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

Vet-Recommended Flea and Tick Protection

Help your dog lead the pack with long-lasting 8 month protection from Seresto. This easy-to-use, non-greasy, odorless collar kills and repels fleas and ticks for eight continuous months with daily wear, and can even help treat and control sarcoptic mange and lice. Get the performance you expect from a monthly treatment in an economical collar for convenient, effective protection.

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.

Protection Your Pet Can Wear

Seresto brings convenience to every pet owner with lasting 8 month protection against fleas and ticks. Plus, Seresto works through contact which means fleas and ticks don't have to bite for the active ingredients to work. It's also available without a prescription, so it's just one less step to take care of.

A Little Water Never Slowed You Down

Seresto is water-resistant and remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for 8 months. In order to maintain an eight-month duration, dogs must not be bathed more than once per month. For dogs that swim once a month or more, the control duration is reduced to 5 months for flea control and reduced to 7 months for tick control.

About Seresto

Seresto is manufactured by Bayer, a leading name in the healthcare industry for over 150 years. Seresto kills and repels fleas and ticks for eight continuous months in one easy-to-use, non-greasy, odorless collar. It effectively kills fleas and ticks and is veterinarian-recommended, so you can feel confident knowing that your pet is getting effective protection.

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.

Does the collar have to make contact with the skin to be effective? I have a Pomeranian with a very thick coat that would make it difficult for the collar to sit against the skin.
Answer by ChewyJul 05, 2019
The active ingredients in this collar dispense from the site of direct contact over the skin. If your pet has a very thick coat, it is recommended to trim their fur so that the collar has more contact and the ingredients are able to be absorbed.

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.

Do you guarentee that this is a real seresto collat?
Answer by ChewyMay 07, 2020
We source all our products from manufacturer approved distributors or directly from the manufacturers. Chewy takes pride in ensuring that our furry friends’ wellbeing is always our top priority. We have worked hard to partner with all of the manufactures to deliver 100% authentic products.

Seresto New Collar Failed

I have been using Seresto collars for awhile now,. I recently replaced my dog Marco's Seresto collar with a new Seresto collar purchased from Chewy. I bought two new Seresto collars from Chewy late last year. I put his new Seresto collar on before a scheduled fly-fishing outing. I replaced Marco's collar April 1st, 2022 with one of my newly purchased collars from Chewy. We took a week long flyfishing trip over to the Owyhee River in eastern Oregon April 20th. Marco is a dog that's spent his entire life following me on my fly-fishing excursions. I noticed a tick on Marco April 25th, and I did a search on Marco immediately. I was horrified to find and remove 28 embedded ticks from his body at that time. I would not recommend buying this product from Chewy after this issue. Not sure if Chewy got a bad or counterfeit supply of Seresto small dog collars, but I surely do NOT trust their collars after this experience. I plan to contact Chewy and let them know of my experience. And I will use another means for tick detouring and protection on Marco.

So Easy, So Effective!

I have been using the Seresto collar for about 4 years. I asked my vet about it, and he recommended it highly. It is so easy! All I have to do is set a reminder on my phone or wall calendar to change to a new collar every 8 months. I don.t have to remember to put drops on my dog's back every month. I have not seen nor found any fleas or ticks on my dogs for years. It works!

Seresto flea collar

Very disappointed in the size. My Beagle puppy has had the collar a very short time and the collar is already to small. But the collar is still good for another 6 -7 months that doesn't do any good if he can't wear it. I have to get a collar that doesn't cost as much. I can't afford $50 a month for a flea collar. The one for the bigger dog work's great.

We always use Seresto flea & tick collar

In conversation that we were having a hard time with past products, a person told us about this product. We ordered it and have used it ever since. I now always auto ship a new collar yearly with CHEWEY.COM. CHEWEY is a dependable source for online orders as well as excellent customer service help & care.

Amazing!!!

I wanted to wait at least 6 months before I wrote my review just to make sure it was accurate. I used to have a severe flea infestation with 4 animals. We tried everything - sprays, pills, creams, liquids, anything. Nothing worked, the infestation was too far gone. So, we called in a professional. They did their magic but then a month later the fleas had returned!!! I spoke with him and he said it was probably outside nearby fleas so he recommended getting the babies onto flea meds again. SO I bought this. Within 3 days the fleas that had returned were gone and now 6 months later I've had no issues with fleas at all. I don't think you'll understand how grateful you'll be when you stop seeing fleas all just by a collar. 10/10 recommend and I'm buying my next set soon!

Not a great option for 10 month old puppies

I purchased two of these collars and they lasted less than an hour on my 10 mo old dachshunds. They chewed them off each other and ended up in tiny pieces, unable to be reused. That was $120 thrown away very quickly. I will need to go the drop or pill route for those boys.

Great Protection

Our little dog had an autoimmune disease and this was the best and least intrusive defense for her as she cannot receive any vaccines. Collar arrived quickly in the mail. FYI--I have always opened the collar bag and let it air out for a few days before putting it on her so it is a little less potent and overwhelming for her system. I heard this advice from a friend and has worked out great!

100 stars!

I've been using these for years on all my animals and still haven't had a single flea or tick on them. Even after going camping. the 8 month ticker is the longest time across all collars and medicines ive teied. no smell, no residue, worth the money!!
