I purchased the Soresto collar for my dog approximately one month ago at *** and the collar does not work. I have been finding ticks on my dog, which this product claims to protect against. I contacted customer service and was just told that it does not necessarily protect against ticks which is completely contrary to the claims. This is a falsely advertised product that I paid a lot of money to do one job. It seems completely irrational that your customer service seems to completely ignore the whole reason for the purchase of the product and told me that my calling was a waste of my time.

Hi, I recently bought a Seresto small dog Collar. After 4 weeks of use, my dog still had fleas! This was disappointing compared to my first purchase. I've tried contacting Bayer for a response with no luck. The product is the Bayer Animal Health Seresto Flea and Tick Collar for Dogs, meant for 8-month protection. I lost the box but have the pamphlet and receipt. Thanks

Bayer Advantage II. First vial from foil opened and following instructions was unable to pierce the plastic cover. Repeated, no positive affect. Repeated many times, vial would not open. Eventually had to use scissors to open. Tried expelling the contents onto cat's base of skull. Did not expell all contents even despite squeezing vial as some remaining was expelled onto our finger after checking. As there's no way to ascertain the content, we're now unsure if we have the proper full dosage or have to risk toxicity by administrating a second vial. Tried researching contact information for company and have found there is no direct contact information regarding this product, only a customer support open Monday through Friday.

My recent Seresto Collar for Large Dog Breed, is a DUD! I have purchased more than 4 collars since getting my German Shepherd.. This one however is NOT working.. I threw away the canister, So I can't return it to the store.. There's no way to contact Bayer and let them know, My collar isn't working. I simply want a replacement.. They are over $60.. and for it not to protect against the ticks is driving me Insane! It always works for us, for the past 3 years.. I think this is just an Older collar that isn't effective and since they don't put expiration dates on the canister, There's no way to really tell if the ingredients are still active. Any big business like this would simply take my problem and agree and just send me a replacement collar.. But there's no contact information for the company.. How the heck can you file a complaint?

I bought two dog collars in November . My vet gave me a rebate form for $15 each. I applied successfully but never got the rebates. Contacting the rebate center, they said they emailed the check, but I found nothing. They promised to resend it, yet now claim it expired in March, denying my rebate. This feels deceptive, as they just agreed to reissue it last week.

I purchased 5 seresto collars for my cats @ $50 each from *** near the end of July . I put them on the cats August 1st. The product is suppose to have protection for 8 months. August -yes protection September -Yes protection October- Yes protection November -NO protection December- ? January- ? February-? March-? So what am I to do for protection during and future months. This stuff is not cheap. I cannot find a phone number or email address for the company ( Bayer Healthcare LLC, Animal Health Division / Shawnee Mission, Kansas). So I am contacting you for replacement of failed products. To spend this kind of money and it only worked for 3 out of 8 months of protection. I consider this a FAILED PRODUCT. Yes I want you to forward this to the company. I want my money back or a replacement of product with guarantee of proof that it works.

I purchased 3 Bayer Saresto Collars in November from *** in Henderson ,NC. The collars are supposed to start working within 2 hours. The collars are not working to the guarantee provided by the company. I called and reported the issue and the company reported the collar numbers. They refused to back up there product guarantee and where others have received a refund AND OR new collars this company did not offer me either. Just stated they don't do this anymore. Here we are in Jan and they are still are not working and I have finally switched my dogs to another product. I have don't EVERYTHING I need to do to ensure my fur babies are FLEA and tick free. I have taken over precaution. This product is absolutely terrible now and I am very very very upset with Bayer as I have been a long term customer and have never had such unprofessional service based on a product I really thought very highly of for so long.

My dog was administered Bayer Advantage Multi at the vets office on 6/23 . My dog received no other treatment that date except having her nails trimmed and heartworm protection. She became ill over the next twelve hours and slowly began to decline. I took her to the vet on 6/25 where treatment required a cost of 300 and I was reimbursed for the other five tubes of Advantage that I purchased on 6/23. I was told to never put that on her again. We prayed she would get better but by sunday, 6/27 she was so sick I drove her an hour away to *** Emergency Care where they have a vet 24/7. She remained there and I had to put her to sleep on 6/28. This medicine killed my dog. She suffered for days and the loss to our family is terrible! I have attached the ER Vet bill and I want reimbursed. I want my dog BACK. She was like my daughter. I will not stop until this company acknowledges their product. I am very educated and I will not stop advocating until they acknowledge this.

In January, I purchased (2) of the Seresto collars for our dogs. *** is 8- a bird dog mix; & *** is a Great Dane. I placed the collars on them- excited to see how they would work. At the end of February, *** starting developing nodules, cysts, all down her back. They were all about the size of a dime. The hair would be raised and that is how I noticed some of them. Others, however I noticed due to blood being all over her back. Upon closer examination, all of the lumps began to bleed & ooze. They were painful to the touch. They would scab over and then the hair would fall out. I happened to see a concern that someone shared on social media about their dog dying- the veterinarian suspected it was due to the Seresto collar. I started investigating & was SHOCKED at the complaints. I immediately removed the collars and bathed them in Chlorahexadine to cleanse their skin! Sadie's lumps and skin have now healed. I would appreciate a response to this matter & Refund on collars!

I have purchased 3 small dog and 1 large dog Seresto collars on average of twice a year for the last 4 years and they've been great until the last 2 purchases. The collars that I put on our small dogs didn't seem to be effective for more than three months so I purchased more from two of our local stores, *** and *** since stock was low at both. These collars have not been working at all. The dogs are constantly scratching and biting themselves. I've had to resort to dipping, spraying, and bathing them in flea shampoo weekly. All three average around 10# so I don't know if bad batches have been released, or formula has changed? I have even contacted Bayer on their website a couple months ago asking for answers or help, but have yet to be contacted. I have recommended these collars to every pet owner I know since first using them. I can't in good conscience do that now. I feel I've basically wasted just over $330 on my last 6 collars. And of course I no longer have receipts because I have always trusted Seresto.

I bought collars for 4 of my pets and toys for 2 cats. I had the required tests done on all the animals. I then sent in all the required documents for the rebates. There should have been 3. A $30, another for $30, and one for $130. I only received one check for $30. The remaining two eventually came but were expired and the bank would not cash them. I contacted Bayer and asked if they would reissue the two checks totaling $160. She confirmed the checks were never cashed. She then proceeded to tell me that they are not responsible for mail delays. I tried to talk to a supervisor and was told 'there is no one higher than me and we cannot help you.' She then hung up on me! I have been waiting for this $160. I couldn't afford the collars but the rebate made it possible to get them financially. But in the end, I am not getting the promised rebate. I am very upset that I cannot speak with another customer service manager and also upset that they cannot honor their rebate as I clearly did everything correctly on my end.

I have been a avid consumer of the Seresto Collars for Cats for over 3 years. I have purchased repeatedly until this past December . I have 5 cats, all wear the Seresto collar and never had a problem with the effectiveness of them on my cats. On the lot in question , after 3 months they lost their effectiveness. My cats we being invaded by fleas. So I asked for a return to *** and they were replaced , this was in March 12 . As of the end of June the fleas are pervasive on all of my cats. t These Collars are to be up to 8 months of protection. Don't know what happened on these last 2 lots. I am completely at a lost since, since I prefer the collars instead of the ointments. Here is the initial order info.

I bought $197.00 of Advantage Multi on Nov 12, 2019 from a local Animal Hospital in Washington, NC. I expected a rebate from Bayer. Previously, I mailed the form and received a rebate, but then had to apply online. The hospital once filed for customers due to form shortages. On Feb 7, 2020, I spoke with a representative who promised to send the 2019 rebate form. I never received it, and when I called on April 7th, I was told the deadline was Jan 20th for purchases between Oct 1 and Dec 31, 2019. Despite my Nov 11 purchase, I got no rebate. I explained the situation to a supervisor, who, understanding the delay, agreed to honor the rebate. They guided me on submitting 2020 purchases. I've been a long-time buyer of their products for my dogs and hoped for an exception due to the online confusion, holidays, and my husband's health issues. The supervisor promised to consult further and get back to me within 5-7 days, but I've received no response. I rely on Bayer products for my pets and was assured by the customer service that I'd receive the form and rebate. The lack of follow-up has been stressful, and I feel they should honor their representative's word. I appreciate any assistance provided.
