the dog because of the bugs. :( Advantage 2 had great reviews - I immediately went to ALL of the stores and everyone was out. Instead of coming right home and ordering it from here, I decided to try other products. $300+ later and I still had fleas. Fed up, I ordered Advantage 2 on a Sunday night, it arrived on Wednesday and the fleas were GONE by Thursday night! The insert says that you may see a flea or two for the next few weeks, and I am not going to lie, I have seen one or two here and there, but I had combed over 30 out of his coat the night before I applied this. I will NEVER NEVER not use Advantage 2 and have recommended it to all of my friends who are experiencing a flea problem right now as it seems to be an epidemic. BUY IT! PS - the dog is being loved on all of the time now and he is allowed back up on the beds! THANK YOU ADVANTAGE 2!!! by on 11/02/2011
  • advantage 11 for dogs
    I use this as directed and it does not work on ticks by on 08/31/2011
  • Does NOT work
    I bought this for my dachshund. This product is $60 waste. He is infested with fleas, I've applied it twice. The first time I applied it I bathed him and them applied it. Two weeks laster he's already reinfested with fleas! I live in a rural area, its hard to keep the dogs away from grass. I've used frontline in the past with no issues. by on 08/19/2011
  • It works
    I use it on my 70 lbs. dogs and the fleas die and my dogs are happy dogs. by on 07/14/2011
  • Advantage is the best!!
    I've stopped using your product after two months and used a less cheaper one to save money. Big mistake it worked for two weeks but after that the fleas came back. I'm sticking with Advantage it really works!! by on 06/20/2011
  • Good product
    Works on fleas, just wish it worked on mosquitos, and lice as well. Maybe they can improve on a good thing. by on 05/20/2011
  • Debbie-Owner of 2 toy poodles.
    I live in a mobile home park. Lots of dogs and cats. My neighbor and I keep our dogs dosed with this product. We have no fleas or ticks on our dogs. This is the best! My neighbor goes to the dog parks and all around. No problems. We have a lot of wild cats in this area and they bring fleas. Still no problem. Our dogs are pest free. Thank you for a wonderful product. When used per directions, all is well. by on 05/14/2011
  • Wonderful Stuff!
    I actually bought mine on ebay to be able to use for my cat and dog, for $15 I have a 3 month supply. After 1 day on my 9 week old puppy (who was kept in a dirt lot and INFESTED with fleas when we adopted her!) the only fleas I found on her were DEAD fleas! I used a sentry product on my cat, to no avail. He was badly infested and in quarantine, but am waiting to give him a bath before I try it on him! I was on this site looking at reviews! by on 05/03/2011
  • Bad smell!
    After I applied the product, my dog's skin had a strange reaction after a few hours. His odor and breath became unbearable even after bathing him. His area in the house also picked up the odor, which I can't seem to get rid of either. I am going to try bathing him in tomato juice since it works for skunk sprays which act similair to flea applicators. If it doesn't work, then I'll have to suffer until the med wears off....3-4 weeks! by on 04/29/2011
  • This is the Best
    This is the only thing that works. I think any bad reviews, the people writing them must be getting paid by the competitors. My daughters dog was infested with fleas and came to my house and brought them here. We gave the dogs a bath and immediately put Advantage on them and it worked and they have never had a flea ever since. we even put it on them every 6 weeks. They go for daily walks and they never have fleas. Totally recommend. Do not buy anything else by on 02/27/2011
  • Did not work
    I used this product on my 4 dogs and it did nothing. I've used other spot on flea and tick products that have worked wonderfully for my dogs. I thought this would be the same and I could save a few dollars since it's cheaper but I was dead wrong. Instead I wasted my money and had to buy the better brands to get relief for my dogs. by on 01/20/2011
  • Some dogs may be sensitive
    I was using Frontline and a couple of months during the summer I could not find any to purchase. So I decided to purchase Advantage and I used it for three months. Every month after giving my Westie this treatment, she got diarrhea and the last month was obviously feeling worse because she laid around for nearly three days. Obviously there is no way to tell your dog is going to be sensitive to any medication but don't ignore the signs. by on 01/13/2011
