I purchased 2 collars for my girls here we are 2 weeks later they are still itching and scratching and biting the damn fleas we even sprayed our yard did we get a bad batch NEVER AGAIN!! $130 Wasted thanks for NOTHING
My cat has had fleas for couple of months I have been using bob Martin products,they just got worse ,so last ditch attempt I purchased seresto collar for 40 pound within two days not a single flea on him or anywhere else ,it's like they just packed up and moved out ,so thank you seresto 😁
DO NOT BUY the collars for fleas and ticks my cat has no fur and has sore all around her neck after wearing a few months. They may well work on killing fleas and ticks but not at the cost of causing so much damage to my cats neck and fur its toxic!
I paid 54.00 dollars for this collar and I’ve already pulled two ticks off my dog. Will not buy this ever again.
Vet provided a collar for my cocker. Within 24 hours she was scratching and licking. Then her eyes swelled up and were nearly closed. Took her to vet who gave her antihistermines her eyes are better but still itching and scratching . Never again .
Used this product last year on our 45kg dog and it worked perfect in Eastern Europe, sorry to say this year in the same environment it has been a Big disappointment, last season not one tick, this seasons ticks filling up with blood, my dog has had a serious blood infection in the past from ticks so to say I'm really disappointed with this seasons collar is an understatement.
my dog still has flea 4 weeks after putting it on cost £38 complete waste of money
Seresto Flea and Tick collar. My dog has been wearing this for 18 days, during which time he's had a total of SIX ticks, the first one being within 2 hours of him wearing the collar. A refund has been refused as the item has been used...and yet it doesn't do what it claims to do, which can only be discovered when the item is used? It's not like it was the wrong size or colour, just that it simply doesn't work. Absolute waste of money.
We got this for our dog this past weekend and we wish we hadn't. It has made her kneck very raw and bloody. I do not recommend this product at all for any dog.
SERESTO IS DOES NOT WORK.I DO NOT RECCOMEND!!! my small dog use 2 weeks long time,but i found 3 tick today.
I have been using Seresto collars for years on my dogs. I have never had a problem with the collars. I love that I can put them on my pups in the spring and they last through the fall. I recently had one of my dogs lost for 2 nights, running through grassy fields. When we found her she had approximately two dozen DEAD tics on her. They were super easy to pull off with tweezers.
The dog collar is meant to repell fleas for 8 months. It is expensive- over €40. This is the second time I find after 4 months my dog is scratching and he has fleas.
They are fake collars??? They don’t f F ing work!!!!???? DONT BUY! They are a scam
Let me tell you, I absolutely LOVED the collar! It knocked all of the fleas off my cat, and the best thing is that my cat wasn't the one wearing the collar... my dog was lol. Needless to say this collar is a hit in my family

Avoid and stay away from that Edit 25th of December 01.46AM... Still can't sleep after loss of my family member.... Please do not buy this collar ever for any pets.... Stay away from this poison. Bayern been sued by hundreds of people because of that. FOR THEM ONY MONEY MATTERS!!!
I have a 5 year old cat. She has always been very healthy. I put a Seresto collar on her for the first time im late August. She gradually got sicker and sicker. I took the collar off. I kept taking her to the vet and they could find nothing wrong. 3000.00 later she is still ill. Please be careful with these things!!!!
I've justcrecently bought these collars for my dog and cat i am really pleased with the results had an huge problem with fleas due to someone's young puppy that hadn't been treated by the breader ive always used a pipette frontline and didn't work along with treating my home this has been a god send ..would definitely recommend
Have always used Seresto collars and never had a problem with them before. Spent a considerable amount of money on buying 6 of them from Pets at home recently for my dogs and within weeks , have found live fleas on them!
I would give this company no stars! Stole my money and didn’t send the dog collar. No contact, ignored my emails and never returned my money or sent the item. Absolute Scam. Avoid this company - it’s hide behind company is FML GLOBAL LLC - Total Thieves
