Seresto Collar for Dogs

Seresto Collar for Dogs is a long-lasting treatment for your furry friend's protection from the most common external parasites, including fleas and ticks. It features a unique polymer matrix technology that allows the controlled release of the active ingredients, imidacloprid and flumethrin, over an extended period for continuous protection. This helps protect your dog from flea and tick infestations for 8 months.

This dog flea and tick collar kills and repels parasites through contact, eliminating the need for painful bites. This long-lasting collar is non-greasy, odorless and water-resistant. It remains effective even after a shampoo treatment, swimming or exposure to rain. Seresto is the #1 vet-recommended flea and tick collar according to Elanco USA and is trusted by dog parents.

Suitable For

Seresto Collar for dogs is suitable for puppies and dogs from 7 weeks of age.

Directions
How to Use Seresto Dog Collar

  • Just before use, remove the Seresto collar from the protective bag.
  • Unroll the collar and ensure no remnants from the plastic connectors are left inside the collar.
  • Insert the end of the collar through the buckle.
  • Adjust the collar around your dog's neck.
  • To ensure the collar is not too tight or too loose, leave a gap of two fingers between the collar and the dog's neck.
  • Pull the excess part of the collar through the loop(s). Cut the excess length, leaving about 1 inch (2 cm) beyond the loops.
  • Do not cut the excess length when using it on a growing puppy.
  • Check the collar periodically and adjust if needed.
  • Make your dog wear the collar continuously for uninterrupted protection and replace it with a new collar every 8 months.
  • It is designed with a release mechanism. Though unlikely, if your dog is trapped, the dog's own strength is sufficient to widen and quickly release the collar.

Seresto Dog Collar FAQ

How does the Seresto Collar for dogs work?

Seresto tick prevention collar contains imidacloprid and flumethrin. It uses a patented polymer matrix that spreads from the site of direct contact over your dog's skin surface. This sustained release technology allows slow release of the formula from within the collar, spreading from head to toe, including the tail. The new supply of active ingredients is continuously replenished in low concentrations for 8 months. Imidacloprid protects from fleas, while flumethrin targets ticks.

How effective is the Seresto Collar for dogs?

According to the product label, this best flea collar for dogs kills existing fleas on dogs 24 hours after the first application. After 24 hours, it kills new fleas on the dog within two hours and protects against further flea infestations for 8 months. Seresto flea & tick collar starts preventing new tick infestations at 48 hours post-application. After 48 hours, it repels and/or kills any new ticks on the dog within 6 hours.

Do I need to remove the Seresto collar before bathing my dog?

This water-resistant dog flea collar stays effective even after swimming, exposure to rain or a shampoo treatment. Do not bathe your dog more than once per month and use a gentle, soap-free shampoo to maintain its 8-month efficacy.

How do I remove the Seresto collar from my dog?

To remove the Seresto Collar from the dog, squeeze the outer sides of the buckle while pulling from the other end or side of the collar. You may also cut the collar before applying a new one.

Is the Seresto collar safe for dogs?

Yes. This 8-month flea and tick protection is safe for use on puppies from seven weeks of age. Consult a vet before using it on aged, debilitated, pregnant, breeding, or nursing dogs. To prevent drug interactions, talk to a vet before using it concurrently with other veterinary treatments.

Great Price! Mar 09, 2025
One of the very few items I've ordered in the past that the price hasn't jump up sky high. I actually got this one for little under a dollar less than I paid in 2024. Hope the price stays lower than competitors.
