Indications for use

Seresto for Dogs:

  • Repels and kills ticks for 8 months, including:

    • Deer ticks (vector of Lyme disease and anaplasmosis), American dog ticks (vector of Rocky Mountain spotted fever and ehrlichiosis), Brown dog ticks (vector of ehrlichiosis, anaplasmosis, bartonellosis, canine hemoplasmosis, babesiosis, and Rocky Mountain spotted fever), and Lone Star ticks (vector of ehrlichiosis).
  • Prevents tick infestations within 48 hours after application.

  • Re-infesting ticks are repelled and/or killed as quickly as 6 hours.

  • Quickly kills fleas on dogs within 24 hours and continues to prevent infestations for 8 months.

  • Treatment with Seresto kills fleas and may reduce the risk of tapeworm infections (Dipylidium caninum), bartonellosis (Bartonella vinsonii, Bartonella spp.), and rickettsiosis (Rickettsia felis), which are types of canine vector borne diseases).

  • Re-infesting fleas are killed within 2 hours with protection against further flea infestation lasting 8 months.

  • Kills fleas before they lay eggs.

  • Seresto aids in the control of flea larvae in the dog’s surroundings following contact with a Seresto-treated dog.

  • Kills chewing lice for one month.

  • Aids in the treatment and control of Sarcoptic mange.

  • No need to remove collar when your pet goes swimming or gets bathed.

  • Bayer Polymer Matrix ensures that both active ingredients are slowly and continuously released in low concentrations.

  • Make sure to replace the collar after 8 months for year-round pest prevention.

  • Light reflectors for added visibility in the evening and at night.

Administration and dosage

  • One collar per animal to be fastened around the neck.

  • Remove collar from protective bag directly before use. Unroll collar and make sure that there are no remnants from the plastic connectors inside the collar.

  • Insert end of the collar through the buckle. Adjust the collar around the animal’s neck without tightening it too tight (as a guide, it should be possible to insert 2 fingers between the collar and the neck).

  • Pull excess collar through the loop(s) and cut off any excess length extending 1 inch (2 cm) beyond the loop(s).

  • After application of the collar, three reflector clips may be fixed permanently to the collar to increase the animal’s visibility in the dark.

  • Take the clips out of the bag. The clips should be evenly distributed on the non-overlapping part of the collar.

  • The clips are correctly applied when a clicking sound is heard. For safety reasons once the reflectors are fixed to the collar the clasp closes permanently and cannot be re-opened.

  • The collar should be worn continuously for the 8 month protection period. Check periodically and adjust fit if necessary, especially when puppies are rapidly growing.

  • This collar is designed with a safety-closure mechanism. In the unlikely event of a dog being trapped, the dog’s own strength is sufficient to widen the collar to allow for quick release.

  • Replace the collar after 8 months for optimal tick and flea protection.
