Seresto^®

The Seresto^® collar works with a unique polymer matrix of two active ingredients, which spread from the site of direct contact over the skin surface of your dog:

• Imidacloprid has been used in products for years to control flea infestations.
• Flumethrin effectively kills and repels ticks.
• Flumethrin works together with imidacloprid to provide dual action against fleas and ticks. No other product has this combination of ingredients.

Sustained release technology

Seresto^® works similarly to a monthly topical in the fact that the active ingredients spread from the site of direct contact over the skin surface. The active ingredients in Seresto^® are released in low concentrations from within the collar and, thanks to your pet's skin and coat, spread from head to toes, even the tail. As the active ingredients wear off over time, a new supply is continuously replenished in low concentrations for 8 months. The long-lasting, 8-month duration of Seresto^® differentiates it from other flea and tick collars.

All Seresto^® collars are designed with a ratchet release system. The Seresto^® small dog collars also have a pre-determined breaking point in the collar. This is the zig zag area on the collar.

How to apply the Seresto^® collar on your dog:

1. Remove the collar from its packaging.
2. Unroll the collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain.
3. Insert the end of the collar through the buckle and loops.
4. Adjust the collar around your dog's neck until it fits comfortably on them.
5. Two fingers should fit beneath the collar and neck to ensure it's not too tight. Any excess length of the collar beyond an inch past the loops should be cut off, unless it is on a growing puppy, where some additional length may be needed for adjustment as the puppy grows.
6. Check periodically and adjust fit if necessary, especially on growing puppies.
7. Seresto^® comes with three optional reflector clips that can be attached to the collar to help keep your dog visible at night. The reflector clips should be evenly distributed on the non-overlapping part of the collar.

How to take the Seresto^® collar off your dog:

Squeeze the outer sides of the buckle while pulling from the other end or side of the collar. Some may find it just as easy to cut the collar off before applying the new Seresto^® collar.

Seresto^® kills existing fleas on dogs within 24 hours after application. Once Seresto^® has been on your dog for 24 hours, re-infesting fleas are killed within two hours. Infestation prevention with new ticks starts within 48 hours after Seresto^® collar application. Re-infesting ticks are repelled and/or killed in as quickly as 6 hours.

Seresto^® works to kill and repel fleas and ticks for 8 continuous months. That’s a big deal because a bite from a flea or tick can be painful and can transmit deadly diseases.
