Seresto Flea & Tick Collar for Dogs over 8kg

Notify Me When Available

Seresto Flea and Tick Collar for Dogs over 8kg provides 8 months continuous protection for dogs from fleas and 4 months from ticks in one easy application. Seresto collars also protects your dog against lice.

The active ingredients in Seresto collars are specially formulated for steady, dose-adjusted release that spreads over your dog, remaining in the fatty layer of the skin and coat, where they are effective against fleas and ticks all season long. Best of all, fleas don't have to bite your dog to be affected, so your pet suffers less of those painful flea bites. The collars also effectively repels and kills ticks, preventing them from attaching and feeding from your dog.

The top 5 benefits of Seresto Dog Collars:

  1. Fast relief from painful bites from fleas and ticks: * Protects your pet against fleas immediately after collar application * Protects your pet against ticks within 48 hours after application * Imidacloprid kills fleas on contact - they don't have to bite * Flumethrin ensures that ticks are repelled and killed
  2. Long-lasting and easy to use: * 8 months of continuous protection against fleas * 4 months continuous protection against ticks * No need to remember monthly dosing with spot on products * Simply unroll the collar, trim away the connector tabs, fit the collar so there is space for two fingers between the neck and the collar and trim away the excess
  3. Prevents development of further fleas: * Kills adult fleas in less than 2 hours after reinfesting * Kills 99%-100% of fleas before they lay eggs * Prevents infestation if your treated pet comes into contact with other pets with fleas * Helps clean up the flea population living in the house by killing larvae living in the pet's environment (bedding, floors and furniture)
  4. Safe for the family and the pet: * Predetermined break point and emergency release ratchet system to allow the collar to loosen or break without injury to your pet * Safety studies confirm a high Margins of Safety (MoS) for you, your pet, and the environment
  5. Water resistant: * Active ingredients stay locked in the collar and trapped in the fatty layer of the skin, so your dog can be bathed without needing to remove the collar, and with the peace of mind that it will still be effective against fleas and ticks.

Very sad

I had great success with flea control for many years but recently I have been devistated by the loss of my precious boy because I trusted the collar to control ticks. A tick grew to maturity within inches of the collar which had been renewed less than 4 weeks prior. Talking to a rep she said they can give a 98% guarantee only and daily searching is recomended which defeats the purpose of the collar for tick control.

Disappointed. New. Expensive.. ticks still. Getting on my dogs thanks. Adrian.


Works brilliantly. Long haired dogs. Love how long it lasts. Don't like using anything else.

Doesn't work

Dog has severe allergy to flea saliva, and Nexguard works but I hate using it because I have heard it makes dogs sick often. So I tried this collar, 2 weeks on and still scratching and biting himself. This happens evey year around this time and have been to the vets and it is fleas. Just one is enough to send him crazy. So collar is a very expensive and useless puppy decoration.

great product

Great service.
