Seresto™ Flea & Tick Collar for Large Dog

The Seresto collar for dogs repels and kills ticks and kills fleas through simple contact, which means they don't have to bite your dog before they fall off and die. No biting means no itching and giving your dog the needed protection. If the parasites aren’t biting and sucking blood, there is a reduced risk of transmitting infections, which means you can put Seresto on and simply know that your dog is well protected. Seresto is a collar like no other! It works by releasing its active ingredients in controlled, low doses, allowing your dog to stay protected for up to eight months at a time. Odorless, water-resistant and effective against both fleas and ticks, the Seresto dog collar is the simple, easy way to keep your best friend protected for longer.

Lead the pack with long-lasting protection

Seresto® is a convenient, easy-to-use, non-greasy, odorless collar that kills and repels fleas and ticks for 8 continuous months.

Seresto® is veterinarian-recommended and available without a prescription.

No biting required

Unlike oral flea and tick products like tablets or chewables, Seresto® does not require fleas and ticks to bite your dog in order for them to die.

Less hassle, no mess

The 8-month Seresto® collar is non-greasy and odorless, plus you don’t have to remember to apply monthly treatments. It doesn’t interfere with other leash collars, so your dog can easily wear them simultaneously.

From bath time to play time

Is your dog a champion swimmer? A sprinkler chaser? A bath time enthusiast? Seresto® is water resistant. You can leave your Seresto® collar on for swimming, even a monthly bath.

Swimming or bathing more frequently than 1x per month will reduce duration of effectiveness. See product label.

Is Seresto® the right choice for your dog?

Outside dog? Choose Seresto®. Inside dog? Choose Seresto®. Worried about fleas AND ticks? Choose Seresto®.

And if you dislike the inconvenience of applying monthly topicals, choose Seresto®. After all, applying just one 8-month collar is more convenient than having to give a monthly topical for 8 consecutive months.

For dog owners that don't like to take pills – and owners who don’t like to administer them – Seresto® takes moments to apply and provides 8 continuous months of effective flea and tick protection. And unlike monthly chewable products, Seresto® does not require a prescription and kills fleas and ticks through contact, so they don’t have to bite your pet to die.
