Product Summary:

Seresto Flea & Tick Collar for Small 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 small dogs and features a 15-inch, easy-to-use, no-hassle, waterproof collar size. It can be used by puppies seven weeks and older, weighing up to 18 lb. 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:
Because some pet parents may be concerned that a small dog could get stuck while wearing the Seresto® Flea & Tick Collar, it is designed with a safety release mechanism, where in the unlikely event your 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.

David T on May 31, 2015
They work great for my dog. I've used them 3 times now and have never seen any fleas or ticks on my little girl. They are economical and last up to 8 months. Just remember to take the collar off when you bathe or groom them and they do last for the total 8 months.

It works. Advantage, Revolutions and Front-line did not protect the dog like this collar does against fleas and ticks.
Katheryn D on Oct 7, 2014
My dog is allergic to the topical flea treatments (Advantix, etc.) and, after reading the positive reviews about the product and downloading a $20.00 rebate from the manufacturer, I figured I'd try it.

We love this product for our Maltese and terrier mix. This will be our third time buying this product. We had flea infestation on our dogs with the spot treatment and live in Florida where Fleas are an annual problem.
I love that you can bathe and groom the dogs and never remove the collar.

Is there a difference in dosage between the small and large collars?
We have a 19 lb Miniature Schnauzer and we got a large collar by mistake. It's bulkier than the small that he wore last time.
Will the dosage be too high for him?
Bernadette M on Apr 9, 2017
BEST ANSWER: It is not recommended to use the large collar on a small dog as it does contain extra dosage which would harm the dog.
Does the collar expire if you don't use it for many months but want to buy it when it is on sale?
A shopper on Oct 4, 2014
BEST ANSWER: I contacted support via phone and product begins its lifespan when seal is removed and is exposed to air so u can save it by keeping sealed
I have a 17 lb jack russ El who wears a 16 inch collar. Would you squeeze a small on or go to large?
A shopper on Jan 28, 2016
BEST ANSWER: A small would probably be ok.
what size should I order? I have 2 shelties that weigh around 20-25 lbs.
Jacki W on May 26, 2015
BEST ANSWER: Hello! The large Seresto collar is recommended for dogs over 18lbs and older than 7 weeks. Below I have copied the link to the item page.
when flea season is over can you save the collar for future use by sealing it in an airtight bag?
Mary M on Nov 15, 2016
BEST ANSWER: I believe this is actually a question for the manufacturer. Since I live in Indiana in the summer months and Florida in the winter months, my dog wears the Seresto collar year round - replacing it every 6-7 months (depending on how much she swims and gets a bath during the 8-month period). Our home in Indiana is on a lake and backs up to a State Park. Since she's been wearing this collar (approx. 3 years), she has not had a tick or flea on her. Love the collar.
What if my dog is 18 lbs? Which size should I get?
A shopper on Apr 28, 2017

Pamela C on Mar 29, 2015
BEST ANSWER: Hello! the small collar is 15" and the large is 27 1/2".
I have a 2.5lb 6 month old Yorkie. Is it safe for him? Was told his hair might fall out
A shopper on Apr 27, 2017
BEST ANSWER: Never heard that before I guess it's possible? I have the same breed and started him on the seresto between 6 and 10 months. He was lass that 3 lbs also. It's taking him almost 3 years to get to 7.6 lbs lol But he just did not do well on the drops, made him sick to his stomach. The Seresto did super well! No rash, no hair loss. I do keep the neck fur trimmed, not to the skin though, so it can touch the neck better. I've never had a flea on him nor tick and we are in Ohio. Best of luck with your little one. 🙋🏻♥️
I have two dogs and worry about them licking each others collars. Would they get sick from it? My question
has to do with the Seresto flea and tick collar.
A shopper on May 14, 2015
BEST ANSWER: I love this collar! It works really well; there have been no ticks or fleas on my dog who normally gets at least 5 or 6 with each outing in the woods. I really don't think your dogs will get sick from licking the collar. I've accidently kissed my dog's flea/tick collar with no adverse effects (a few times)...The collar doesn't have any residue or smell, so unless your dogs are attracted to flea collars, I don't think a few licks will do any harm. I have 3 dogs and have not had any problems with poisoning. By the way, I used to use Frontline Plus, and have found this collar to be more effective, both in cost and use.
does the collars keep the whole body free of ticks?
A shopper on Sep 4, 2018
BEST ANSWER: Knock on wood, we are on our 3rd Seresto collar for our Cairn terrier and our mixed breed who weighs about 28 lbs. Both dogs flea and tick free, and we live in FL! Love this collar!
I got a tea cup chiaua she is 3lbs is the small dog collar safe to put in her?
Jessica B on Aug 29, 2017
BEST ANSWER: yes it is. I would say to leave it a little loose..... to let it rest low low on her neck. They make a collar for small Dogs & Puppies, for dogs 7 weeks of age & older and up to 18 lbs. I have a 7lb dog and the pills and drops and chews made him sick as a puppy. So we really just kept him inside and bathed him monthly until he got a little older and still everything made him ill. Then I think he was about a year and a half when seresto came out and he has had no side effects. 😁 Hope this helps.
XHhave a 2 1/2 pound Yorkey is it safe for him was told his hair might fall out?
A shopper on Apr 27, 2017

Per the product label:

Slight hair loss and mild skin reactions due to the mechanical irritation of the collar may occur
at the application site which usually recover within 1 or 2 weeks without the need for collar removal.
