NexGard Spectra Review | What Is NexGard Spectra for Dogs?

Before we go any further, you must first understand exactly what the product is and how it works. So, what is NexGard Spectra?

NexGard® Spectra™ was first approved for distribution by the European Commission on January 15, 2015, almost a year after the successful launch of NexGard® in the United States. It was then that NexGard Spectra for Dogs was created by Sanofi and Merial, two world-leading companies in animal healthcare that later became a part of Boehringer Ingelheim, a global pharmaceutical company for animal health.

Available as a chewable tablet, NexGard Spectra for Dogs was created to eliminate internal and external parasites in 30-day increments that can even be used on puppies as early as eight weeks of age that weigh at least 2 kilograms.

What does NexGard Spectra Cover?

The majority of dogs will be affected by parasites, like fleas or ticks, at least once in their life. Both internal or external, parasites are any organisms that live on or feed off a host at the host’s expense. These parasites can cause great harm to your dog in various ways, such as inducing anemia. So, what does NexGard Spectra cover?

NexGard Spectra UK and NexGard Spectra AU

NexGard Spectra for Dogs covers both internal and external parasites. Fleas, ticks, and gut worms can all kiss their time infecting your dog goodbye with NexGard Spectra UK. That means fewer trips to the vet and less money spent on ineffective medications.

Unfortunately, NexGard Spectra for tapeworm does not work. But do not fret! According to the product label for NexGard Spectra Australia, the chewable tablet helps prevent the following internal and external parasites:

  • Fleas
  • Paralysis ticks
  • Brown dog ticks
  • Bush ticks
  • Heartworms
  • Roundworms
  • Hookworms
  • Whipworms

NexGard Spectra for lungworm prevention was finally licensed in 2017, but it is unclear whether this applies only to NexGard Spectra AU or if it includes NexGard Spectra UK.

All in all, the next time that you find yourself asking “what does NexGard Spectra cover?” you can rest assured that NexGard offers protection against most parasites, although not tapeworms.

NexGard Spectra Ingredients

Each tablet of NexGard Spectra for Dogs contains 1.9% of Afoxolaner and 0.4% of Milbemycin Oxime. What, exactly, are these ingredients?

  • Afoxolaner is a broad-spectrum antiparasitic used to kill external parasites like fleas and ticks.
  • Milbemycin Oxime is an endoparasiticide and ectoparasiticide, which means that it kills both internal and external parasites, such as heartworms, mites, or intestinal worms.

While effective for lungworm, NexGard Spectra for tapeworm is ineffective. However, tapeworms are transmitted when a dog ingests a flea that has been infected with the tapeworm larvae. So theoretically NexGard Spectra for tapeworm is a good tapeworm prevention product.

Lungworms, on the other hand, get transmitted when a dog eats slugs or snails that have been infected with the worm larvae. NexGard Spectra for lungworm is effective at eliminating these internal parasites. To prevent lungworms from taking over the lungs or heart of your dog, NexGard Spectra for lungworm is vet recommended.

For example, one NexGard Spectra reviewer states that:

We’ve given our Mini American Shepherd Nexgard since he was a puppy. Never had any adverse reactions. He’s now 1 year and 3 months old and still loving his NexGard. We’ve never seen a flea or tick on our guy except for the one month that I didn’t give him his Nexgard. It was winter, and thought I could get away it. But near the end of the month with no meds we found a deer tick. So, he’s on it year-round now, with no breaks in the cycle. And our home and puppy are totally bug-free. And the bonus is that he loves taking his medicine!

Another NexGard Spectra reviewer was thankful for her veterinarian recommending NexGard Spectra for her dogs:

I have two heelers and have never had luck with front line and didn’t enjoy fighting to get the normal flea pill shoved down their throat. My vet recommended this a year ago and amazingly enough they eat it up and think it’s a treat!! That’s the most handy part!! Now however they do experience the itching side effect for a week but then are good to go!! I recommend this product.

Although NexGard Spectra UK reviews are difficult to find, we found a few reviews on VioVet that recommend NexGard Spectra for Dogs, also praising the medication for being effective and more affordable than other products out there.

We spend most of our time in France. The dog was bitten by a tick and became very ill with major organ failure, it cost 2000 to fix her. She had a special collar and Frontline, the vet said that both are ineffective against ticks and recommended Nexgard. I cannot comment on its effectiveness, the vet said this is the best.

On, all but one of the twelve people who submitted a NexGard Spectra review gave the product 5-stars. Specifically, one NexGard Spectra reviewer says:

Great all-round product not the cheapest, but ticks all boxes. Great price compared to vets prices. Prescription required to be obtained from the vet to complete purchase.

I started giving my dog first dose of NexGard Spectra in January 2020 and two months later another dose in March. By the very beginning of May, my dog had a terrible seizure in the middle of the night which lasted around five minutes, very frightening experience, after that she shows signs of neurological damages, not walking properly, loss of balance, very weak, loss of some sight and hearing. I think this drug is toxin to dogs, really should be banned. DON’T take the risk!!!

The author of another NexGard Spectra review laments ever listening to the veterinarian’s recommendation, saying:

NexGard made my puppy sick! Vet suggested I get the stuff, wish I never did!! when I first got him home he was drooling to the point he was soaking wet! he has been having watery diarrhea for the last 5days since having NexGard… Now he has started vomiting and doesn’t look good at all!!

AdvisoryHQ’s Conclusion: Is NexGard Spectra Safe? Is NexGard Spectra the Best Parasite Treatment for Your Dog?

There will always be risks and side effects to consider with any flea and tick medication you use on your dog, as with any other form of the drug.

Even though NexGard Spectra in Australia may be more readily available as an over-the-counter medication at an affordable price, consulting with your veterinarian before you make the purchase can very well be the difference between safe and dangerous for your dog.

Is NexGard Spectra safe? Are NexGard Spectra ingredients effective yet gentle on your furry friend? Based on the NexGard Spectra UK and AU reviews, we can conclude that the answer to those questions varies from case to case.

While some dog owners in the UK are raving about the to-the-point flea and tick solution, a large part of NexGard Spectra reviewers report going through a nightmare with the product, leaving us with many questions about the effectiveness and risks of NexGard Spectra UK and AU.

The NexGard Spectra reviews in the UK are few in comparison to the reviews from Australia but still point towards an affordable NexGard Spectra online price.

The NexGard Spectra prices appeal to people from all economic backgrounds who still wish to prevent parasite infestations in their pets, with the NexGard Spectra 6 pack being one of the most popular.

Still, despite the consistent praise from NexGard Spectra UK reviewers, based on the high volume of negative feedback from dog owners who purchased NexGard Spectra Australia, we have decided to give the product an overall rating of 3-stars. We hope that this rating will instill caution in potential buyers, and urge all buyers to consult with a Vet.

The high number of negative NexGard reviews and the low number of NexGard Spectra reviews in the UK may be due to upset customers being more incentivized to review the product than happy customers.

Additionally, treating your pet with NexGard Spectra for lungworm and other nasty parasites might still be worth it, regardless of the possible side effects, as long as the medication is being administered correctly.

After all, the NexGard Spectra side effects can be diminished if you buy the correct dose for your dog. Remember, buying NexGard without a vet prescription in the UK can result in dangerous consequences for your pet.

However, although the NexGard Spectra prices might seem tempting, we urge all dog parents to first book an appointment with their local veterinarian to discuss the potential NexGard Spectra side effects before giving your pet any medication. That way, you can properly assess the health risks and create the right action plan so your pet can continue living a happy, healthy, and pest-free life.
