Was a loyal seresto customer. Purchase 4 cat collars and 3 dog collars (2 small 1 large). I purchased my collars this April 2023 from both Chewy and Petco. They stopped working completely weeks ago. My great **** has flea allergy dermatitis (FAD) He's lost most his hair, his skin is puffy, he itches and cries non stop. My smaller dogs had loads of fleas upon bathing them today, can see the blood coming off their skin. My dogs get new collars every 8 months. What happened in 8 months time for these to go to total crap? I canceled my autoship with chewy and I WONT buy these ever again. The collars are garbage, my dogs are suffering and so is my wallet. They are legit collars, I got them from legit stores. They wear them non stop to the skin, never loose. They never went without a collar, wearing one all year as I was on the 8 month auto ship, I'd simply change to the new collar. I've used seresto for a few years now. I've done nothing different. The collars are just ****, not even making it 3 months with them. Never again. You lost this customer.

Regarding the seresto collar. I put this on my 10 yr old healthy lab and 5 days later he had difficulty breathing on day 7 his eye began dropping and he had a nose bleed when I took the collar off his breathing was slightly better but still not normal my vet could not determine what was wrong with him and suggested several options including cancer. He is currently on several antibiotics and after a month he is doing better his eye is more normal his nose still bleeds slightly I believe this collar poisoned him and should be withdrawn from sale too many pets have died from it and my dog is still not out of the ***** and may never be well again or die. It has been a very expensive ordeal treating him all for a $80 poison collar that was purchased from a reputable company. Shame on Bayer you should be paying my vet bills for harming my dog who is my family my other dog also started having problems breathing after 3 days the collar was put in the trash. I warn everyone now about these deadly poison collars in hope no one goes through my ordeal. Unlike my lab my other dog who is 5 finally started breathing normally after 3 weeks

https://www.seresto-store.com/ is a scam website!!!! This is not a legit Seresto website and not from the real **************** I accidentally placed an order thinking that this website and company were legit. The prices were half of what is normally offered for these collars. The website led me to make a payment thru a third party. Initially, the third party payment account stated that the merchants name was Seresto-Store and no mention of who the real merchant was. 24 hours after the purchase, I received the receipt from the third party payment account and the name listed was Xudi daily necessity store in Jiyang District, ***** City

The collars I purchased 4 total fell off of my cats after just about 3 weeks, nowhere to be found. One cat I replaced it a 2nd time and within a couple of weeks it was gone again and caused him to loose fur. 1 collar has managed to stay on 1 cat of mine, but she still has fleas!

I have used the Bayer Seresto Collar on my cats to prervent flea/Ticks since 2012/2013. I still have **************************************************************************************************************************************** the conditions as directed. Basically I was one of the loyalty customer for it. My cats were getting itching and scratching. I took them to vet with very expensive fee. I still am working with my vet for these problems. Since ********************** Report Revealed EPA Failed to Protect Pets, Owners From Dangerous Flea and Tick Collar on 6/15/2022, I am asking for a refund of unopend 10 Seresto Collars.

i purchased 4 dog and 1 cat collar and 4 of my dogs had reactions as well as myself , I had to go to the doctor and be treated with steroids for a rash I removed the collars and everyone including my self are on the mend, This wasn't the first time I used the collars , but it is the first time I have had any problems And it will be last

After putting there Seresto collar on my dog he had neurological signs that were very frightening. He couldn't hold himself up, couldn't walk straight and had difficulty holding himself up. He kept falling over when he lift his leg to urinate and behavioral signs. Head was shaking and had seizures. He has NO history of neurological difficulties. I took him to vet and first they treated him for Vertigo. No change. Had blood work and urine checked. Everything good. No change. The vet put him on antibiotics. It wasn't until I removed the Seresto collar that his symptoms subsided. The collar was the only thing that was different in his life so yes I attribute the problem was due to Soresto. I researched it and found that it has occured to many dog owners. Some resulting in death. I am requesting reimbursement for the collar, vet bills and medication I had to purchase.

Put the Seresto collar on my daschund and within hours he was dead. He was fine all morning, we put this collar on and he started acting weird, he couldn't walk, was vomiting and couldn't control his bowels. I took the collar off and gave him a bath thinking this would help but no, my little guy went from being an active, happy dog to being dead within hours. I will never deal with this company or collar again. This complaint will not bring back my sons best friend, but it will bring attention to the garbage they are doing. "

Seresto collar affecting my dog's behavior making him aggressive even to a dog he's lived with for 4 years. Started within two weeks of putting the collar on, nothing else changing besides the addition of the collar. "

Seresto 8 month flea collar made my dog lose function in her hind legs not even a hour after putting it on. Its hard to explain. Her hind legs were in the air and it looked like she was gasping for air. Took the collar off gave her a bath and now she seems back to normal. Called the company and the lady was rude! Said there was no recalls on the product and no reports of pets being sick or dying. But if you do your research there is over 1700 pets that died from this product!!! She then said if I was rude or swore she would end the call!! Of course Im gonna be rude! Your product could have killed my fur baby!!! I would just like people to know *** to use this product. And if you decide to,do your research first!! Horrible product and horrible people who work for them! Will never buy anything again that is made by this maker! And I will be spreading the word to anyone that will listen! Shame on them. Money over lives should not be there *****!!
