Seresto Class Action Lawsuit Claims Flea and Tick Collars Injured, Killed Pets

• SusanMarch 8, 2024 at 9:44 pm

  My cat developed a solid tumor on his neck the size of a thimble after wearing Seresto flea collar for about two years. I gave him Panacur, a dog dewormer anecdotally used to cure cancer in humans. The tumor burst and healed itself after treating him with four boxes of Panacur, mixed into his food.

I didn't want to risk her getting a paralysis tick (we live in the bush) because vaccines to treat this were/are very low. I need to do more research into a natural flea/tick preventative. For now, I will love my cat for as long as I have her.....and I cut the collar off today.

  I had a 9 year old Carolina Dog. We used Seresto collars all her life.She formed a fatty tumor near her belly. A few months later the vet said she had cancer in her spleen and it spread to her liver. Sadly, I had her put down that day.

  Reading this makes me sick. I have been terrified to search the words "seresto + cancer" because on some level, I knew there was a connection.

My female developed a small lump on her chest that we are praying is a lipoma. Both my dogs were healthy prior to wearing the serestos. Something about this has been eating at me internally since my male passed. The fact that something I subjected him to could have been what took him away from me eats me alive.

  My loving cat Attie wore the Seresto collar for 4 years. She died last July, 2023 with abdominal cancer that the vet said was wrapped all around her organs. It effected her urinary and digestive systems plus more. She was only 15. I have such guilt for putting that collar on her and I miss her every day.

  My mini schnauzer had a fatty lipoma develop on her neck where she wore the collar and it turned huge and hard after wearing the seresto over it for two years we had to put her down from the cancerous tumor on her neck.

She was treated by an oncologist , who tried many chemotherapies , that helped her live for over 2 years. She died on November 14, 2022 from TCell lymphoma. She had never been sick. I feel positive that the Soresto collars created both of these incurable diseases. Chance and Dottie would still be here were it not for these poisonous collars that remain on the market. I will continue to do all I can to encourage the EPA to ban these collars in the USA!

  Our beloved dog Cole puggle very healthy after using the Seresto collar for few years he developed aggressive liver cancer died in 3days.shame in the company. How can I proceed with a law suit so the company writes the danger ingredients of this collar that kills dogs and cats. Please advise. Thank you!

  My African serval is 2.5 years young and is incredibly healthy and one of the best looking servals at their office, stated by his exotic vet. Other than the malignant tumor that is so dense and fibrous, connected to his right jugular and neck muscles and impossible to fully remove. Prognosis is 6 months and this would have never been a thing had I gone with revolution instead of seresto.

• TraceyNovember 14, 2022 at 9:48 am

  I had a bloodhound that we used Soresto collars on… she developed a tumor that was diagnosed as skin cancer inside the folds under her face… we had them removed and then exactly a year later we noticed a mass in the same area that was growing rather quickly… it was wrapped around her trachea so surgery was not an option… sadly our Sadie had an untimely death.

In the last 15 years or so I’ve noticed a significant increase in cancers in dogs, as well as deaths from cancer in dogs. My significant other and I share a beautiful Black Lab/Basset hound mix, Bassadore if you will named Jenna Fur. She has developed tumors on her body we just had a large one removed and it proved to be malignant. Jenna is 11 years old. I started thinking about all these dog cancers and I thought it must be something to do with the food we feed our dogs. Then I thought how could food be the common denominator there are so many different varieties of food that we feed our dogs? Then it donned on me how many people I know use the Seresto collars. Jenna Fur has tumors on her neck where her Seresto collar lies. Unfortunately the Seresto works extremely well for fleas and ticks. We also take it off of her during winter time, but this spring we will not be putting a new Seresto collar on her.

So we treated it with coconut oil and it healed up. Now it’s October first and my dog is currently fighting for his life in an emergency vet for the past week, test after test. The vet came back with Lymphoma. There’s a lump the size of a ping pong ball on his neck and now we’re waiting for more test to tell if he’s got a B-cell lymphoma or T-cell lymphoma. My dog prior to this heart breaking news. This last week of September went from a happy healthy, playful dog. To lethargic, vomiting, not eating, and pretty much drunk. We went to 2 vet offices to figure it out and we couldn’t pin point it think he had a stomach bug or something. But leading up to this and some research I’ve discovered it is this dreaded seresto collar. Thank you seresto for poisoning my dog and still continuing to sell this deadly collar that is only suppose to help a dog with simple flea and ticks. Praying my dog makes it through this and we have enough time to possible help my poor Koda out.

Over the last two years, she seemed exhausted while wearing it. I started reading all the negative information on the collar and decided to remove it last week, as I have had a relative's dog die from ingested flea meds and assumed there was some validity to what I had been reading. In recent months my dog has been short-winded, tires easily, and lost the skip in her step. I had her checked out at the vet's earlier in the summer but was told she was healthy other than some orthopedic issues. I took her back to the vet yesterday and saw a different provider. She has now been diagnosed with lymphoma, possibly starting in her neck lymph nodes and metastasizing to her lungs. Her prognosis is grim. She is not a candidate for chemo, so we take her home and watch her progressively get worse until she tells us it's time to euthanize her.

I had no idea about the collars causing damage! I spoke with the groomer and she said Marley was the 3rd dog this month that has cancer, of the dogs she groomed. She thought it was very strange!

  I used seresto on 2 of my cats 2 years ago and it got rid of all the fleas in the house so I stopped using it. We found out in early June that our little girl kitty (8 years old) had a walnut size tumor and lost a ton of weight with a month. We had to put her down. This decision was the most heartbreaking decision we have ever had to make and the grief on my daughters face tore me apart.

They both wore these collars prior to my learning about people having issues. I didn’t really know what kind of issues I just heard issues so I swapped to another form of flea and tick control. These big pharma companies have a license to kill because our government is in their big fat pockets. This disgusts me, A few years ago I broke my back in four places working on a drainage pipe on my property. I tried to walk home but somewhere along the way passed out from the pain. My best friend laid with me for 17 hours until I was found. I’ve never had loyalty like that from any human.

Would appreciate help with this and/or willing to provide details to beyond those listed below. We used a Seresto flea collar on our Lakeland Terrier Izzy as a preventative to guard against fleas and ticks. In Sept 2018, Izzy’s health showed signs of concern, itching, seizure like episodes,. We took her to numerous vets to get to the root cause. , By Dec 2018, after every possible test, dermatology, neurological, systemic, etc. had been performed on Izzy, at extreme emotional and financial costs. Izzy was a dead dog walking, she lost all her hair, skin was black, , could not stand or move without assistance , could only eat and drink if we used a Turkey baster for water and feed her small bites of sift canned food. She was completely emaciated. Considered euthanasia, but tried to find some place that would take her body to research the cause so other animals and owners didn’t suffer as we had. No one wanted her body for research. Miraculously, when I propped Izzy against a sofa and asked her to tell me what to do, she feebly made a move to walk?!? I maintained hope and today Izzy is still alive, has regrown her hair but still suffered with some anatomical concerns from her illness. Enraged by thoughts vets could have considered the source of Izzy’s illness as her Seresto flea collar , if concerns with toxicity of Seresto collar had been divulged to the public veterinary community. Not sure how Izzy would have been treated if this concern was known; however, it may have eliminated both the need for subjecting our dog to the trauma of various test procedures and their associated expense .

I started using the Seresto flea collars about 5 years ago and April of 2019 Nya passed away with tumors being the only visible problems and Khaleesi had a rapid advance cancer that started at her right shoulder and spread to her respiratory system and cut off the circulation to her leg causing it to swell and THE CANCER WAS SO BAD THAT THE ONLY OPTION WAS TO AMPUTATE HER LEG AND PUT HER ON STEROIDS ONLY TO LIVE A COUPLE MORE MONTHS so I chose to put her down to spare her the agony. The next day I heard about the Seresto issue with the collar causing health issues for pets and humans. I had given Nya to my Mother as a gift and my Mother passed March 8, 2019 and Nya passed the following month. Now 3 years later I lose Khaleesi to what may have killed her mother. I don't know what action I can take and nothing will replace them.

  My dog started to have seizures after wearing those flea Callers. He is still not himself! Can I join this class action?

  A month after I put this on my cat and she's developed several lumps, losing weight and won't eat. I just found this information today. I'm devastated.

  My cat developed a large mass on his side that may be sarcoma, a week after we put a Seresto collar on him. The vet says it’s not connected but I’m not convinced.

  Our beloved BJ started out having seizures. After multiple vet visits 2 years later we had to put him down because he was consumed with cancer.

To make matters worse, she was my daughters support dog and would warn us when my daughter was going into a seizure, so now my daughters companion for her health is gone!! Then today my daughter called me at work and said my pomeranian was having seizures!! She's never had them before but prior to today she has started quivering and stumbling around!! It would only last a short time and then she would seem fine!! I thought maybe something had scared her because she's had no prior health issues and she's 7!! Then today the call that she's having seizures!! We immediately took off the collar from her and our morkie, Tiko!! I am physically sick to know that this stupid collar killed our precious Aleigh, and has been making Tinker slowly sick!! Thank God I realized it before she died too, at least I am praying we realized it in time!! There hopefully will be consequences for this company and if there is I want componsated!! No one should go through this for something that is supposed to help not harm!!!!

  My Rhodesian Ridgeback/Lab has worn Seresto collar for 3 years, replacing each spring. He was diagnosed 2 weeks ago with inoperable cancer that began as a large tumor on his neck. It is rapid growing and we are just trying to keep him out of pain until he leaves us. We are so broken hearted. To think that this could have been prevented makes me so angry. Why wasn’t there warnings??????

  So very sad after seeing this warning on the news.. lost my little yorkie in Feb. this year, she was only 7 yrs old.. survived two surgeries ..one on her breast and the other was a growth in her mouth. Miss her everyday .. stop putting things on the market that kill our pets... they are our family.

He had a seresto collar for about 8 months and started having issues with his back and front legs. Seems like his legs get stiff and he can't use them, it happens daily and will happen for a few seconds when he has the episodes. He doesn't have the collar any more, the vet really isn't sure what his problem is and says it would cost a fortune for tests and is more then likely something that would be irreversible, so he recommends just treating as we go and treat any symptoms or problems that he has. I'm wondering if this could be a side effect from the seresto collar?

I then purchased it at a holistic pet store known for not using chemicals in food, etc.no one said anything to me about pesticides. My poor Lily started having trouble walking and balancing while trying to walk as if she were drunk. It happened over time and I didn't make the connection not being aware of what the EPA knew all along and didn't warn the public. Lily also had bloodwork done and suddenly had liver issues. Again didn't know why and kept checking her and her levels would go up and down. Then they went up again and the vet said she needed an ultrasound but couldn't do it for 3 weeks because the best are so overwhelmed. So I went to another vet who I had dealt with with my previous dog and they were able to do it immediately. Thankfully there was no tumor but she needed expensive liver supplements of Ursodial and denamarin. I was hopeful these would work having read about their use. During the last 6 months of her life, Lily slept in my arms at night. I was having headaches and ended up having a mini stroke Dec.1, 2020 as she layed next to me . Still didn't make any connection because I didn't have the facts. I had to put Lily to sleep Feb 15, 2021 because even after making sure she had the proper meds to help her liver recover, how could it if the collar was poisoning her and possibly me. I'm so angry that I've been consumed with trying to get the word out in the last few days after learning the truth about the harm and deaths that have occurred from this product unchecked since 2012. It's too late for my poor Lily and I hope she can forgive me for not realizing there was a connection. I hold Bayer, Elanco and the EPA responsible for Lily s suffering and death and I will not stop telling my story and warning other pet parents about the harm of this Soresto product . I've contacted the Holistic store where I bought it and they refuse to take it off the shelves. I've contacted a friend who happens to know the owner to influence her to remove it. This friend also works at the local tv station and is going to talk to the producer and top investigative journalist to see if there's a way to generically warn pet product consumers about pesticides in certain products that could harm or kill as we approach the flea and tick product season. I've also contacted Chewey co. With whom I've done a lot of business and asked them to remove the product from their websites until research can be reviewed. They were as always very concerned and took my story seriously. I know a Congessional subcommittee asked the company to recall the product and they refused but I'm not giving up. CONGRESSMAN MATT CARTWRIGHT is my Pennsylvania congressman and I plan on contacting him next. We must hold this company accountable and get this product off the shelves. I couldn't save Lily but I'm going to make it my mission to save other pets from harm or death. That's what Lily would want me to do. Please help me get the word out.
