Seresto Collar for Large Dogs

Make your dog’s protection against parasites simple with the Seresto Collar for Large Dogs. It is one of the most vet-recommended flea and tick collars for dogs. This non-greasy, odorless collar offers long-lasting protection and kills and repels fleas and ticks for 8 continuous months. It provides 3-way protection against fleas, ticks, and lice without irritating your pet.The collar features a unique release mechanism for added safety. In an unlikely situation where your dog becomes trapped, your dog’s own strength is usually sufficient to widen the collar for quick release. It is water-resistant and remains effective after shampooing, swimming, or exposure to rain or sunlight. Suitable for dogs and puppies from 7 weeks of age, weighing over 18 lbs.

Seresto Collar for Large Dogs Coverage

Seresto Collar is a convenient, no-mess, wearable flea and tick treatment option, especially for fussy eaters:

  • Kills and repels fleas before they lay eggs, including fleas that may cause Flea Allergy Dermatitis (FAD) or Flea Bite Hypersensitivity (FBH).
  • Repels and kills fleas that may transmit canine vector-borne diseases such as tapeworm infections, bartonellosis, and rickettsiosis.
  • Repels and kills ticks for 8 months, including deer ticks, American dog ticks, brown dog ticks, and lone star ticks.
  • Repels and kills ticks that may transmit Lyme disease, anaplasmosis, Rocky Mountain spotted fever, ehrlichiosis, bartonellosis, babesiosis, and canine hemoplasmosis.
  • Kills chewing lice.

How Does the Seresto Collar for Large Dogs Work?

Seresto Collar contains two active ingredients: flumethrin and imidacloprid. Imidacloprid controls flea infestations, while flumethrin kills and repels ticks. These ingredients spread across your dog’s skin surface through direct contact, covering the entire body from head to tail.The polymer matrix technology ensures that the active ingredients are released slowly and continuously, providing up to 8 months of uninterrupted protection.

The collar works through contact, meaning fleas and ticks do not need to bite your dog to be killed. After 24 hours of application, new fleas are killed within 2 hours. After 48 hours, new ticks are repelled and/or killed within as little as 6 hours.

Directions for Use

Instructions To Use Seresto Collar

  • Weigh your dog and select the suitable Seresto Collar size.
  • Remove the collar from the protective bag directly before use.
  • Unroll the collar and ensure there are no remnants from the plastic connectors inside it.
  • Insert the end of the collar through the buckle.
  • Adjust the collar around your dog’s neck. Do not make it too tight or too loose. As a guide, fit two fingers comfortably between the collar and your dog’s neck.
  • Pull the excess collar through the loop(s).
  • Cut the collar to a length no greater than 1 inch (2 cm) beyond the loop(s), unless using it on a growing puppy. Additional length may be needed for adjustment as your puppy grows.
  • Check the collar periodically and adjust the fit if required, especially during rapid growth stages.
  • The collar should be worn continuously for the 8-month protection period. There is no need to remove it while bathing. However, to maintain the full 8-month duration, do not bathe your dog more than once per month.
  • Replace the collar after 8 months for optimal flea and tick protection.
