How to apply the Seresto collar on your dog: 1. Remove the collar from its packaging. 2. Unroll the collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain. 3. Insert the end of the collar through the buckle and loops. 4. Adjust the collar around your dog's neck until it fits comfortably on them.5. Two fingers should fit beneath the collar and neck to ensure it's not too tight. Any excess length of the collar beyond an inch past the loops should be cut off, unless it is on a growing puppy, where some additional length may be needed for adjustment as the puppy grows. 6. Check periodically and adjust fit if necessary, especially on growing puppies.

Customers say

Customers overwhelmingly praise this flea and tick collar for delivering consistent, long-lasting protection over eight months. Most report complete elimination of parasites, with many noting zero sightings of live fleas or ticks since application, even in high-exposure areas. Long-term users spanning years or decades rely on it exclusively, often citing veterinarian recommendations. The collar is gentle on sensitive skin, requires no reapplication, and eliminates monthly treatment hassles. A small group reports ineffectiveness or ongoing scratching, though these experiences represent a minor fraction of feedback. Overall, reviewers consider it the most effective solution they've tried.

[This review was collected as part of a promotion.] Giving this 5 stars because I’ve heard great things and read great reviews- my dog was recently in the ER for a bacterial infection and has been heavily medicated so was weary on adding anything into his system too (even externally). But it definitely seems easy to use and doesn’t at all seem too tight or uncomfortable.

[This review was collected as part of a promotion.] This collar fits my German Shepherd perfectly. It can adjust the size and it’s soft. It has no strong odor. I like using this collar when I take my dog out.

Product was well packaged. Have used this for my Cane Corso for the last two years and has worked extremely well. You can cut it to size so it fits properly and you do not have excess hanging off the collar. We live in a wooded area and I have never seen a single tick or flea on her since we began using this product.

The only flea and tick protection I’ve ever used for my dogs. The collar is easily adjustable to your dogs neck and no irritation noted. Works effectively and I’ve never had issues with fleas or ticks since using this product. Highly recommended!

We’ve had our little girl on this flea killer for 10 years now. She has never been bothered by those little parasitic vampires ever since. She wears it under her collar comfortably. It adjusts to fit her, just snip off the excess. Never had any skin irritation.

The collar is smooth. And adorable it last when my husky scratch his neck. It works really good with all that hair. I just still didn’t have to worry about fleas. The instructions are very easy to follow. I had no problem fitting it to my dog and cutting out the rest.

This flea collar held up really well for our large dog. We usually switch them out around the 6 month mark but they have done great for keeping bugs off of him! Easy to get on, easy to understand instructions.

Questions

1 - 10 of 178 Questions

are your seresto collars the genuine thing ? athey generic

  1. Yes, these are genuine



I'm debating switching from Frontline to this flea collar, but my dog is epileptic I want to make sure that this collar is safe to give to her. I looked it up, but I'm getting conflicting results on whether or not this collar is safe for epileptic dogs.

    Can you use Seresto collar if you are giving your dog Next Guard?  If so if your dog is 45-46 lbs but is 9 months old what size do I need to get?  Or should I change the kind of flea and tick I give?

      what is considered the weight limit for a small dog, for this collar, I am not sure what size to get. Your website says small or large dog, no medium size?

      1. If you look at the picture, it says the weight on the front of the packaging. Small dog is under 18 lbs, large dog is above 18 lbs.



      Who's Elanco? What happened to Bayer as the manufacturer? Are they still good?

      1. Bayer got out of this business and sold their animal health lines to Elanco, which in turn was spun off from Eli Lilly, who wanted to concentrate on more profitable human pharma. It's a major player even if its only a few years old.



      Can these collars be put on immediately following a bath with hair/fur still damp?

        Is it ok if you dog sleeps in the bed with your while wearing this collar? I am just curious if the chemicals on the collar are safe for prolonged human contact. Is it ok to take the collar off at night?

        1. I purchase these from a competitor and they were the fake collars and we were all itchy!! I got a full refund and purchased from a vet. No itiching or skin issues at all. I think RIM1949 got a fake set of collars. Easiest way to tell is the case is embossed, and there is more details on the back. You can find more details on a google search.



        What are the letter and numbers on the inside of the colar.

          Can this product be used on an as needed basis (meaning - only put it on them when you are going hiking for instance)? Or do they have to wear it all the time no matter what?

          1. I believe that the seresto collar would be most effective if worn all the time. Ticks can be in our backyards. I have collars on my indoor cats because my dog could unknowingly bring in a tick 



          What size collar do I need to purchase for my dog that is 29 pounds the small or large collar?
