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. 7. Seresto comes with three optional reflector clips that can be attached to the collar to help keep your dog visible at night. The reflector clips should be evenly distributed on the non-overlapping part of the collar.

Product Description

Give your dog long-lasting protection against fleas and ticks with a Seresto Small Dog flea and tick collar. Unlike other flea and tick protection, Seresto Small Dog flea and tick collars kill and repel fleas for eight continuous months. Seresto Small 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 Small Dog collars make your dog’s comfort a priority by killing on contact, so pests don’t have to bite your dog to die. Existing fleas die within 24 hours of application while reinfesting fleas are killed within just two hours – before they lay eggs – preventing further flea infestation. Re-infesting ticks die in as few as six hours, and tick infestations are eliminated within 48 hours of the initial application. Seresto Small 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 and aid in the treatment and control of Sarcoptic mange. Fleas and ticks not only cause discomfort; they can also transmit bartonellosis, tapeworms or Lyme disease. Check the product label for information on potential side effects.

Seresto Small Dog collars are for dogs at least 7 weeks old, and there’s no prescription needed. They’re odorless, non-greasy and water resistant to swimming, exposure to rain or sunlight, bathing, and shampoo treatment.**

Seresto Small Dog is a trademark of Elanco or its affiliates.

*Elanco Animal Health, data on file

**Seresto Small Dog is water resistant and remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for 8 months. In order to maintain an eight-month duration, 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 5 months for flea control and reduced to 7 months for tick control.

I was skeptical whether this worked or not so I went and tried it. After the first few hours I did not see any improvement on my dog. But after taking her on a walk and I checked her she did not itch and no sort of fleas on her. So it works but it might be different depending on how big your dog is. I Highly recommend.

We have been using these collars for last 5 years or so and they work excellent. It ends up cheaper than using the flea pills monthly and it has no smell or residue it leaves. Just watch out for fakes if you order from other sites like ebay or others because last year I got one off ebay that was definitely fake and smelled like really strong cinnamon.

Years ago, my vet told me fleas and ticks were starting to build immunity against normal frontline drops or monthly chews. I switched my dog to the Seresto collar and never looked back. It may feel expensive, but it lasts 8+ months. We go on hikes, to the beach, play at the farm - she has never (knock on wood) had a tick or an issue with fleas!

It works but frequent baths may diminish potency

Reviewed in the United States on June 18, 2016

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.

0/10 Dangerous product health wise- allergic reactions in every animal we used them on.

Reviewed in the United States on August 20, 2020

Color: GraySize: 1 PackVerified Purchase

Please be cautious of using these collars, we had a terrible expirence.

My mom and I both purchased sets of these collars, for dogs and for cats using the appropriate species specific sets, as flea prevention. Both households have dogs and cats. In total we spent close to $150 dollars each and subscribed to auto renew the purchases due to the really great reviews.

The first 2 days they seemed to work really well! We found some dead fleas on the dogs after they came in from outside and no living fleas anywhere. Day 3 my moms Labrador began itching himself constantly- mostly around his neck and back. Hes older with some food allergies so we at first thought he got into something (as hes notorious for eating trash and sneaking cat food) and did not connect it to the collar. We kept an eye on him and over night he developed large weeping sores everywhere the collar touched as well dry itchy spots along his back and chest. Those spots later developed into sores and the poor guy was miserable. Knowing he's prone to allergies we removed his collar and bathed him/treated the sores but left the collars on Every one else as they didn't react similarly and chalked it up to being a fluke due to his pre existing allergy problems.

That was, however, not the case. Over the next 3 weeks everyone we put a collar on began digging/scratching themselves raw (4 dogs, 7 cats total between both houses). My oldest cat developed large weeping sores everywhere the collar touched and she did not previously have a history of allergies. Ive used collars on her in the past and she never had a reaction. She lost the fur around her neck (as of now about 2ish months later its still not grown back) and had a decreased appetite as well as becoming very lethargic. 2 other cats developed bald spots and sores on their necks where their collars touched while the rest continued to develop bald spots/red and itchy skin.

I have two daschunds and at the same time that we discovered the balding/sores on the cats, my male daschund very suddenly developed Hemoragic Gastroenteritis. He previously had a clean bill of health but very suddenly became extremely lethargic, refused food and water, was vomiting and had bloody, jelly like stool. Wednesday night he went to bed fine, ate dinner and was playful. Thursday morning he refused breakfast, and by that afternoon/early evening he wouldn't move, eat, drink and his stool was entirely bright red blood. We removed all collars and rushed him to the emergency vet clinic- closest one being almost 2 hours away from us. He was hospitalized over night and required 3 more back and forth trips and an extensive medication regimen before he was finally on the mend.

Speaking to the emergency veterinarian she could not 100% say that the collar caused the condition, as the condition itself is still largely unknown and seems to have many triggers. However she said allergies and allergic reactions have caused or triggered gastroenteritis before. Other causes can be parasitic infections, food allergies/intolerance, infections, certain viruses and exposure to certain chemicals. So while they could not 100% confirm the collar contributed to his health emergency they could not 100% rule it out either. He did not have parasites, any food changes or viruses at the time of his admittance. After a steep 2k vet bill and money for gas back and forth my dog thankfully seemed to make a full recovery and is doing well.

My other dog expirenced some thinning fur on her neck but no sores or other health conditions. My moms other dog, a terrier, expirenced very red, painful and inflamed skin. He itched himself relentlessly but thankfully did not develop sores. Although he did seem to have a brief rash along his stomach and legs. This rash resolved shortly after removing his collar and routinely applying dog safe rash cream.

In addition to the multiple allergic reactions and possibly related health emergency, the collars did not seem to work after a week. The dogs would come in from a walk or playing outside and we'd find several live fleas on them a piece. We live in an area where fleas have been horrible this year but its like after an initial week of success the fleas were suddenly immune to these collars. If you already have a flea infestation these collars will do nothing for you, they barely worked for prevention purposes alone.

Over all, I urge anyone looking into using these collars to either try a different product all together or keep an extremely close eye on your pets and observe for an allergic reaction. I know every pet is different and every pet may have an allergy to a different flea med/preventative because they are essentially bug poison. But for a product meant to be used on animals we had way too many allergic reactions occur one right after the other and something is not right with either the entire product or at least the batch we received. During the time we used the collars we had no other changes happening that could have caused reactions. There were no food changes, all our animals were previously very healthy, only one animal (the Labrador) had a history of allergies and sensitive skin, there were no environmental changes, no new treats, no new shampoos/changes in bathing or anything else we could think of that would contribute to these reactions.

In addition, the timing of my dogs sudden health emergency was extremely suspect. I can't with 100% confidence solely blame the collar, but I find it strange that a year old puppy with no parasites or pre existing health concerns or exposure to toxic substances would suddenly, in a matter of days, decline to the point of requiring a hospitalization.

My family and I have unsubscribed and will personally not be using this brand of flea control again. It was a miserable, and very expensive, expirence for us and our pets that in the end did absolutely nothing to prevent or kill fleas.

Please be very careful if you choose to use this product and monitor your pet very carefully in case they too expirence an allergic reaction or other health condition.
