  • Long-lasting flea and tick collar kills and repels fleas for 8 continuous months
  • Seresto is the #1 veterinarian recommended flea and tick collar* *Elanco Animal Health, data on file

Description

Give your dog long-lasting protection against fleas and ticks with the number-one vet-recommended flea and tick collar*. Unlike other flea and tick protection, Seresto large dog collars kill and repel fleas and ticks for 8 continuous months.

Seresto collars make your dog’s comfort a priority by killing fleas and ticks through contact, so pests don't have to bite your dog to die. Existing fleas die after 24 hours of 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 for 8 months.

Fleas and ticks not only cause discomfort; fleas can transmit bartonellosis or tapeworms. 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 over 18 pounds, and no prescription is 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.

* 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 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 5 months for flea control and reduced to 7 months for tick control.

    Keeps ticks from biting!

    I have used Serresto collars on all my dogs for years. These work great. My dogs have never tested positive for lime, proving the effectiveness of the product. The collars are fully adjustable and flexible for comfort. We buy a new one every year without fail.

    It’s super easy to use

    We have always loved these Seres to flea and tick collar. I’ve used it with my dog for at least three years and have never found a tick on her. I also like the packaging that it has it is easy to put on and easy to takeoff when you need to give your dog a bath or you’re ready for the next one.

    No more fleas

    Took a day to work. But my mom has no fleas. She likes the fill of the collar on her neck. , it matches her gray hair nicely. She says you can watch the fleas jump right off of her arm. Wish it came in different colors

    Great protection and zero issues after 5+ years!

    I’ve been using Seresto collars very year for the last five years, for my Goldendoodle. I live in the Upper Peninsula of MI where ticks are a huge issue. I’ve never found a tick on my pup when he’s had the collar on. He’s got very sensitive skin, is always itchy and has seasonal allergies. The collar has never bothered him or created any sort of skin reaction. I do take it off when I know he’s going to be swimming and when he gets groomed, but it goes right back on and everything seems to be fine.

    Soresto Large collar

    Bought this after trying capstar oral meds and having the flea infestation get even worse. I was doubtful of the effectiveness and did not like it’d always be visible but after having used it the full duration, I would definitely recommend. I will be purchasing another one and using this for her from here on out.

    🐜

    [This review was collected as part of a promotion.] Giving this 5 stars because I’ve heard great things and read great reviews- my dog was recently in the ER for a bacterial infection and has been heavily medicated so was weary on adding anything into his system too (even externally). But it definitely seems easy to use and doesn’t at all seem too tight or uncomfortable.

    Efficient and safe

    [This review was collected as part of a promotion.] This collar fits my German Shepherd perfectly. It can adjust the size and it’s soft. It has no strong odor. I like using this collar when I take my dog out.

    Product was well packaged. Have used this for my Cane Corso for the last two years and has worked extremely well. You can cut it to size so it fits properly and you do not have excess hanging off the collar. We live in a wooded area and I have never seen a single tick or flea on her since we began using this product.

    The only flea and tick protection I’ve ever used for my dogs. The collar is easily adjustable to your dogs neck and no irritation noted. Works effectively and I’ve never had issues with fleas or ticks since using this product. Highly recommended!

    It works for 8 months.

    We’ve had our little girl on this flea killer for 10 years now. She has never been bothered by those little parasitic vampires ever since. She wears it under her collar comfortably. It adjusts to fit her, just snip off the excess. Never had any skin irritation.

    Works really well

    The collar is smooth. And adorable it last when my husky scratch his neck. It works really good with all that hair. I just still didn’t have to worry about fleas. The instructions are very easy to follow. I had no problem fitting it to my dog and cutting out the rest.

    Does a great job serving its purpose!

    This flea collar held up really well for our large dog. We usually switch them out around the 6 month mark but they have done great for keeping bugs off of him! Easy to get on, easy to understand instructions.

    Works great for my 3 dogs!

    I’ve been using the Seresto flea and tick collar for my dog, and overall I’m pretty happy with it. It’s super convenient because you just put it on once and it lasts for months, so I don’t have to remember monthly treatments. I noticed a big drop in fleas within the first couple of weeks, and it’s been keeping them away well. My dog doesn’t seem bothered by wearing it either, which is a big plus. The only downside is the price, it’s a little more expensive upfront than other options. Also, you want to make sure you’re buying from a trusted seller to avoid fake products. Overall, I think it’s worth it if you want something easy and long-lasting that actually works.

    Easy to use, long-lasting, and very effective. My

    [This review was collected as part of a promotion.] I’ve been using the Seresto collar for my dog and I’m honestly really impressed. It was super easy to put on, and my dog didn’t seem bothered by it at all. She actually stayed calm and comfortable the whole time. Within a short period, I noticed a big difference with fleas and ticks, which was such a relief. I also love that it lasts for months, so I don’t have to worry about frequent treatments. The fit was perfect for my large dog, and it feels lightweight enough that she can wear it all day without any issues. Overall, this has been a convenient and effective solution for keeping my dog protected. I’d definitely recommend it to other pet owners looking for something low-maintenance that really works.

    Easiest way to prevent flea and tick bites.

    Serresto is an easy way to protect my dog from flea and tick bites. We have a collar where it fits inside snug to her neck. I love that its easy to use and can get wet on days when we swim. It does not irritate my dogs skin at all. Serresto is a wonderful way to protect our fur babies!
