Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

About Seresto

Continuous Release for Long-Lasting Prevention

With Seresto, fleas and ticks are killed and repelled through contact, with no biting required. The active ingredients stored within the collar release in low concentrations with daily wear and distribute over your dog's skin and coat from head to tail for effective coverage. As the active ingredients wear off over time, the collar continuously replenishes the skin and coat with a new supply, for 8 continuous months.

Why Choose Seresto?

The veterinarian-recommended Seresto collar is non-greasy and helps avoid the inconvenience of applying monthly treatments. If fleas and ticks are repelled, they cannot bite and transmit dangerous diseases. It also helps to treat and control sarcoptic mange and kill lice. Seresto also doesn't interfere with your dog's regular collar and can easily be worn simultaneously.

Questions & Answers

34 Customer Questions

Does the collar need to be on the skin directly or does it work if it sits on top of their hair? In other words, do I need to shave their necks before applying the collar, & then repeat as necessary as the hair grows back? One of my dogs has thin hair around his neck but the others is thick & curly

What is the expiration date?

Can my dog sleep with me while wearing the collar ?
Answer by ChewyJul 13, 2018
It is safe to allow pets to sleep in bed with you while wearing this collar. The active ingredients spread from the site of direct contact over the skin surface, so it is not recommended to continuously touch the collar.

Can this collar be worn alongside or under another, regular collar?
Answer by ChewySep 14, 2018
This collar may be worn in addition to a regular collar. It is important to make sure the other collar does not interfere with the Seresto collar as it needs to remain in contact with the pets skin to be effective.

Great protection from flees & ticks

I found this product several years ago after my dog brought flees into our house and infested my 3 indoor-only cats. It was a nightmare trying to get the flees off my pets and out of my house, but once I did, I needed to find an effective peoduct to use to keep them off the dog. After reading many reviews of this product and hearing some horror stories of pets who mysteriously died after their owners used these collars, I was initially scared and skeptical. But after doing some further research and speaking to my vet, I chose to use this flee & tick collar. I have zero regrets. It has worked reliably year after year and kept all my pets safe and healthy. I cannot recommend this product enough. I encourage anybody who may be skeptical or fearful about it to discuss it with their veterinarian.

Great product for our fur babies

After reading many negative reviews on this product I’m totally baffled at what could be going on and hoping that I don’t get some ineffective collars at some point. I’ve been using Seresto on my dogs for over 15 years and have had nothing but positive results. We take our Pomeranian to be groomed every 5 weeks and our 2 long haired Dachshunds every 10 weeks. Our groomer has never found one flea on any of our doggies so far. We do keep a close eye on them due to the stories we have read about pets that suffered bad side effects from the medication. It’s heartbreaking to read. I don’t think the cost of Seresto is any worse than other products because we get a good 8 months use out of one collar. Topical applications didn’t work well for us since one of my dogs always managed to go roll in some dirt because he didn’t like them. Washing the cost of those drops down the bathtub while bathing him almost made me cry! I sure hope that this continues to work so well for us and many others.

Seresto collar

This color is a bit pricey. However the initial results seem to be encouraging I have noticed my dog is no longer itching or biting at his paws and that was my hope when I purchased this

doesn’t work

I’ve used this product in the past for my pets, but my most recent collar change resulted in a flea infestation. Customer support said this is normal, and to wait 3 months to see if they start working. The warranty is BS, they will not honor this product.

Would not recommend

This is the second year that these collars have not worked for my two small dogs. They are scratching constant and covered in fleas. One is currently getting a flea bath. I do not get the collars wet which was my recommendation from chewy. I take them off and put back on after my dogs are dry. This much money to continue to battle fleas

Great Collar

This is the third Seresto collar I have used for my little chihuahua. I have tried other collars and they didn't work. I am very cautious with my Cocoa as he's sensitive and with him being so small I don't want somethimg that can kill him. I have heard too many horror stories from other pet owners that their pets have died from flea and tick products. My Cocoa don't like pills so I didn't want to go that route. My Cocoa's old seresto collar gave out and he got fleas. I bought another flea and tick collar and there were still fleas on my baby. So. I invested in another Seresto and he's wearing it, and fleas started coming to the top of his fur dying. Although; Seresto is expensive, it's worth the money to me.

Check the expiration date

I ordered two cat and one dog collar. My cats have zero flea issues. The dog however does. I should have been more mindful and checked the expiration date. It’s been a few weeks and despite the collar being applied correctly, I’m still finding a few daily. Just a reminder for others to do so after receiving their order.

Stopped working

After years of using Seresto collars, I will never buy again. Found numerous fleas on our dog. Collar isnt expired for another 3 months. Time to find an alternative.

Flea and tick collar

My dog is very picky. Won’t eat the Frontline Chews for flea and tick, so I had to resort to a collar. It seems to be working. Who can tell? It’s odorless and non-greasy. She does not mind the extra collar on her neck so I’ve got my fingers crossed. It seems to be working; no scratching or sign of any fleas or ticks. Have not had her groomed yet so I’ll see how that turns out. It is supposed to be waterproof with no need to remove. So, three weeks into its use I would say it’s effective and I’m giving it a thumbs up.
