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.

I live in an extremely rural area in the south and during the spring and summer it gets very hot and very buggy here. For the past couple of seasons, we have had a really bad flea problem. The ticks haven’t been as bad as I have seen them but the fleas have been awful. I currently have two dogs and two cats. My dogs, both rescues, are very large dogs. One is a 90lb German Shepherd Dog and the other is a 160 lb Golden Retriever/Leonberger mix. My German Shepherd Dog has a severe flea allergy and has been struggling with hair loss and extremely itchy skin because of the high flea population we’ve had the past couple of years triggering his allergies. I tried everything: natural flea killing remedies for inside the house and treating my lawn to help minimize the chance of one of the little buggers hitching a ride on him when he goes outside. I have him on just about every flea pill I can think of from my vet. Comfortis did OK during the winter and late fall/early spring. Once the season got into high gear, it didn’t seem to make much of a dent into the fleas. Same with Trifexis. Frontline worked about as well as the others. Between flea and heartworm meds, I was spending $100 a month of preventative care for just my two dogs. Having used Advantage about 10 years or so back on another dog I had at the time when we had another serious flea year I thought I’d give it a try again.I had read about the Seresto collar and how it would take care of fleas and ticks for 8 months and since Advantage had worked for me in the past I thought it was definitely something I should be looking into. I couldn’t buy it at my local vet as they don’t carry it so I turned to amazon. I read through the reviews and liked what I was seeing. I ordered one of the collars and impatiently awaited its arrival.As soon as the mail carrier put it in the box I was on it and put it on my German Shepherd Dog since he is most severely affected by the fleas. Because of his size, I didn’t even bother trimming the end of the collar. One of the reviews mentioned about a 10 day period for the collar to really start to work but my experience with it is a little different. I started seeing dead fleas later the same day I put the collar on the dog. The flea problem had gotten so bad in the house that I was ready to call an exterminator to try and eliminate them. Every living thing in the house was scratching thanks to the fleas. Within about a week of putting the collar on just one dog, all of that stopped. I still see a flea from time to time but that is usually after we come back inside after a walk or playing. There are no more fleas in the house. Even places the dogs and cats don’t go, the fleas are gone. I had planned on buying another collar for my 160lb dog but with the way this one has worked, I don’t really think that will be necessary. My German Shepherd Dog is getting his hair back slowly and he’s not scratching all the time. He’s sleeping better–everyone is sleeping better.I know with the economy being what it is right now, I understand completely that $50 for a flea and tick collar may seem like a lot to spend at one time (that is one of the reasons my local vet doesn’t carry it because a lot of their customers can’t afford it) but it is very well worth it if you have a flea and/or tick problem. My $100 a month preventative bills went down to $30 after purchasing this collar. This works out to around $6.25 a month for the best flea and tick protection I’ve ever found. There aren’t any pills to con the pets into eating (no more fixing peanut butter sandwiches to get the pills eaten!) or no messy topicals to apply.I am absolutely sold on this flea collar and will not ever use another brand of flea and tick preventative again. This is the only solution for me. All of the positive reviews on this site for this collar, believe them. The praises they are singing are absolutely spot on.Edit, 4th September, 2014: I wanted to come back in and update my review since it’s been a couple of months since I purchased this collar and put it on my dog.The collar has worked beautifully! It is still killing fleas and ticks like it promises, my dog has not had any allergic reactions to it (something I worried about as another reviewer commented their dog did react) and my home and surrounding area is completely flea-free. I wasn’t expecting this one collar to kill all the fleas in the house with four animals running around in here, but it has. My GSD has almost all of his hair back and I can tell a huge difference in his personality. He’s more playful and happy all the time like he used to be before he had his awful allergic reaction to a flea bite. The only chewing or scratching he does now is where his skin itches from the new growth, and that scratching/chewing is decreasing steadily. I haven’t seen a single flea in well over a month and I don’t even worry about picking up any buggy hitchhikers when we go for walks anymore as I know the collar will take care of them. My biggest worry now is my GSD playing in the poison ivy. 🙂

This collar is PERFECT. Okay so I was really really super skeptical about buying this for several reasons:- I hate the thought of my two pups having to constantly wear an extra collar- I’ve tried the flea/tick collars from Walmart and they were greasy and had a weird smell but even worse, they did NOT work.- I’ve read some of the horrifying reviews- I’m just a skeptical person and simply didn’t think this would work.BUT IM A BELIEVER NOW.For context, I have a 3yr old short haired ~45lbs pup (pitbull, lab, corgi mix) and and a 7yr old long haired ~30-35lbs pup (Lhasa Apso terrier mix). I live in Maryland where the weather is just always unpredictable. I feel like we have like 6 seasons instead of 4. We have woods in the back of our house which deer always like to frequent, along with a swamp/pond across the street. This spring and the start of this summer we had a monsoon season where afterwards, there was an annoying infestation of ticks (mostly Lone Star and Deer ticks). It was disgusting. I legitimately could not take my dogs out for a walk without finding at least 4 ticks on them afterwards and on me!!! And this is on top of treating my dogs with the monthly tick/flea topical oil treatment. That’s how bad it was, which is what prompted me to buy the Seresto collars. (I bought Large for both of them)Once I did and placed them on my dogs, after maybe like 1-2 days, I have not found a single tick on them. I know that sounds so far fetched but I don’t know what else to say because it’s absolutely true. It does take about 1-2 days for the medication to get into the system (from experience and from *I think* what the package said) because I still did find a few ticks on them the next day. But after that, not a single tick! They’ve been wearing the collars for about 1.5 months now so I’m still keeping an eye on them (I plan on updating this review after 7-8 months to see if the claim of lasting 8 months is legitimate). Right now though, I am sooo happy.Now I want to address some of the other reviews I saw. After I saw some of the pictures of rashes this collar left on some dogs, I was worried, especially cause my smaller one already has exist in skin issues. But both are doing perfectly well with no skin issues from the collar. I don’t want to be presumptuous and I may be totally wrong, but I’m thinking maybe the rashes the other dogs had were because they’re not used to wearing collars? So they just kept itching at it? Maybe? I say that because for me at least, my dogs are used to wearing their regular collars nearly 24/7 since they were babies. So when I added the Seresto collars, they were unphased. But then again I’m also aware that just like humans, each dog reacts differently. Luckily, My dogs have no rash problems from the collars.As for some claiming that the collar doesn’t work.. I’m not sure what to say other than that they really truly work for my dogs, and I live in a heavily tick infested area. It really is like night and day in terms of how well this collar works at preventing tick bites. Especially with my long haired dog since ticks would easily hide in her fur.The collar isn’t greasy nor does it have a strong emanating odor. BUT it’s still medicated so it still has a very slight residue to it but nothing that interferes with everyday life.I’m sold and plan on continuing with this product from here on out. NO MORE GREASY NASTY SMELLY TOPICAL MONTHLY TICK GREASE!**Side note**Make sure you read the packaging instructions carefully!! They mention a few things like about how the efficacy is shortened to something like 5 months for dogs who swim a lot, or how the collar is designed to unlatch if the dog pulls incase it gets stuck on something (which I thoroughly appreciate) so you CANNOT substitute this as a walking collar! The collar DOES unlatch if you hold onto it and your dog pulls (personal experience: guests came over, one jumps and I accidentally grabbed the Seresto collar and it unlatched). But you CAN reattach it!! So definitely take the time to read the package instructions.Hope this helps! I really loveeeee this collar. THANK YOU SERESTO!!!

Works well and is a great product for our dog! Have a 140 pound dog I purchased the large size. I went to the store where this product was more expensive to check on size!! Great value- so much cheaper than in the stores.

Best Otc Flea and tick on the market, easy to put on, lasts 8 months and prevents fleas and ticks. I’ve heard that it doesn’t work for all dogs but it works great for mine. MAKE SURE THE COLLAR IS TIGHT ENOUGH! Obviously don’t choke your dog with it but make sure there is a little bit of contact or it won’t work.

This is a great flea collar that we have been using on our dog and cats for several years. It works well and our animals have mot had negative reactions. The only negative I would say is that the flea collar does not work for the 8 monts advertised. For as long as we have been using these (since 2019) the collars stop working after about 6 months. That is still good and why we keep buying them but I do think it is important to know that you will need to repurchase a couple months sooner than advertised.6 months of coverage is still worth the cost though.

I got these for my dogs towards the end of last summer. Fleas were worse than usual last year and nothing seemed to get rid of them. They were completely gone in about a week and I haven’t seen any since (it’s spring of the following year now). One of my dogs has sensitive skin but no skin irritation at all. If your looking for a long term fix for fleas this is it! It holds up well, super effective, and size adjustable.
