Seresto Reviews | The Complete Guide (Including Side Effects)


We did plenty of research before completing our review of Seresto Dog Collars. In particular, we wanted to make sure this is a safe product before recommending it to our readers.

We did find some anecdotal reports from some folks online about the safety of this product, however, we also found similar reports for other pesticide-based flea and tick control products.

OUR #1 PICK

Bayer Seresto Flea and Tick Collar

The best value for money

Seresto Collar

This harness gets our vote because of it's multi purpose use. It's made of quality material that provides extra support along the back (much needed for Dachhunds), as well as a handle that enables quick and safe lifting for any situation. The padded straps make it super comfortable, helping to avoid skin irritations.

Want to know the truth?

A small number of dogs can have hypersensitivity to certain chemicals, and pesticides are known to sometimes trigger extreme reactions.

Instead of deciding for you if Seresto Collars are safe, we tried to present some resources and information that you can trust so that you can make the right decision along with your vet for what is going to work best for you and your dog.

We did, however, find lots of confirming evidence from customers, veterinarians and independent research studies that the product is effective.

On this score, unless your particular geographic area has already developed resistance to this product, Seresto Flea and Tick Collars are very likely to be an effective way to treat fleas and ticks on your dog.

Seresto For Dogs | Why is Flea and Tick Treatment Important for my Dog?

Ticks

You may have heard of Lyme Disease or Rocky Mountain Spotted Fever. Depending on where you live, these tick-borne illnesses may even be common, particularly for people or dogs that spend significant amounts of time outdoors.

However, there are actually many tick borne diseases throughout the country, a full list of which you can find here.

It is untrue that there are areas in the United States that do not have ticks.

This distribution map published by the Centers for Disease Control and Prevention, shows that every state does have at least one species of tick.

However, some more specific environments, such as urban spaces, likely have less chance of encounters with ticks than thick woodsy environments where ticks are more common.


Fleas

Fleas are also vectors for a few nasty conditions that can affect your dog. Many canines are sensitive to their bite, causing scratching at the site of the bite and in some cases excessive licking and biting which can lead to “Hot Spots.”

These are patches where your dog has licked away the fur. They are painful for your dog and can also be persistent and difficult to treat.

Fleas can also carry tapeworms, a nasty parasite that can also spread to humans.

Although rare, fleas can also pass on “Cat Scratch Disease,” Bartonella, and Maurine Typhus, very serious diseases that pose a threat to human health.

Fleas also pose the potential threat of infesting your home.

Once established in carpets, furniture and bedding, fleas can be extremely difficult to irradiate, sometimes requiring professional extermination.

By properly treating your dog, you can prevent the primary means that fleas will enter your house, stopping them before they have a chance to take root.

Safety Precautions When Using Flea and Tick Dog Collars

  • Never combine flea and tick treatments since this can cause an overdose of medication
  • Never use products designed for cats on dogs, or vice versa
  • Always carefully follow the manufacturer’s instructions for use
  • Keep children from touching or playing with medicated collars
  • Wash your hands after fitting or touching the collar
  • Stop use immediately and call a vet if your dog shows any concerning symptoms

Are Seresto Collars Safe?

When we started our research for Seresto Collars, we did find reports from customers with safety concerns about this product. It is important to note that ALL products that use pesticides to kill fleas and ticks have similar customer complaints associated with them.

Anecdotal reports are hard to verify, may be related to something other than the product, and are not the same as scientific research on the safety of a product.

Note that for example, a very popular product, such as Seresto Collars, is going to be used by millions of dog owners.

Even if a tiny fraction of these owners have a problem, it is likely to show up on the internet.

Since it is impossible to assess the frequency of problems from such anecdotal reports, it is also impossible to call a product unsafe strictly on those accounts.

Still, we saw enough reports that we wanted to give our readers some resources to learn about potential problems with this product, so that you can talk to your vet and decide if this is the right product for flea and tick control.

If you decide it is, we have linked the two collars now available on the market so you can be sure to get it in the right size. Click HERE to jump to that review.

If you decide you want to try some other products to see if they provide flea and tick protection without the risk of pesticide-based formulas, click HERE to learn about some alternative products that may be what you are looking for.

Veterinarian Perspectives

In some cases, veterinarians have raised concerns about the safety of Seresto flea and tick collars, others have deemed the product safe.

Here are a few references to read if you are interested in the advice of some professional veterinarians:


National Pesticide Information Center

A helpful resource for dog owners, provided by a partnership between the EPA and Oregon State University is the National Pesticide Information Center.

This organization sponsors an information phone hotline for consumers to call and get the most up-to-date information on pesticides of all kinds, including topical flea and tick treatments used for domestic pets.

The helpline is available Monday – Friday, 8:00 AM – 12:00 PM, Pacific Time. The number is 1-800-858-7378.


Environmental Protection Agency (EPA)

The EPA released this report in 2016. Their conclusion is that Seresto collars are safe for pets wearing these flea and tick collars.

They do, however, recommend that children should not play with the collars, and should be quarantined from the pet during the first day that they are wearing the collar to minimize exposure to the child.

This report also mentions that the EPA has received reports of adverse effects in pets and promises further evaluation.

Interestingly, the EPA did evaluate another pesticide in 2014 that was used in flea and tick collars called, propoxur. They noted that there were unacceptable risks to children in the first day of application.

Sergeant's and Wellmark were the two companies that were selling these collars, and they subsequently voluntarily pulled them from the market.  


U.S. Food and Drug Administration

Although the regulation of topical flea and tick products is the jurisdiction of the EPA, there is also some general oversight provided by the FDA for these types of medications. You can find the Seresto registrations with the FDA here and here.

In addition, some helpful information on the use of external flea and tick products can be found here

Included in this document are important helpline numbers for reporting incidents of negative reactions from the use of these products.


Seresto Dog Collar Customer Reviews 

Seresto dog collar customer reviews on Amazon show that this is the most popular flea and tick collar on the market.

With nearly 10,000 customer reviews, the Seresto collar for large dogs gets a 3.9 star rating, with over 60% of customers giving it 5 stars.

Among the near 20% of customers that gave it one star, about half reported that the collar was ineffective. Note that sometimes fleas and ticks develop regional resistance to pesticides, which may account for some of these complaints.

The other half of the significant number of one-star reviews mentioned health problems and side effects from using this product.

Although rashes, lethargy and loss of appetite were the most common symptoms noted by unhappy customers, a few of the reviews documented extreme adverse reactions, including seizures and neurological problems.

At least 15 of the customer reviews sadly reported that their dog died shortly after use of this product.

To contrast this data with the next most popular flea and tick dog collar, the Hartz Ultra Guard Plus, only 34% of customers gave this collar a 5 star rating.

42% gave it a one-star rating. The reasons for negative reviews were overwhelmingly about ineffectiveness for flea and tick prevention.

Among the 104 one-star reviews, six customers complained the product made their dog sick, and none reported death.


Seresto Collar Side Effects

Unfortunately, the product label for these flea and tick collars does not include potential side effects. Bayer has also failed to be transparent about potential side effects on their website.

The instructional leaflet that comes with the product does mention “Slight hair loss and mild skin reactions due to the mechanical irritation of the collar may occur at the application site which usually recover within 1 or 2 weeks without the need for collar removal.”

The leaflet also warns to keep the collar out of the reach of children, and to not let them play with the collar.

However, we can learn more by looking at the active ingredients, flumethrin and Imidacloprid.

Symptoms of toxicity with Flumethrin:

  • Ataxia (loss of muscle coordination)
  • Hyperreactivity (behavioral changes)
  • Tremors
  • Skin tingling
  • Extreme lethargy
  • Drooling
  • Vomiting
  • Diarrhea
  • Incontinence

Symptoms of toxicity with Imidacloprid:

  • Rash
  • Fatigue
  • Twitching
  • Cramps
  • Muscle weakness
  • Difficulty breathing

Both of the active ingredients have raised environmental concerns about their impact on bees, birds and aquatic life.

If your dog starts showing any of these symptoms after using a Seresto collar or any other product containing pesticides, immediately take it off and wash your dog with a mild detergent and plenty of water.

Call your vet to talk and make an appointment so they can do a proper evaluation and diagnosis as well as recommend alternative treatments if necessary.


My Dog Ate a Seresto Collar!

If you suspect your dog has eaten all or part of a Seresto or any other medicated flea and tick collar, take them to the veterinarian right away.

If your vet is unavailable due to a holiday, call the APSCA Poison Control Center Hotline at (888) 426-4435.

All Flea and Tick Pesticides Can Trigger Potentially Severe Symptoms

Some veterinarians have pointed out that there are potential adverse side effects with all pesticide-based medications used for flea and tick prevention including collars, drops, pills, shampoos and sprays.

For example, Dr. Deva Khalsa points out that the active ingredients in several flea and tick treatments have been implicated in a variety of health problems, including thyroid cancer, kidney toxicity, nervous system issues, extreme lethargy and seizures.

It is critical to work with your vet to find the right product for you and your dog.

Since flea and tick-borne illness are also potentially deadly to your dog, you will need to weigh the risks and benefits with your veterinarian.

Do Seresto Collars Work?

With the exception of some regions where fleas and ticks may be resistant to the active ingredients, there is plenty of evidence to suggest Seresto collars provide an effective treatment for these external parasites.

Your veterinarian can confirm if the product is working well in your area.

  • When compared to other flea and tick collars by average customer reviews, Seresto collars seem to be significantly more effective than other dog collars on the market that we reviewed.
  • As we indicated above in our summary of customer reviews, the vast majority of customers of this extremely popular flea and tick collar for dogs rated Seresto collars as effective to very effective.
  • Independent research studies have also confirmed that Seresto collars provide effective treatment for fleas and ticks. See (Stanneck et al., 2012) and (Brianti et al., 2013) for more information.

  • For dogs weighing over 18 pounds

After thoroughly reviewing as many products as we could find, Wiley Pup did not identify any all-natural flea and tick collars that seemed to work well enough to recommend to our readers.

However, we did find several all-natural flea and tick preventatives for dogs that do have a good track record.


Pest Peeve – Pet Fleas Are History – Flea and Tick Powder

Pet Fleas Are History

This all-natural product works two ways. First, the tiny sharp edges of ground diatomaceous earth is both irritating and deadly to small insects because it is small enough to shred the delicate exoskeleton of bugs.

Second, both Neem and Yarrow Flower have insect repelling qualities.

In addition, this all-around product can also be used for bedding, carpets and even outdoor applications. It is eco-friendly as well.

  • Neem Leaf Powder – 25%

Wondercide Flea and Tick and Mosquito Control Spray for Cats, Dogs and Home

Vet-Kem Ovitrol Plus

It both kills and repels so you can rely on this product to quickly reduce an infestation in your home. This responsibly sourced and eco-friendly product gets high reviews for effectiveness and one of the most popular products in it’s class

Conclusion

At WileyPup, we want you to have the information that you need to make an informed decision about the products and gear that you choose for your dog.

While some consumers have had negative experiences with the product, the vast majority report a safe and effective experience with Seresto dog collars.

Just in case you decide it is not the product for you and your dog, we wanted you to have some viable alternatives, including flea and tick collars that use other pesticide ingredients as well as some all natural flea and tick control alternatives that some of our readers may find most appropriate for their needs.

Thank you so much for the research! It is very hard to find information like this on flea products without having to spend hours researching it online myself. Of course, I still did a little research before I found this site, but everything here confirms what I have read elsewhere. I still am extremely torn between purchasing a Seresto collar for our pets, mainly because of the chemicals. But we have the worst flea infestation ever, so I might just need to use them for a few months and then use the more natural powders/sprays as an ongoing preventative one the house is flea free.

    Hi Elizabeth,

    Thanks very much for the nice comment. I think your plan is fine, if you’re ever in complete doubt have a chat to your vet. If possible use the collar when your able to monitor your pets throughout the day.

I have found the Seresto tick a flea collar to be totally ineffective. We have a large dog (Golden) and are in Northern NY which is ripe with ticks. Since having the collar on for the last week and a half we have removed two live ticks. She does like to swim but according to Bayer the collar is still effective with swimming but the duration of coverage is reduced by a month or so. I understand that nothing is 100% effective but a tick a week is a bit much. If you haven’t purchased protection yet then steer away from this Bayer product. Its a waste on money.

    Hi Harold,

    Thanks for sharing your experience, there’s certainly a whole heap of mixed reviews. Had the ticks bitten your pup? Sometimes ticks will still end up on dogs (and other animals) however the tick repellant stops them from actually biting.

    Would be interesting for us all to know.

    Sorry to Lol, I’d be happy with a tick a week. Yesterday alone I gathered over 50 ticks, fat and sassy off my dog and my floor (thankfully I have concrete) and he isn’t due for Vectra 3D until next week. Hence the reason I’m searching out something else.

Several months ago, I was at Petco and looking at the different flea and tick medicines for my animals, and was basically talked into Seresto collars. I have 4 dogs, two large and two small, plus I have 2 cats, so I purchased the Seresto collars for all of them, costing nearly $400.00 at Petco. Well, these collars are a huge waste of money, as my own animals are all itching, so they are not working on them now. Last summer (2017), I purchased the Seresto collars for my dogs, and they seem to have helped them tremendously, but not this year. I am not sure what the return policy is at Petco, but I wanted to give it some time to work, so it’s been over the normal 30 days. Is there anything you can offer as returning them seems to be my only option? Hope to hear from someone at Seresto. Thanks much

    Did the same thing this year. Bought the Seresto colors for my two large dogs and seven cats. Worked liked magic last year (2017). My poor little babies are still scratching and I’m pulling fleas off every day. Spent about $400…. Not sure in going to do it next year. We live in TN.

I bought the Seresto collar because I found more than 10 ticks on my dog after going for a hike. At the time my dog was on FirstShield Trio. The Seresto collar had been effective for 3 months until yesterday when I found that my dog was crawling with fleas. That’s right. He’s still wearing the collar and it’s only 3 months. The collar has had minimal exposure to water and was still applied correctly. I came to this website to try to find answers about the collar before going out to buy insecticides to treat my home.

I recently read that the Lyme vaccine for dogs is not as effective as I thought it was. My dog would get a Lyme booster every year after the first 2 step vaccination. Both the vet & vet tech said that they don’t vaccinate their dogs with the Lyme vaccine due to its lack of effectiveness. I decided not to give my dog a booster this year, opting to get a Seresto collar instead.

I applied the collar to my smooth collie, and within 24 hours she was having neurological side effects, explosive diarrhea & sever lethargy. She started trembling & acting strange. She wouldn’t eat anything. I removed the collar in the late morning, gave her a thorough bath with Dawn dish detergent (2 good lathers) and a last lather with Dr. Bronner’s lavender soap. I let her air dry. By evening, she was a bit more lively, but still had bad diarrhea. I finally got her to eat some boiled chicken. Last night, she woke me up 3 times because she had diarrhea. She didn’t eat breakfast, and I made boiled chicken & plain white rice, which she ate. She still has diarrhea, but is not exhibiting the neurological symptoms anymore. Hopefully, the diarrhea will stop when the chemicals are totally out of her body.

Herding dogs are much more sensitive to certain chemicals & I was very hesitant to try this collar on her for that very reason. I have heard good things about this collar–my neighbor’s dog wears one without any problem–but have also read the hundreds of thousands of scary stories about it too. I guess I can add mine to the scary category. What this collar did in a matter of 24 hours to a smooth collie with very thick neck fur is mind boggling.

So, I will keep rubbing lavender oil on her before we take our evening walks, be vigilant with insect control on my lawn & keep planting lavender, lemongrass, lemon thyme, basil & peppermint all around my property to keep bugs away.

    Oh my that’s terrible! We just removed the collar of our lab/retriever mix 5 1/2 yr old boy. He’s not had diarrhea but had a hug raw wound and is very lethargic. We’re taking him in tomorrow since he’s able to eat and no problems with urine output or bms. These side effects are after 4-5 days of it being off and a bath. This is a terrible thing to sell for pets.

My Brussell Griffon wore the Seresto collar less than two months. We cut it off her and threw it away because out of the blue she became blind. The vet has no explanation and sent us to an ophthalmologist. The visit was inconclusive but he was 90% sure she had SARDS.
I believe the collar had something to do with this. The vet says no, but they sold us the collar.
My husband and i now are second guessing ever using that collar. It has been 5 months and our hearts ache every day watching and wondering if we caused this. Use this collar with CARE- i would never use it again.

Hi there…. I was wondering…. did you ever do bravecto reviews? I was hoping that you may have. My two dogs died within a month of administering that product and they went under 3 weeks apart….both lost half of their body weight 4 lbs to 2 lbs and 28 lbs to 16 lbs. I found out that the FDA shot it down for humans (spraying on crops) and that a group of wealthy individuals picked it up and tested it on beagles. they passed and so it went out to them and cats. Over 41K dogs that I knew of at the time back in June, died from this. I contacted an atty and the only thing he said was that we needed to show causation. I really wanted justice for all of those people who lost part of their family. I was hoping (and still hope) to do a class action. It makes me sick. What can you tell me? thank you…………………………….debbie

Purchased seresto for my lab/retriever mix boy aged 5 1/2 yrs. I was happy to use this for a few reasons being it had good ratings and was economical. Applied collar mid July and by mid September he was oozing under his neck from a patch that all the hair was missing. We first thought he had an ear infection and was going to apply drops but we noticed his ears were perfect. Then the ugly raw wound under his neck was revealed. Oh my I almost got sick and knowing my boy was this ill I still can’t get over the guilt. So all of this was happening when hurricane florence was almost going to hit us here in southeast Virginia. I was trying to remember any side effects since we started this collar and the only thing I remember was what I thought was a runny nose. He is a lover of sniffing and sneezing so I chalked it up to that not realizing he was falling ill. During the entire time he would eat, be rambunctious and have normal urine and bm since starting this collar. It wasn’t until approximately the end of the two months being on this is when his lack of play and desire to greet us is when we noticed he’s not himself. And this is after the collars been off for 4-5days and a bath. He still will eat and have normal (no diarrhea) and urine output. He’s eating but not so happy to do so. He usually runs when he hears the food hit the bowl. So I’m my mind the many customers that have given this product it’s glowing reviews may not be after a while like we did. The company we purchased from gave us a refund and will alert Bayer about this. Unfortunately I discarded the wrapper and tin container it came in. He will be seen by our tomorrow morning.

My beautiful, very beloved cockapoo, Chewie, was lost to us 6 wks ago due to cancer of the lymph nodes and blindness. He had been wearing the Seresto collar for 2 yrs, and had been experiencing diarrea and vomiting for quite some time. We tried many different kinds of foods thinking it could be his diet causing these problems. He was on allergy medications as his skin was always irritated, dry and sensitive. Now I’ve been reading reports of dogs dying of lymphonic cancer who wore Seresto collars. My heart is broken first of making the decision to put him down and now the thought that we caused this cancer because of putting this collar on him. My pain without him is never ending. Your comment on this devastating unnecessary loss to me?

Hi there I wanted to comment on that I have a rough collie puppy, eight months old. Have been using the soresto and not happy with it as well. I purchased mine as well around May 2018. As you can’t get it in Canada. When it went through the border okay. I bought another 2 to have a good supply around the same time. I had heard really good things about this product as to less side affects. As my concern was all my other dogs were on advantage and all had developed seizures as they grew older, so we switched products to see if this would be better. Not saying advantix was the problem. Just process of elimination. Now I am wondering which is the lesser evil as I just pulled off another deer tick off of him today. So really scared. Wondering if like other responders we have a bad batch as well. It would cost me more to return the products than its worth. What is a good alternative?

I put the Seresto collar on my dog Nov., 7th, 2018. She has been vomiting and having extreme thirst. Took the collar off her early this morning and plan a bath to see if she improves. It seems reasonable that any product that is toxic enough to kill & repel fleas and ticks could also have dangerous side effects. The previous collar was effective for about 6 months.

Always purchase these collars at an authorized retailer online or in store. Several websites are offering them for 30 to 35 dollars. These are FAKES! I was ripped off. You cant really buy these collars that cheap. Fake collars smell kinda like lemongrass and look totally different than the authentic ones. The real ones always come in a can sealed in bag with numbers printed on it and reflectors to add to collar. If you bought a counterfeit collar take it off your pet now.

So far no problems from my 2 Yorkies after 2 weeks.
