Frontline Reviews

Sunday March 8th 2020 I administered Feline Frontline to my Cat who was 15 pounds and 10 years old. Monday March 9th 2020 I came home from work and found him lying in my bedroom floor having seizures. My husband and I wrapped him in a towel and started our way to the emergency vet. Before we made it to the end of our road we live on my beloved passed away. We adopted him when he was two years old. He was only an indoor cat and had just had a healthy checkup at the vet. I cannot honestly say that Front-Line caused his death but it is ironic. Kitty Heaven is he.

Carey - 8 years old - mixed breed - 35 lbs. We applied Frontline Gold for the first time ever to our dog on 01/16/20. Within 5 hours she would randomly scream out in pain/because she was scared and jump into our arms. At the time we thought maybe she hurt her leg or back and would touch her spine, rotate her legs, etc. without finding any indication of soreness anywhere on her body. This would happen sporadically on Friday and Saturday. By Saturday evening, it was happening more frequently. And at this point we realized that our dog was having mild seizures. She was not losing consciousness, but she would cry out/get this look about her and then burrow into us and her whole little body would tense up, she would lick her lips (salivating), and stretch out her neck and put her head high into the air.

Frontline Gold was purchased & administered to my cat 12/11 @ vet clinic. Brought in healthy, came home & sneezed for several days, scratched & licked obsessively causing loss of hair, peeling pads and lumps appearing on various parts of body. Cat has lost appetite for food & water and has lost weight. She is in pain, disassociating any human contact, constantly sleeping in secluded, dark places in home. Fearing her death, took back to vet for help. Paid $330 for bloodwork (CBC) to check for liver &/or kidney maladies; ruled out all fatal cat diseases; rec’d skin scrape 2, ** 80 mg/ml injection; provided ** .3 for pain maintenance.

My cat is an older indoor feline and only goes out occasionally on the front porch. I have been treating him with Frontline Gold and called the vet because it does not seem to be working. He said I can give to him 2 times a month instead of once and that seems to be working a bit better. I do think the fleas build a resistance to these meds, only wish they were a bit cheaper since they seem to take so long to start working.

Their money back guarantee is a joke!!! I purchased a 6 dose Frontline Plus for my dogs. After 10 days there was no change or relief. Treated them with another dose. It got worse. I went back and purchased ** and saw a noticeable change within 48 hours. I called to express my concerns. I was told in order for the money back guarantee I had to treat for 3 months. My dog was bleeding in spots from the chewing/scratching. I was NOT subjecting her to that for 3 months when it was clear that after one month your treatment was not working. I was just told by one of your representatives (reading from a script) that how your product works is that it kills adult fleas and keeps females from laying more eggs.

I have treated my 4 cats over 4 months & continue to find fleas. We have followed protocols for flea treatment of our home as recommended by our vet. Seresto collars seem better, but they cause scratching & hair loss at neck. I will admit the collars seem to be more effective, but our vet now is recommending **. I think the fleas are just becoming resistant. These are indoor cats, no less. We are very frustrated & concerned for our fur babies' welfare.

Started using Frontline Plus 2 years ago. At one stage I was using it every two weeks. It just doesn't work, my 3 cats are infested and so is my house. When I complained to the the company they sent me a questionnaire to fill out - I filled it out and they replied rather flippantly- saying they are picking them up from outside. Before that I was using Advantage but was buying it from the chemist but at £27 for 3 pipettes it was too expensive - but it worked. My cats are 15, 15 and 16 years old and I don't really want to keep stressing them out with fortnightly defleaing, hoovering several times a day and bathing in cat shampoo which they all hate) so I'm now trying Advantage again and getting it a lot cheaper online - hope this works.

I contacted them to tell them I’ve got fleas for months now and been using product for years. They only try to tell me how to bomb and clean my house. I told them I’m diligent with my Dyson vac and clean every day! They told me to keep using the frontline. It will work. After two ear hematomas and an abscess to my little dog leg I found out he’s suffering from a flea allergy and of course it’s costed me!! Finally the doctor's office told me that Frontline Plus hasn’t worked for a couple years now and they prescribed NexGard which I found is from this same lying company. But I used it because I was desperate and within a week he’s better and stopped shaking his head and scratching. Still to doctor's office told me to use nexgard only as needed (Not monthly) because it isn’t good for your pet.

I purchased Frontline for my cat, from a Walmart store in Hamilton, NJ. My cat was a very loving cat, very playful, wake me up every morning, and just a part of my family. I applied Frontline on my cat on Thursday night, 10/3/19. On early Monday morning 10/7/19, all of a sudden, my cat's body began to start jumping, flipping, and he started to shake and seizure. His chest began to jump, and his heart began to race extremely fast, and then he died on us. After being in complete shock, an emotional wreck, and angry, I decided to contact Frontline and let them know what their product killed my cat. The person that I spoke to, asked me a few questions, gave me a reference number, and told me that someone will contact me asap.

Bought Frontline plus. It didnt work so I called frontline to complain and the lady on the phone was so rude. Didnt even offer to give me a refund or anything. Dont trust this company. They say 100% guaranteed. That's false.

My dog got fleas 7-8 years ago & his savior was Frontline. Since then I've religiously used frontline on him thru at least spring & summer & no problem! Works excellent! Last year I adopted a cat. Since he often goes outside I resorted to frontline. This kitty runs everywhere, unlike my dog. He brought back fleas. I was so shocked. I'd treated him with frontline plus 2 weeks prior to noticing fleas. After seeing fleas on both I bathed them in flea shampoo, cleared the house & treated them with frontline. Every week I wash their beds, bath them & spray & vacuum. 2 months later I'm done with frontline. Switched to advantage & now I can stop spending money on cleanup finally.

I have always used Frontline on my dogs and it's done very well, until this year. I feel like I'm wasting my money and my dogs are paying the price. Poor little guys are miserable. I see no decrease in the fleas and I'm trying to find other ways to treat them. I am not getting what I'm paying for! What a disappointment. I will be switching to something else in the future.

I am going to keep this simple September - 2017 I took my German Shepard to the vet for a routine Blood! He had skin issues. September - 2017 - The blood work came back. Went through it all. Everything all was fine. I Used Frontline. MY DOG HAD SEIZURES and DIED! I never thought of this because this was the only thing different was flea and tick (vet prescribed).

I found ticks on my dog and used Frontline Plus on my dog. It has been over a week, and I pulled two more (attached) ticks off of him last night. This product did not work at all. It was expensive and a complete waste.

I called the company at 1-800-660-1842 because after 13 years of using Frontline Plus monthly on my 2 older dogs, my dogs have fleas. (I also used this same product on my other dogs for years prior.) Their customer service representative explained to me the life cycle of the flea and how the medicine works multiple times (which I was told that I obviously didn't understand) and the change in weather conditions, as if I'm ignorant and the weather hasn't changed at all in 13 years.

Frontline just doesnt work. I didn't even see a decrease in the amount of fleas in both my cat or dog. I'm on a very tight budget so to spend $135 on the medicine for it to not work is heartbreaking because I cannot buy another brand until I have saved up the money again. They won't refund. I just can't believe that companies like this can just get away with selling products that don't work, it is disgusting.

I used Frontline Combo for my dog for over 10 years and I didn't have any problems with fleas or ticks until recently. On the last lot I purchased, less than a week after application I found fleas on my dog. I noticed also that the package design is different and I wonder if maybe this is now produced in China or they changed the formula. This would explain why it's not efficient anymore.

Adopted a new kitten a year ago, when I took him to the vet to be neutered we discovered he had fleas. I have three other house cats which have never had or been exposed to fleas. Have been treating the kitten and one of my adult cats that the fleas have jumped on since last March with Frontline only to find it is absolutely worthless but quite pricey. The vet sold it to me. I was shocked with the price and find it to be nothing more than a total waste of money. Save yourself the aggravation and money and try a reputable product.

I would not recommend this product to anyone. My poor baby Bella is at the vet 8/24/19. They are keeping her overnight. The medication poisoned her and she is staying at the vet for a couple of days. I pray to God that she makes it. I will never buy this product again and I hope somebody else doesn't. The pain that she is in from the poison in her is horrible. I wouldn't want anyone else's baby to go through this. Thanks for the worse experience Frontline. Melinda Norfolk NY

After reading reviews of other pet owners and their dissatisfaction with Frontline I now realize that has been my problem all summer long. I have 2 cats. I have been giving them Frontline monthly for years and never had a flea problem. Now I have a serious flea problem and realize the Frontline hasn't been working. The past two applications almost seemed to be empty when I applied it. Very Disgusted!!! And continue to fight the fleas on my pets and in my house.

I bought Frontline for my 4 cats because the vet stopped selling Vectra. Three weeks have passed and my cats are still suffering from fleas. Frontline It's expensive and it's crap. Don't waste your money. Buy Vectra on Amazon.

I have never been so disgusted with anything as I am with Frontline Plus! It's expensive and it does NOT work! After treating the yard and house and my dog, the Frontline Plus still did not work! My dog has been suffering with being bitten by fleas. She can't sleep or eat! I am trying Vectra but it's not much better! It's just a money making scam from these companies who claim that their products work. I ABSOLUTELY DO NOT RECOMMEND Frontline Plus! A real WASTE of your time and money! Do yourself and your pet a favor and stay away from the Frontline Plus!

I have treated all my animals with Frontline. I thought fleas were just extremely bad Last year and this year. I even bought the Seresto collars for the dogs and flea collars for cats. I have treated the yard, treated the house and religiously used Frontline monthly. My poor animals were miserable. I ended at the vet because my one or boy started whining. Turns out Frontline is not working and many people have complained. My dogs attire on Nexguard now and my cats Brevecto. The second day You could tell a difference. My animals are finally getting some rest. It's sad to know they have suffered this long and that I have wasted so much money. I have 3 boxes of unused Frontline here now. I think the company should reimburse for unused portion. Will never buy product again!!

I have been using this product religiously as directed for 2 years on my cat... It does not work! I apply it as directed every 3 months... My poor kitty is full of flea dirt and fleas... It's all over my house! I applied it 2 weeks ago and with a flea comb, I got tons of fleas off of her! And there is no expiration date on it! I am pissed! Will never buy this product again!!!!

I used Frontline plus on my two chipoodles. It did nothing. They still had fleas. I called customer service and explain how the product did not work. She told me it was my cat. I told her my cat was also treated but not with Frontline. She told me that I would have to send her a receipt proving that I had my cat treat it and to treat the dogs three more times with Frontline. I told customer service if it did not work once why would I spend the money three more times. She called me a liar about my cat. Not only is the product bad so is the customer service.

TLDR: This product sucks. Don't waste your money or your time. I put this on my indoor only kitten about 3 days after I adopted her (around July 1st). She was about 12 weeks old at the time. This past weekend on July 28th I noticed she started itching a lot and shaking her head and found what looked like flea dirt. I was skeptical because I knew she was on the medication but I gave her a bath to check. To my horror all the fleas came up to her face. Unsure if she got it at the vet or someone just tracked it in since we've never had a problem with fleas. Looking back at my videos, what looked like harmless scratches or head shakes (which I thought was due to her long ear hairs getting tickled) dated back all the way to July 7th.

My poodle still has fleas after two weeks of applying a whole tube of Frontline Plus and then applying a second application of a few drops. He’s sleeping in a closet at night which he has NEVER done and acting strange since applying this stuff. I see flea dirt and he continues to scratch. He is miserable and so are we, seeing him in such distress... We used this for years with no problems. Are the fleas now immune? I think this should be investigated or has something happened to the formula?? Something is WRONG!

About 3 weeks ago I found a flea on my arm. We treated our 2 indoor cats right away. Our male runs outside sometimes for a minute or two if we don't catch him in time. So we figured he brought them in. We treated the cats two weeks ago with Frontline Plus for Cats. They still have fleas! We'll find a dead (or dying) flea here and there, but there are a ton of active fleas still around. Where my male cat lays, there's still tons of flea dirt coming off him. My female is very scabby.

After applying Frontline Gold to our cat, we noticed her acting very strangely. Whenever we let her inside, she jumped onto the counters or furniture and leaped onto tables, chairs, etc avoiding the floor. Our vet said they had reports of other cats acting like this. It was as though see could see something on the floor and was frightened to walk there. Same with carpet and tile. Has anyone else experienced a reaction like this?

I purchased Frontline Plus from Chewey.com. IT WILL BE FIVE MORE DAYS before the 30 days are up before I can give her the third dose. I put the product on for the past 2 mo. and 3 wks. exactly as directed. My dog STILL has fleas and really rough spots that could be flea nests. She has little bumps in her ears. She scratches all the time and I see fleas on her.

I am contact you today regard a product. Frontline Plus for cat. I purchased this product and it came sealed in the box with lot number and all the information stamped on box and also on the sealed applicators. Says for cat use only. When we took the green applicator out it say for use on 45-88lbs dogs only with picture of cat crossed out. All of them are like that. I can send you pictures if you would like. My concern is if I had not look at the green tube it would of went on a cat that is about 10lbs. The epa numbers do not match the package either inside or outside. Please contact me back regarding this problem.. If this was a packaging error a lot of animal can become very sick or even worse.

I have used Frontline Plus for 1 complete year documenting it on the calendar every time to ensure not missing a dose. I have also spoken with Frontline's reps. many times ensuring me that the product would work in time. My cat is infested with Fleas. I would not waste my money on this product. I bought 12 months worth and they would only refund for 1 month.

I've notice they happened to me that has happened to others ordering off Amazon. I actually applied to to my mama cat and I just happened to see a dog on the green dispenser and I immediately gave her a good bath. I almost put it on my other cats. I am so upset by this. I did get a refund. I just wonder if someone that works for Merrick could have done that on purpose.

Inside the 'Frontline Plus for cats' box that I ordered, there are 3 vials that are marked "Frontline Plus for dogs, 45 - 88 lbs." I am currently trying to contact Merial. Thank goodness I caught this in time.

I am horrified by my experience. I bought a 3 pack of Frontline Plus for cats from Amazon. Box arrived, said it was for cats. Inside the box the outer foil said for cats. The vial/green squeeze thing said it was for dogs 45 to 88 lbs. First - never mix flea meds between cats and dogs. Dog flea meds are toxic to cats. But second, even if it was okay, that would have overdosed my cats. I can't even think about the worst outcome! I called Amazon and was refunded, but I also called Merial. This was clearly an issue at their plant - where the vials were sealed in the wrong foil pack. Very scary. They're going to send me out a replacement and they want me to send them everything so they can investigate further. I emailed photos and am waiting for the label to send the stuff back. BE CAREFUL! I don't want you to lose a kitty! Check your medication before applying it.

I spent over $100 for this for my 2 dogs and they still have fleas. I feel so bad for them because they are itching like crazy and I feel like there's nothing I can do for them. I've spent over $100 on this Frontline stuff and flea collars and now I just guess I'm going to have to take them to the vet and spend more money.

I ordered the Frontline Plus for my cat. The box was for cat and so was the entire packaging, but the actual medication was for a 45-88 lb dog. Luckily I double checked the medication before I gave it or I would have overdosed my 8 lb cat. Now I cannot get ahold of their customer service to warn them. I am very disheartened by this company.

On May 10, 2019 I noticed my dog scratching and gave her a bath. She had fleas so I went to PetSmart and purchased the 6 dose pack of Frontline Plus for Dogs and applied it. I also purchased another product for my smaller dog, which I will also write a review on! I spent $146.39 on products that did NOTHING! On May 18th I had paid my exterminator to come a treat the yard because I still noticed fleas. He informed me that the product does not work, that fleas get immune to it. I was still noticing fleas and scratching, so yesterday I ended up having to pick up flea treatment from my vet, which is again not cheap!!! So pretty much a month and still have fleas! I called PetSmart to see if I could get at least some of my money back and won’t go into detail about the ignorance of some people. I was told that fleas do not become immune to the product and was asked how long I had been using it.

My experience was very similar to Linda's of Live Oak, FL. except one of my cats died! I noticed a flea on the cat that eventually died (probably three weeks after the previous application of Frontline Plus) and decided to bathe her. There must have been hundreds of fleas on this poor animal. I checked another cat, bathed him, and sure enough, hundreds of fleas came off him, too. He is recovering. I would give this product zero stars if allowed because it is NOT doing what the company claims it should do, thus deceiving pet owners, leading to severe illness and even deaths! Why is this being allowed?

I apply Frontline Gold to my dog and cat and within 2 weeks the fleas have returned. Frontline Gold for cats is less effective than Frontline Gold for dogs but neither product keeps fleas away for an entire month. I have tried applying it after a bath and up to 5 days before a bath but it's the same result. This month is worse than last month. After applying Frontline Gold 2 weeks ago and bathing my kitty 1 week ago, he had live fleas crawling on him yesterday. He never leaves the home and he only has contact with my dog. Since it's not safe to apply another product yet, he had another bath last night. I had this same experience with Frontline in 2013. That time, I had to use Revolution then Comfortis to kill the fleas after using Frontline. I will be switching to a different product as soon as I find one that is safe and effective.

I used Frontline Plus on my pregnant shelties. I had 3 litters with deformed puppies. The first litter had 2 bloated babies. The second litter had a puppy born with its brain outside its head. She also had another that was a bloated baby. The 3rd litter had 3 totally deformed puppies with big cleft palates and deformed jaws. Each of the pregnant girls lived at different houses so it isn't environmental. This is the first time I used Frontline on pregnant girls. Frontline claims it is safe for pregnant dogs. That is not what was true for my shelties. I did notify Frontline but they weren't helpful.

IT DOESN'T WORK ANYMORE. I've been using Frontline Gold for cats on the 1st of every month, for almost 2 years on my two indoor/outdoor cats. Two weeks ago, l noticed one was dropping weight, eating poorly, and seemed lethargic. Took her to the vet and her blood work showed very low liver function and very anemic. When they shaved her belly for ultrasound, she was INFESTED WITH FLEAS... That is what was causing the anemia, and in turn, causing her liver issues. Vet told me Frontline is garbage and switched her to Bravecto. 48 hours, several B12 boosters, some fancy pricey vet prescribed cat food, and $1400 later, she's eating again. She was about 2 days away from needing a transfusion and/or death. DO NOT WASTE YOUR MONEY.

When we first got our dog this product did work for a while. Then it became ineffective. Started using Trifexis for years then that got too expensive so we tried Frontline Plus again. After 3 weeks our dog still has fleas. I called their customer service for their “moneyback guarantee” and they tried to explain to me how their product works. ”DUH.” Told her I wanted my money back and she said I needed to give the dog three treatments before I would be eligible. I hung up on her and threw the two remaining treatments in the trash! This product is completely useless. Don’t waste your time and money. I’m going to purchase the Seresto collar. That seemed to work the last time we tried it.

I put Frontline Plus on my 2 cats 3 days ago. They are losing hair. Spots are scabbed up. My cats are healthy indoor/outdoor kitties. They have never had a problem like this before. I took them to the vet and was told the reaction was from the Frontline was the cause. They did not have fleas before I put the product on. They have never had a flea problem. I use a different product from my vet. I was just trying to save money. Shame on me. It cost me double because I used Frontline! NEVER AGAIN!!

We've used Frontline Plus for YEARS on all of our kitties, but now it DOESN'T WORK AT ALL???!!! Bought it on sale 2 years in a row, as it's so expensive, now have 21 useless doses of this product, not to mention our babies' discomfort from fleas. If there's a class action suit, I'M IN!!!

Last night I asked a question about a promo gift card that was added to my receipt. All the Frontline staff seemed nice and agreed it wasn’t showing up on my receipt correctly. Then a manager type came and was very rude and clearly annoyed. I had been there for over 10 minutes at this point and frankly didn’t care anymore. It wasn’t worth my time. The manager was condescending. I won’t be shopping there anymore.

For me to write a review is usually due to an experience, service or product being extraordinarily great or completely horrible. Frontline Plus for Cats... complete disappointment. My five cats had their first dose of this so called flea “preventative” a little over a month ago. I didn’t see a bit of improvement but thought maybe the next dose will be effective. So a week & a half ago was their second dose. Not only has there still not been any improvement, the fleas are significantly WORSE. This stuff is crap. That’s all.

I used Frontline Plus for 10 years on my Shih Tzu and he never had a flea or tick. He constantly had allergies from the time he ws 4 and we just attributed that to his poor breeding! Now I'm starting to wonder if it was from years of Frontline. I have a 4 year old female who had been using Frontline Plus for all her life and got ticks and fleas 2 months ago! Bought thru Chewy.com so I have all receipts and don't jump thru normal Merial hoops. Ok'ed my refund for a bad batch of Frontline Plus and 2 months later still waiting! Don't need the money, but if I did, Frontline (Merial) guarantee would be worthless.

Just used Frontline on my 2 dogs a month ago and it didn't work at all! It was expensive and since I didn't want to put any more chemicals on my dogs within that month, I've needed to continually bathe them and purchase flea shampoos just until I can try a different product. I will NEVER buy this product again!

I used this product on my Cairn Terrier per product recommendations. He was getting ready to turn 4 and started having ALL of the symptoms listed including violent seizures. He was in ICU at a university vet hospital but there wasn't anything they could do to save him. Autopsy revealed encephalitis but I think that the product played an important role in his demise. My daughter also used the product on her poodle and within 24 hours of using the product he had N/V, muscle pain, generalized weakness, itching, hair loss, uncoordinated movements, excessive salivation, and lethargy. After we realized the cause, we bathed him in Dawn dish soap several times. He is better but still has symptoms. We realized that there was a pattern to his deteriorating condition after the use. My sister acknowledged that she too has had similar experiences after using this product on her dogs. Since this, we have ceased using this product on all of our dogs.

Frontline plus for Dogs does not work to treat fleas. I have always used this products for my outdoor dogs, it certainly helps with ticks but when this season we had fleas. I applied this product to my German Shepard two weeks ago and she is extremely miserable. She is infested with fleas, don’t waste your money buying this product. It is an ultimate loss for your money and your fur baby! So upset with Frontline!!!

I used Frontline many years ago on outside strays and it seemed to work well. At the end of June I noticed fleas on my inside cats and that the outside cat had fleas also even though he’d been on Frontline Plus for months/year. I started all house pets on Frontline Plus and began a strict regiment of sprays with growth inhibitors and DE, as I don’t want to bomb the house because of lung cancer issues. By the end of October, one of the House cats was so sick I took her to the vets. Well, nearly $1,000.00 later, I’m treating her for anemia from fleas.

This has no effect on the fleas for our two cats. Been using regularly every four weeks. We're going to go back to the vets and get their own treatment that although expensive, works. We won't be using Frontline again.

NEVER buy this product. Fleas worse on dog and fleas throughout house and humans. I assumed Frontline was a good product; however, it is the WORST. How can you sell a product with such deception? Our whole house is miserable because of Frontline. We demand some kind of restitution for selling a pricey fraud, and your company should be ashamed and embarrassed. I demand my money back and your company come into our flea-ridden house to get rid of these pests. My whole family, and my poor dog are suffering greatly. Shame on you.

I treat my dog and 3 cats regularly. Used this products 3 weeks ago and then started with an infestation of fleas. This product is a lie and a scam. When I called the company they only explained life of a flea and let me know this is my fault because I let my dog outside to go to the bathroom.

My cat is losing its hair again after putting on the Frontline gold. I had an exterminator at my house for fleas. Both cats were boarded and had a flea bath. When they came home 2 days later I put Frontline and again my one cat’s hair began falling out and I found live fleas on them. For the price they charge for this stuff it should work. Both times it did not help with fleas. Disappointed.

Frontline used to work on fleas where I live. I had used the product several years ago and it worked. However, I got a flea infestation about a year ago and tried Frontline for several months along with using an exterminator for both inside and outside my home. I got rid of furniture and tried everything. I have spent thousands of dollars until finally, I sought the advice of a Veterinarian who informed me that Frontline no longer works where I live. They did have a good product at one time, but they really need to do some research to get up with the times. I got a prescription product from the vet. and two months later, after a year long losing battle, I am nearly flea free. I would not recommend this product anymore.

We've used Frontline Plus as a maintenance for our dog. After noticing our dog bite at herself around six months ago, we started applying Frontline Plus every 30 days, religiously. We are on the last application of a 180 day treatment cycle and we have had to get flea treatment at Petsmart's grooming service. The disappointment with the product comes from Frontline's customer service guarantee. They will tell you a thousand different reasons why your dog still has fleas. And. Their guarantee is good if you buy Frontline Plus from an approved veterinarian clinic and hold onto the receipt. In this situation, they will give you a refund and have your home treated by Terminix for fleas. So, if you want this product and Frontline's guarantee, you need to purchase it from an approved veterinarian clinic.

Frontline did nothing for my cat, especially this year. It always worked in the past. My cat has been treated with Frontline every 30 days this summer and I just found out she is infested with fleas!!

I have two huskies and they both broke out in sores after using this product. They barely had fleas so we were using this spray as an extra bit of security. My older husky is in worse shape because not only does his neck and back have sores on them, he also started acting differently which I'm thinking the spray may have made him sick. This was a terrible experience and this product needs to be taken out of stores before any other animals are harmed.

I say ditto to all these reports. It appear this failure is all since the company changed hands in 2016. We used it religiously up to 2016 and it worked great. Our old dog died then and last year we replaced her. We treated our dog every 30 days since June and she picked up fleas in August and we still can't get rid of them. This was never a issue prior to 2016. Appears to be an attempt to make more money with the same amount of raw material by cutting the amount used and keeping the price up or increasing it. We are done with Frontline forever!

We love the product but the packaging is poor. It is hard to open and the last box we got one of the doses had a pinhole in it. You are pretty much out 12 dollars when this happens. We ordered it online so it was impossible to tell.

I will never again use Frontline for my cats. They are scratching worse than they were before. They have crusty clumps/sores on their skin which were nonexistent prior to using Frontline. I will now need to take them to the vet to get Revolution - a product that works great. I was just trying to avoid stressing out my cats with a vet visit. Unfortunately, the vets will not give you Revolution unless they have seen your pet within a year. And, like an idiot, I gave them a second dose of Frontline, which is when the sores appeared. And, my cats are strictly indoor cats. I think I brought fleas in the house after cutting my lawn. So with limited exposure to outdoors, the fleas infestation was minimal and Frontline didn't even work for them!

I purchased Frontline Plus from Walmart. I made sure that I treated my entire home for fleas on the same day I was treating my cat. I have only 1 cat. No other pets. Since treating the house I have stopped seeing fleas and getting flea bites, but my cat is still full of fleas 5 days after the flea treatment. I called the customer service department concerning the satisfaction guarantee on the packaging and of course got the runaround. DO NOT WASTE YOUR MONEY! Spend the extra 10.00 and buy a different brand!

I have been grooming dogs for 18 years, and have always recommended Frontline to my customers and also used it on my own dogs. Never had a flea problem until two years ago when almost all of my customers began to complain their dogs had fleas even though they had been treated. Since then l have seen more and more dogs LOADED with fleas!! Have discussed this issue with many vets, and was told Frontline Plus is no longer effective, and the company is now selling.

Product no longer works. I used it for years with no problems but this year I might as well have put water on my dogs and cats. Company refuses to stand by its product. Refused to give me a refund. I will never buy Frontline again. I hope it was worth it to them to lose a good customer. I have 16 cats and two dogs, that's over $200/mth in flea control. Poor quality product and poor customer service. Not the company for me.

I gave my dog Frontline Plus (5 to 22 lbs) and approx. 10 days later I had her groomed. The groomer said he had a lot of fleas. I live in Florida and talked to my vet about Frontline not working. I may have to also use Sentinel (expensive) with Frontline Plus. I have used Frontline Plus last year this time and it worked fine. I also used it on my other dog before he passed and no problems. I do not know if it has merit but the owner of a kennel told me on July 3, 2018 that Frontline Plus no longer works. She said it use to work on their dogs for 2 months, not any more. I decided to purchase PetArmor cheaper & has same ingredients and purchased Lavender spray & Natural Flea & Tick spray with Peppermint Oil & Eugenol. I now bath her with Flea & tick shampoo. I really liked Frontline Plus, less for me to do. Thanks for your time in this matter. Happy 4th of July 2018!

On Friday 22 June 2018 I put Frontline Plus on my 20 year old much beloved pussycat. On Saturday 23 June he became lethargic, shivered, threw up and began to lose large clots of fur where the Frontline had been place on his back at the base of his neck. One drop had fallen on his head, and that fur also began to come out. We became very concerned and call our vet and made an appointment. On 26 June the vet came, and examined our cat. She gave him a steroid shot, and started him on an antibiotic.

Have used Frontline for several years as my one dog had a bad reaction to Hartz. This year used as directed and my small dog had a flea infestation and hotspot reaction resulting in a $200 vet bill. The vet tells me she has seen several cases and Frontline just doesn’t seem to be working anymore. I was two months into a six month supply. Customer service requires a receipt and then tells you they guarantee the product only if you have been using for 3 months. Never using again. Too expensive and they don’t stand behind their product.

I am writing this review as a few times we have used Frontline on our wee dog and it has not worked as stated. We have had to repeat the process a couple of times not long after the first treatment. This should not have to be done. We have followed instructions closely to no avail. Very disappointed as this product claims it works and does not. Wasted money and agony to our pet.

I bought a three month supply of Frontline for my pet. After two weeks he was scratching again so I bathe him and put on another supply and two weeks later he is still scratching and there still fleas he was infested or anything. They just don’t repel fleas and this product is extremely expensive to not work.

I have been using various flea meds on my Jack Russell mix with no great results. This last attempt was with Frontline Plus for the last two months. The treatment seems to work for about a week, and then by the end of the second week, the dog needs to be treated again. Which is a problem because they say you shouldn't treat them more than once in 30 days. I'm afraid of the oral treatments but I may have to go that route next January.

I wish I could give "0" stars on this product, but, to give review, you have to have at least one star. Used Frontline Gold for cats on all of our cats and did all the requirements to get rid of fleas and their eggs, throughout the house. 2 months later, still seeing fleas on my furbabies and they are driving them nuts! They have scratched to the point they have little to no hair around their necks. I don't know why or what is wrong with the Frontline Gold, but, I am definitely switching to a different brand.

I have 3 cats, two totally indoor cats, one indoor/outdoor cat. My cats have been on Frontline since I got them (One 12 years, one 4 years, one a year) starting about June I noticed the indoor/outdoor cat (Maine Coon) was covered in ticks. Immediately I combed him/dipped him and cleaned him off. He was on Frontline which is suppose to stop flea/ticks but figure maybe it was a really bad summer.

I started using this for my cat when his last flea medicine was too strong and making him sick. At first it seemed ok. But the longer we used the more immune he has gotten to it. He now has tapeworms from fleas because of this product. NOT working. This is the second bout of this we have been through. The flea medicine doesn't work. He gets fleas. He then gets the parasite from grooming and biting fleas. A vicious circle. I get the medicine through the mail 3 months at a time. Well it is a terrible product. Do not buy it. Now I have to make another visit to the Vet which he hates and start all over again. This medicine is going in the trash... Time for something that works. I am very frustrated.

Well I actually heard good things about this product, and then I tried it on my dog and had a nightmare. My Siberian husky now has a huge sore on her neck from where I applied the medicine. Had to go to the vet, shave her, and will attempt to try other meds and hope it works. Oh not to mention even though she's enduring pain from applying it, it didn't take any of the fleas away. She has bites all over her belly. I only bought one box. Will never buy another and will now try to heal my dog's wound.

Purchased a 6-pack of Frontline Plus for cats at Costco. Applied product to my cats on the date purchased. Eight days later my cat had ticks - five which I pulled out, another one was so engorged it fell onto floor (gross). I normally use Revolution but was looking for tick prevention which Revolution doesn't have. Frontline Plus did not prevent ticks or kill ticks on my cat. I called company and was on hold for too long so I returned unused portions to Costco. I love Costco and Revolution but will never purchase Frontline Plus again. Doesn't work!!

Frontline Plus - 6 months of useless product. Did all the peripheral care, insecticide growth regulator spray, diatomaceous earth, natural products (essential oils), vacuuming, washing... etc... All it did was give my dog the **. Still crawling with fleas. Fleas have developed resistance to this product. Be nice if the company admitted it and pulled this product off the market. Do not waste your money. Advantix is the same situation.

I've gone through 6 boxes of Frontline Plus for dogs. I have 2 dogs, a Shih Tzu and a Boxer, so I had to buy 2 different sizes and went through 3 boxes per dog over the past few months. Not 3 doses, 3 BOXES. This stuff doesn't work AT ALL. I have laminate wood flooring throughout my entire house. My dogs are mostly inside dogs and they are INFESTED with fleas. I'd even go as far as to say that the Frontline is actually attracting MORE fleas. How do I go to a trusted company for flea relief. Use the medicine and get zero relief. My dogs did NOT have fleas like this when we 1st started. I can put a treatment on my dog and within a week he's infested still. Your product is crap and I wasted too much money on this to not work at all. Don't waste your time or your money or risk your dog's health. Frontline will not work! They're a scam!

The product (Frontline Plus for Cats) used to be great but since being bought out in Jan '17 the product no longer works at all. You can't contact the company and they don't stand behind their product. Save your money and buy a less expensive treatment that actually works. They just don't care!

I purchased 1-3 pack of Frontline Plus for my small dog, my big dog and my cat with great regret. I keep flea medication on my pets year round but I usually buy Pet Armor and it works great. They were out of Pet Armor so I spent more money and purchased frontline and I have fleas coming out of the ying yang. I called the company and told them I have used a 2 month supply so far and I have fleas which I have not seen in at least 10 years by using Pet Armor. I have no carpet and I have thoroughly cleaned my house and washed all the linens to no relief. The company was very unsympathetic, did not offer me a refund or replacement and said it takes three months before it works. Their excuses are lame and I will check every product I use and make sure it is not made by Merial, Inc. Their products suck along with their lack of concern. I can see their only concern is taking money and giving water in return.

I am going through a major flea infestation right now. Found flea larvae under a chair cushion and see many eggs. I sweep every other day with an Electrolux, treat with Frontline Gold for 4 months, spray a can of black flag for fleas and ticks and two can of knock out all to no avail. My big cat has pulled most of his fur out on his back and underarms. You can't even touch him. My female cat looks fine but is crawling with fleas also. I finally have had enough. Frontline may be giving me my three hundred dollars or so back. Thank you. I am now a using Revolution and 24 to 36 hours later the fleas are dropping off dead. It's gross but I am so happy. It has been four months of hell with these blood sucking creatures. THANK YOU REVOLUTION.

Never had fleas before, but always use preventative. As soon as I applied Frontline on my APBT mix he broke out in hives and rash all over his body, still has problems now from the reaction with hair loss and eczema! Not going to use this product again.

I have 3 in/outdoor cats & 2 small dogs that only go out in our side yard to potty. One of our cats has a severe flea allergy that causes him to break out in painful scabs, so I keep flea meds on them all year. I normally buy Advantage but Petco was out of product for cats, so I decided to try out FL+ on all our cats to see if maybe it would as well as Advantage. I bought a 3mo supply of FL+ for the cats & Advantage 2 for the dogs & applied exactly as directed. It's as though I have not put anything on the cats. My cat with the flea allergy has to go in tomorrow for an injection because this product is crap. It's bad enough FL+ cost much more than Advantage, but now I have to pay for a vet visit & injection. To make matters worse, he can't have another flea treatment for nearly two weeks because he was treated with FL+ on September 16 (It's October 5 today).

I am extremely disappointed with the product quality and lack of consumer care by Frontline. I raised a concern with them since treating both my cat and dog to their Frontline Plus monthly treatment which made both my pets physically sick and the fleas remained on them. The response I received from them was that my house was infested and I should hoover 'more often'. It was an insult. My main concern was the well being of my pets health having suffered physical side effects from administering what should be a simple flea/tick prevention. They were due to investigate this with my Vet but I have since heard no more from them. I will NEVER use their treatment/products again nor would I ever recommend them! I know of several others who have experienced the same suffering with their dogs when applying this treatment so there is clearly an issue that needs investigating and looking into yet I feel this has not been taken seriously by Frontline.

Treated my 3 cats with Frontline Gold and it absolutely did NO GOOD. I checked and found a flea right where I put the Frontline, what did you folks do with your solution??? Fix it 'cause this stuff does not work!!! Now I'm going to get Advantage and use it right away, the fleas eat that stuff up like a big dinner... Pretty disappointed with you right now and you should send me my $55.00 back... I just treated them 9/24/17 and I see on the box tab 2/17 is that the expiration date? If it is then it probably was outdated too. Signed Not a Happy Camper!!!

I purchased Frontline Plus, used for months and my animals were not getting relief. I used products for the house, washed all bedding and still fleas. So my neighbor suggested Advantage 2. I used it and immediately my dogs and cats found relief... my cash funds ran low so I had to use my CareCredit credit card at the vet to purchase. What they sold Frontline Gold and lo and behold back to the same problem - fleas and my animals no relief. My small dog who sleeps in the bed itches all night. It's ridiculous I spend 135.00 on a product that does not deliver on what it claims to do.

Got a new cat in January and immediately started him on Frontline, as I have with my previous cats. I buy it in three-month packs from my local Pet World at $53.00 per pack. I apply the treatment scrupulously on the first day of every month. At the end of July, I noticed a couple of fleas on the cat. After the August application, he was soon covered in fleas. The house is now infested. I had to get a prescription from the vet ($70.00 in visit fees), and I’m looking at hefty fumigation fees for the house. I contacted Frontline and was told that I could not get a refund unless I had purchased the product from a veterinarian. This is not inexpensive stuff! Unfortunately, I tossed the receipt, never having had problems before. Perhaps it’s time for a class action lawsuit against Frontline.

I have used Frontline for years on both my inside Cat and outside Dog. And it worked Flawlessly Great. All that changed when Department stores started selling Frontline. Now if you use Frontline your animals have fleas, and your house has Fleas. I believe now that they are not Veterinarian exclusive. They stopped using or cut back their main ingredient. Either way I don't use Frontline anymore and I don't recommend it.

I have been using Frontline year round for almost 12 years on my two dogs, they have never had 1 flea on them. Now I need to get more and can't find it anywhere here where I live. I treat my dogs every month even thru the winter.

I have religiously used Frontline for my pets for many years. I have not had a problem until this year. I apply it on time every single month. I change to Frontline Gold for the past 3 months. My dog had been itching but I assumed it was dry skin because how on earth could be fleas. I took him in for grooming and they found fleas on him they asked what product I use. When I said Frontline, they said yes there's a problem with Frontline this year given the weather conditions that we've experienced and the amount of fleas that are out there. Said all the pets that have come in that unexpectedly had fleas they noticed a trend that the owners were using Frontline. They suggested that I use a different product. My dog was given a special flea bath and I treated my house. Should also mention that I have a quarterly pest control service for my property which includes treating the yard for fleas, spiders, ants, etc.

A month ago I found 2 fleas on my 12-pound dog. TWO FLEAS. I immediately bought Frontline Plus from my vet and applied it carefully and exactly as directed. Now, 30 days later, dozens of fleas are all over my dog. I was annoyed & thinking it was a bad batch... Until I read the earlier reviews here and now I'm just glad that she's not dead from it. NEVER USE FRONTLINE PLUS!

So, I have been a Frontline fan from the time I was younger with my first dog, worked great! That being said, we automatically used it for our GSD Shadow. We have always followed the instructions to the T, applied it on time and also our vet recommended putting it on her while she was still dirty because the dog's natural oils help spread the topical meds more efficiently. This summer was a different story. It was about a week before her next dose of Frontline Plus, we were on the floor with our children and my little girl says, "Mom! A little bug!" I looked and it was jumping everywhere. I was like wait, hold the phone! Is that a flea!?! In my house?! Shadow isn't due for her meds yet... I was confused. Why on God's green earth would my dog have a flea on her if she is religiously on her meds?! So I checked her, she was covered in fleas! What does that mean? We have an infestation!!! How could we get an infestation if she is treated?

Frontline Plus - Bought 2 boxes for my dogs for flea control. It is not working and both dogs are full of fleas. We bombed the house & the backyard and they still have fleas. I called to complain to Frontline customer service and she said new fleas can jump on anytime and they will not die. Okay why does it say it works for 30 days killing fleas, ticks, eggs, larvae, etc. Wasted almost $100 on stuff that does not work. I will never buy this product again because it does not work.

I have 6 indoor-only cats. There are no other animals in my home. In June I noticed evidence of fleas on a couple of the cats. My vet recommended treating all of the cats with Frontline Gold. I purchased a 3 month supply from my vet on June 15 for a total cost of $330.72. The treatment was applied to all cats on June 15 and July 15. By August 1 I was finding adult fleas on the cats. I scheduled another appointment with my vet. She concluded that the Frontline Gold was not working and that I should purchase another brand of flea treatment from a pet supply store. She also recommended that I discontinue use of the Frontline product and contact Frontline about their satisfaction guarantee.

I purchased this product and expected it to work. When I call asking for refund due to the lack of the product working, they would not refund unless I had purchased from a vet. Since I purchased from Walmart then the satisfaction guarantee did not apply. However if I had used all the product for 3 months I might have qualified for a refund. In the meantime my poor dog suffers with fleas all over his face as well as the rest of his body after using this product. The representative stated that the product helped control the home more than keeping the fleas off the dog. What a scam...

Bought Frontline from Pets at Home for my cat and dog. Within hours after treatment our healthy cat was vomiting. 2 weeks after the first treatment our healthy cat started to become lethargic and wouldn't eat much, even her favourite treats didn't perk her up. As we were going to bed our cat was at the top of the stairs convulsion. Within minutes she was dead. We gave our healthy strong Newfoundland the same treatment at the same time and she became very lethargic, no spring in her step, marked reducement in her appetite within a day. We never thought anything of it as thought that she might have just picked up a bug.

I have been using Frontline for 5 months for my two cats. For the first two months it seemed to work and I could not find any more definite signs of fleas. I interrupted the treatment for only one month and the fleas came back. I restarted it for the next three consecutive months and the flea issue actually progressed instead of diminishing. I got on the phone with Frontline. Because I made all of my purchases at the vet's office, they qualified me for "a customer satisfaction" program. I opted to have an exterminator come to my apartment as the flea situation got out of control (in spite of constant vacuuming and washing sheets and clothes in hot water). Currently, I haven't been able to live inside of my house for a week because the fleas get on me and they bite. I have bathed my cats and I gave them to a friend until my place is taken care of. My feet are covered in bites.

I've purchased Frontline Plus due to issues with my dog and several fleas. Product states that it will kill any fleas on your animal within 24 hrs. I still have fleas and this product has not worked. I contacted Frontline and asked for a refund. They stated that I need to buy more. I spoke to the supervisors boss and her name was Alisha. She actually stated it takes 24 hours to kill any fleas on my animals. I explained that is not the case. I was told I have to contact a vet to verify fleas are still present. Very disappointed with Frontline. Please feel free to contact Frontline and express your concerns also.

Frontline does not work. I used it with satisfaction for years. Starting 18 months ago, I noticed it wasn't working and supplemented with baths and powders. My Maltese are pad trained and rarely go out. Visiting dogs have evidently left fleas and with Frontline not working, I suddenly have a flea infestation on my dogs and bedding. I bathe them with regular shampoo and flea comb them daily but fleas keep coming. Frontline doesn't even kill the adult fleas. It's mostly alcohol -- not the original oily application. Help.

Folks I have read a lot of the reviews on this site about this particular pet treatment for fleas ticks etc. Please understand, my heart breaks for anyone who has had a beloved 4 legged family member that has become sick or has died as a result of this medicine. I wanted to point out a few things since you all seem to say it worked for years but no longer does or seem like it doesn't do anything.

My 11 pound Pom had an allergic reaction to this toxin. I thought he was going to die he was in so much pain, luckily I contacted a knowledgeable vet who told me to wash him immediately with Dawn dish soap. I did this twice and he eventually came back to his old self within two days. I will NEVER EVER use this product again. Although the product is waterproof it is diluted substantially with the use of Dawn as it strips the oil on the skin where the product lies. Dawn Dish Soap (which they use on animals affected by oil spills) really does work! Thanks Dawn!

I went and got Frontline plus. It had worked for my dog last year. 2 months later, my dogs are crawling with fleas! I got the Frontline plus to prevent my indoor cats from getting them. Now I'm dealing with a flea infestation. I've treated my dogs and cats right (yes, I bought some for my cats too). I thought it would be different for my cats since they're never outside. I thought (at first) maybe it wasn't as potent as last year's batch. Now I have to find something that will relieve my cats & dogs' misery.

At the beginning of April, after a physical at our vet, our 9 year old Pug was declared to be in good physical condition. We received Frontline Plus since we were approaching flea and tick season, though she wasn't much of an outdoor dog. It was purchased directly through our vet, dosage appropriate for her weight, and applied according to instructions. With the first application, we didn't notice anything significant.

I ordered Frontline Plus for cats and applied it as directed. My cat was going crazy when I first started applying the meds. I thought it was just that he didn't like that I was putting liquid on him. But the next day I noticed a chemical burn at the site of application. Hair was completely gone and he did not want me anywhere near that area. He hissed and scratched while I was trying to part the hair to take a picture. I gave up and snapped this while he was walking around. The site is covered by fur but it's about the size of a penny. And the flaky stuff...I hope it's not skin but something tells me it is. Do not use this product!

Although I am aware of the toxicity of poisons such as Frontline, I put one application on my 4-yr old golden retriever due to the extremely high rate of all types of ticks in the Southwestern New Hampshire area. In February 2017 I pulled 4 engorged deer ticks off my golden. So, ten days ago I put Frontline on her. BIG mistake and I hope it doesn't cost her her life.

Took my dog to the vet for a knee problem. Found out my dog is infested with fleas and has Lyme disease. Have always used FRONTLINE Plus. Never again. Called the company and they said their product is not a preventive- it just kills fleas and ticks after so many days. Oh, they said they would refund our money with proof of purchase and a receipt. Bought a 3PK, 3 months ago so no receipt. Found out the hard way. Please spread the word amongst animal lovers.

Frontline Plus for Cats. I used this product on my cat and she had a terrible reaction to this product. She broke out in blisters and now have vet bills totaling $200.00. I wouldn't recommend this product to any animal lover. To see your pet blistered with sores is grievous. My vet took pictures of her sores - unbelievable. Frontline should reimburse my vet bills.

Immediately after applying the liquid to my 20lb dog he became very lethargic. He also began crying as he was laying at my feet. I don't know if he was in pain but something was definitely wrong. I held him in my arms for about an hour then left him out and went to bed. He slept under the bed all night. He seems okay this morning. I will not put this on him again. I was very scared.

I just put on a week ago and we went mushroom hunting, and omg my dog had ticks on him for days, I was very displease with the product. I think a refund should be in order because this product is terrible!!!

I bought this Frontline Plus for both of my dogs thinking that it would get rid of their fleas considering it was over 50 dollars. It did nothing except make their fleas 10 times worse!!! This product is garbage and a waste of my money!!! I am extremely irritated that I even used this product in the first place. Do yourself a favor and stay away from this Frontline Plus completely!!!

We purchased the Frontline Plus product through Walmart and tried the product and it really did not work. What I am complaining about is that the actual vials were not even full on the last dose, in fact nothing was in them. We contacted Frontline directly and they asked if any of the product leaked and the response was no. They told me to get a receipt from Walmart then send the package back with the vials that were defective and it would be replaced. Well I contacted Walmart and they said in order to get receipt would take ages to go through sales and best bet was to contact Frontline to see if they honor their product. I gave up because of time consumed and will burn the amount of cash I spent on it. After 3 months expected the product to work so did not think about even keeping the receipt. Out of pocket $40 for a product that was useless. Its not the money it is the principle of it.

I have never been so sad in my life. After applying Advantage II for Cats to my cat, he became weak, lost use of his hind legs and blind in one eye. He suffered a seizure and died. He was a gorgeous 6 y.o. Himalayan. He's gone. This company should be ashamed and remove ALL products containing these harmful ingredients. Disgusted!

Do not use this crap on your pets. There are so many better and natural alternatives to getting rid of fleas. There's vinegar, **, and diatomaceous earth. These things work too. Frontline and all this crap is all hype and marketing. They use it to fool all you idiots out there and make lots of money. It's a toxic and terrible product and it doesn't even get rid of fleas and it's not safe for animals. People out there are mindless idiots and puppets and just listen to anything their vet tells them. Also stupid clueless people put this crap on their pets every month - you're slowly doing bad to your pet. Do NOT use this crap. Do NOT let these stupid companies get away with these terrible products.

I was deciding what product to use at the store, and after reading reviews on both (that Frontline is supposed to protect from fleas and ticks) I decided on Frontline. I wish I would have read this first, as I just applied a second round of Frontline... thinking I may have not applied it correctly the first time. It did absolutely nothing to kill the fleas, and now I'll have to wait to reapply another product. I used a different product on the dog, since I had already had it on hand, and the fleas were literally falling off in a matter of hours.

Frontline Plus and Frontline Gold are no longer effective in controlling fleas or eggs on pets. We used both products per instructions beginning in June. 100's of fleas nevertheless. We switched to ** by Merck, which your vet will prescribe. The medicine comes in chewable form. No more fleas, eggs, no more itching!!! Frontline and Merial need to realize that fleas across the country are now IMMUNE to their products.

I had my vet apply Frontline to my 80 pound male German Shepherd. My dog became lethargic for the first 24 hours. The next day he lost control of his hind legs. I rushed him back to the vet but he had a massive seizure in the car and died before we arrived.

I have all my receipts for this product. I started purchasing this product back in July. It is now December and the product has not worked. I have followed the directions on the box and no results. I am very disappointed that I've wasted so much money on a product that didn't work! I would like to be contacted by this company to see how they can make it right by me.

The WORSE thing on the market that you can buy for your pet. My ten month old Pekingese has been miserable ever since I applied it. I have always used Advantage and I am going to bathe all of this nasty Frontline that is USELESS off him and purchase Advantage again. This company has terrible ratings and here's another. BUYER BEWARE! DO NOT USE FRONTLINE UNDER ANY CIRCUMSTANCES! It is ineffective and your pet will scratch worse than ever!

I bought Frontline Plus at my local Tractor Supply store because I get a discount as my son works there. I purchased the three-month treatment of three applications for both my dogs, a full grown Golden Retriever and puppy brother. I gave them both flea baths to start and treated them after for the third time 2 weeks ago. They kept scratching but I thought it was just dry skin. When I would bathe them, I didn't notice fleas and that's why I thought their skin was just dry. In northeast Ohio it's cold and it dries out your skin.

I have been using Frontline on my cat for 15 years, Shih-Tzu for 8 years, and Rottweiler for 4 years and have never had any problems until now. I have been fighting fleas on every single animal for the past 3 months. I have been going crazy trying to figure out what is going on but now that I have read some reviews on here, I see that I'm not the only one. I feel horrible seeing how uncomfortable they are; all 3 are constantly scratching, biting, and jumping around like crazy. I'm extremely disappointed in this company because something has had to have changed. I don't know whether it's cheaper ingredients or different ingredients but something has changed. I am extremely upset that after 15 years of using a product that worked, I am now having to fight to make our home flea-free. I use to swear by Frontline and suggested it to everyone... well not anymore. SHAME ON YOU Frontline.

I bought Frontline Plus to help my little shih tzu with her flea problem. Two days after applying the recommended dose I thought she was dying. She couldn't get up, she could barely open her eyes, she was shaking uncontrollably and when she was able to open her eyes, they were dull in appearance. I of course got her to the vet immediately and she had a very irregular heartbeat. The vet told me that it's quite possible that she was having a reaction to the Frontline Plus. I'm happy to report that she is doing well and back to her old self but I will NEVER use this product again!

I have a German Shepherd and live with a family who have 2 med dogs of their own. A year ago when I saw no sign of fleas I decided that it wasn't flea and tick season and decided not to apply Frontline to my dog. It was a big mistake. The next month we had fleas everywhere. We spent the next month bombing, spraying, washing bedding, and bathing regularly to rid the infestation. We succeeded.

All of us here love our four legged family members (if we didn't, we wouldn't take the time to review). My heart breaks to see my cat striving for comfort (licking, biting, jumping around like a mad man) as I do everything possible to care for him. Convinced by my husband to switch to Frontline (because it's a "superior" product), I have found much disappointment. We are now in the 5th month of using Frontline with NO relief of pests. Shame on me, I bought a 6 month supply... I have NOT found 1 dead flea on him and keep having to bathe & comb them out. Definitely a waste of money and I will NEVER use this product again. I'll be switching back to your competitor Advantage II.

Purchased this product 4 days ago because my vet had closed early and I couldn't purchase the Vectra I normally use. Treated my dog as instructed. I may as well have not used it at all. Now my dog has to wait and be miserable for 30 more days until his next treatment. Called Frontline and they Frontline isn't supposed to make your dog stop itching, but is supposed to kill the fleas and it may take "2 or 3" cycles before it works!!! To get a "one time refund" you have to provide your receipt (which naturally I have since thrown out) AND proof that any/all other pets in your home have been treated for 3 months - even if they're strictly indoor animals. Don't waste your money on a product that will give your pet NO relief!: (

I used this on 1 of my dogs for a long time, and the other 2 since I got them 4 years ago. I NEVER used to have problems, the fleas would be gone in a matter of hours. And last til the next application, without seeing fleas. For the last 2 years, it has not worked, nor did another product I tried in between. I went back to Frontline, thinking maybe a bad batch or out of date, but I really don't think that is it. Because now... it does not kill them all, nor does it last even 3 weeks. I don't know the problem is, I really don't. But I am not satisfied and I will look for another product.

I bought a 6 pack of Frontline plus and it did NOTHING!!! Somebody needs to SHUT THIS COMPANY DOWN for STEALING our hard earned dollars!!! I paid OVER $106.00 for that 6 pack... Why is this company allowed to steal our money like this??? It's been said, "The fleas are resistant to the medicine this year." I say THEY CHEAPENED THE PRODUCT!!! Do NOT buy this product. IT DOESN'T EVEN KILL A FLEA EGG!!! RUBBISH!!! I WANT MY MONEY BACK!!!

I have 3 cats and they all got fleas after moving to a new home. I have cleaned the house top to bottom including all bedding, soft furnishings etc and treated my cats with Frontline. This product did absolutely NOTHING to kill the fleas. I groomed them daily and was removing healthy fleas by the dozen. This morning my Beautiful boy Domino died and the fleas left him like rats leaving a sinking ship. This product is completely USELESS. I'm devastated.

I have always used Frontline Plus with no problems whatsoever, but this year it has not worked at all. I have treated my dogs with 3 treatments each of Frontline Plus in just over a month's time and they still both have fleas so bad that they have no hair on half their body, and have nothing but red skin filled with bites and sores, and the fleas just keep getting worse. My dogs are house dogs and every year I treat them in September for a few months until we get a good hard frost, and I have never had any problems with fleas. Now, both dogs have flea-related tapeworms that I also have to treat because the Frontline Plus has not worked.

I spent about $35 on the so-called generic, Walmart brand of Frontline Plus (exact same ingredients). Well, boy I disappointed. Stupidly, I went back to the Kroger Pharmacy and spent $59(!!) on the actual Frontline Plus. It claims my pets would be flea-free in about 4 hours. WHAT A RIP. Not only did it have absolutely NO effect on the dogs, they have POOF anywhere from 1 to 50 fleas on them out of the blue! Although I have (literally) gone (still do) go over my two dogs every 1/2 hour to 2 hours to make sure they have no fleas on them, I always find one to 15-20 EVERY SINGLE TIME. I am not sure what I got for my $50+, but the fleas seem to LOVE them even more. I found that the fleas are a result of my daughter having a cat at my house (upstairs, carpeted area) over the summer when she was home from school. I have bombed, sprayed, powdered (everywhere!), and put the FP on both.

Frontline used to work a treat. Finding dead fleas all over the house within a few hours. Now it has no effect at all. Both my cats are still struggling, despite flea shampoo, bombs and regular maintenance. Frontline has done nothing to help and is now a total and complete waste of money.

We bought this product from our vet almost 5 months ago, for our indoor kitten, & indoor/outdoor dog. We bought 6 month supplies for both. This product used to work great, now it doesn't work AT ALL! I am so mad. We paid almost $100 to gain an infestation. We used the product for 3 months before having enough. We treated the yard 2x, bombed the entire house 3x, called the vet, & then called Frontline. Frontline told me that they offer a "once in a lifetime reimbursement, professional flea treatment done by Orkin, or product exchange". Well it seems wrong that I'm to eat the loss of my money, and exchange it for a stranger to come pour chemicals in my house... only to get fleas again, before the time that I paid to be flea-free even ends.

Cosmo is our medium/large furry Goldendoodle (age 8). We have homes in Texas and New Mexico, where there are plenty of fleas, but we have not had problems with fleas (we use Trifexis) until I ran out of my supply recently while in New Mexico. Since I did not have Trifexis and our vet was in another state, I picked up Frontline at a local PetSmart. After I applied Frontline, Cosmo's flea problem persisted. At first I attributed the problem to a bad, or expired, batch of Frontline. I waited two weeks and, since Frontline seemed ineffective, gave Cosmo a tablet of Trifexis, which we had finally picked up in Texas. The flea problem stopped.

I have used this product in the past and found it very effective. However it appears to no longer work - I was very glad to read other reviews confirming this and yet it is still sold by pet stores in UK at a premium price in multiple doses. I have been told I am not entitled to a refund as there have been no studies to confirm it does not work!! Infuriating - hope that BBC 's Watchdog or some other similar media consumer affairs programme pick up on what is clearly a problem for many pet owners that are left out of pocket and pets that are still very uncomfortable hosting fleas.

We had used Advantage for years and our dog Max had never had an issue with fleas. Our vet quit carrying Advantage and switched us to Frontline this year. We started finding fleas on Max in June and the flea infestation began. We bathed Max at least every two weeks and applied the Frontline as directed. We cleaned our carpets, vacuumed frequently, sprayed our carpets with flea killer, combed max twice daily with a flea comb to no avail.

I used two vials of this product on my dog within two months (each one monthly). The second month did not even finish and already my dog was having fleas. Now my house has them. I had a similar problem last year, but thought I would give this product one more chance. This is a the last chance. What a waste of money. I'm also not happy that I used a toxic product that did not even work on the fleas.

I had used and trusted Frontline for over 12 plus years on both my cats and dogs. In 2015 I moved to a new home along with my five dogs. In the spring of 2015 I noticed that they were chewing and scratching going crazy. I immediately went to my vet and bought Frontline applied to all five, all to no avail. What should have taken care of fleas immediately began a year long nightmare. I couldn't understand WHY we were still dealing with fleas. Not only were my dogs infested, but now my home was too. So I went on the war path spraying the yard every 5-6 weeks, vacuuming the carpet and furniture every other day, washing dog bedding every week, bathing each dog every 6 days spending hours washing and pulling fleas off of them. I bought and bombed the house several times all to no avail.

My completely healthy and happy dog is now dead due to Frontline. I applied it Friday and he became lethargic and unable to move. He was the best dog and just went swimming 2 days ago. Company kills.

I have used Frontline for several years and it worked. Now my poor baby dog has allergies and fleas. Very sad to see what has happened to a good product. We'll never used this again. You should be sued for the terrible sores and discomfort your product has caused on my Skittles. Shame on you???

Used Frontline on my dog for the last 4 years, but alas it is now rendered completely hopeless and my DOG and house has fleas. In my opinion it is now pointless to use Frontline. Lots of complaints about the product, and if only I had seen the complaints earlier I would definitely have changed protection. Fleas all over the dog and I have to wait 2 weeks before putting the new flea control on him having administered Frontline only a week ago. It has caused havoc at home. The whole house have to be sprayed with flea spray.

Recently purchased your product due to fleas. We've had a hot dry summer. I was told by pet store this product was good. We'll after spending close to 200 dollars. Because I have 2 cats and 2 different weight dogs. I'd about swear this product draws fleas to the animals. The cats were flea free till I use this product. I had dogs bathed at groomer they came home flea free. Had house bombed. All the animals are infested I even reposed them as told by the vet. Still have them. This product should be pulled from stores and all pet owners reimbursed. It garbage.

I have used Frontline on my pets for years and this year I have had nothing but problems with fleas. I bought advantage-II for my cat because it was on sale and frontline for my dog because they were out of stock. Within 12 hours my cat was flea free and has been for 3 months now and my poor dog still has fleas. Don't waste your money on frontline. Called frontline hotline and not much they will do for you. They got your money and now they are done with you. I'm headed to the store to buy advantage for my dog.

I have bought this product and it doesn't work. I got the 3 pack and used all three and still my dog has fleas after 3 months of using this product. Used to work before doesn't now I don't know why and the product is not cheap... and seems to me I'm not the only one who noticed it's not working? Now in out 45.00 and no results...

August 2016: I'm so upset I bought Frontline Plus about a week ago, and I put it on two of my dogs and I feel so bad for them because they are still itching worse than before I used this garbage!!! DON'T BUY THIS CRAP!!! BTW, I live in Ohio.

The Company isn't the problem. It's the product I bought. Frontline is a flea & egg controlling & killing medicine for pets. It's not working!! I've always counted on Frontline for my pets. And now for some reason it's not working. It's made my pets itch more. What's going on with the product!!??? It's making me very upset & angry.

I have been a Frontline customer for many years. A couple of months ago, when my pets got a few fleas, I bought Frontline as usual and applied it. The first application didn't work. The next month, I bought a new box and applied it. NOTHING HAPPENED. It didn't kill any fleas at all! By this point, my poor animals had a terrible infestation, and I had to buy another brand of flea prevention, which worked just fine. One of our cats developed anemia from the infestation and ALMOST DIED. I am very disappointed in Frontline and I will never buy it again.

We have 2 dogs and 2 cats. Used Frontline for 2 years and it worked wonderful. This year it is not working at all... My dogs and cats are itching with fleas. I would like to know why this year it is not working?

My husband and I have a sweet little Dachshund named Pete. We have been using Frontline for 2 years and felt it was working well. Over the weekend my husband was sitting with Pete on his lap, got up and was covered in fleas. We checked Pete and he too was covered!! The product was applied as directed and we keep a paper log of what time and who applied it. Nothing had changed other than it's not working. Our home is infested. Because we trusted this product in the past we never thought that Pete might have gotten fleas. So far we have spent close to 600.00 dollars trying to rid ourselves of this infestation!! My recommendation to anyone thinking of using this product is DON'T. You will be sorry. Also I cannot give it any stars. I am so angry!!

i used Frontline for my cat & now he has broken out & losing his hair. He won't play or eat. This product needs to be taken off market. My cat was normal 'til I put this on him. I'm pissed off.

This Frontline did not work. I used Frontline for three cats and two dogs, this is the first time it did not work. Do you know how stressful and expensive it is to deal with fleas in an apartment? Where is the class action lawsuit against this company?

Does not work. Put it on my dog a week ago and he is covered in fleas. Don't buy!!!

Frontline is a product that is being deliberately sabotaged and is just in the business of taking your money and funneling it to some sick cause. Have spent 100s of dollars on this product this year with NO relief. Called the company and they could give damn. Said it wasn't a "repellent". Ok then wtf exactly is it? DO NOT BELIEVE THEIR LIES.

On June 20, 2016 we gave our 7-year old 16 pound Pomeranian-Shitzu-Poo blend a dose of Frontline Plus, following the directions explicitly. Pixi was fit as a fiddle and very playful and energetic when we applied the dose. We live in Houston, Texas where fleas hold conventions. We had used other brands of the on-spot medicines before, with some side effects noted, such as lethargy, diarrhea, and vomiting and did not like the idea of taking a chance with this medicine again, but the fleas declared war and we had to do battle.

Frontline Plus was applied to my dog and I could tell he was in pain. Within 15 minutes he was bleeding directly from the application site. I immediately scrubbed him down and hopefully all of it came off. I'm taking him to the vet tomorrow. My poor dog. :(

April 4, 2016. My cat had his annual check up. I purchased the Frontline (FL) (as usual). We use it for the spring/summer months (Spokane, WA). Vet said to wait 2 days before applying due to other vaccines at appointment. Applied 4/6/16. Within a week my two small children were covered in flea bites and there were jumping bugs everywhere! Did ENORMOUS amounts of laundry - curtains, area rugs, clothes, bedding, linens, etc. Vacuum 1-2x day. Called vet, said it should start working soon. Told neighbors to exam their animals just in case. One neighbor said FL was not effective anymore per her vet. Read the reviews on this site to confirm. Call FL directly: told me they wouldn't refund my money unless I had used a 3 month cycle. I do not consider 3 months 'fast acting.' On box it says: "Kills fleas, flea eggs & larvae, ticks, and chewing lice. Fast Acting, Long Lasting, Waterproof."

I noticed my 70 lb dog scratching, like he had fleas. I have been using Frontline Plus for years on every animal that I have owned. I checked him and he had fleas. Use it monthly so there is a problem with this product. My vet said it had been a problem for 4 years.

Biggest mistake of my life purchasing Frontline plus for my 2 spaniels that we take hiking. Ticks can be a problem in Oregon so we thought we would try the product. Within moments of applying both dogs eyes rolled back in their head and they collapsed to the floor unable to stand on their legs. The vet was called and we were told to use Dawn Dish soap and water in the shower to get it off because it cuts through the oil product. Both dogs had neurological damage. The 12 yr old died within 30 days. This product and other brands like it need to be taken off of the market immediately.

After reading the instructions for administering Frontline Plus to my 8 year old male cat. He has become lethargic and frightened by the smallest events. Three days now and tomorrow I will bring him to the vet. Awful product! Hard to believe with all of the horrible reviews (which I read, today) that this item hasn't been removed from market!

I had used Frontline on my lab for nearly 7 years and Monday I found out through a CBC by his Vet that he tested positive for Lyme disease. I cannot believe this company could be so greedy to make us believe their product is as good as their claim. I will be taking this to my local state rep, atty general and let them do what needs to be done to stop these false claims of this BAD drug.

I am a Pet Groomer with 28 years under my belt. I started grooming there was no Advantage or Frontline. My Vet gave me a gentle flea spray with Pyrethrins as its main ingredients, with no long term flea or tick repellent. Then came Advantage 1st, it was a blessing with my customers' pets as well my own. Then late 90's Frontline and later Frontline plus for dogs like mine at the time who had allergies. Now 2016 still grooming and most of my customers are using a pill from their Vet. I believed in Frontline Plus and with a recent Chihuahua rescue who happens to be allergic to flea bites, nothing is working. Gone from Frontline Plus to Advantage II. :( All that's left is K-9 Adv, or the pill from the VET and a Vet bill. What is going on???

I've poison my cat with this product for many years. Every fall we have issues with fleas but this time is crazy. I discontinued this product because he had a terrible rash for two years and started to bleed and still we have fleas and my kids are getting bitten by fleas all the time. I bought a collar the other brand. But finally he has no fleas and no my awful rash. He has recovered. Sadly my house well after two toxic flea bombs (Shot Bed BUG/ flea) We STILL have fleas. I spent so much time and money and still can't get rid of them.

I have 2 indoor cats that never had fleas. Rescued a puppy early Dec 2015. Noticed all 3 of them scratching with fleas. Applied Frontline Plus exactly as instructed. No prior bath or immediate bath after applying. Within a week they were infested! Used a nit comb and couldn't believe the amount of live fleas and flea poop in their fur. Took all 3 to the vet and was given oral medication. The cats vomited the medication so had to apply Frontline Plus again for second month. A week later the fleas are still on the cats as if nothing was applied and you can still see the area between their shoulder blade where it was given appropriately.

I have used this product for years on my cats and dogs. I have spent a lot of money as most people have on this product. We are down to only one dog now and I found that Frontline does not work. I have to give the dog a bath to kill the fleas. Yesterday I killed 5 fleas during the bath. I want a refund and I want it now. Tom I will be contacting the NYS ATTORNEY GENERAL'S OFFICE AND FILING A COMPLAINT.

I purchased Frontline from my vet. I was told it would only be guaranteed if purchased from a vet. I used it every 30 day for 4 month on all 7 of my indoor cats and it didn't work at all. I did everything that was needed. I washed bedding every 3 days and vacuumed every 3 days. This medicine does not work on fleas at all. I then went to Frontline website to see what I can do for the guarantee and was told it won't help me because I have more than the allowed cats. I am very disappointed in this product and will never use it or recommend it to anyone.

Switched from Advantage as we were pulling ticks off the cats daily and now all three animals have fleas after applying Frontline. After nine years flea free I am appalled Frontline is still being sold. I have been using it for 3 months consecutively and after reapplying 6 days ago, the flea infestation is getting worse instead of better. This product should be banned.

I used Frontline for 8 years to kill ticks on my indoor/outdoor cats. In October 2015, I found live engorged ticks on my cats after administering Frontline. Previously, the tick would have been shriveled and dead, if still attached. So not only do my cats hate the administration of Frontline, running away, frothing from the mouth, but the last batch is not effective. Good Bye, Frontline.

Used this on my cat for years, no problem. It did the job. Until the last couple of months. It stopped working in its current format, or did it. I tested by smelling, 2 different packets of the product were tested this way. Pack 1 was definitely less pungent than pack 2. It smelt watered down. I complained they sent me more for free. That didn't work either. Goodbye Frontline!

Have been using Google Frontline plus for over 3 months now and it's like I'm not using anything on my dog. This product is not doing anything it claims to do. This was the first time I have used Frontline on my pet and will be the last. I have been unable to contact Frontline at all. They won't return calls or messages. They have blocked anyone from commenting on their Facebook page for this very reason I assume. Do yourself a favor if you're reading glasses this and go with K9 Advantix or some other product. Water works better than Frontline.

I have been using Frontline for the last 6-8 months. My cockapoo has skin allergies, so I thought that this is why he chewed a 5" bald spot on his back. He's done it before. Took him to get groomed today, and the vet called to say he has one of the worst flea infestations she has seen. Huh???? But I am using Frontline. Silence from the vet, then she said, "Frontline is the problem." What?? Apparently, Frontline can become ineffective? How can this be? My vet has quit selling it at their office because of the issues they have seen. I just wish I had known about this sooner.

I rescued two kittens and have treated them with the Frontline Plus product purchased from BudgetPetCare. All was well for the first six month supply (three months for two cats.) My next six month (three month per cat order), my cats have gone out and returned infested with ticks. Not dead ticks, but thriving, alive, filled with blood ticks. (They are outside for a two-hour period of time!) As a long term cat owner, I have used Frontline for decades. I have never seen such an epic fail from any Frontline product, as I have from this batch. I seek a replacement with a new batch, or a personal daily "tick remover", which I have now become.

I bought Frontline Plus from the vet for my dog's flea problem, but it was only one dose. I put it on him, and over the course of three weeks I watched the infestation get even worse. He's been biting his skin raw, scratching himself until he bleeds, and I have to bathe him every day to drown any fleas on him. Frontline Plus has done nothing as there are even more fleas laying more eggs, and it is unable to kill them fast enough.

I purchased a year worth of Frontline Plus for Cats at the local Pet Smart store in Everett, WA; 6 months into treatment and my cat who is 12 years old still has fleas. This product did not kill fleas, flea larva or chewing lice as the product claims to do so. I want my money back, ALL OF IT...

Frontline used to work for protecting our dog against fleas and ticks. Last spring I noticed numerous fleas and ticks on him despite proper application. When I called the company, the person I spoke with kept making excuses. I waited a month and lived with the fleas. Again, I applied a dose of the product and it did absolutely nothing. Again, the company spokesperson was defensive and not taking responsibility for the product not working at all. Again I waited a month, not wanting to double up on toxins. Advantage still seems to work - as does flea combing, diatomaceous earth and vacuuming!

3 days ago I purchased Frontline Plus for cats. My boy is a 2 1/2 yr. old Snowshoe. He's amazing. Well, he was... My boy now, is as if he had a frontal lobotomy. I wish I weren't alive. I just got off the phone with Merial, company in GA. that makes Frontline. They asked me a few questions about the packaging. The product I purchased, from a pet store was a BOOTLEG product!!!!! PLEASE DO NOT BUY MEDICATIONS FROM ANYWHERE EXCEPT YOUR VET!!!! I am going to my vet right now... Please pray for my boy. As I will pray for your babies too.. I AM SOOOOO SORRY.

I have 3 dogs, 3 different sizes and have called Frontline twice in the past 4 months to find out why I have fleas everywhere. The first time I assumed someone had bathed one dog within 24-48 hours of treatment so I waited 3 weeks and reapplied. Absolutely NOTHING got better. Called and they told me the fleas had laid eggs but now that all 3 dogs were treated we should be fine. 3 weeks later and things are worse. Called again and they just repeatedly told me that Frontline is not a repellent so there may be fleas but they will die in day.

I first used Vectra 3D per my Vet whom insisted it was top of the line and "amazing". My dog is two years old never had a flea in his life and 24 hrs after use, broke out in hot spots and the medicine apparently seems to have drawn fleas to him! Mind you he has never had a flea bite or flea in his life! We travel a lot to parks and fields, my kids are active athletes. Anywho, I switched to Frontline. So far it's only been two hours but no hot spot or weird behavior as of yet!

What a totally useless product and it should be banned. Purchased as tick season has started again and used as per instructions. Took my small Sheltie for a walk 6 days after applying FRONTLINE and that night, had to rush her to an emergency vet as she had started having problem with her back legs. Her lovely coat had to be shaved/clipped and she now has to wear a coat to ensure she does not get cold. And now 5 days later, a VET bill for THOUSANDS of DOLLARS. I may be able to bring her home tomorrow. How can these people state that this product is for "the prevention and control of ticks including paralysis ticks" on the front of the box when clearly it does neither and so puts the lives of dogs at risk?

Very underwhelmed. I used to use Frontline Plus and it worked well but switched to Advantix because it doesn't work on mosquitoes. Went back to it this last month and my dogs still have fleas as well as me!!!! At least now. Just ridiculous that their customer satisfaction is not paramount. I'm going back to Advantix. Frontline used to cutting edge. Now it's not even marginally effective. Do not buy under any circumstances. Lesson learned.

I wish I had found all these reviews before wasting $40. I bought Frontline Plus for my dog because the store I went to didn't have any Advantix II, so I figured this was the next best thing (being the 2nd most expensive). It's been a week now and my dog still has fleas. She has welts and scratches all over her from the biting and itching. Now I'm fighting a flea war before it turns into an infestation, since I have to wait 3 more weeks before I can give her another treatment. Horrible product. Do not buy.

I treated my dog with Frontline plus & the product does not work. I treated her a week ago - now that are all on her. I called to take product back to Wal-Mart & they refuse to refund or exchange for Advantage. This is ridiculous & seem there is nothing being done about this product.

Took my two cats today to the vet for a health certificate which involved getting Frontline. It went fine until 2 hours later. One of my cats went crazy, vomiting, frothing at the mouth and running into walls at full speed. It was horrible! I rushed her back to the vet and they placed her into a warm bath and washed off the Frontline chemical. The vet had told me they have never seen such a reaction to the product. They even called a rep from Frontline to come into the office. In the end all was fine, but I will NEVER, NEVER use this product on my cat again!

Rico scratches more one week after application than he did before the application.

I have cats & dogs. I applied Frontline Plus to them the 6th of Sept and they are COVERED in fleas!!! I have NEVER had this issue with my animals before. The cats are inside and never go out. What gives? Has this product changed? I would like my money refunded if so as it costs A LOT to flea treat my 5 fur babies.

FrontLine Plus- Dogs 5-22lbs - I was unsatisfied with the product, so I called the number on the back of the box under the Satisfaction Guaranteed logo. I was then rudely told that since I had not foreseen this problem and saved the receipt from when I purchased the product, I was not eligible for the Satisfaction Guarantee. I will not be purchasing anymore Frontline products in the future, and I would not recommend it to anyone else.

I wish there was a zero star option. I have two cats, both 15 years old. We had a flea issue last year. Used Frontline, and the fleas were gone. This year, I am lucky if Frontline worked for more than 24 hours. One of my cats started getting bald spots from all the itching, but we were under the impression it was due to old age. Oh no. He is now severely anemic because the treatments to kill the fleas with Frontline was like blowing air on my cats' fur. I am combing and washing HUNDREDS of fleas off of him and his brother a DAY.

I have used Frontline for years and I have loved it but the last 2 boxes I have got didn't work! Did you change your ingredients? My dogs still have fleas and I can't put anything else on them because I am scared it will hurt them since they already have medicine on! I guess next year we'll be trying something else...

I have applied Frontline for two months in a row. My cats continue to have fleas. I comb every day and take tons of living fleas off them. I completely angry and upset at the same time. One of my cats seem to have the worst of it. He has all kind of scabs around his neck and when I comb him not only do I take off fleas but also dried blood. My oldest kitty is sick and I begin to wonder if it from the Frontline. Why do they tell you have to wait three months before you can file a complaint or dissatisfaction.

I can't be so displeased with this product. My Scottie has had developed skin irritation and it has been over month and she has lost almost all her hair. Her hair started to grow back but she has been chewing and scratching her skin and it hurts for me to see her suffer. I have a boy dog also but he was not affected by this medication. I wish I never have used this product for my girl dog.

My cat Jazzy after using this product had intensive scratching that led to bald spots and vomiting. If you feel as passionate as I do about your babe's please do not use this product. I tried to call Frontline and they had no answers for me. But I did get a case number.

Early in the morning on July 13, 2013, after having given Rudy Frontline Plus the night before, he had a grand mal seizure. I was so scared and upset. I thought I was going to lose him then and there. After about 5 minutes, it seemed like an hour, he got up rather dazed and then seemed fine. I called the vet right away and got an appointment. Having some time, I went on the internet to research and found many articles on the side effects of Frontline Plus and many of the people reporting their pets had seizures. After many tests were done at the vets, all the results came back negative. I asked him if it could have been Frontline Plus that caused it. He said no as Frontline was a safe drug. He has since changed his mind. Well that day was just the start of the seizures.

I recently purchase 2 lots of 6 applications of Frontline Plus to keep my 2 cats free of fleas. The results have been unacceptable - useless in other words. I have been using the product for year. My cats are kept inside and not exposed to other animals and have never had fleas until I recently moved. No response from the manufacturers even after 2 telephone calls. DO NOT BUY THIS PRODUCT IF YOU EXPECT TO KILL FLEAS. I'm trying Purina Total Care. After 3 days, it seems to be working.

As far as the product itself it appears to work as it should. The other day while preparing to put on my dogs I set the product container down on my dresser. The vial was leaking and got on my dresser. I hadn't noticed and in a while I came back and saw that it had dissolved through the finish on my dresser. I tried to wipe off but the chemical reaction caused it to become sticky and ruined the top of my dresser. I called Frontline to see if they had any explanation as to why this occurred and they could not offer any explanation. Nevertheless, it has left me wondering what this could be doing to my dogs!!

This is the second time using your product. It's crap. Do you only use it to keep little green men away in America, i.e. men from Mars. Won't be touching it again. Our dog does not deserve this.

I've used Frontline Plus for three years now. But when I purchased my last batch, the product did not work. My cat is covered with fleas and is suffering. I applied the new Frontline three months in a row. The first month, fleas were gone for about a week. The second and third month, the fleas didn't go away at all. I can't apply Advantage until the end of the month. Meanwhile, my cat has stopped being affectionate and constantly scratches and shakes his fur.

LUBBOCK, TX Resident wonders why Frontline hasn't not been pulled off LOCAL the shelves? Please SPREAD THE WORD so others do not have to continue to suffer! 16 HOURS after application with NO IMPROVEMENT. Not only did Frontline NOT WORK, ONCE I APPLIED Frontline made our oldest pup completely pass out. Then our second younger pup started not acting himself, staring off into space, then passed out, falling asleep, only to wake up the next day in the same amount of infestation. PETS are still infested and it says to only apply such product once every 30 days. WHY??? I am really concerned causing me distress if reapplication of an alternative product is going to hurt my dogs.

Always used Frontline as recommended by my vet but this year it did not work. Went to Pets At Home and asked the vet. There she told me that the fleas have became immune to the product and recommend Advantage which worked immediately. Why are they still allowed to sell Frontline? It's fraud.

Pretty expensive. But it is not working. Fleas are jumping not dying. Wasted money. Frontline Plus for cats for fleas and ticks. Now what can I do without poisoning my cat!!! And our family and home.

I have had my cat for 10 years, he is an indoor cat. Last summer I used Frontline on my baby. A month later he began scratching and biting his hair out in big patches. He got better a few months later and I thought it was just where he had made his way outside and got fleas. And now this year when I treated him once again with Frontline here he is again, bald and scabby all over. I just cry and cry every time I look at him. He is a big part of our family and this is so heartbreaking. I see many others have had the same problem once I got online researching it. Can we not start a class action LAWSUIT against Frontline? I'm sorry but he is like a child to us and it hurts me so to see him suffer like this over a medication that is suppose to protect Him, not HARM him!!! I am attaching a photo of him before Frontline and one after... Now you tell me how cruel this medication is to our fur babies...

We went on vacation for 10 days and my mom bought Frontline from Costco - a pack of 6 for $60, a great price! She applied it to our kitty the first day we were gone (and she's very adept at it, having had dozens of dogs and cats over and the years) which was July 27th. At this point, Scratchy didn't have any fleas (that we knew of) as she's an indoor cat. We bought Frontline to protect her from potentially getting fleas from my mom's dog Bubbles, who is basically an indoor dog, but goes outside for walks. Bubbles had a few fleas, but apparently it was under control. She gets groomed and also my mom purchased Advantage at a local feed store where they sell other pet items. WELL... those fleas jumped onto poor Scratchy and despite the application of Frontline, we've been combing approximately 100+ fleas off of her DAILY. Sometimes more hatch in the afternoons and she's got another 25 or so after a FULL combing!
