Nexgard Reviews-Complete Protection Against Lyme Disease


Protecting your dog from getting Lyme Disease can be a real struggle.

Most of the tick and flea protection available,Nexgard protects against lyme disease help protect your dog against ticks and fleas.  They don’t actually protect your dog from getting Lyme Disease, they just lower the chances of them from getting Lyme Disease.

They will have a smaller chance of your dog getting Lyme Disease from them having fewer ticks on them. But if a tick that is infected with Lyme Disease gets on your dog, and it bites your dog, your dog has no protection against Lyme Disease.

That is until now. The Nexgard Reviews that I am going to provide you will show you something different from other tick and flea protection, because it provides a complete protection against lyme disease.

Nexgard Chewables

Nexgard is the only FDA approved protection to prevent infections that cause Lyme Disease in dogs. It not only killsNexgard Chewables fleas and ticks, but it also is shown to prevent transmission of the bacteria responsible for causing Lyme Disease.

It will kill infected ticks before they can transmit the Borrelia burgdorferi infection to your dog.

Nexgard is the first and only flea and tick control product for dogs to receive FDA approval for preventing the infections that cause Lyme Disease.

Nexgard Chewables kill adult fleas and prevents fleas infestations. It also kills ticks. It prevents infections that causes Lyme Disease in dogs as a direct result of killing Ixodes Scapularis vector ticks.

It omes in a soft beef flavored chew, that is safe for puppies as young as 8 weeks of age, weighing 4 pounds or more. One chew works for a full 30 days. They are available in 4 sizes making is possible to get the right dosage for whatever size your dog is.

Nexgard only contains one ingredient, Afoxolaner, which absorbs into the bloodstream and causes uncontrolled activity in the fleas’ and ticks’ nervous systems, resulting in death. After it is ingested, Afoxolander is slowly expelled from your dog’s body through their metabolism, which is how Nexgard remains effective for a full 30 days.

Your dog can take Nexgard with or without food. Make sure to watch your dog after you give them the medication to be sure that they have consumed the complete dose. If for some reason that your dog vomits within 2 hours of administration, redose your dog with another full dose.

Lyme Disease

Lyme disease is the most commonly diagnosed tick-borne disease in dogs in the United States. In 2017, more than 300,000 dogs tested positive for exposure to Borrelia burgdorferi. This is the bacteria that causes Lyme Disease, and the risk continues to grow as the range of ticks continues to expand across the United States. This is according to the Companion Animal Parasite Council.

Nexgard controls Black-legged tick, American Dog tick, Lone Star tick and Brown Dog tick which all of these can carry the Borrelia burgdorferi infection that causes Lyme disease.

Drawbacks of Nexgard Chewables

The largest drawback of this product is that a tick or flea needs to bite your dog to be affected by the medication. That means that your dog could end up with skin irritations from the flea or tick bites that could lead to possible hot spots. There are many flea and tick protection choices available that don’t require your dog to be bitten before it actually kills the tick.

You can read the Scalibor Collar Review here. This protection kills ticks just by having contact with your dog. It doesn’t kill the infection that causes Lyme disease though like Nexgard does, but there are less chances of your dog bringing ticks into your home with the Scalibor Collar.

Another drawback, but a very small drawback, this is available as a prescription medicine only. You will need to either purchase directly from your veterinarian or get a prescription from your veterinarian and purchase from an online pet store with your prescription.

Possible Side Effects Of Nexgard

Reported side effects include vomiting, itching, lethargy, diarrhea and lack of appetite. The safe use of Nexgard in pregnant, breeding or lactating dogs has not been evaluated. Use with caution in dogs with a history of seizures or neurological disorders.

Nexgard Reviews

Nexgard reviews are very positive from dog owners who use this product. They rate this product at 4.97 stars out of 5 stars. To have the protection of knowing that your dog isn’t going to get Lyme Disease is very reassuring. This is the only product available that protects your dog even if they get bit by an infected tick. There isn’t any other product available at this point that can give your dog total protection.

The one issue that I do have with Nexgard is that ticks have to actually bite your dog in order for it to die. I am not aNexgard Reviews big fan of my dog bringing ticks into the house that crawl off of the dog and crawl onto me or my family.

There are other tick protection products available that will kill ticks on contact with the dog, but they don’t protect the dog from Lyme Disease if one survives and bites your dog.  You do have the option to use both Nexgard and the Scalibor Collar together to get the best protection.

Laboratory studies show that Nexgard began to kill fleas 4 hours after initial administration and proven 99% effectiveness at 8 hours and is 100% effective for ticks within 48 hours.

It is important that you chose some type of product to help protect your dog from ticks and the possibility of contracting Lyme Disease.

  1. Dear MARLA

    This is my first time to know a word ‘Lyme Disease’ in english word. In Cambodia, i see many dogs having problem with this disease. They don’t receive any care from peoples, because most Cambodian peoples don’t care much about pet. Your article can be benefit to us. We can know more and learn more from your article. 🙂 

    • Thanks for reading Piseth.  Please share this information with others from your country to help all dogs have a better life.  They truly can be a best friend.  

  2. My very first dog died from Lyme disease not long after he returned home through the woods and I picked giant ticks out of his ear. This was oil the mid 90’s before people knew a lot about Lyme disease and before such effective treatments were available. While I’m sure Dingo would have died years ago from old age, I only wish he’d been able to live a longer life than he did, because he really was an amazing, lovable dog.

    • I am very sorry that you lost your dog to lyme disease.  I believe that the protection has greatly improved since the 90’s.  At this point, Nexgard is the only FDA approved prevention against your dog ever getting lyme disease.  It seems that all dogs go before it should be their time.  Thanks for sharing your story.  

  3. This sounds like a great alternative!  I have two little boys that I get flea pills for monthly from the vet.  They are expensive and I do not know that they guard against anything else actually.  I love my boys and I want them to be protected.  I am going to click on your links and do a little more research.  They are about do for their next pill, and I might just switch!

    • I am glad you found valuable information to help your dogs.  They are worth protecting.  I have always used flea and tick protection for my dogs, but I have still always worried about them getting lyme disease since they still get ticks attached to them even with the protection.  With Nexgard, at least I will know I will be protecting them against getting lyme disease and knowing I am giving my fur babies the best protection possible.  Just a reminder that Nexgard is only available with a prescription.  

  4. Hello Marla, 

    Thanks for such an informative article about Lyme Disease and our favorite four-legged friends. You know, I never really thought about dogs and the disease. I know for myself that I have very sensitive skin and when I go ‘out into Mother Nature’, I am ‘over-dressed’ to ensure that those mites don’t get ‘close enough’.

    Now, I need to think about my dog as well. We do go for walks, but not much in the nature. In any event, at least now I know how to take care of him if the little critters ever get close.

    Thanks so much.


    • Michelle, some areas of the country are worst then others for ticks, but don’t rely on the fact that you aren’t in a woods or long grass that your dog won’t get ticks.  That is where they are mostly found, but I have gotten a tick in short cut grass near the house.  It is best to always be safe.  

      Thanks for leaving me a comment and for reading my article.  

  5. Hi I was wondering what the effects of Lyme disease are?  It would be terrible for any dog to get the disease, is there any other way to get infected rather than by ticks and fleas? The possible side effects leave me a bit concerned.  What are the chances of getting those side effects?

    • Peter, thanks for your comment and questions.  The effects of lyme disease could include stiff joints, lethargy, lameness and fever.  Here is a great article on dogs and lyme disease and the symptoms.  A large problem with lyme disease is that it is hard to figure out of that is the problem.  Most of the symptoms are the same for many other things, and lyme disease is usually a process of elimination, since it doesn’t always show up in blood work.  The only way to contract lyme disease is from being bit by an infected tick.  Proactive protection is the best way to avoid lyme disease.  

  6. I must say that I have not have a experience with this product but as I see it is trusted and FDA approved which is very important for me. We should pay more attention on our dogs and give them quality medications instead of some cheap products. My cousin’s dog has this type of disease and I will definitely forward him this article.

    • Daniel, I agree with you about making sure we provide our dogs with the best protection possible.  Lyme Disease is nothing to mess around with.  In some cases, treatment for lyme disease will help your dog, but there are several cases where you just aren’t able to get it under control, or when it seems to be gone but symptoms can reappear years later again.  Please do forward the article to your cousin, and I hope his dog is doing ok.  

  7. The problem with nexgard is that the teak should bite the dog before it can die, i am just imagining my self having my dog in my car with the teaks stil sucking blood from my dog and dirtying my car as it dies and falls. I strongly agree with you that Nexguard and the scalibour collar are the best together, This is really need to have to get rid of teaks.

    • I do feel that it is a real drawback with the Nexgard product that the tick has to actually bite your dog to die, but the ability to completely protect your dog from ever getting lyme disease is a great positive.  I strongly recommend using both the Scalibor Collar and the Nexgard together.  I currently use the Scalibor Collar, and rarely do I see any ticks on my dog, but once in a while one will get attached to my dog.  When using Nexgard with the Scalibor Collar, you are providing your dog the best protection to keep them safe.  

  8. I dont understand how my dog that has been on NexGard has come up positive for lyme disease … I am reading all this and the main thing its supposed to do is prevent it…

    • I just had a regular vet visit yesterday with my German Shepherd, and he’s been on Nexguard since March, and before that we used the Soresto collar on him. He also gets his monthly Heartguard chewables religiously. I don’t mess around with this sort of thing, and he’s an only furbaby. Well, his blood work showed he was positive for Lyme Disease and Ananplasmosis (which effects the white blood cells). Needless to say, this was very upsetting news to hear when we originally went in for a regular heart worm check up. Didn’t think we would come out $600 later, having multiple blood tests, and testing positive for the aforementioned 🙁
      Is the vaccine any more successful in preventing Lyme??

  9. Is it possible that your dog had lyme disease before they were put on NexGard? Has there ever been a time that your dog didn’t receive the dosage more than 30 days out. It can take up to 48 hours to be completely effective, and if your dog received their treatment 32 or 33 days out, that would give a small window of time that they could have been infected by a tick with lyme disease. Let me know, because I would like to keep all my information correct. I am sorry that your dog has lyme disease. Hopefully it was caught in the early stages.

  10. my boy has been on Nexgard for 5+ years, I haven’t missed any doses. At his annual wellness exam, his doctor said his bloodwork had elevated levels indicating Lymes and wants to put him on Doxy for 30-days. I’d like to know how is this possible?

    • I am very sorry to hear that. Nexgard has an effective rate of over 99% protection, so I am surprised since you haven’t missed any doses. I will do some more research, and see what additional information that I can find for you.

  11. My dog has been on Nexgard as long as I’ve had him. At his exam in June he tested positive for Lyme disease. Boehringer paid for his treatment, but how can I be sure he won’t be infected again?

    • Unfortunately, there aren’t any products that will guarantee that your dog won’t be infected again. I have been using a Seresto collar for the last couple of years for my dog, and I haven’t had any issues. My dog is in long grass daily, and there are lots of ticks where I live. This product has worked best for me.
