Give your dog long-lasting protection against fleas and ticks with a Seresto Large Dog flea and tick collar. Unlike other flea and tick protection, Seresto Large Dog flea and tick collars kill and repel fleas and ticks for eight continuous months. Seresto Large Dog flea and tick collars are recommended by veterinarians, stocked by 8,000 vet clinics* and have been trusted* by pet owners for nearly a decade. Seresto Large Dog collars make your dog’s comfort a priority by killing fleas and ticks on contact, so pests don’t have to bite your dog to die. Existing fleas die within 24 hours after initial application of the collar. After 24 hours, any new fleas on the dog are killed within 2 hours with protection against further flea infestation lasting 8 months. The prevention of infestations with new ticks starts at 48 hours after application of the collar. 48 hours after application, any new ticks are repelled and/or killed in as quickly as 6 hours. Seresto Large Dog collars protect against common pests like deer ticks, American dog ticks, brown dog ticks, and Lone Star ticks; they’re also effective against chewing lice. Fleas and ticks not only cause discomfort; fleas can transmit bartonellosis or tapeworm. Ticks can transmit Borrelia burgdorferi which causes Lyme Disease. Check the product label for information on potential side effects. Seresto Large Dog flea and tick collars are for dogs at least 7 weeks old, and there’s no prescription needed. They’re odorless, non-greasy and water resistant to swimming, exposure to rain or sunlight, bathing, and shampoo treatment.** Seresto is a trademark of Elanco or its affiliates. *Elanco Animal Health, data on file **Seresto Large Dog is water resistant and remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for 8 months. In order to maintain an eight-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 5 months for flea control and reduced to 7 months for tick control.
Directions for Use
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.

Very effective flea collar
4 days ago
[This review was collected as part of a promotion.] Protect your fur babies from biting fleas and infestations. This flea color was easy to apply to my energetic frenchie and did not irritate his skin at all. Ive never been a fan of the smell from this product, but I can only assume the smell helps with the effectiveness of the product. My active boy was unbothered by the collar and the collar seemed to be effective since I have yet to find any creepy crawlers. I will continue to use this product as a preventative

Great Product

[This review was collected as part of a promotion.] We love the convenience of these collars. To be able to put them on and forget about the for most of the year is great. They work well to keep the fleas and ticks off the dogs too, especially during camping season in the woods. If I had any complaints about these collars though, I would say that, despite not cutting any length off of ours, the end seems to wiggle free of the loops every so often and require adjustments.

[This review was collected as part of a promotion.] So this season has been full of ticks. We put this collar on our dog Rory it doesn’t bother her and we haven’t found a tick yet. We run around in the woods quite a bit too.

This flea collar offers reliable protection, effectively repelling and killing fleas for months. Safety is a priority, with non-toxic ingredients suitable for most dogs. It comes in adjustable sizes, ensuring a comfortable fit. The collar’s durability holds up well against daily wear, including water exposure. While it provides great value compared to frequent topical treatments, results may vary by dog and flea severity. Overall, it’s a convenient, long-lasting solution for flea prevention with minimal hassle.
