How do I know if the Seresto collar I purchased is authentic? It is crucial that pet owners purchase real and genuine Seresto products from authorized and trusted retailers. Counterfeit collars and their packaging look very similar to the actual product. Be sure the collar does not have a greasy feel or an odor.	Does it expire? There is no expiration date required on the packaging. The product should be kept in its original packaging and stored as directed on the label.	What are the key ingredients? The active ingredients in Seresto collars are Imidacloprid and Flumethrin: Imidacloprid to help protect against fleas and Flumethrin to help protect against ticks. No other product has this combination of ingredients.

Directions

How to apply the Seresto collar on your dog: 1. Remove the collar from its packaging. 2. Unroll the collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain. 3. Insert the end of the collar through the buckle and loops. 4. Adjust the collar around your dog's neck until it fits comfortably on them. 5. Two fingers should fit beneath the collar and neck to ensure it's not too tight. Any excess length of the collar beyond an inch past the loops should be cut off, unless it is on a growing puppy, where some additional length may be needed for adjustment as the puppy grows. 6. Check periodically and adjust fit if necessary, especially on growing puppies. 7. Seresto comes with three optional reflector clips that can be attached to the collar to help keep your dog visible at night. The reflector clips should be evenly distributed on the non-overlapping part of the collar.

Works Great, Unbelievable

Reviewed in the United States on September 11, 2023

Size: 1 PackStyle: Large Dog OnlyVerified Purchase

My medium size dog would go outside & come back in with 20~50 fleas. no ticks... we treated the yard, & we over treated it again to kill the fleas, this was working but still flea... we sprayed the house, carpet, bed, closet, furniture with flea spray for inside... we did not want a chew flea poison inside of him & the fleas will be eating him before they died... I also didn't like the idea of poison around his neck... I chose the collar over the chew...WOW in two days the fleas was fading, after the 3rd-4th day my dog was flea free. No flea in the house, or on him, he will go outside & no fleas is on him. He seems OK with the collar he does not scratch at it, he is OK with it... he is 3-yrs & never worn a collar, inside dog only...This Product Works VERY-VERY Well...we spent about $200.00 on inside flea spray, & (3) 25lbs flea yard granule plus $65.00 for the collar... My dog has been flea clear since June 10, 2023, today is Sep 10, 2023... This Product REALLY WORK, best $65.00 I ever spent...

I’ve had my dog for nearly 3 years and I’ve never had an issue with fleas until we moved into a new apartment, and then it was almost like she was infested within days. Poor girl had serious flea bite marks on her under belly before I even realized. Bought this product because of the fantastic reviews, but was wary because the price seemed steep- no regrets! I’ll be buying another in 8 months because of how easy and FAST it worked to help get rid of fleas, and also keep them off.

Fleas will die!!!

Reviewed in the United States on September 23, 2023

Size: 2 PackStyle: Large Dog OnlyVerified Purchase

Never been a fan of flea collars because of the horror stories i hear about them. A friend had one on her dog and we decided to give it a try because nothing else has worked that we have tried. Within 24 hours the fleas were falling off ot the dogs. While it is pricey its definitly worth the price because it works and has had no harsh effects on the dogs for the few months they have had it on.

They work

These are not cheap, but they work when nothing else did, when we adopted my second Boxer, he was covered in fleas, we did everything we could included a few trips to the vet, someone suggested these collars and I gave them a try, so far they seem to work, every once in a while I will still find a random flea, but compared to what I was dealing with a month ago, I am honestly impressed with the results...I will be replacing these every 6 to 8 months and hopefully they will continue to give me the same great results...

The ONLY one to use

Reviewed in the United States on September 26, 2023

Size: 1 PackStyle: Large Dog OnlyVerified Purchase

Long lasting, never had a problem with fleas so far while using Soresto. Tried a cheaper brand in the past and as my dog is susceptible to seizures my vet said that the cheaper brand was adding to the problem. Immediately took her off of the cheaper brand and never looked back. Soresto is the only brand I will use.

Great but could use just one change

Reviewed in the United States on August 6, 2023

Size: 1 PackStyle: Large Dog OnlyVerified Purchase

Twice a year I trust in Seresto to keep my house (and animals, including cats and dogs) clean of ticks and fleas, and it's literally never let me down. Despite 2 dogs and 5 cats who spend time both indoors and outdoors, not a single tick or flea has ever come into my house attached to one of my pets. That's why I trust Seresto every single year.

There is one thing I wish they'd change, though, and I understand why they won't. In the past three years of having approximately seven animals who wear Seresto collars, they've gone missing about four times. I know my one dog likes to pull it off of the other dog, which is super annoying. Plus, at $50ish per collar, it's expensive to lose. So it's frustrating that there isn't a better method for keeping the collars on. I understand why they don't put an actual clasp or buckle on it: it's supposed to slip off in the case that it gets caught. But, still, at $50/pop, I hate it when a dog or cat comes back inside and it's missing again.

Other than that -- and, like I said, that's probably four times out of around 30 collars I've bought in the past few years -- they're great, and that's why I keep going back to Seresto each time.

Works great as long a flea population has been irradicated

Reviewed in the United States on September 22, 2023

Size: 1 PackStyle: Large Dog OnlyVerified Purchase

We had used this collar some years ago, but ended up changing to Bravecto because it seemed to quit working within 5 months. However, that's an expensive prescription, so we decided to try it again.

To help, we're now treating our carpets with a product that inhibits the growth cycle of the fleas around the house and yard. So far it's working two months in. Neither dog has had fleas return.
