Seresto Large Dog Vet-Recommended Flea & Tick Treatment & Prevention Collar for Dogs Over 18 lbs. | 8 Months Protection

f you’re tired of remembering monthly flea treatments or dealing with messy spot-ons, the Seresto flea collar might be your new best friend (besides your actual pet, of course).I!ve used them for my dogs (30lb, 50lb, & 160 lb) and here’s the deal: it actually works. It claims to protect against fleas and ticks for up to 8 months, and surprisingly, it kind of delivers. Within a couple days, I noticed way fewer fleas, and ticks? Haven’t seen one since.What I like:• Super low-maintenance – You put it on and forget about it (well, mostly).• No gross smell or sticky stuff – It’s not greasy, and you won’t smell chemicals every time your pet walks by.• Water-resistant – Bath time or a quick swim doesn’t kill the magic (though too many baths might shorten its life a bit).• Long-term win – It’s a bit pricey upfront, but if you break it down over 8 months, it’s cheaper than monthly treatments.A few things to watch out for:• Skin sensitivity – Some pets might react to it. Mine have been completely fine.• Not a bug shield – It doesn’t repel fleas and ticks, it just kills them once they make contact.• Fake products online – Definitely buy from a trusted store or your vet. There are some sketchy knockoffs floating around that don’t work (or worse).Bottom line:If your pet tolerates wearing it, the Seresto collar is a total game-changer. It saves you time, mess, and gives your pet long-lasting protection. Just keep an eye on them for the first couple days after putting it on, and you’re good to go.

At first I was worried about if I could get a legitimate one or not from Amazon; but they came in sealed containers and they work well.The only issue I noted was lack of appetite at first. That evened itself out. So far we are almost at the end of May 2025 and both of my (very large!) dogs have zero fleas or ticks.I live in an area that has a lot of ticks that carry Lyme. For that specific reason, this is absolutley a great option, and the cost is worth what it does.I haven't noticed any scratching or anything like that, it fits well and has extra loops to secure it.Pro tip from me, tuck it under their collar to keep the rain from getting to it, and keeping it up against the skin. But make sure to check if this works, because in my situation my dogs have very thick hair (great pyrenees), so your mileage may vary with the above suggestion.Recommended!

I was nervous to buy this bc all the reviews & it’s the most expensive but I was desperate! I can only speak to fleas (not ticks) but this worked for me!! I previously tried many other things & still found fleas on my dog & in my bed! I put this collar on & they were gone. I still comb him every time he comes inside & wash bedding more frequently so that may also help but I’m so thankful they’re gone!

I swear by Seresto flea and tick collars! These are the only ones I will buy. They work excellent for my Australian Shepherd and my AussieDoodle. They do not irritate their skin and they keep a majority of fleas and ticks off of them. We live in a field in the middle of the woods so ticks are abundant and they have very minimal issues when using the Seresto collars. Definitely my go to for tick prevention.

Our vet warned us that many dogs have had seizures from Seresto collars, some of them fatal. I was worried when I googled this issue. But this collar has worked great for our 65 lb. pit bull. No health problems or concerns at all. And best of all, no ticks - and we live at the edge of some woods. And it's super easy. I put the collar on in March and it's effective until November. Just one caution: TAKE IT OFF BEFORE YOU BATHE YOUR DOG. We forgot to take the Seresto collar off before a bath and our dog was sick for three days. I guess the soap and water released too much toxin from the collar all at once. We kept dousing our dog's body with lots of cool, clear water and he finally recovered. But that was scary.

My dog was a tick magnet before this collar. The liquid Frontline did not work, pill form did not work. Serestro is the best for keeping ticks and fleas away. Great fit, good size. Has a nice light, almost floral smell. My dogs did not have any issues with rashes or feeling sick. Perfect for my fur babies. *Please monitor your pets when giving them this collar. While I have had success with both my 90lb dog and 8lb dog, you should always watch to see how your pet responds to a flea collar.*

I’ve had my dog wearing one of these collars for around 6 months now and it doesn’t bother her or irritate her skin at all. She’s been in water and had baths since having it on too and it’s holding up well. We just recently went to the park, got home and noticed a tick on her ear. I grabbed tweezers to get it off and to my pleasant surprise, it was dead! The ingredients in the collar must have done their job in killing the tick! I am so relieved. So far I have not noticed any fleas either. I love that this is an effective, affordable option for flea/tick prevention for my dog, as the topical treatment can be so expensive. Definitely recommend.

This collar works better than the topical treatments! My Vet recommended this for my Belgian Malinois that is severely allergic to flea bites. My Vet office was selling this large flea collar for $77.98! Thank God for Amazon! Here I was able to actually afford the collar, being on a low-income budget! Thank you, seller!
