Seresto Small Dog Vet-Recommended Flea & Tick Treatment & Prevention Collar for Dogs Under 18 lbs | 8 Months Protection

Inside the unique polymer matrix of Seresto are two active ingredients:

• Imidacloprid has been used in products for years to control flea infestations.
• Flumethrin effectively repels and kills ticks.Flumethrin works together with imidacloprid to provide dual action against fleas and ticks. No other treatment has this combination of ingredients.The active ingredients spread from the site of direct contact over the skin surface of the cat or dog.*Sustained release technology*Seresto works similarly to a monthly topical, but as the active ingredients wear off over time, a new supply is continuously replenished in low concentrations. The active ingredients spread from the site of direct contact over the skin surface.Bayer's polymer matrix technology is designed to slowly and continuously release the active ingredients for eight months, a duration that makes it clearly different from other flea and tick collars.

Seresto is water resistant. The active ingredients of Seresto are contained within the Bayer Polymer Matrix, making it water-resistant. Therefore it is unnecessary to remove the collar before the pet is immersed in water. Seresto remains effective following a shampoo treatment, swimming, or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for eight months. In order to maintain an 8-month duration, dogs must not be bathed more than once per month. For dogs that swim once a month or more, the control duration is reduced to five months for fleas and seven months for ticks.

Because some pet owners may be concerned that a cat or small dog could get stuck while wearing a collar, Seresto is designed with a safety release mechanism. In the unlikely event of the cat being trapped, the cat's own strength is sufficient to widen the collar to allow for quick release.A hard pull causes the ratchet-release mechanism to allow a widening of the collar.The small dog and cat collars are equipped with a predetermined breaking point. A harder pull triggers the breaking of the collar at this point.

There is no expiration date required on the packaging by the EPA for this product. The product should be kept in its original packaging and stored as directed on the label.
