What are NexGard Allergies?

NexGard is a flea and tick protection system that comes in a chewable pill for dogs. This tasty and soft chew has been approved by the FDA and is considered safe for dogs. The active ingredient, afoxolaner, has been proven to effectively treat and control ticks and fleas for one month, when given regularly. This item is from the makers of Frontline.

Although many dogs tolerate NexGard quite well, there are specific side effects that are listed on the label. When you are giving your dog NexGard, it is important to be familiar with the side effects that can occur. If your dog does have adverse effects to this medication, it is important to make an appointment with your veterinarian.

Many flea and tick treatments do come with warnings about side effects; however, it is important to give your dog some sort of flea and tick preventative to prevent Lyme disease and other conditions caused by flea and tick infestations on your dog and within your home. This is especially important if your dog goes outside on a regular basis and if you live in an environment where fleas and ticks are very common.

NexGard allergies in dogs occur when dogs have an allergic reaction, or suffer from side-effects, of this popular flea and tick treatment. The active ingredient, afoxolaner, may not agree with all dogs that ingest this oral preventative treatment.

Symptoms of NexGard Allergies in Dogs

Symptoms of an allergic reaction to NexGard will vary from dog to dog. Frequently diagnosed reactions to this flea and tick treatment include:

  • Dry and flaky skin
  • Loss of appetite
  • Vomiting
  • Diarrhea
  • Lack of energy 

Types

There are various types of active ingredients in flea and tick treatments. Types of active ingredients that are in preventative treatments include:

  • Pyrethrins
  • Pyrethroids
  • Etofenprox
  • Fipronil
  • Methoprene
  • Methylcarbamate
  • Imidacloprid
  • Amitraz
  • Selamectin
  • Nitenpyram

Causes of NexGard Allergies in Dogs

Causes of NexGard allergies in dogs are primarily due to the reaction from the active ingredient, afoxolaner. Specific causes include:

  • The hypersensitivity towards the main ingredient
  • An over-reactive immune system
  • Afoxolaner causing skin irritation to sensitive skin of the dog

Diagnosis of NexGard Allergies in Dogs

If you have recently started giving your dog NexGard, and he is showing signs of a reaction, it is important to stop giving him the preventative medication and contact your veterinarian. When you take your dog to the veterinarian’s office, take the package of this flea and tick preventative treatment in order to help the veterinarian come to a diagnosis. The veterinarian will take a closer look at the ingredients and asking questions pertaining to when his symptoms began.

To avoid a differential diagnosis, the veterinarian will perform various tests, such as blood work, urinalysis, and a biochemistry profile. Depending on your dog’s symptoms, your veterinarian may want to perform other assessments; however, this will depend on your dog and his symptoms.

If your dog has any skin irritation, the medical professional will take a closer look at his skin and determine if he needs to perform a skin test to be sure the irritation is a result of the NexGard. However, your veterinarian may decide to wait before a costly test is conducted; once your dog stops taking the NexGard, the symptoms may dissipate. It is important to understand that this may take more than one month since this flea and tick treatment is given once a month, and it may still be in his system for up to 30 days. Once your veterinarian suspects that your dog is allergic to NexGard, he will advise you to stop giving him the treatment and will recommend an alternative method, or more than one alternative, to help prevent fleas and ticks.

Treatment of NexGard Allergies in Dogs

Effective treatment of a NexGard allergy will be to stop administering this chewable pill to your dog. Other treatment methods that can help are:

Topical Medications

Applying a topical medication to your dog’s skin, if the reaction caused a skin irritation, will temporarily treat your dog. Topical medications may help your dog stop itching and licking his skin, and help his skin heal from this allergy.

Alternate Preventatives

Finding an alternate preventative for your dog’s flea and tick treatment may put an end to his allergies. You may want to research other alternatives, including holistic types, to keep your dog free of these parasites. Your medical professional can also suggest specific flea and tick treatments as well.

Recovery of NexGard Allergies in Dogs

If your dog is often outdoors it will be important to find something that works for him that does not include such harsh ingredients. Protecting your pet from fleas and ticks prevents more serious conditions from occurring, such as Lyme disease and other illnesses.

Once you find an alternative that works for your dog, it may take him some time to adjust. It will be important to monitor your dog’s skin and coat for any fleas and ticks to be sure the new preventative is working properly.

If your dog for some reason develops symptoms of allergies after you have removed the Nexgard chewables from his diet, contact your veterinarian. Your veterinarian may then decide to do further allergy testing to be sure of the ingredient he is specifically allergic to.

NexGard

Gave my 1 year old yorkie a nexgard chewable on Wednesday. Then , on Friday, he started vomiting (looked blood tinged) . He was not lethargic and drank plenty of water. By Saturday, the vomiting subsided but he started to have diarrhea. I was wondering if the nexgard can be the cause ? He doesn’t go outside. Could he have a virus? As I mentioned, though, he had no contact with outside or other dogs.
Thank you

Some dogs may have a reaction to NexGard (afoxolaner), vomiting with or without blood is the most common adverse reaction in the controlled study group submitted by the manufacturer with 4.1% of dogs taking NexGard showing that reaction. You should keep an eye on Mishka for any other symptoms and ensure that she is hydrated, I’ve linked to the prescribing information below which gives details on the adverse reactions for this product.

There are various causes for shedding hair which may or may not be connected to the NexGard and HeartGard; hormonal conditions, medication side effects, environment, allergies, parasites, infections among other causes may lead to a loss of hair. You should visit your Veterinarian for a general examination and a check of thyroid and other parameters. Regards Dr Callum Turner DVM

Dr. Callum Turner, DVM
1808 Recommendations
Any effects from the NexGard or the vaccination will pass with time; stress of the journey to your Veterinarian or effects from the NexGard/vaccination will last only a day or so (may be long if the NexGard is the cause). Just keep an eye on Carolina and ensure that she is remaining hydrated, there is little to do in these situations apart from riding it out; if the vomiting or diarrhoea gets worse visit your Veterinarian. Regards Dr Callum Turner DVM

I believe Nexgard killed my dog. The vet pushed the sale of Nexgard on me at an appointment. I gave it to my dog and roughly a month later she died, yesterday. She hadn't been eating much a couple weeks after giving her the medication and then she had non-stop vomiting and diarrhea. Visible side-effects didn't occur right away but rather over the following weeks.

Hi. We gave our boxer, Lucy, the chewable Nexgard for the first time yesterday. Within a few hours afterward, she started to become ill- rapid breathing, heart rate, bloated, throat/gut issues- vomiting, loss of appetite- very thirsty. Our vet suggested 75mg/6 hrs of benedryl- she's 72 pounds. The benedryl- seems to help, but it's quite noticable when the benedryl starts to wear off. If this is a monthly dose and she's having a reaction, is she still safe from fleas and ticks and how long will this recipe last?

Callum Turner
Dr. Callum Turner, DVM
1808 Recommendations

Given Lucy’s reaction to her first dose of Nexgard, I wouldn’t recommend continuing next month; there are many different flea and tick control products which are effective, I personally prefer spot-on treatments and have encountered less trouble with them. Benadryl may be given to Lucy two or three times per day at a dose of 75mg (dosage is around 1mg/lb). Regards Dr Callum Turner DVM

Dogs (like humans) can develop an allergy to something which they have been in contact with for a long time; with NexGard, it is a case of waiting out the effects of the NexGard (if NexGard is the problem, could be another allergy - have you used any new cleaning products or detergents?). You could try giving Willie Benadryl at a dose of 1mg/lb to see if there is a reduction in symptoms; if the symptoms worsen, visit your Veterinarian. Regards Dr Callum Turner DVM

Has Symptoms

Lethargy

Diarrhea
Vomiting
rabid breathing


My 11 pound mini dachshund Peanut took her first and last dose of Nexgard on May 17. By June 4th she was dead. She had no prior medical issues. She was 9 years old. She started vomiting and diarrhea the night she took the first dose. She made it through the weekend but required a vet visit Tuesday May 22 due to chronic gastro upset and not eating and lethargy. My vet called the Nexgard adverse reaction line and was advised to test for Addisons. Peanut got a shot to stop the vomiting. She had lost 1.5 pounds and was not eating. Her breathing was rapid and her heart rate low. Other than that all blood work came back fine including no Addisons. We went home with AD food to encourage her to eat. She would only eat very little. Her breathing became worse—more labored and shallow. She made it through the weekend but ended up back at the vet on Tuesday June 30 (Monday was a holiday). My vet sent us to an Emergancy vet as her breathing was so bad. She was hospitalized for 3 days and treated for aspiration pneumonia. Treatment did not work and she was sent home and started treatment for Valley Fever. She was also given prednisone for inflammation. No improvement was seen and we ended up at the emergency hospital on Sunday June 4. They gave her oxygen and 2 shots to reduce inflammation and a bronchial dilator. None of which worked and she had to be put down. The Valley Fever test came back the next day as negative. All 3 vets that examined Peanut were perplexed by her symptoms. My first vet said she is presenting as if poisoned. The bloodwork never revealed anything amiss. The final verdict was maybe it was lung cancer but it was not presenting like lung cancer. 3 weeks after being dosed she is dead. Is this a terrible coincidence? Not any of my vets can believe she is gone. It happened so quickly. She lost 4 pounds in the process and had blue tongue and gums by the end. We put her out of her suffering before seizures could start. Again is this all just a coincidence? I joined a Facebook group called Does Nexgard Kill Dogs? I don’t know but whatever happened seems to be linked. Even if she didn't die from it "directly" it made whatever she had clinical all of a sudden. Peanut died 3 weeks after I gave it to her. Their reaction line said she needed a blood test to test for Addisons because some dogs with that have a bad reaction. She didn't have Addisons. So much vomiting from the drug did cause her to aspirate vomit into her lungs. Vomiting, anorexia and diarrhea, lethargy and seizures are some of the reactions. She had all of them but seizures. She also didn't react with intense itching. It has perplexed 3 vets that tried to help her. I might be wrong but it seems a strange coincidence. Plus the group above has story after story of dogs passing from this drug/neurotoxin. I am just a lay person but I feel like I poisoned my dog and hastened or caused her death.

There is a lot of controversy surrounding NexGard (afoxolaner) with many groups on social media spreading the ‘horrors’ they experienced using this product; from a professional point of view I am only able to reference reputable sources in my responses. Out of all the information online surrounding NexGard, the reputable sources all quote that no adverse reactions were reported during the US field study. I cannot confirm or rule out NexGard’s involvement in Peanut’s death, a thorough necropsy by a board certified pathologist may yield some information. Regards Dr Callum Turner DVM

Also important to note, like police when they kill Innocents, you guys "investigate" yourselves so to speak. And just like them, you not -so-curiously don't find anything wrong...

So all the people who had their loved ones die after taking this drug is only coincidental? Your not a professional, you're a capitalist drug dealer. I'd call all the people's bad experience evidence, but I'm just some crackpot conspiracy theorist because I question the status quo. Fortunately for you, America is love with spreading the greater israel project, and society is controlled by their need of disinfomation and greed. I personally would rather trust some holistic witch doctor with voodoo doll than to have another dog killed by our pets health care. Because obviously the mountains of bad reviews isn't evidence or reputable to the snakes oils salesmen. Method of payment please? Oh! And we offer the s***iest insurance plan you can buy too. Trust us, we're the good guys...

If Teddy has shown a reaction to NexGard, it would be best to find an alternative for next time; the diarrhoea will subside after a couple of days, if he is eating normally there is no need to change his food. You can try giving him some plain canned pumpkin to see if that firms up his stool. If you see no improvement after two or three days visit your Veterinarian. Regards Dr Callum Turner DVM

I gave my golden puppy nexguard and he had diarrhea and started scratching also. It has been four days now. I called my vet and she gave him metronidazole twice a day. I will try something else. I wish I would have read more about Nexguard.

To anyone administering drugs to pets: I’m no expert and not pro drug either. It’s a conundrum. Do we feed them poison that has potential bad side effects to prevent disease or do we not feed them poison and risk them getting the disease? I never know quite the right answer. Our pets are as biochemically individual as humans, but what I have found helps just a little is to give them the required dose at the required time with food and water, as well as a good pre and probiotic. It seems to help my sensitive little girl somewhat

Can there be delayed side effects after giving the Nexgard? The first dose I gave my puppies within 15 minutes they were lethargic, trembling uncontrollably, and would not eat. The next morning they were fine and seemed back to normal. The next visit to the Vet I asked about it being safe, which I was assured that it was. I gave them a second dose with no issues, but it's been 10 days and now one of them is having the exact same symptoms.

Callum Turner
Dr. Callum Turner, DVM
1808 Recommendations

There is a lot of negative press about Nexgard online (from forums and social media posts not scientific articles) due to the apparent frequency of reactions to it. In a US controlled field study of 415 dogs; the most common side effect was vomiting which occurred in 4.1% of animals in the study with other reported side effects being dry skin, diarrhoea, lethargy and loss of appetite as well as two out of three dogs with history of seizures had a seizure after administration, the other dog was fine. I am not aware of delayed reactions to Nexgard as reaction usually occur within an hour or so; but if you have some concerns visit your Veterinarian and make sure the affected pup is warm and is hydrated. Regards Dr Callum Turner DVM
www.nexgardfordogs.com/Style%20Library/nexgard/docs/NexGard_PI.pdf

Also important to note, how they peddle this raid in a pill, get your dog sick, then say bring them back to us, will charge you more to shotgun em with more pills that may or may not work. Of course it's not free of charge, because I'm sure we can find a way to say it's the consumers fault. At the very least, it's not the vet! They have no problem playing mad scientist and trial and error with our pets. As long as they get paid. And as far as dr's go, they tend to say I don't know, or let's try something else far more often than actually curing things. I wish my job allowed me to get paid for incomplete & unfinished jobs.

Health care isn't science though. It's glorified drug dealing. Or better yet voodoo. With as many " non-scientific" comments online would be enough for any intelligent person to say no to this drug. And I wouldn't expect for one second that this "Dr" or any other in their profession would actually condemn the drug that they get paid to peddle. There's obviously enough public concern. But we should all close our eyes and ignore the facts, not blame a capitalist regime. Thanks dr Doolittle.

Totally agree more Frontline rubbish

Is a field study of 415 dogs a big enough study given the # of dogs in the US? I dont' think enough research has been done with this product.

I gave our shelter-rescued, approximately-eight-month-old Australian Shepherd mix puppy his first dose of Nexguard today. A few hours later, he crawled under our bed for the first time ever. No, there were no treats or toys under the bed. Since then, he's been more lethargic and shown less energy than we've seen in the entire three weeks we've had him. He is also curled up on our bedroom floor, eschewing both his crate and the surface of his bed, his preferred sleeping locations until today. Should I be worried that this is a negative reaction to Nexguard? Thanks in advance!

Possible side effects of Nexgard include vomiting, diarrhoea, loss of appetite, lethargy and flaky skin. Behavioural issues may be related to lethargy; don’t administer any more Nexgard to Georgie and speak with your Veterinarian about an alternative. If the symptoms persist, visit your Veterinarian for an examination. Regards Dr Callum Turner DVM

It is possible that Skyler had an allergy to NexGard leading to skin irritation. Normal side effects of NexGard are vomiting, dry skin, diarrhoea, lethargy and loss of appetite.

For the next course of flea treatment, try a different product not containing Afoxolaner. Regards Dr Callum Turner DVM

Hi. I gave my poodle her first dose of Nexgard recommend by our vet. It is something i will regret for the rest of my life. Within hours she started vomiting and refused to eat or drink anything. I tried force feeding her. She started panting and breathing extremely fast.
She became extremely week and couldnt stand up. She kept looking up. She had an extremely adverse reaction to Nexgard. This has never been her behavior. I knew it was the Nexgard and that these were symptoms of poisening. I called the vet and he told me to bring her in the next morning and that i should just give her a glucose solution. I also gave her Milk Thistle to try and detox her system as this pesticide stays in the system for a month but unfortunately it was too little too late and before i could take her in to the vet she died that night. I know it was the Nexgard that killed her and i felt so helpless. I should have known better that to poisen my beloved pet. I will NEVER RECOMMEND NEXGARD OR ANY OTHER ORAL CHEWABLE TICK AND FLEA TABLET TO ANYONE WHO REALLY LOVES THERE PET.

SO WHAT IS THE ANSWER TO NEXGARD. Lyn Chalmers. It almost killed my dog. Bloody disgusting and this product has not be tested long enough.

I gave my lab puppy the NexGard and he has scratched more now than he did before we gave it to him. I am very comcerned . This is the 1st time I have ever delt with this medicine. I feel so bad that I gave it to him .

I raise german shepherds and we never had tick or any pest problems in over 12 years..however I was advised by a vet to give this to my dogs.MY DOGS GOT REAL SICK...LOST all their coat..no appetite..weight loss.looks like a rescue dog that don't want to eat.Im real sad about the side affects,,it is strictly poison...they lick and itch intently but now its already in their system.DOES ANYONE KNOW HOW LONG IT TAKES TO WEAR OFF????

I commenced our 9 year old German Shepherd on Nexgard yesterday at tea time. He was on Frontline plus and had started scratching so our vet recommended Newgard. Thankfully I only purchased 1 month. Oh my goodness he was beside himself. Scratching, crying running around, panting. I had to cuddle him and soothe him and I had a calming spray for him and sprayed his body with this to try and help as well as using Aloe Vera natural gel. It went on for over 2 hours before he settled and that was when I lay down on the floor with him. I WILL NEVER USE THIS AGAIN. AND NOT RECOMMEND IT. If Frontline does not work maybe I will try Advantage or advantix as we live in a tick area and have to be careful. We were both so worried last night and I know it was caused by Nexgard. Lyn Chalmers

How long does it take for the side effects of nexguard to wear off...

My German shepherd mutt (not pure bred) has taken 3 doses now of nexgard. Her nose has been dry, her coat got smelly, and is falling out. She has what looks like cradle cap on her back just above her tail and raw spots. I started using this because flea/tick collars gross me out. I had to use something though, because I pulled 5 ticks off of her in one night. I'm so sorry that I opted for this though. Going to the vet in the morning, in the mean time we slathered her in coconut oil which she really seemed to enjoy!

I gave NexGard to my 6 year old 5 pound Yorkie yesterday. Within a couple hours she was shaking uncontrollably and had welts all over her underside up to her ears - they were about the size of dimes - bright red and swollen and it was affecting her breathing. I rushed her to the vet - they rushed her to the back - gave her steroid and prednisone injections as well as fluid. It was the only change in her daily routine so it's obvious it was from the NexGard. I have tried so many natural things and it's difficult to find something that works well - especially after her getting a neuro toxin from a tick that caused temporarily paralysis a few months ago. I will continue my research to find something natural for her. She does have a highly active immune system and has to have monthly allergy shots because her entire body becomes a hot spot - it is severe. So perhaps her system simply couldn't handle one of the ingredients. I think it probably works well for most dogs and the good probably outweighs the dangers - pet owners just need to be aware.

I believe this product killed my dog. She had all the symptoms and I didn't notice because they didn't occur right away but rather over the following weeks. I am throwing out the remaining two squares. I would never give this medicine to another dog. :( My heart breaks. I lost my love.

Have any dogs developed IMPA after taking nexgard? After weeks of testing and treating for lyme disease which two tests were negative she was diagnosed with IMPA, she was put on prednisolone and 30 days of Doxycycline she became extremely bloated, still swollen joints would just lay around, would go out to use the bathroom, walked around a little. 19 days into 80 mg of prednisolone a day I had to put her down. It was two weeks after giving her nexgard that she started showing signs of being sore in her joints. Would just like to have some answers on why she developed IMPA.

There are many social media posts online highlighting the public's anger towards NexGard (afoxolaner) with many people reporting their pet dying or becoming sick (including immune mediated polyarthritis) after they used NexGard on their loved one. I have no reputable scientific evidence to connect the administration of NexGard and the symptoms which Abby Mae developed (and I cannot speculate publicly either). The swelling of the joints may have been caused by a variety of other conditions including trauma, infections, immune mediated disease of unknown origin or clotting disorders (either primary or secondary). Unfortunately, I am unable to give you the answers you are looking for. Regards Dr Callum Turner DVM

That's because reputable info can only come from the drug dealers. Why hold yourselves liable when you can ignore public sentiment and base it on protected " science". Nothing you sell can be that bad, huh? With as many bad reports there are ( and don't forget, we have no choice but trust you docs) let's get this garbage off the market. If only 5% dies from the drugs you peddle, that's still 5% way to much. Hows about we don't pay the docs untill they find the job completely. I'd call that a step forward. I do know scientifically that most jobs require completing a task properly. The biggest problem here the consumer doesn't get a say in how the job is done (or not done) we just visit the vet and the first 2 things they say in the door is " method of payment? & Try out our insurance...

My GSD dog, Houdini is a fixed dog and 125# male. Not realizing that my guys problems started with Nexgard, I have continued on with it. My 50# gal died within 24 hours of her Nexgard, after vomiting all day. My GSD guy has no nuts due to his castaration back in 2008, but to ook at him you would think he is quite the stud. His scrotum is full and they leak a clear, sticky fluid and he scratches, has hair loss continually. He has been to two different vets and they give him pills costing 175.00 and did no good other than cause tumor looking lumps on the outside of his legs. He has weight loss, although he eats. His eyes fill with yellow mating all throughout the day, sleeps all day. He tries to follow me to the pasture but stops, goes back, lays down and watches me. His poop has been black and tarry. I believe the Nexgard has killed him but I refuse to let him stop breathing.

I've given her 2 months of the NexGard now. She is scratching, but very active. She doesn't eat but, is on the skinny side, 35 lbs. Has food out for whenever she gets hungry. I also put my local honey on her food to get her to eat more.
The big thing..she is loosing her hair. She was spayed early April and that hair has not grown back and it's really thin on her chest and back legs. She is not chewing. I've given her oatmeal baths too. I'm not sure if this would be a reaction to the NexGard or if it could be stress related??

Hair loss in English Setters may be due to hypothyroidism which is uncommon in this breed but does occur; other conditions which may cause hair loss are allergies (medication, food, environmental), endocrine disorders (hypothyroidism, Cushing’s Disease, other disorders), parasites (mites like Demodicosis), infections (pyoderma, ringworm), stress and excessive grooming to name a few disorders. You could try using a different form of parasite control for the next few months to see if the cause is the NexGard and for other potential allergens, a trial by error elimination of allergens could be performed but can take months and isn’t always accurate; I would recommend visiting your Veterinarian for skin scraping, allergy testing and ruling out of endocrine disorders.

NexGard

I gave my German shepherd Nexgard 48 hours ago. She had mild diahorrea, but her stool has since hardened up. This morning however, she vomited and has been extremely lethargic since. How long after receiving the medication should be looking for symptoms? She seemed fine the first 24 hours.

Vomiting and diarrhoea may occur after the administration of Nexgard; symptoms usually occur within a few hours (if they appear) and last for a day or two. There may be other causes of the vomiting and diarrhoea including foreign bodies, ingestion of something from outside, mild irritants etc… Just keep an eye on Sandy, if the vomiting occurs for more than a day, visit your Veterinarian for a checkup.

Within 5 hours after giving Nexgard both of my GSDs starting scratching, licking, panting, head shaking...Nothing else changed recently except to feed them both Nexgard tablet. How long until this subsides? Need relief - up all night! How do I give them relief and me - so we can go back to a normal life?

The active ingredient in NexGard (afoxolaner) has a very long half life in dogs and can still be found in the blood a month after administration (which is why it is so effective with monthly dosage); page 11 of the document (link) below shows the plasma concentration overtime. Giving Benadryl at a dose of 1mg/lb may help to reduce symptoms but if the side effects persist, I would recommend visiting your Veterinarian. Regards Dr Callum Turner DVM

Our 20# Yorky experienced the same reactions, including increased breathing/heart beat. I'm taking him off NexGard. This medication has too many similar symptoms from too many different type dogs. It alarms me seeing how many pups have suffered.

We gave our pup Naxgard for the first time yesterday and ever since he jas been shaking his head as if his ears are itching. His eyes are a little puffy too. Can you help?

f the symptoms presented appeared after administering NexGard then the two would probably be linked; there is no real treatment, only to stop giving NexGard and chose a different product. Giving 1mg/lb of Benadryl may help. Regards Dr Callum Turner DVM

My girl got her first dose of Nexgard on May 6th. She's vomited 3 times since (first time was a week or so after taking Nexguard. She recently has started eating less. About the 10th of May, i noticed her hair has a crusty feeling near her skin, and her hair is falling out in clumps, resulting in baldness in those areas. She's completely bald on her ears (inside and out), several sections on her back, most of her front legs, and starting to lose more in other spaces. I don't know if this is an allergy or not, but I'm at such a loss. She was initially diagnosed with a skin infection, but been on antibiotics for a month with no improvement. She was tested for mites and ringworm, everything coming back negative.

NexGard allergies usually present within hours to a day after administration; other conditions may cause similar symptoms like hormonal conditions (like Cushing’s disease) or allergies, other causes like parasites and ringworm have been ruled out already. Other conditions like follicular dysplasia may occur in dogs less than three years of age, although the age of onset in Siberian Huskies is usually less than a year. If there isn’t an improvement, it may be worth having a Dermatologist having a look or a biopsy sample taken from the margin of the hair loss. Regards Dr Callum Turner DV

Our dog has done the same and we took her to a dermatologist and she says environmental allergies and she is on allergy shots but she keeps getting worse so I am going to stop the nexgard cause all this started when I was told that frontline was not as effective and they gave choices to change to and then all this itching ,chewing, licking and hair loss started after putting her on nexgard and yes she did vomit, diarrhea at first but now all this other I have mentioned plus lack of energy and yes she is a husky

I have a 12 yr old Chihuahua that has been taking Nexgard for ~2 yrs. He has not been ill but have others notice loss of hair and trembling. Thinking back it started after I started giving him the Nexgard (2-3 months after). I've not discussed the possibility of these symptoms being related to the Nexgard with the vet, however, he has said he could refer us to a dermatologist (very expensive considering it doesn't bother him) nor explain the trembling. We used Frontline for years with no problems but now the vet says it is no longer very effective in SE Florida, seems there has been an immunity build up. Have you heard of any similar symtons from Nexgard or suggest maybe trying another flea preventative? Thank you for any suggestions you may have.

My 7 yr old Catahoula started getting bald spots about 1 week after the first dose of Nexgard. I have checked his skin for mites and ringworm. Nothing found. If you pull on any hair without tension you will get hair in your fingers. When I called the customer service they said they hadn't had any complaints of hair loss which after reading this that is a false statement.

Chewing skin, paws. Seems frightened.

Hello. I gave my 13 lb, 9 mo old maltipoo her first dose of NexGard approximately 10 days ago. Yesterday, I noticed she has chewed her skin raw under her front leg joint, closest to her chest. She seems more itchy than usual and in distress. Could this be a NexGard reaction? She is a sensitive pup at the best of times. I have Wondercide flea and tick treatment. It's all natural , topical product but I worry about its effectiveness. We do not live in a wooded area but there is wildlife around; squirrels, possum, skunk etc. Thank you.

Generally we would expect to see a reaction from NexGard earlier than ten days. Itching and irritation may be caused by many different causes, I cannot rule out NexGard, but the time frame doesn’t fit. Possible causes may be environmental allergens, foreign body (which she bit out), food allergies etc… Since the trauma is localised, I would suspect that something was on her or irritated her externally leading to her chewing one area, with NexGard you would see more generalised itching.

6 month old English mastiff extreme diarrhea going on 4 days now after nexgard. Have tried to give sweet potatoes and rice to firm up stool. How log will this reaction last

Callum Turner
Dr. Callum Turner, DVM
1808 Recommendations

NexGard induced diarrhoea usually is treated with boiled rice and chicken until the stool firms up and then slowly reintroduce Mowgli’s regular food. The active ingredient in NexGard works for up to thirty days which means that any reaction to the medication may take a while to resolve; usually for the gastrointestinal tract should be shorter (a few more days). If after a week you are still seeing diarrhoea, visit your Veterinarian. Regards Dr Callum Turner DVM

My dog took Nexguard on June 15th, and had extreme Diaherra, looked like chocolate milk.. for 4 days... I contacted my vet who placed my dog on five different scripts. I went to the vet three times over a five day period. Today is July 5th and though he is better, his stools are still Not back to normal and are like soft serve ice cream. I'm hoping that he will back to normal soon since it's almost been a month. I wouldn't recommend Nextguard to Anyone... this stuff did Nothing but make my puppy sick...

I gave my 17 lb Jack Russell a dose on Saturday and within 3 hrs she was almost comatose. She started vomiting and having diarrhea. She would vomit every 3-4 hrs. On Monday I took her to the vet. She was mildly dehydrated and had lost 3lbs. She won't eat but will at least now get up to go out to pee. I am force feeding her pediolite 1/2 every 4 hrs. It is now 3 days. how much longer should she be like this?

My pit, Whiskey, has recently broke out in these bulbs all over her body. She's very itchy. Her mouth is dry and she barely has any energy. We've recently given her NexGard for the first time but I don't know if that caused it. We've tried all kinds of shampoos and medications to help and nothing is working. What could this be??

Callum Turner
Dr. Callum Turner, DVM
1808 Recommendations

Reported side effects declared by the manufacturer are vomiting, dry/flaky skin, diarrhoea, lethargy, and lack of appetite; it could be that Whiskey is having a severe reaction to the NexGard, but this would have to be distinguished from a bacterial skin infection or other skin condition by your Veterinarian. Reactions are either allergic or irritating in nature and itching by a dog may cause the introduction of bacteria into a scratch wound which then causes a secondary bacterial infection. Regards Dr Callum Turner DVM

We started our dog on nexgard and she started having skin issues itching, licking and lack of energy we have taken her to her vet and they chose other routes saying it was not the nexgard but she keeps getting worse she is losing her fur and I took her to a dermatologist and she had allergy testing done was told it was environmental allergies but now that I look back on things I am convinced it is the nexgard so I am thinking about choosing something else for flea and tick to see if that could be the problem she has been on this for six months and doesn't get any better . Your opinion is appreciated about this matter

My German Pinscher also started having skin issues. Losing more hair than usual,
has progressed to bald patches. Started around ears, the only change has been the nexgard.

My American bully had same symptoms. I am as told was bacterial skin infection and treated with antibiotics. He lost patches of hair. Licking and continuing scratching. I had to put a shirt on him due to scratching. He was constantly liking his paws. Lost hair by ears. Now has an autoimmune blood disease and is fighting to live. I totally believe it is the nexgard. I was so upset today I made the vet see me again. His red blood cells are at 21. He is very anemic. Went from 56 pounds to 43 pounds in about a week. If his red blood cells get down to 10 I will loose him. That I heard today. Blood test results will be in tomorrow. I won’t be sleeping tonight. He is almost 4 years old. I feel like I poisoned my own. Dog and killing him by this prescribed med from vet. It should be pulled off the market. Karin Strandnes

I meant to say it also made her itch like crazy. I'm wondering when Nexgard will discontinue this poison, and pay for people's vet bills that they have knowingly poisoned.

I started my dog on this drug ignoring all the warnings from several different sites. Do not give your dog this medication! My girl had a seizure, even though she never has had a history of them. The vet of course said he highly doubted it was the Nexgard. He started her on antibiotics and steroids, and bam 479 dollars later I'm praying this shit leaves her system. She always scratched continuously.
