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.

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!

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 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.

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.

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.

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.

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.

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 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.
I have stopped giving this to my dog!
I haven't had a dog for a while and was told by the local pet shop that Nexgard was a good product. I noticed every time after I gave it to my dog she would vomit and scratch her skin and ears for days. I decided to do some research as I had a gut feeling that it was the Nexgard. After researching Nexgard on the internet I found hundreds of people in the same boat with their dogs having reactions to the product. I have stopped using the product.
Doesn't Work - My Dog Still Got a Tick Born Disease
My dog has been on this flea and tick treatment since a puppy (October 2018) and was recommended by my vet at his first puppy visit. I assumed it was doing the trick as I did not see fleas or ticks on him so I continued to use it for the last year and have NEVER MISSED A DOSE (NOT EVEN BY A DAY). My dog just had is one-year exam at the vets and after getting his bloodwork back they determined that he has Anaplasmosis (a tickborne disease). I spent hundreds of dollars buying this preventative only for it to not work. Not worth the money in my opinion as I still spent hundreds of dollars treating the Anaplasmosis.
Not working, my dog got lyme disease
My dog (a husky)was using nextgard she got bitten by a tick and got lyme disease. I spent $1000 dollars in blood works antibiotic and she may have to deal with the lyme for the rest of her life. She is just 6 and she was limping because of lyme.
When I call them to ask for the guarantee they offer me to replace the 6 pills or give me the money I spent for the pills. They know this product doesn't work, they said over the phone that a dog can get infections from the ticks in the 48 hours that it takes for the quimic product to kill the tick.
Do not waste your money, buy any other product.
Oral Pesticides are Poison
Our beautiful 7 1/2 year old boxer, Sophie, had to be euthanized yesterday after suffering from a series of grand mal seizures as a direct result of Nexgard. It was a prolonged, catastrophic neurological event that went on throughout the day and night (even with a continuous IV of anti-seizure medicines). She was blind, lame and barely responsive at the end (20 hours later). She weighed 60 pounds and took the NexGard dose for dogs 60 - 125 pounds approximately 45 minutes before the seizures began. I will never forgive myself for giving her a toxic oral pesticide and not doing my due diligence.
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.

Questions & Answers
Can the 60 lbs tablet harm a 48 lb dog
Our Standard Poodle doesn't like the NexGard chewable. He loves his HeartGard chewable. He will even sort it out of soft food after I break it into smaller pieces. Is there another flavor available? Any other ideas?
Can a overdose of nex gard cause paralysis of back legs and constipation.? It's been 10 days and he is barely walking and not going to the bathroom. Please help me. I only blame myself for giving him too much. Heartbreaking and hate myself.
I am no veterinarian or expert, but I have read dogs having similar symptoms from Nexgard. All flea treatments have chemicals in them that are potentially harmful to your animal. I opt for natural solutions, although not as effective and more work to maintain a flea free environment my dogs are not eating what I refer to as poison. I'm sorry to hear this has happened to your dog. Please see your veterinarian.
Irrespective of your statement about having given your dog "too much"??? These symptoms can also occur if your dog's been bitten by a mildly venomous snake such as a brown grass/tree snake or some of the whip snakes. It's quite common for such an attack not to show up in scans or x rays. One sign you will notice is if your dog frowns a lot as they get bad headaches from snake bite.
