Frontline Reviews

Purchased multiple boxes of Frontline plus at excessive pricing. Applied the medication as instructed. There has been no change in the rate of infestation of fleas and ticks. When calling the company the person replying was very insensitive and defensive. She gave replies with no basis in scientific fact. In reality, making things up. The bottom line is that Frontline does not perform as advertised.

My puppy started Frontline Plus when he was 4 mo. old 25 lbs. I bought Frontline Plus through my vet. He did not have fleas, but I applied as a preventative and followed the directions explicitly. He is the only pet in the household. I started to notice he had dry flaky skin which I chalked up to a dry harsh winter. Eventually, I noticed scabs on the back of his neck. I assumed these came from scratching his dry skin. After the third month of the 1st application, the dog was writhing in pain and clawing himself bloody at the spot where Frontline is applied. The vet had to sedate the dog and shave him. This revealed his body covered in lumpy, crusty scabs over his pores and a hideous oozing wound on the back of the neck. The vet asked me if I used Frontline and then the bulb went off. Merial will not honor guarantee unless it was purchased through a vet, which mine was. I called Merial and I know they will reimburse me for the Frontline. I am also seeking reimbursement for the treatment of skin reaction. I feel I have a strong case. Everyone is afraid to demonize this product, but hey, if it looks like a duck and quacks like a duck...

I have used the Frontline for 2 months now and the product is not working on my dog. She still has fleas but no ticks. And she is biting her hair off at her bottom by her tail.

I have used Frontline Plus for my two Yorkies for the past several years but last year around December, I purchased a 3 pack and it just doesn't seem to have worked AT ALL. And I'm noticing now that everywhere I go it's been RECALLED and the shelves are bare, where this product use to be. I think something is wrong with the product and no one is saying. I've wasted my money and now have to have TWO dogs treated for fleas. Anyone with a pet knows, one dog can cost a fortune and TWO can cost you damn near your first born. This is ridiculous.

We have been using Frontline for at least 6-7 years on our 2 cats and around October 2013, it completely stopped working! Both cats became infested with fleas, we continued the monthly dosage with the remaining packs but I am so frustrated with the amount of work this has caused trying to get rid of these fleas. This medication was purchased directly from SAM'S Club; therefore I would assume it was bought directly from the company and is not a counterfeit. I plan on switching brands and will never use this product again.

I bought this product and it is terrible, 3 pipettes used each time. My dog, a small Chihuahua, still has fleas crawling on him. Effective as tap water... Bought from Countrywide in Worcestershire...

We put Frontline on our cats last night. This morning one of them was dead. He was a perfectly healthy and happy cat with no problems. The only change in routine was that we used Frontline for the first time last night. We applied it as directed at approximately 9 PM. He ate and sat on my lap. This morning, he was laying on the dining room floor, dead. So far, the other cat appears fine, but I will never use this product again.

I became infested with fleas in July 13 and bought enough packs of Frontline to do 4 cats for and a dog for 3 months. Plus, flea collars, bedding spray, carpet treatment and spot treatment. After following all instructions for the products, and waiting a week, nothing changed. My animals all had fleas and were scratching. I called Frontline and was given the runaround. At one point, the woman I spoke with became so irritated, she said, that's what you get when you don't inquire about a product BEFORE I buy it. I was told I should wait the full 30 days.

Talked to a woman who just gave me a lot of BS and loopholes of Frontline. She stated that the dog should actually not be alive and walking around and then the product would work. Other than that she environmented me to death. She said that I should have bought product from vet not PetSmart. They do not work together on their Frontlline, PetSmart just sells it. I'm glad I went on this website and saw that I'm not going to go buy more Frontline from PetSmart whose associate told me - Oh yeah within 12 hrs - fleas will be gone. Who the hell knows what the hell they're talking about anyway???????? I will enter a complaint with BBB just so that other people don't get the BS...

I have used Frontline for years, and have found my dog to have problems with itchiness and scratching recently. After taking her to a new groomer they told me she has fleas. I am very upset as I take great care of her and my home. The stories my vet and groomer have now told me about Frontline mean I will never buy this product again. They are a disgrace for not coming forward and letting us know the product has become worthless. Not worried about any financial gains, but you could have saved my dog some misery. Shame on you Frontline.

I have been a Frontline Plus customer for many years. However, in the last three years, this product has (I feel) been a waste of my money. Every year it seems to be less and less successful in ridding my beloved dogs of any fleas. It seems to me that ever since they changed this product to be used every 30 days instead of (if I remember correctly when Frontline first became available to the veterinary offices) every 90 days, now you have to purchase and apply this product more often with almost no result at all. I will no longer be purchasing this product until this company can open their eyes to something besides dollar $igns and ears to start listening to their customers who are complaining again this year. If I have to keep the fleas, I will also be keeping my money!

Where we live we generally don't see fleas or ticks, due to low humidity in the desert. The past 3 yrs. we've had fleas, mostly from outside birds called Sticktight fleas. I used Frontline Plus successfully in 2012. However this year, 2013, Aug. & Sept. my dogs are scratching & miserable. The one dog is allergic to fleas & suffering the most. I have been doing Frontline Plus on both dogs every month, using as directed. I am having to carefully pick the fleas off with tweezers, then dip them in a vial filled with alcohol. We have hardwood floors & area braided rugs. I vacuum the rugs & furniture regularly. Tried calling the company several times but hung up after over more than 1/2 hr on hold. Perhaps this year's product is bad. Someone should look into this.

If I could give Frontline a zero, I would. I have been using the product for many years with excellent results. This year my two dogs had fleas. They had terrible scratching, with flea eggs on their bodies. The problem has been so difficult to treat with loss of hair and scabs. These dogs are Hungarian Pulis with cords to the ground and a lot of grooming required. To see the coat destroyed is devastating. To see the dogs suffering is even worse. Do NOT buy this product!!!!

I gave my dog Frontline in August 2013 (which I have now for several years), and two days later he became extremely ill to the point of death (and $4,500 in vet bills with no conclusive findings). Fortunately he has survived and is now back to 90% of his usual self. Not saying his illness was caused by FRONTLINE, I'm just trying to find out if anyone else has experienced anything similar to this. Has there been any Frontline recalls?

For 3 years, I have been giving my Golden Retriever Frontline and for 2 years, my Mini Schnauzer. The first year it worked on both dogs. Not one single flea and I administered it year round just to be safe. That was 2011. In 2012, I kept it going and saw a few fleas, but nothing bad. I managed to keep it under control and basically it wasn't an issue. That was 2012. THIS year, 2013, I have infested with so many fleas that both my dogs have bare spots from where they've been itching and chewing so bad.

I have been applying Frontline to my dog at work for years...12 to be exact. Last time I applied Frontline to the dog, I experienced a severe reaction with the following symptoms: hives, red face, chills, lumpy throat feeling, swelling in the hands and feet, increased heart rate. I always wash hands after the application of the product and carefully apply. A total of three reactions. I have noticed with each incident the symptoms seem to be getting much worse.... Last episode I was scared enough to actually consider a trip to the hospital! Last reaction was 2 weeks after initial application.... and all I had to do was simply just petted the dogs head.... I am now terrified of dogs. I fear a negative reaction.

I gave my dog Frontline Plus on Saturday, June 1st and by June 2nd, I noticed a marked difference in his behavior and he was very lethargic. I started checking online with other people who have had similar problems and found my dog had the same symptoms. I did contact customer service and they would give no advice as to how long to expect these symptoms to persist. In fact, they really didn't want to offer any advice whatsoever. I asked what I could do to maybe get the product out of his system and they said to contact my vet which I had already done, but my vet told me to contact customer service. I am very upset not only with my vet, but with Frontline Plus. I will never use this product again and I want to be sure others are also aware of the side effects.

We had two pregnant Great Danes and were having problems with fleas so I contacted our vet and they recommended Frontline Plus Red. Our female Gracie had three deformed puppies. Gracie has always had big beautiful healthy puppies and Angel, our other female, had 2 dead puppies and 1 that lived. The only thing we did different was use Frontline Plus Red. I would really like an explanation from someone. We have been breeding Great Danes since 2006 and nothing like this has ever happened. I have also seen postings where other breeders have been having the same problem. I think all of us need an explanation as to why this happened. Our dogs are our life and it's hard to not know how this could have happened and why.

I purchased Frontline Plus for dogs for my Jack Russell Terrier about two weeks ago. It states it kills fleas, flea eggs, larvae, ticks, and chewing lice. It also states to use it once per month, and that it is guaranteed or they will refund your money or replace the defective product. I have used this product during the spring and summer for my dog for several years; off and on I have had problems with this product.

I applied the product on my three cats. As in other complaints listed below, I still saw fleas after two weeks. I contacted the company only to hear that Frontline has to be used for three consecutive months to work. I thought to myself, "I damn sure don't want my kitties to suffer from fleas for three months!" After three months of use, they still itched. I called them back. I had to supply proof that I used the damn product! I don't mean just proof of purchase, my vet was to verify that the product was used. I sent in the receipt from the vet.

I went to the vet to get Frontline for my pets for the summer. I started to see a few fleas so I thought better get this nipped in the bud before it gets bad. So I went to Eastside Vet and paid $100 for Frontline for all my pets. Well I applied just like the instruction says to do and waited a couple of days. I noticed that the fleas were not dead, so then I called the vet. They gave me the runaround and said call Frontline Company. So I did and of course they gave me the runaround as well. And now I have to come up with another $100 for the pills.

My sweet 4-year-old Chihuahua died last week. I applied Frontline as directed on a Friday; by Saturday my dog was acting sleepy and lethargic. I bathed him with Dawn Liquid. By Monday, he was crying out in pain. I took him to the vet, and was told that he had something wrong with his neck. He was put on pain medication. A week later, he was not improving; he was walking crooked and whimpering. I returned to the vet where they did blood work. She insisted it was still his neck. This was on a Friday.

I have used Frontline Plus for many years with great success on other pets and even used it before on the current pet with no issues. I feel that the last batch I got must be defective. It burned a patch about the size of two quarters where it was applied. The groomer said she had seen other dogs this past year with the same consequences and the hair does not look like it will grow back. I am so upset.

I have used Frontline on both of my dogs for the last 3 years and in the last 6 months, it has done nothing for the fleas on either dog. I don't know what has happened or what they have done to the product but it is an enormous waste of money now and since the cost is pretty high to begin with, I'm pretty angry over it. I believe companies should be held accountable when their product isn't what they say it is so I'm warning all consumers not to buy Frontline for their dogs. I have had to switch to K9 Advantix based on feedback from friends and groomers who have had the same experience with Frontline and have had to switch as well.

After noticing fleas on one of my dogs, I purchased Frontline Plus (two boxes for my two dogs, $90). I applied it just as directed, by parting the hair and applying the liquid directly to skin between the shoulder blades. It did not kill a single flea. I could see them actually crawling in the area that was still wet from the medication. After my dog developed hive-like bumps from the flea bites and had scratched his neck raw until it was bleeding, I brought him to the vet. I was shocked when she told me that fleas have become immune to Frontline over the years. She said client after client after client comes into her office with dogs suffering from flea infestations because people treat with Frontline, only to realize it is completely ineffective. My vet bill was $200. I cannot understand for the life of me how a company can get away with charging $40/box for a product that proclaims to kill fleas, when it is apparently well-known in the veterinary world that it no longer works to kill fleas. How many more unsuspecting pet lovers have to watch their pets suffer because of a company's blatant false advertising?

For the past three months, my three dogs seem to get more fleas every time we apply Frontline Plus! I have to use a flea comb on them every time I get near them. I am going to have to call an exterminator to spray for fleas. I am getting fleas in my furniture and also on myself! For the money I have paid for your product over the years, my dogs and my family want to thank you for the fleas and the itching and extra expense we will have to pay to get rid of what we have already paid for your product! I am on disability and can you tell me where to turn for free flea extermination? I've trusted you for the flea control on my dogs and your products just get worse. I'm just itching to find out how you are going to help me.

We had been using Frontline for years. But last summer, it just simply stopped working. The thing is we didn't realize that for months and our poor dog and house became terribly infested. When we spoke to our vet, she said, "The company is aware of the problem." But they didn't take the product off the market or offer refunds, so I'm sure many unsuspecting people had the same awful experience. It took us months, countless hours of vacuuming and laundry, and hundreds of dollars of additional products to get rid of the fleas. I would never buy this product again.

We spent over $600 on Frontline flea products for 4 cats and 3 dogs. We use it every month and we shave the spots on the animals so that I know it is going on the skin. Everyone still has fleas! Now, I realize that it does not repel fleas and some may be present, but my animals are covered as if they were not being treated! I used this product last year with the same results. I thought I would give it another try thinking maybe I was doing something wrong. Well, it’s been two years of doing this and we’re still getting the same results. Don't waste your money!

My husband and I are struggling to make ends meet. We have two dogs and two kittens, all of the animals got fleas. My husband and I went to Walmart and picked up Advantage for the kittens and Frontline for the dogs. We took everything to the laundry mat to flea bomb. We put the Frontline on the dogs and the Advantage on one kitten, the other if too little to receive treatment after a long day and spending up to $200 to get rid of the fleas. They are now worse than ever. Our littlest kitten has to suffer until she is old enough to get treatment. Not only did the Frontline not work, but it has gotten so bad our animals got tapeworms from the fleas so we had to go and spend another $200 on worm treatment.

I followed the directions for Frontline on a cat. I bathed the cats, waited till they're dry, and applied the product. It has not killed 1 flea. I spoke with 3 vets. I need to wait 24 hours before application after bathing. I requested product replacement, and they said no. I spent $100.00 for nothing due to poor instructions.

I ordered $147 worth of products off their website over a month ago and they didn't deliver the products, but took my credit card payment. There is no way to contact this supposed company for they do not answer emails nor do they answer their phones. After ordering online from them and not receiving my products, I started investigating and found that they have complaints all over the web about taking people's money but not giving people what they pay for. I contacted the BBB and filed a complaint and they emailed me and told me that the company went out of business.

I made a purchase and never received anything, confirmation number or product. I contacted them and got a machine. I contacted by email and got an automated response. This appeared as the actual site for Frontline flea and tick med by Merial, but it is not. I have contacted Frontline to confirm they have a Facebook account. On it, you will find many other customers who have had the same result.

My cat is almost 19 years old, and has kidney issues. I asked the vet if I could use Frontline Plus liquid for fleas, and she said yes, it wouldn't hurt her. For 5 days, she has been having body spasms, and has trouble walking. I searched the internet and found that this is commonly caused by many of types of flea control, particularly in elderly cats with health issues! I am so mad upset that the vet said it was fine to use on her, and that she never heard of any problems with this! Please let others know how dangerous this stuff is!

Despite having a bad experience with Frontline last summer, I tried it again this year.

Between my aunt, my uncle and myself, we purchased Frontline for 17 cats in total. Did not work the least bit!

I am very alarmed that there are not more complaints about the Frontline flea spray. I suspect that there is a way for the company to block any negative information given in the media. Does anyone know what the company is capable of censoring? Where are all of the notes about problems people are having with this product?

We spent approximately 180.00 on flea medicine that does not work. We have receipts and we want our money back.

Frontline refused to give me a refund despite being told that I would receive a refund after a 3 month flea cycle. Every time I called frontline they gave me a different excuse as to why they couldn't refund the product.

Started using Frontline Plus on my 3 indoor cats 6/12/10. The label states that it kills fleas, flea eggs,and flea larvae for up to 6 weeks. It also states that it prevents development of all flea stages for up to 6 weeks. Noticed lots of flea eggs and feces on a glass top table they like to lay on soon after the first application of Frontline Plus. One of my cats was spending an inordinate amount of time in the basement during this first treatment period. On 7/11 I swept some flea eggs and flea dirt from the table into a petri dish to see if the eggs hatched. Like a fool, I administered a second topical dose at the recommended four week period on 7/12/10.

I didn't even bother calling this time because of my first experience almost five years ago. I was using Frontline on my dogs and ended up with a flea infestation. Their response was that I had probably applied it incorrectly—no replacement or resolution. They were pretty snotty. I vowed not to use it again. But last year, my vet talked me into trying it again and guess what? I have another flea infestation. I've seen other complaints that are similar, so no one will ever talk me into returning to that again. $120.00 for K9 Advantix and $50 for flea shampoo and products to treat the house.

My name is Margareta **. I was the proud owner of a beautiful Golden Retriever named Kirstein and a beautiful Doberman Pincher named Naya. Kirstein was a therapy dog. (I feel was killed by chemical reaction.) I applied Frontline Flea and Tick product after giving baths.

Frontline is poison. I've stopped using it on my Zoe (Rhodesian Ridgeback) two years ago. It made her sick for three to four days after application, and weight is not the issue. The product is. I examine her once or twice a day for ticks by hand. She thinks she's getting a rubdown. It takes 24 hours before a tick releases its poison if it has any.
