With its innovative delivery system, the Seresto Flea & Tick Collar for Large Dogs & Puppies (over 18 pounds) offers a breakthrough in tick and flea control for dogs for 8 months. Inside the unique polymer matrix of the Seresto collar are two active ingredients: imidacloprid, which has been used in products recommended by veterinarians for years to control flea infestations, and flumethrin, which effectively repels and kills ticks, larvae and nymphs. These ingredients work together in this unique flea collar to provide dual action against fleas and ticks like no other treatment!

Rated 5 out of 5 by A great value I have 7 dogs in my home. I have been struggling for years with the effectiveness, cost and difficulty of applying topical flea/tick treatments. My dogs hated them! Pill treatments didn't work well either. I first purchased Seresto from a company in the UK (before finding chewy.com) to test it with 2 of my dogs. Within days their fleas were gone and their skin irritations started to clear up. It was like the miracle I had been looking for. We also had a problem with ticks, but not anymore. And by the way, mine actually did last the entire 8 months advertised. Because it really works for me, it's the most cost effective solution I've found to date (it costs about $5/month per collar from chewy.com). The collars contain the same dosage so I'm able to split one large collar into 2 smaller ones (the only differences are the large collar is wider and longer than the small). No more stressful applications of topicals for any of us. I hope I'll never have to use anything else. July 21, 2016
Rated 5 out of 5 by Awesome Product Highly Recommend! I highly recommend this product to anyone. One of our dogs gets deathly ill with oral flea products and tried this product at the recommendation of our veterinarian--she was right simply a great alternative. Seresto is not an alternative it is the only product we use for her, more importantly it works, it is affordable and less expensive than any of the oral medications without the side effects. I have recommended this product to more than 25 friends and relatives and not one of them have been disappointed with the product. My only negative about Seresto? It does not offer bling other than a few reflectors for night safety. When she steps out on the town or farm she is without fleas and ticks but not as stylish as I think she could be. Living on a farm she is exposed to a lot of flea and tick and its a non-issue. But when out on the town I wish it was maybe in a color option at least. Great product I highly recommend Seresto!

Rated 4 out of 5 by So far so good Its only been a couple weeks so cant say about longevity but the fleas were gone in two days. I have 3 big dogs a thick,long hair shephard, very short hair pitty and a hound, reg hair. I live in the country with woods close so they get into areas that have fleas and will bring them home. This year was like overnite attack of those buggers! I cant afford the monthly anymore so had heard good things about these collars and even if they last for just 5 months they will be a bargain as Chewy had them for $40.!! The biggest complaint i see with these is that they dont stay on well. I fixed that problem! After you put it on DONT cut the excess off! The end will actually stay curled and wont be able to slip thru. You can also slip the end under the collar and due to length it will stay put.I have had to tighten once on my short hair dog but was never any chance of it coming off. So this collar does the job of killing fleas, we'll see how long it lasts. June 2, 2016
Rated 2 out of 5 by Would not recommend for tick protection, fine for fleas. It's June and I am not due to replace my black lab's collar until October. We haven't had any fleas, which is great, but hadn't had a chance to really test how the collar repels ticks until a few days ago. We went backpacking this past weekend in an area that was invested with ticks, and so was my dog. We ended up pulling at least THIRTY ticks that had attached themselves to her and we are still finding them! After returning home, we ended up treating her with half a treatment of Frontline. As you can imagine finding ticks on a black dog is extremely difficult so we're still pulling ticks off of her. We're saving the ticks in a couple of baggies in case she shows any sign of illness. Interestingly, the ticks we saved from the weekend are still alive in the bag. However, the second bag of ticks post-Frontline treatment are dead! Please do not consider this if you live or go to areas with ticks. June 7, 2016
Rated 5 out of 5 by Finally, something works! This product is great! My parents elderly dog is highly allergic to fleas. Last year they tried most of the reputable flea products available, and NOTHING worked. The poor dog (australian shep/border collie) lost all of her hair, and was chewing herself bloody. Flea baths were killing thousands of fleas, but she was getting reloaded somewhere on their farm. Antihistamine was doing very little for the symptoms. It was so bad, Vet recommended putting her out of her misery and euthanizing her, but he had one more thing to try-Seresto. It was great! Now 7 months later, she has most of her hair back and is just now starting to scratch again. Time to order a new one. I know this sounds like an infomercial, but it is the truth. If I had not seen it, I would not believe it. July 17, 2016
Rated 5 out of 5 by Good quality collar! I used to buy Frontline plus. Excellent product no complaints but it was a pain to get the drops on my dogs skin instead of having it drip all over his coat! Also had a hard time remembering to apply the drops every month.... I decided on this collar and I love it. Its a very sturdy collar, waterproof and good for 8 months! Wow! I like that! It comes in a really nice tin container with excellent information. Very happy! My dog (85 lb black Labrador) is loving it too! Have not seen any fleas or ticks. My dog is outside a lot and swims once a week. I will keep purchasing this product! July 21, 2016
Rated 5 out of 5 by So far it's great. I have never used these collars before but it was recommend from a friend who has used it on her older dog for quite some time now. So far (2 weeks) we love it. It doesn't have any odor and it doesn't seem to bother our dog and we haven't seen any signs of fleas since she has been wearing it. Plus it was much cheaper than what the friend paid for hers.

Rated 5 out of 5 by Great option for flea and tick coverage in the south The Seresto Collar works great on my dogs. No messy liquid and it keeps the fleas and ticks away like magic for months, even in the south. We have plenty of exposure to fleas around here, as we foster dogs all the time. None on my dogs and none in the house though! I give my dogs Sentinel for heartworm protection and the 2 work great together for parasite protection and healthy dogs. July 21, 2016
