Horrible side effects and death
I had been using comfortis, my vet stopped carrying it and heavily pushed nexgard instead. Said she was giving her dogs nexgard. I tried it on all 4 of my dogs, made one of them sick with diarrhea and vomiting and seizures. Two days later she’s dead and the vet can’t give me a definite cause. I know it was the medicine. She had a horrible reaction to it, so I can’t in good conscience recommend it to anyone else.

Don't use Nextguard, it's poison.
My Heeler was perfectly healthy. Vet recommend this (I didn't ask for anything) so I assumed it was safe. She got severe itching, hair loss starting on the ears. Then started vomiting, diarrhea, no appetite, very lethargic. Then vomiting blood. Narrowed all possible causes was after ingesting this poison. Warning:. You may kill your pet if you give it to them. Not sure if my girl will recover. Vet don't know what caused it, says it could be the Nextguard but can't say for sure but I know what happened to my dog. Nextguard was slowly poisoning her. I so regret giving it to her.

NexGard kills pets
I gave the nexgard 2-4 kg pill to 3 puppies. They are huskies. I thought that it will work for them since they had a bid of fleas. It was suppose to be a "safe" product. My puppies started feeling ill and had diarrhea they also started vomiting. I went to see the vet and first thought it was just a tummy bug or something. They did some tests and turns out nexgard poisoned my babies. The one puppy died this morning.
He had diarrhea, he vomited a lot, and he was very weak, he almost had no blood sugar levels. It was extremely traumatizing . One...

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.

These reviews are a little ridiculous, I give this to my Luna and it works amazing. No fleas No ticks just as it should be. No reactions she enjoy eating it, she thinks it’s a treat so it must taste good. I really don’t know what you people think all dogs and humans have reactions to certain medications, some just don’t mix well with others, some get side effects on ANY medication dog, cat, human. And your all saying it’s “poison” well it is killing fleas and ticks anything that is killing fleas and ticks is poison. Didn’t your vet warn you of ...the potential side effects? Did you read the paper in the box with the side effects on it? There’s one with every prescription. I have a positive experience and so does my Luna who isn’t getting serious tick diseases or scratching till she bleeds because of fleas.

Dog acting funny and lifting hind legs
Give my dog nexgard chewable yesterday. this evening while eating he was lifting his backs legs one at time a time. Very strange. His gate/stride has changed. I'm so scared I poisoned him with this medicine. Will this wear off? I just lost my senior furbaby and so afraid a gave my little guy something that will damage his quality of life or kill him. :-( What do I do???

I wish I could give it 0 stars!
I'm stating actual facts when I say I gave my Boston Terrier of 8 years of age and healthy, a Nexgard chewable she was put to sleep because of uncontrollable seizures. She started foaming from the mouth, then started to have a couple seizures (she'd never had seizure ever) Took her to the vet after the second seizure. They started her on antiseizure meds. Almost immediately after the start of the first seizure, the seizures got worse to where she was having longer and she was starting to not be able to get her self free from the seizures. ...At that point the regular vet was useless and she needed a Emergency Veterinarian. She only lasted a short time there with all medications not helping her we could only keep her sedated. Our only option was to end her pain and suffering.

Do your research on carcinogens
My Great Dane Ulysses had been on Nexgard for a steady year round flea and tick treatment as we live on a farm. We were told he needed year round treatment as ticks can be present depending on the weather. Suddenly on May 1, 2019 he stopped eating and only drank water. He became progressively worse, and we called our Vet and took him in. He was given something for his stomach and taken home. He still continued to get worse and we called the Vet again and took him there. They took an x-ray and told us to leave him. They called back and tol...d us we had to take him to a Vet Hospital as he was getting worse. We did and spent half the night there. They gave us 5 different diagnosis's and we went home figuring they could treat him as they found a enlarged heart and would treat that. That morning we received a phone call from the Vet Hospital telling us it was not his heart but he had Lymphoma cancer. We went back to the Vet Hospital with his sister, a Blue American Pit Bull Terrier, he was excited to see her and her him. He tried to get up but he was took weak to stand. They stayed together for about 20 minutes and then we put Ginger his sister in the truck and came back to the Goodbye Room at the Vet Hospital, where we blessed him said our goodbye's and I held his head and kissed him goodbye and held his head and petted him and kissed him goodbye, that was on May 9. 2019 at 4:30 pm. What we didn't know was that this had been building up in him the whole time. We did research and found that 1 dose of Nexgard can last in your animal for up to 12 months, and Afoxolaner is a carcinogen which can cause cancer in dogs. Ulysses was only 4 years old, and 175 pounds far to young to pass on this way.

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 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 i...mmediately 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.

My 4 months old puppy is having a neurological reaction!!!
My vet recommended Nexgard for a preventative for my 4 months old American Bully mix. After a few days I started noticing he was really clumsy. He went into his kennel and started trying to catch his balance and was stumbling over his toy. He finally fell on his side. It was super bizarre to me. After that I noticed he was having horrible diarrhea. His hind legs are super weak he’s having a hard time getting into a standing position. He’s been hiding in my room, laying down all day long. I can hardly get him to stand up and walk. He keeps tilti...ng his head to one side. He walks like he’s drunk and staggers around. It’s extremely scary to see him acting this way. He was a totally normal energetic puppy running and playing just a week and a half ago. To now extremely lethargic. Luckily he still has some spunk in him and wants to play when he sees another dog. But he just falls over. He still has his appetite and will gobble down his food. So I’m hopeful that he will recover. I have an appointment with the vet tomorrow morning. I’ll update when I can.

Works great, never had a problem with fleas or ticks and it's easy to get dogs to eat, because I guess it must taste good. Only product I use now
Nexgard killed my dog
I had a normal healthy dog until I switched to nexgard last spring. He went downhill from there & passed away in Dec. He turned into a dog I didn’t know. Seizures, mean to the point he bit me, constant pain.
