Goodbye NexGard!!

Six months ago I chose this as the flea protection for my blue heeler, it impressed me so well I discussed it with my vet and with his seal of approval on this product(he says they love them as well), I'm now back to choose this as my flea and tick protection for my seven pound toy poodle. No more internal monthly chemicals - Goodbye NexGard! My heeler has literally been 100% flea and tick free ALL spring, summer, and fall and this collar is still going strong. LOVE LOVE LOVE these! EDIT >> just to clarify I first purchased the large dog version of the product and upon return I purchased the small dog version.

Reliable flea and tick control

Going on my fourth year using these collars for my 4lb Chihuahua and 12 lb Terrier and they work great. I live in a very tick populated area of the NorthEast and these collars have been a real help. I pop them on around March and they don’t come off until November. My dogs stay flea and tick free all season long. Be sure to leave at least a thumb width of room when sizing to your pet or you’ll struggle to cut it off. The locking system sort of works like a zip tie and won’t back out once engaged.

Best Long-Lasting Flea/Tick Collar that Really Works!

Best collar I ever used for my dogs. They do last the 8 months as stated. Only thing was, I had ordered 2 new ones & they did not come with the reflective tabs that go on the collar. I was able to remove the tabs from my previous purchase of Seresto collars, so all is fine. I don't know why they weren't included with the new ones. Am overall happy with them & would recommend to anyone with dogs or cats.

No more fleas!

Ordered this about four days ago and NO FLEAS! I was picking fleas off of my little pup every day and now that the collar is on, NONE! Im so happy and I know my little pupper is too! We have four chickens, and live next to an empty field so fleas have been a major problem. I have a 16 year old papillon/chihuahua mix. He was sick from topicals so I've been skeptical to use anything with chemicals. He has a history of skin problems as well, but his fur is fluffy enough right now that the collar doesn't rub too much on his skin. So far so good! UPDATE: it's been a month since purchase and still not fleas! I literally see fleas jump on him while walking and they jump right off. This product really works and I will continue to buy until proven otherwise :)

It works but frequent baths may diminish potency

This is a review for Bayer Seresto dog collar for small dogs: This purchase was made a while back. I am only now entering my review because 1) time is an issue for me 2) I can now share with near certainty that the product works. First a little history: sometime last year we missed the 30th day dose of the Frontline that we were using then. Unfortunately those couple of days turned into an unwanted turning point. Within about a month we were seeing little crawly things on our sweet little pooch. In no time we had a major flea infestation in our home! We continued with the Frontline but were not seeing any results. So we did various non-flea bomb things: we went to great lengths to get rid of the fleas inside and outside the house, we bathed our dog frequently, we combed out the disgusting bugs on a daily basis, we got the Seresto collar and we stopped the Frontline and switched to Nexgard. Our problem went away in about 4-months. Long time right? Well, fleas can linger for a while so don’t think you can get rid of them so easily. You might think that our problem was resolved because of the Nexgard (which also works) but I think our problem was resolved because of both. Since our problem was so severe, at the recommendation of our vet, we bathed our dog a lot. Poor thing. The fleas really did a number on her skin and coat. The thing with Seresto is the directions call for infrequent baths. This, we found out, is because the chemical effect has to ‘restart’ each time after a bath. This is where the Nexgard came in as a backup or insurance. Our problem was extreme so the baths for our darling Cavalier were necessary – we used a special antiseptic shampoo that helped her skin and killed the fleas that were on her. (Of course, after a few hours back in the flea environment, they jumped on her again.) As we understand it the collar works by releasing an agent that coats the animal’s fur. This is what kills the fleas before they bite. So if you’re bathing your dog frequently, be aware that the collar’s strength will diminish and may not ‘work’ for a day or two following the bath. The collar may then need to be replaced more frequently too, because it is ‘using up' the chemical faster. Instead of every 8 months, it may be every 6 months. If all you need is maintenance then you should be alright. But if you’re battling a problem like we were, multiple approaches like ours may be necessary. On the flea infestation in our home, we researched every piece of information about getting rid of fleas and applied all that we learned. We talked with a number of customer service reps, wonderful all of them, both at Frontline and Bayer (the makers of Seresto) and even corresponded with a few of the world’s top vets and scientists in the field of flea management. Fighting home flea infestations is a task that requires a lot of work, time and persistence. Killing the adult fleas is not enough. One must make sure the pupae are also eradicated. This next to last life cycle of the flea is the one to fear. Pupae can remain dormant for up to 6-months, hiding in crevices and maturing into adult fleas, months after you’ve stopped fighting. The ideal is to do everything to get rid of the adult flea so that they do not lay more eggs. For us that was the collar and the Nexgard. Focusing on the pupae throughout is recommended too. Since they can linger in your home dormant, you want to stop them from growing into adulthood 6-months after you think you got rid of the problem. Once the pupae mature, they ‘wake’ up, sense the warmth of your pet, jump on your animal baby and start the cycle all over again. In the heat of the infestation, we would sprinkle and rub salt and diatomaceous earth in all the crevices and large swaths of the carpets. This would sit for a few days (yes, a bit problematic when walking over it but well worth it, I tell you.) and then vacuum well. We’d repeat this every 2-3 days for weeks. We’d also launder sheets, and doggie bed covers, and any fabric on which our dog would lie, in hot water, frequently. In order to gauge our progress, we set up a few desk lamps on the ground above aluminum dollar store food storage pans filled with soapy water. This way we could see if the fleas were dying off. Fleas get attracted to the warmth of the light, move toward it and of course they can jump as high as four inches so in they would go into the water. I guess the soap would kill them. Over time, the dead fleas in the soapy water diminished to the point that we knew we had won the battle. No dead fleas in the water meant no more adult fleas in the house or on our dog. With the continued vacuuming, I believe we got rid of the pupae as well. Of note, the vacuuming is also like an earthquake for the fleas and the pupae, stimulating them, making them jump all over the place, allowing them to be sucked up by the vacuum faster. So I say, among other things you can do to combat a bad flea infestation, vacuum, vacuum, vacuum, every 2-3 days if possible for a while, launder everything frequently in hot water, place salt and/or diatomaceous earth in the crevices, use the soapy water pan idea and keep your animal away from shady areas in your backyard because fleas love to live there. They won’t be in the sunnier parts. (We used inexpensive garden wire mesh.) Oh and be careful vacuuming the diatomaceous earth because this could ruin your machine. I used to go easy on the powder. You don’t need a lot. And if you have a bag vacuum, get rid of the bag each time because if you leave it sitting there, the pupae and fleas can get out of the bag and return to your dog. We have a Rainbow vacuum which uses water so dumping the water was much easier than changing a bag each time. Anyway this was my family’s experience with fleas and the Seresto collar. We continued with both collar and Nexgard for a while and never saw a flea again. The Nexgard by itself could’ve been ok but I truly believe in the collar since it is not at all like the traditional dangerous collars of old that are still being sold today. I think if we had had the Seresto from the beginning, we would not have suffered as we did. It’s also so simple. Put the collar on and forget about it for 8 months! Now I will never go back to drops flea control. I hope some of this is helpful. When we were going through our flea trauma I relied so heavily on these types of reviews that I wanted to “pay it forward.” Good luck to you.

Frontline and Advantage II failed... this wins!

We live in SE Houston and the coastal fleas have become mutant super villains bent on world domination. Frontline stopped working completely. Advantage II only works for a week at a time-- too much cost and chemicals for your pup. I was starting to think Kona would just have to endure a lot more baths when I talked to a breeder about what she uses for her show dogs. Instantly she replied "Seresto. Trust me, you'll be glad you did." I have seen the pictures of dogs who have a negative reaction and kept a very close eye on her neck for the first week. Genetics are probably a factor, but I think some of the issue is whether or not your dog has enough fur between the collar and their skin. I left this loose enough that her medium length coat is layered between at all times. The first day I combed her and found a few dying fleas. It took about a week before I stopped finding any at all, alive or dead. Give it some time to work and realize you probably have a lot in the environment that need to have the opportunity to jump on your pet and die. Good riddance! UPDATE: When our second dog (golden retriever puppy) rapidly outgrew his size small, we got him the larger collar. Within a few days, I could feel little bumps around his neck and knew it was an early sign of a reaction. I attribute this to the greater width of the new collar and the fact that he still has some "puppy fluff" instead of all is adult fur yet. The bumps have since scabbed up, but they are very minor except for causing him some discomfort and making him want to scratch often. Kona (small mutt!) still has no issues whatsoever. I am not changing my review from five stars because this collar WORKS when nothing else has been on our fleas. We will try again with our golden when he grows some more fur coverage and update again. Keep a close eye on your pet if you are just starting use of this product.

Great prevention.

When they say small they mean small. An old dog with a saggy neck who might otherwise fit it weight-wise will not. I used it for a cat instead and since there are no medium sized collars ordered a large. Seresto collars are impressive in their ability to keep ticks and fleas off for three quarters of a year. Mathematically it's cheaper than topical and seems more effective (Frontline is my second choice, or Revolution which treats more parasites), and of course it's more convenient. Be aware of proper collar usage and monitor pet for issues related to reactions or being too tight or too loose. I realize this is under dogs, but I'll quote my veterinarian since we recently ended up talking about Seresto collars (and cats), and I don't think you can get a better endorsement from a professional, "Any flea collar brand other than Seresto would kill a cat before it would kill a flea or tick." I've been using these for 3 years now I think, and other than in general being nervous about collars on unsupervised animals, have had no problems except one cat came home without his on once. They're supposed to slip off if they get caught on something, so I guess it worked. If the animals don't get ticks that means the people in their house get fewer tick bites too.

No smell, 8 month protection, best tick collar ever!

Best flea/rock collars on the market. No smell whatsoever. I buy them every year in February for my two mini Australian Shepherds and they do the trick for the whole year. They each weigh 20 pounds and I buy the small dog ones. We have ticks very bad here and we will occasionally find a dead one on the dogs or sometimes a live one that just got there - but never ones that have attached.

Takes a few weeks to get used to; very effective for 6 months (not 8 months)

My dog is a 6-lb Chihuahua mix, age 8 years. She is a flea magnet. I tried the back-of-the-neck oil treatments: she got sick for days, I guess because she is a major self-licker. When I tried Seresto, she only got sick for one day, whereupon I removed the color, bathed her, and gave her a break from the collar for two days. After that I put the collar back on only during the daytime and she was fine. I would find a flea sometimes, but always under her butt where there is no fur, so they were easy for me to pick off with soaped fingers. After two weeks, I started leaving the collar on throughout the night too, and she was fine. During the sixth month of her round-the-clock Seresto collar usage, I found fleas in her fur again. This was during the summer, just after the hottest heat wave of the year, temps over 100F outside and over 85F inside. I ordered a new Seresto collar and initiated a subscription at a 6-month interval. She is now wearing the new Seresto collar round-the-clock and the fleas are gone. Just like that, the fleas are gone, I tell you! My guess for now is this: it took a few weeks for my dog's body to get used to the Seresto collar chemically. After that, the Seresto collar works very well and keeps the fleas off when it is worn 24/7 except during and right after baths. The collar is effective for 6 months at a time, not the advertised 8 months. A $50 anti-flea product that lasts 6 months is still a great deal in my opinion.

The fleas are gone!

I have a small long haired Havanese mix and had tried Frontline and Advantage with no success. Frontline did nothing which really surprised me as it has worked well on my cats in the past. Next I tried Advantage which helped some for a couple of weeks and then the fleas would come right back. My dog is also around my dad's two labs which he does not flea treat and made it even harder to keep fleas off my dog. I even treated his dogs and mine at the same time with advantage but it only lasted a couple of weeks(I would still see a flea or two) and was expensive. I was nervous about the bad reviews featuring lethargic dogs, seizures and neck sores for these collars but desperate for some flea relief so I went ahead and ordered it. My dog his thin skin and non shedding hair without underfur but happily the collar has not bothered him at all! The best part is ALL the fleas were gone within 24 hours and have stayed gone for weeks! This is even with him being around non flea treated dogs daily. It's amazing! I've been checking his neck often and it's perfectly clear and fine too. I put the collar on as lose as possible so it lays over his long hair and is not rubbing against his skin. Also it is easy to remove for baths. I take it off as he needs baths once a week as we live in the country and he is mostly white and gets muddy. I forgot to put it back on for two days and the fleas still stayed gone. I'm so happy to have something that really works!
