Description

The Seresto flea and tick collar for dogs provides continuous 8-month flea and tick protection. Unlike oral flea and tick prevention products that require a bite, the Seresto collar repels fleas and ticks and kills through contact; no biting required. Frontline flea and tick treatment does not repel (based on label claims). Seresto dog flea collars contain active ingredients imidacloprid and flumethrin, which are slowly and continuously released in low concentrations, spreading from head to toes, even the tail, over your dog’s coat and skin. Seresto flea collar for dogs is water-resistant and remains effective after shampooing, swimming or exposure to rain or sunlight. (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 five months for flea control, and reduced to seven months for tick control.) This vet-recommended flea and tick collar for dogs is odorless, non-greasy and easy to apply. It can be used alongside other identification or restraining collars without damaging them. Avoid the hassle of messy monthly treatments and get the effective protection of Seresto dog flea and tick collars. Also available: Seresto flea and tick prevention for cats.

Directions: How to apply the Seresto collar on your dog 1. Remove the collar from its packaging. 2. Unroll the collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain. 3. Insert the end of the collar through the buckle and loops. 4. Adjust the collar around your dog's neck until it fits comfortably on them. 5. Two fingers should fit beneath the collar and neck to ensure it's not too tight. Any excess length of the collar beyond an inch past the loops should be cut off, unless it is on a growing puppy, where some additional length may be needed for adjustment as the puppy grows. 6. Check periodically and adjust fit if necessary, especially on growing puppies.

    • Worked on 7lb Papillon when Advantix drops did nothing
Size: 1 Pack
I have always used K9 Advantix on my dogs, and never had problems until the year I started camping in Northern Wisconsin. Now, let me just say -- the K9 Advantix worked PERFECTLY on my large-breed dogs - never a single flea or tick. Knowing that we were heading into a tick-infested area, I put the Advantix drops on my 80 lb german shepherd and my 7 lb papillon a week before camping. After a walk in the woods, I found one tick clinging to the outside hair of my german shepherd, not attached -- easy to just flick right off before we went in the house. We didn't find any ticks on the papillon until we went home. First found one tick within 24 hours, had to remove it with tweezers but figured, hey, maybe it hadn't attached long enough to get killed by the Advantix. Then found another after 24 hours. And another after 48 hours (by that time it was engorged). Clearly the Advantix was not working on my papillon, though it seemed to be working on my large breed dog. Perhaps the drops, being such a low quantity due to his size, didn't absorb properly. But I wasn't about to joke around with ticks and lyme disease, so I started looking for alternative options. The day before I ordered the Seresto collar, my dog picked up a tick in my own backyard, in the city of Milwaukee, with mowed grass and everything. That was it - I was going to risk my fear of collar side-effects, watch my dog carefully, and get this collar. Fast forward 10 days after wearing the Seresto collar. No side effects (I checked FREQUENTLY for signs of rashes/redness/lethargy/hair loss), and we found a dead tick (not yet engorged) dead in the house. I'm convinced it was the Seresto collar, given that the small dog is the one who already picked up 4 ticks, while the larger dog barely picked up one. The large dog is still using up what's remaining of my K9 Advantix, but I'm likely to switch her to the Seresto collar next year. The convenience of having one collar for the whole non-winter season, the fact that it seems to WORK on my small-breed dog, and the cost per month for the collar vs the drops has sold me. I think the drops work fine for large breed dogs, but can fail due to miniscule dosage amounts on smaller breeds. The collar is safer for my dog when it comes to lyme disease, compared to the risk of side effects (which you should be on the lookout for with both drops and/or collar during the first few days of application -- anyone can have a reaction to medicine if they're allergic). Seresto has sold me on their collar -- now all we have to do is repeat the camping experience and see how long the collar lasts. Happy camping! ... show more

    • It works but frequent baths may diminish potency
Size: 1 Pack
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. ... show more

    • Best Flea Collar. But dont expect 8 months.
Size: 1 Pack
Worked great initially. Purchased on Sept 1st. Its now December 8th and my dog has fleas again so for sure dont expect it to last the full 8 months. However that being said, this is the best flea collar I have ever tried. When it does work, it works 💪🏽

    • Seresto and only Seresto for my fur-babies.
Size: 1 Pack
Best flea collar made. Tried two other cheaper collars. Not going through that disaster again. And definitely not giving a supposedly safe oral treatment. Have you read what’s in those oral preventatives. Yes, Seresto is more expensive but I have found and the vet said it’s the best and safest flea collar made for now. So I keep an eye out for when it’s on sale/has a coupon and buy the next one ahead of time. The vet also informed me there is one that has not gone through approval yet but when it gets to market it is going to be the most effective and totally safe except for a rare incident. I’m looking forward to that. ... show more
