I gave both of my dogs Nexgard yesterday. Within hours, my little Shih Tzu had horrible diarrhea. She has never had this before and she is 13. This has continued, unabated, for 36 hours. I held food and pushed water. She now has nothing but blood coming out. It is absolutely horrible for her. I will say that her spirits are still high, and she has no neurological issues. The blood is abating as time goes by. I called her vet who advised me to hold food and push water. I think Nexguard did this to her as she has never had anything even close to this before. Be careful everyone. I will not be giving anymore internal flea meds to either of my dogs. Say a prayer for little Mia, please. Thank you.

We moved into a new house and there were fleas in the carpet. I purchased Nexguard from City Farmers for over $60. The " chewable" tablet crumbled everywhere when I opened it. The next 2 days my dog wouldnt eat or drink or move from his bed. His heart was racing and he was shallow breathing. I do not recommend this product. One week later and my dog still has fleas.

Opened a box of 3 that wash purchased from the vet, only to find 1 chewable in package. Perfectly sealed box. After reading reviews and the fact i can't even give both my dogs one each.

Perfectly healthy 8 month old puppy, running around happy in the morning, had the nextguard at midday. Horrible horrible diarrhea for the next 48 hours, he was dehydrated, and lethargic. Passed loose watery stools every hour for the first 12 hours, then every 2-3 hours for the next 24hours. No sleep for puppy or owner. Very scary. Would NOT recommend. This was his third dose. Have since ceased using this product.

Within 2 weeks after giving my schauezner she started throwing up, having seizures, not eating..Very lethargic, and spotting blood..This dog was completely healthy until i gave her nextgard...Im very scared Im going lose her..Its totally poisoned her

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

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.
Protect your babies.
Do not use this poison!!!!

Since using Nexgard my border collie is having difficulties with her hind legs & has starting falling over.
I wish I had read these comments prior to use.
Please do not give this to your precious babies

My stupid vet gave my Aussie who’s 8 months one chewy tablet last Thursday and in less than 24 she started vomiting and lathargic. This is pure poison please do not allow your vet to give to your pets.

My dog suffered notable hives, and vomiting, 5 months after her first chew, so after 5 chews. I changed her diet. My vet said Nexgard chewables were safer, less toxic than the topical. Therefore, I didn't consider them the problem. I reduced her dose to every other month to be cautious. When hives and vomiting returned, w/a strange cough, I ceased using Nexgard. It was too late. She had developed an inoperable heart tumor, after 7 chews, or 9 months. She died 2 months after diagnosis from heart failure, caused by the rapidly growing tumor. Flea and tick medication is for topical use only.

I don’t know why everyone is complaining. All flea and tick treatments are poison, because they kill fleas and ticks. My dog is 11kg and has no problem eating these, and has no reaction. There is a possibility of a bad reaction with any medication, so why this one is getting so much slack, I don’t know. But it works perfectly for my dog

15 days after his dose of NexGard, my beautiful two-and-a-half-year-old border collie had a seizure and 9 days later he had a cluster of five, cost us $700 to take him to the emergency hospital, where they put on anti-seizure medicine, and pretty much told us he would be on at the rest of his life. Hopefully, that won't be the case he had a slight seizure the day after the hospital visit, and I took him to our veterinarian who believes, as well as I do, that he was poisoned by NexGard. This stuff should be banned! And just because a dog is fine on it for a month or two doesn't mean it's not going she caused horrible at first effects.

Bought this to try as an alternative to topical treatment but it made my dog very sick with repeated vomiting
Returned rest of pack to vet for refund and they said this was common

I only treat my 17 month old Border Collie with a NexGard chewable during the tick & flea season. When I give him this product he has diarrhea for about 2 weeks before it clears up - 2 weeks before he is due for another tablet & another cycle of diarrhea. I know this problem is related to the drug as it does not occur during winter when he is not being treated.

Having read a lot of the reviews it appears there is overwhelming evidence that this product has not been through enough stringent testing.

Gave our 2 pugs Nexgaurd in the afternoon, by 9 our dogs had Diarreha and vomiting. Today one of Pugs is barely waking and very shakey. Not worth it. Absolutely disgusted my local Pet Market has recommended this.

Gave my dog this medicine after my vet no longer sold his normal flea pill which was comfortis and shortly after he had 5 seizures. Horrible! Will never give again.

The day I gave my two dogs a pill for their size, they have not stopped having diarrhea and vomiting. It’s been two and a half weeks, and nothing has changed. My dogs don’t even have fleas! The vet insisted I get this pill. They are losing weight and they aren’t as active anymore. I don’t know what to do at this point.
