Small Dog Vet-Recommended Flea & Tick Treatment & Prevention Collar for Dogs Under 18 lbs. | 8 Months Protection

I've been using seresto collars on my dogs for years and have never had a problem with fleas or ticks. I have a dog that has seizures and this is the only thing he can use for flea prevention and it's much safer than the topical and pills. I usually get at least 8 months use out of each collar so it's well worth the price. I have small yorkies and I can cut one collar in half and sew it onto a regular dog collar and that saves me a lot of money and there's no issues at all with it working any less. I basically get two for the price of one. My dogs have never had any kind of skin irritation or problems with this collar

I live at Ground Zero for all kinds of ticks (Cape Cod, MA) and the spring can be a nightmare if you have an unprotected dog. My dog takes a once-a-month oral flea, tick and worming med but she still gets ticks without this collar. According to her vets, the Seresto collar and the oral med work via different physiological systems of the body and they say you can use both, together, without hurting the dog. This is the 4th tick season I have added this collar without any problem and it DOES work better than any tick preventive I’ve used (I’ve had dogs my whole life). The only thing I would advise is that you put the collar on the dog as per the instructions but do so 2 weeks before you think you need it because it seems to take that long to maximize it’s effectiveness. If you have any concerns, talk to your vet.

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!

My dog is very sensitive and I cannot use the flea and tick drops on him. Even other flea collars would cause him to be lethargic and feeling ill. My vet recommended this brand and it has been perfect for keeping the fleas away while not making him sick. He is a Yorkie.

Works pretty good but we still see fleas crawling on our dog. However, I think they don't bit her as much or reproduce much.

Have used Seresto collar for the past few years but this time my little dog has more ticks than he's ever had. Very disappointed after paying a premium price!! Guess this will be the last time I purchase and/or recommend Seresto. You lost a long time customer

I’m on my third year purchasing these collars from Amazon for my mini labradoodles and highly recommend. We live on a 25+ acre property with woods and fields. Since using these I have not found ANY ticks on my pups, who are outside quite often. I replace them in April and October, and they last all 6 months. I do take them off for baths but that’s it. Zero complaints!

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.
