NexGard Chewables Red (25.1-50kg)

Gave my 6 year old dog her first table ever. Had her forest seizure and then continued pretty much fortnightly for three years until she died from a brain bleed. Cluster seizures, emergency trips. Horrible. Medication Harley helped. Do not give your animals this poison Show details

I regret trying this on my dog. She has had side effects of hyperactivity/ neurological changes as a result that she never presented before. She has gone from being a great dog to being agitated, showing aggression and not listening to commands just days after her first dose. We are currently weaning her off of it. Show details

After 2 years of using product... my pet still got heart worm.... The best part is you have to buy the treatment from the company that you bought the medication from to protect your pet....

Works great!!! – My 2 year old Boxer was literally infested with eggs, ticks and fleas. They were groups of them on him and he would not allow me to touch him for longs periods of time. Neither frontline nor K9 advantix worked. I decided to try Nexgard. Within 24 hours they had all disappeared but 2 that were stuck in between his paws. The 2 I removed we're dead… Read more

and we're "dry". Would definitely recommend, I have not seen any negative signs, but always keep an eye on my pets to in case of side effects.

Can't live without it – My dog is very allergic to fleas. 1st day on this medicine and the fleas are gone. It is amazing!!! Can't say enough good things about it.

Go to flea and tick treatment – We moved to Nexgard after having issues with another brand. I had read reviews and was hesitant to try it on our Greyhound and our Lab/retriever but as we needed a tick treatment as well as a flea treatment I decided to try the monthly chews. We have been very happy with this product and they dogs have not suffered any bad reactions.

Unable to administer – My dog refuses to eat this product no matter what I put on it or what I put it in. Even If I chop it up in fine pieces in his food, he then refuses to eat his food. There are two other dog owners in my neighborhood who also have issues with getting their dogs to eat Nexgard plus. Was this med not tested for taste and administration issues? Show details

Loss of my dog – My three year old boxer mix went to be spayed and she was also given next guard and she started acting differently she went from being a healthy active dog to being ill very fast she started vomiting and had real glaze eyes was going to take her to the vet to see what was happening but then she suddenly passed away , the spay went smooth and… Read more

there was no complications from the surgery her incision was clean and there was no signs of infection or any other problems from the surgery she didn't start getting sick until she got the nextguard my other dogs were given the next guard as well and they vomited all day but they made it through it but my boxer mixed sadly did not she passed away two days later after getting the medication for to get rid of the fleas that she was having an issue with my baby girl was the best she was healthy happy and playful

InEffective – Been using this for couple years, now Just left North Central WV animal hospital because our beloved 10.5 yr old pitbull (severely sick lethargic - tremors) - he tested positive for 3 tick borne illnesses including Lyme- he just had nexguard chewable 3 weeks ago- he has joint pain- weakness- lameness- dehydration- kidney failure - So I have been giving this to all 3 of my dogs- and now the other 2 will need blood tests tomorrow- Show details

Bad case of hives – After I gave our Labrador his first dose he became very anxious. The next day he was covered with hives. They were all over his body as well as in his mouth and his eyes. It was horrible and he was so miserable. We has to take him to our vet for an emergency appointment. They gave him a prednisone injection an also an injection to relax him. We really thought we were going to lose him after giving him NexGuard. Show details

Nexguard doesn't work – Doesn't repel doesn't kill eggs pupae or larva. JUNK. Avoid buying your pet will itch, which is why we buy flea pet meds. After I treated the environment and avoided other animals it began to take effect, but that was almost two weeks. Show details

So dodgy try anything else – Pretty much instantly my Golden retriever need to go out and do Diarrhea, He is 3 years old and has only ever done this once in his life. 4 days after his single dose and he has done it about 20 times. Will he ever have normal stools again? Wish i had read the hundreds of bad reviews for this product. I hope my review helps your beloved pet. Show details

Dog hates it – It’s supposed to be a delicious flavour that your dog will love….hahaha my dog absolutely hates it. Each month I get to struggle trying to give it to him by breaking it up and putting it in his food, and he eats around it before leaving its remnants in the bowl. This is a dog that eats anything FYI.

Caused life threading GI upset – The ticks in my area are very bad so when my vet suggested this for my 8 year old rottweiler, I happily agreed. Within 12 hours of the first dose, she had a brief bout of diarrhea. Then, 1-2 weeks later, more diarrhea with blood. I didn’t connect the dogs and gave her a second dose. Within 1 week of her second dose she had severe bloody diarrhea… Read more

and stopped eating. Shortly after that, she started vomiting and could not keep down more than 1-2tsp of food, and was very lethargic. After a 2-day stay at the veterinary hospital she is almost ready to come home, but I will never give this to my dog again. Before starting NexGard, she never had any health or GI problems.

Do not give your dogs NexGard – This drug for flea and tick has been pulled from the USA market due to adverse reactions. I have my greyhound just one of these and she had diarrhea (the worrying kind) and blood in her stools. I am off to the vet with her this morning (a new vet - who has said they do not recommend this drug to their customers). As opposed to my old vet who… Read more

pushes this as better than using flea and tick on the coat - more modern I was told. The reactions that some dogs can have are neurological in nature and also can eventually cause death. I stress - do not use this drug on your pets.

Nextgard killed my dog – This morning I found my dog dead after having given him a 1/3 chewable pill 3 days ago. Nextgard should be removed from the market. It's pure poison for dogs Show details

NexGard is Poison - Made My Dog Sick – My dog is a 6 year old female spayed pit bull brindle mix and she had always been a healthy dog. She has always taken Comfortis but at her annual check up recently her vet suggested that I give her NexGard to due an uptake in tick cases in our immediate area. After a week of giving my dog the NexGard pill she started breaking out in hives and her… Read more

left eye started to swell. I thought she may of ate something off the ground but than her condition worsened. She was vomiting every night and shaking like crazy. I took her to the Vet Emergency and $1800 later they couldn’t figure out what was causing her to have a fever and vomit. They gave her an ultrasound, X-ray, blood test and they couldn’t find nothing. I’m very fortunate that she still wants to eat but she is not drinking a lot of water. I have been feeding her boiled white chicken breast and white rice and I pour chicken broth and she seems to drink that. Taking her to the vet today to get checked out. Hoping for the best.

Our dog almost died & remains seriously ill after taking Nexgard – Our precious dog became seriously ill soon after taking one dose of Nexgard. We didn’t think he was going to survive & euthanasia was offered as an option because he didn’t seem to be responding to treatment. He's no longer in a critical condition, but remains seriously ill and we don't know what the future holds. Numerous tests are inconclusive… Read more

and we've been referred to a specialist centre. Our dog suffered many of the symptoms described here, and like many, soon after taking Nexgard.

Don’t allow those online "public statements" that appear to dismiss and even ridicule those speaking out, by labelling our experiences & concerns as "social media frenzy" - "anecdotal and unscientific” to discourage you from taking these reviews seriously. Diminishing these reviews as rare, cannot minimise the catastrophic consequences for those suffering a reaction. Nor are all the reactions as mild as they claim. I don’t have proof that Nexgard caused my dog's condition. But here are the indisputable facts. FACT:- Prior to Nexgard my dog was happy, appeared healthy, walking, normal stools, eating, drinking & playing. My dog is always at our side, he is not permitted to roam, is an indoor dog with a healthy diet & regular vet checks. Within 24hrs of taking Nexgard, my dog showed signs of lethargy, unstable and the first signs of diarrhoea. The diarrhoea increased to critically severe His bowel was filled with blood (ultrasound) He arched his back in sever pain He was panting heavily, drooling and his nose was dripping Vacant stare Disoriented & confused His eye developed an ulcer Small ulcers on his tongue. Became increasingly unsteady to the point where he could no longer stand and within 15 mins of making the emergency call he was barely conscious. Although I cannot say for certain that Nexgard almost killed my dog, I can say that his illness and unimaginable suffering after taking Nexgard is very similar to other dogs from this group. I would NEVER recommend Nexgard or any similar product. After our experience we feel that the claims that this product is safe would be like playing Russian Roulette, point a gun to his head and hope it’s the empty chamber. Granted the odds are one in thousands??? But we would NEVER EVER take that risk again.

My dog developed seizures – For 15 months we gave our Siberian Husky Nexguard Spectra on the advice of Jervis Bay Veterinary Clinic NSW Australiathe Seizures were so very terrible that “ Tzar “, is now on 100mg of Phenobarbital per day. We never used it again. He’s 3 in Jan 2021. And we now visit Bomaderry Veterinary Hospital in Bomaderry NSW Australia. He is now reduced… Read more

to 50mg per day for the last month. You need to pull your product from sale immediately. Seriously, I mean it . It’s toxic. And made my baby very very sick. You have cost us thousands of dollars and emotional pain. And I know it’s nextguard , Even the vet said it was most likely

Do not give to your dogs – My Cavalier days after giving him tick and flea nexgard started with severe diarrhea. After a few days took him to the vet ER vital signs were good. Thought perhaps backend was weak from so much diarrhea. He now can hardly walk. I will take him to our own vet ASAP. I sure hope he returns to normal. I am very afraid of all this! This should be taken off the market! Show details

Horrible – Franny is her name. She had no health issues till Nexgard was given. She was very lethargic at beginning for about six days, appetite was fine , then she started bumping into walls and objects in her path, took her to vet and then animal hospital where they found out she couldn’t see out if her right eye. Took her to an eye center where they ran… Read more

some tests in both eyes, concluding that she had lost vision on her right eye and had limited vision on left one, the test showed the eyes being fine though. Now she’s very depressed, peeing in the house and walking aimlessly all day. Next stop is the neurologist who agreed this medication is a POISON. We’re hoping for the best outcome but her health is declining rapidly

Dog had terrible anxiety and a seizure after NexGard – My 78 pound mixed breed dog had two doses of NexGard without a problem. The third time he had terrible anxiety for over a week and then had a grand mal seizure. Over time he has recovered. My other two dogs had no reaction. One out of three is not acceptable. Beware of this product. I'm still waiting for these chemicals to completely leave his system before my vet and I are sure he's ok. Show details

Dangerous product – My young Labrador did not want the chew. Had to mix it with treats and force him to eat it. Since then he has lost appetite, and losing hair from constant itching. Have read other reviews and shocked by the potential damage/death caused by Nexguard spectra. Dangerous product. Show details

Not effective for fleas – I have never had a flea problem like this with a topical flea control. I’m being bitten and have found a flea on me. My husband is being bitten and last week the woman who helps me clean was bitten. This product doesn’t work! Show details

Never use caused seizure to my dog stopped nexgard no more seizures – My 10 yr old akita had grand mal seizure from nexgard vet said it didn't cause seizure but now she can't take it anymore because she had seizure i threw 100.00 dollars worth of nexgard in garbage where this drug belongs my dog is seizure free since not using can't believe this drug is still available Show details

My dog had liver issues after taking this – on the very first day i gave it the dog stopped eating and then she was not active for days. She never was normal after that and she passed away after few months. Show details

Killed 2 of my dogs - avoid at all cost – I have owned Boxers for a combined 25 years with no neurological issues; until I administered NexGard. 6-months after taking NexGard they started having seizures which led to their passing. Show details

Warning; Don’t Trust This Product – I have been dealing with what I thought was food and or pollen allergies with my 18 month old Bernese mountain dog since she was *6 months old. I’ve modified her diet a number of times, yet the itching and periodic diarrhea continued to some degree. Over the past few months Mojo developed some skin sores from scratching and was recently put on… Read more

an antibiotic and steroid treatment, which seemed to help.

I was in Florida for the winter and was delayed 10 days from giving her the nexgard. As soon as we got home I gave her the monthly dose and immediately noticed the itching elevated, followed by diarrhea, lethargy, vomiting and unfocused stares. I realized this was her 3rd dose of the nexgard (RED). The vet increased her dosage based on her weight of 82 pounds and it’s been over this time frame that all her symptoms seem to have elevated.

A few days ago all the pieces fell into place, I realized that all the symptoms she’s had over the past year elevated within 3 days of taking this medication and the timeline was usually 2-5 days that the symptoms escalated. Some months were worse than others but all the symptoms were there, in varying forms. Another thing that is important to note is I’ve stayed in touch with her breeder and none of the other litter had these “food allergies”. I’ve since confirmed that 3 of the 5 puppies are NOT on nexgard but another flea treatment. (5th puppy is unknown).

Once I suspected the nexgard, I began researching and am horrified by how many folks have complained about this product, some even suspect it’s killed there pet!! The FDA has put out a few warnings, with the most recent on 9/2018. The more Ive research, the more horrified I’ve become.

I’m embarrassed that I did not make the connection of the nexgard before now, you can imagine how terrible it feels to know that I’ve been inadvertently poisoning my animal. :(

I do not do ‘reviews or comments” often but it is my sincere hope that I can save another poor animal and family member from going through this process. If you have a dog that is having ‘health issues’ and you’re giving them nexgard, consider the This May be the issue! What I’ve learned over the past few days is the active ingredient is a pesticide that goes into the animals bloodstream when the fleas/ticks bite, it kills them. How can a pesticide in the bloodstream NOT be harmful?! I trusted my vet and all the times I’ve taken her to him for her itching this was never a consideration? And I never thought to questioned that this (relatively) new product was safe.

* she been on nexgard since she was 4 months old, and I pray that the damage is not a lasting one. Stay tuned...and be aware of this product!

Dangerous product, do not use – Used Nexgard on my whippet. She had a terrible reaction. Became lethargic, wouldnt eat or drink. Took her to vet.. she had autoimmune. We have had to have her on medication, monitored carefully by the vet and it is SCARY!! Do not use this product. Research on line,, you will find many people who have similar stories about horrible reactions in their dogs. Show details

Total Poison – Used this product for about 7 months. It was great at killing fleas and ticks. Unfortunately it also killed my dog. What they don’t tell you is that the neurological chemicals that kill the fleas and ticks builds up in the dogs body resulting in a terrible neurological death for your pet. I gave it 1 star because 0 was not an option. Show details

I guess it works but i am worried – After reading these reviews I am worried about the cumulative effects this poison may have on my very healthy dog. We live in the #1 tick hotspot of Australia (Sydney's Northern Beaches), and we've already had a cat die due to paralysis tick, and nurtured another through (he's currently down again with 2nd tick of the season). My dog hasn't yet… Read more

had a tick on him, although he did transfer one to me one day. He wanders through the garden and has remained tick free all year. Is this due to the product? Or due to his breed - Rhodesian Ridgebacks are supposed to be more robust when it comes to ticks. Either way I am concerned about using this product non-stop so will halt using it at the end of summer. I also use homeopathic remedy in the water bowl of my pets (ixodes and ledum) which may or may not be helpful, but at least aren't poisons.
