Provides 8-month protection from fleas and ticks.


The seresto™ Flea & Tick Collars for Large Dogs provide up to 8 months of continuous protection for your pet.


  • The non-greasy convenience of an easy-to-use, water-resistant collar
  • Sustained release technology ensures the active ingredients are slowly and continuously released over eight months
  • Kills fleas within 24 hours and continues to prevent infestations for eight months
  • Visibility reflectors included

Repels and Kills: Deer Ticks, American dog ticks, Brown Dog Ticks and Lone Star Ticks. If a tick is repelled or killed, it cannot attach to your pet and transmit organisms that cause diseases like Lyme disease, Rocky Mountain Spotted Fever and more. Treatment with seresto™ kills fleas and may reduce the risk of Dipylidium caninum tapeworm infection, as well as bartonellosis.

Water Resistant: The active ingredients in seresto™ collars are contained within the collar's matrix, making it water-resistant. Therefore, you do not have to remove the collar before your pet gets a bath or is submerged in water. In order to maintain 8 month duration, dogs must not be bathed more than once a month. For dogs that swim more than once a month, effectiveness is reduced to 5 months.

Large Dogs & Puppies: 27.5" and over collar length, over 7 weeks old and over 18 lbs.

Active Ingredients: Each active ingredient affects parasite nerve cells at different sites. When combined, the mode of action of Imidacloprid complements Flumethrin for a greater neurotoxic effect against parasites than with each active ingredient alone.

  • Imidacloprid (10% by weight) — effective against adult fleas and flea larvae (and lice on dogs)
  • Flumethrin (4.5% by weight) — effectively repels and kills ticks and kills larvae and nymphs. The collar's controlled-release system limits the amount of active ingredient available, lessening the chance of over-exposure.

Mode of Action: The make-up of the collar stores active ingredients throughout the collar and releases them through contact. These ingredients are transferred and distributed from the collar to hair and skin. Active ingredients move from areas of higher concentration to areas of lower concentration. As active ingredients wear off your pet over time, seresto™ replenished the hair and skin with a new supply of active ingredients providing continuous protection against fleas and ticks for 8 months.

Application: Remove the collar from the protective bag, unroll the collar and put on your pet. Make sure there is a minimum of two fingers of room between the collar and the animal's neck and remove excess collar. For additional visibility at night, simply attach the supplied reflector clips to the non-overlapping part of the collar. No activation is needed.

2-Step Safety Release System: In the unlikely event of a pet becoming trapped, your pet's own strength is sufficient to allow for quick release. A hard pull (on all collars) causes the ratchet release mechanism to allow a widening of the band. On the Small Dog and Cat collars, a harder pull triggers the breaking of the collar at the predetermined breaking point.
