Seresto® for dogs kills and repels fleas and ticks for 8 months in an easy-to-use, odorless, non-greasy collar. With Bayer's innovative Sustained Release Technology, this revolutionary collar offers hassle-free, continuous protection from fleas and ticks.
Seresto® is a unique polymer matrix collar that offers a continuous supply of two active ingredients: imidacloprid and flumethrin for effective 8-month protection against fleas and ticks. That's one convenient, non-greasy, odorless flea and tick collar instead of 8 monthly treatments.
The active ingredients are stored within the collar. They are released in low concentrations and are distributed over your dog's hair and skin surface. As active ingredients wear off over time, the Seresto® flea collar for dogs continuously replenishes the skin and hair coat with a new supply of active ingredients. In fact, fleas and ticks are killed through mere contact (No biting required).
Long-Lasting: Repels and kills fleas and ticks for 8 months
Fast-Acting: Kills fleas on dogs within 24 hours
Quick-Tick Prevention: Prevents tick infestations within 48 hours
Multiple-Tick Protection: Repels and kills deer ticks, American dog ticks, brown dog ticks, and Lone Star ticks
Fast Flea Prevention: Existing fleas are killed within 2 hours and new fleas repelled before they lay eggs
Home-Protection: Seresto aids in control of flea larvae in the dog's surroundings following contact with a Seresto-treated dog
Continuous Protection: Bayer Polymer Matrix ensures that both active ingredients are continuously released in low concentrations
Enhanced Night Visibility: Comes with 3 light reflectors that easily clip on to the collar

One collar per animal to be fastened around the neck. Remove the collar from bag directly before use. Unroll collar and make sure that there no remnants from the plastic connectors inside the collar.
Insert end of the collar through the buckle. Adjust the collar around the animal's neck without tightening it too tight or leaving it too loose.
As a guide, it should be possible to only insert 2 fingers comfortably between the collar and the neck.
Pull excess collar thru the loop(s). Collar length of greater that 1 inch (2 cm) beyond the loop(s) should be cut off unless it is on a growing puppy, where some additional length may be needed for adjustment as the animal grows.
After application of the collar, three reflector clips may be fixed permanently to the collar to increase the animal's visibility in the dark. Take the clips out of the bag. The clips should be evenly distributed on the non-overlapping part of the collar. The clips are correctly applied when a clicking sound is heard. For safety reasons once the reflectors are fixed to the collar the clasp closes permanently and cannot be re-opened.

The collar should be worn continuously for the 8 month protection period. Check periodically and adjust fit if necessary, especially when puppies are rapidly growing. Rarely, mild application site reactions may occur, such as scratching, redmess and hairloss, which usually recover within 1-2 weeks without the need for collar removal.

In very rare cases, application site reactions, such as dermatitis, inflammation, eczema or lesions may occur. In these instances, immediately. If your animal is on medicaiton, consult your veterinarian before using this or any other product.This collar is designed with a release mechanism. In the unlikely event of a dog being trapped, the dog's own strength is sufficient to widen the collar to allow for quick release. Replace the collar after 8 months for optimal tick and flea protection.

The Bayer Polymer Matrix System ensures that both active ingredients are slowly and continuously released in low concentrations from the collar towards the animal.

Lifesaver of a collar!

I have been issuing these collars on my dogs for several years now....I cannot say enough good about them! I have two Belgian Tervurens (picture attached to this review) and with their extremely thick undercoat and long hair, finding fleas and ticks is nearly impossible! My first experience with a Seresto collar was on my one Terv, I put it on her and within 24hrs, there was a dead tick on the kitchen floor! From that moment on, they have to been without a Seresto collar!
Merchant Response:Great picture of some adorable dogs. Thanks for sharing.
Lasts eight months!
Best Flea and Tick Prevention
April 16, 2021
My boxer is 10 years old now and I want to keep her healthy and happy. I have used Seresto collars for years instead of chemical flea and tick products that would be applied and absorbed through her skin or ingested. She has never had an adverse reaction to the collar and I feel better knowing she’s protected because it works.

the company had what i needed. it shipped swiftly. would purchase from them again
these are legit
March 28, 2021
After reading that some of the flea collars are fakes, I decided to go here for my 3 dogs prevention needs. I checked for the Bayer symbol and number code, so these are real.
Merchant Response:Linda, all of our items are the real deal. Direct from the manufacture or through official veterinary distribution channels. Our products are the very same ones you would get from your vet clinic. Always, every time. This is our promise to you.
I used to use liquid flea and tick prevention. These collars are not messy and seem to work just fine. I have 3 big dogs and we walk and are outside many times a day.
One of my 3 dogs tends to sneeze for a while after a new collar is put on. This lasts for about a half hour after a new collar is put on. Other than that, all is good.
Product really works

Disappointed that the pills can't easily be broken with my fingers because they aren't oval shape. Pills are rectangular shape and have to be cut with a knife.

Got the collar in April after finding a tick on our eight year old Black Lab. have used topical products in the past, Millie does not like them, so on the advice of our vet tried Seresto. So Far So Good! No ticks in this awful tick season!
March 30, 2017
I used this product last year on my two dogs and it worked great. No more having to remember to apply Frontline or another flea and tick product every month. So easy

THE COLLAR IS GREAT AND LASTS FOR 8 MONTHS. It really works and is easy to deal with. I'VE USED OTHER PRODUCTS AND this one works the best for me.

Flea collar will be great if effective for the eight months advertised.
Excellent tick prevention
April 1, 2016
Excellent tick prevention. We used the Seresto collars last year for the first time, and had no serious tick bites on our dogs all season. Saves us from having to remember to apply monthly treatments, and one of our dogs got a bald spot from the Advantix solution.
Lasts 8 months
No medium size, so we buy large and cut them down.
