  • The collar should be snug enough that you can insert 2 fingers without discomfort beneath the collar.
  • To keep the seresto dog collar in place, pinch the excess of the collar and pull it through any extra slots on the buckle. If your pup’s flea collar length exceeds 1 inch (2cm) beyond the slot, then you will need to cut it off. However, this may be necessary if it is a puppy that is growing. Just make sure never to cut off any excess seresto flea collar when doing so in order not to hamper the pup’s growth.
  • When the reflector clips are applied, the clasp automatically closes permanently and cannot be re-opened. Remove the reflector clips from their bag and distribute them evenly on the top section of the seresto collar. Make sure that there is no overlap on the collar before fixing them into place by pressing down firmly for a moment. Once you hear a clicking sound, release your pressure and enjoy your increased visibility at night!

  1. Kay

    Easy to use, doesn’t have a weird smell my dogs dont seem to mind it and most importantly it WORKS! Very rarely do I even see a tick or two on them.

  2. Joy L

    I’ve had Seresto collars on both of our dogs and cats for years with no issues, and have never had an issue with fleas or ticks. Several times a summer we will find dead ticks on our dog, indicating that they seem to be doing their job.

  3. Sonata 88

    I’m so happy with Seresto collars because I’ve had dogs of all shapes and sizes, for years. I like knowing that my dogs are safe. You may think they’re a bit pricey, but there’s really no comparison, when you look at their value vs. the cost of prevention month-to-month. And it’s much cheaper than other options in stores. Since I found out Seresto works, I haven’t seen a single flea or tick on any of my dog.

  4. Billy

    I always use Seresto collars for my golden retriever. Works great. Put on new seresto collars every 7 to 8 months.

  5. Vinca

    I was so excited to try out the Seresto flea collar for my dog. I had heard great things about it and was eager to see if it would be as effective as said to be. I was not disappointed! The collar worked like a charm and my dog was flea-free in no time. I am so happy with the results and would recommend this product to anyone looking for an effective flea collar for their dog.

    Seresto flea collar for dogs is so effective that I decided to try it on my cat. I was amazed at how well it worked! My cat didn’t have a single flea on her after I put the collar on.

  7. Manda

    The truth is that having your dog suffer from fleas and ticks is just about the worst thing that can happen to them. Not only are the bites uncomfortable for them, but the parasites can also carry serious diseases that might make your pet very sick as well. This is why it is so important to start using a safe and effective flea collar as soon as possible.

    The seresto collar has helped the family’s dog to stop itching. She started developing scabs, but now they are starting to go away slowly.
