Product Summary:

Seresto Flea & Tick Collar for Large Dogs
The performance you expect from a topical flea and tick treatment, in a non-messy, easy-to-use collar

The Seresto® Flea & Tick Collar for Small Dogs is an easy-to-use, effective way to kill and repel fleas and ticks. The innovative Sustained Release Technology offers odorless and non-greasy protection for up to eight months. It begins to kill fleas within 24 hours and ticks within 48 hours of initial application.

The Seresto® Flea & Tick Collar is for large dogs and features a 27½-inch, easy-to-use, no-hassle, waterproof collar size. It can be used by puppies seven weeks and older. It kills deer ticks, American ticks, brown ticks, and Lone Star ticks, as well as chewing lice. The dual action protection provides a continuous release of two active ingredients: Imidacloprid controls flea infestations, while Flumethrin effectively repels and kills ticks. The combination works like a monthly topical flea and tick treatment, yet is designed to slowly release the ingredients in low concentrations for eight months.

Item Specifications:

Special Safety Feature:
The collar is designed with a safety release mechanism, where in the unlikely event the dog is trapped, its own strength is sufficient to widen the collar and offer a quick release. Because the collar is equipped with a predetermined breaking point, a hard pull triggers the breaking of the collar at this point.

Directions for Use:
To ensure the easy to use waterproof collar is applied correctly, read the complete directions for use found in the package insert.

  • Once you are ready to fit the collar to your dog, remove from protective bag immediately prior to use.
  • Unroll collar remove the plastic connectors inside the collar, ensuring that no remnants remain.
  • Insert end of the collar through the buckle.
  • Adjust the collar around the dog’s neck without tightening it too tight (as a guide, two fingers should fit between the collar and the neck).
  • Pull excess collar through the loop(s) and cut off any excess length extending one inch beyond the loop(s).
  • 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.

DEBORAH C on Apr 6, 2019
I live in a high tick area and these collars work.
Martha S on Apr 5, 2019
I have used this collar on both my greyhounds and have been very satisfied with the product. I may find a sick or dead flea on the dog within the first week of putting on the collar, but thereafter nothing! Neither dog had any problems with wearing the collar
DEBRA W on Mar 18, 2019
I use the Seresto Flea and Tick Collar because it is the only flea and tick product that my Labrador hasn't had a reaction to.
KAREN H on Mar 4, 2019
Works great! Even with our dogs that swim
LINDA G on Feb 22, 2019
Excellent product - If you have multiple dogs in the household they will sometimes try to chew the collars. I had one ingest it and other than a very mild stomach upset he was fine. I am now very careful when my dogs are all together.
VALERIE B on Feb 14, 2019
Vet recommended and does the trick whether up north or in he southern states..
SUZANNE W on Nov 23, 2018
Serestos reputation for long lasting protection and a recommendation from a friend led me to begin using Seresto collars here in 2018. These new collars are for Spring 2019
sheila p on Nov 16, 2018
Works great for Roger our 23# Sheltie. He has a 500 Land Preserve for a back-yard. And yes he does occasionally get ticks and he tests positive but its a help.
ROBERT C on Oct 16, 2018
It lasts a long time and you don't have to keep giving them doses of other flea medicine on their skin.
Jeanette F on Sep 26, 2018
Excellent product.
MARGARET P K on Sep 18, 2018
This has been the only flea/tick preventative that worked for my dogs.. When live in an area where you can't see the forest through all the trees this collar is a life saver.. It keeps my dogs flea free and have not had any tick issues either. Love, Love this product!!
KATHLEEN M on Aug 22, 2018
Haven't found any ticks or fleas since we started using these (in October 2017). We are in the heart of deer tick country (central MN) and usually have pulled off many ticks by this time of year. We haven't found any this year (July 2018). We remain vigilant; we are Very thankful!
Martha H on Jul 16, 2018
I have used them before and like the result. This is also a good price for them.

FRANCIS W on Mar 20, 2018

I have been using these collars on my cats and dogs for 8 months and they have had no fleas and ticks the whole time and they always have had them with other methods of getting rid of fleas and ticks
Kathleen W on Mar 7, 2018
I've been using this collar for my dogs for several years and it works! After putting it on, I may see some sick or dead ticks on him, but after about a week, I never see healthy ticks again and no fleas whatsoever. My dog is a greyhound, but I've never seen any signs of skin irritation. Highly recommended!!
DEBRA W on Mar 7, 2018
See comments in cat section.
NANCY F on Mar 2, 2018
My dog has used this for the past 3 years and it really works for ticks. There was no skin irritation or other problems.
judith c on Feb 24, 2018
they work!
Diane S on Feb 24, 2018
Seresto collars seem to be the most effective with the fewest side effects, if you must use a flea/tick preventative.
I used a number of natural remedies for the past 15 years, but we had a major flea infestation last summer and as usual, there were a few black legged (deer) ticks I found on the dogs. Since switching to this collar, we have had no ticks and obviously, no fleas.
The other reason is Seresto collars have acted as a deterrent. No ticks on our dogs at all. That's a first for us.
Martha H on Feb 23, 2018
Great items! Don't have to worry about applying monthly. My dogs are bathed and swim and still works
theresa c on Feb 22, 2018
I have a dog who is sensitive to topical flea preparations. We tried this and she tolerates it well and we don't have fleas or ticks. She also swims a lot and it keeps working.
Virginia H on Feb 10, 2018
Only flea and tick prevention that my sons GSD can use. Going to try it on my GSD as the oral choices don't seem to work more than a few weeks for her.l
SHARON H on Jan 25, 2018
it works the best on my dog for flea and tick protection
judith c on Jan 22, 2018
I have been using Seresto collars on my dogs and cats for several years and they work very well. Surprisingly, my cats do not mind them.
SANDRA U on Jan 10, 2018
Works good for dogs with thick coats
NANCY C on Dec 15, 2017
It actually works and does provide flea protection for the eight months claimed. I was amazed, as this is not normally the case here in Florida. Our fleas have become resistant, because of warm Winter months. I have an 80 lb. white Boxer who is sensitive to many products and I was skeptical she would tolerate a long term flea collar. I initially contacted Bayer about safety and effectiveness, as my usual choice of Advantage II was not working. Very pleased with the Seresto collar.
Susan G on Dec 6, 2017
I used this product this year and saw no fleas or ticks on my dog. There appeared to be no side effects, and it worked after my dog got wet.
ANNE E on Dec 3, 2017
Because it's the best you can buy, and you don't have to worry about drops every month.
connie S on Apr 9, 2019

DEBORAH C on Apr 6, 2019
I have a dog 21 lbs is that consider large?
Linda D on Sep 18, 2017
BEST ANSWER: Yes, the small size is up to 18 pounds. Any dog over that weight would need the large.
I have a 17lb dog, which colar is best?
A shopper on Mar 13, 2018
BEST ANSWER: Not the large, I use it on my 130 lb St Bernard. Probably the small if they make one or the medium and cut part of it off.
Do you get Seresto collars directly from Bayer?
Marna M on Apr 12, 2019
BEST ANSWER: Bayer is the manufacturer of the product.
Why did you raise the price to $72.99 before you reduced 25% off? No where online or in stores is it sold for$72.99.
Judy W on Apr 25, 2018
BEST ANSWER: Item original price is $72.99 the manufacture of this item is allowing a discount so item reflects $52.99. This item is not eligible for 25% off.
do you send the 2019 collar?
