NexGard Reviews: All Your Questions Answered

At some point you will deal with a flea infestation in your dog. This is more common when the household is shared with other animals, and where the climate stays warmer year-round.

Flea control is a central part of maintaining a healthy and happy canine!

What is NexGard?

NexGard is a chewable tablet that claims to kill 100% of fleas in 24 hours. It is a beef flavored soft chew that will also control ticks.

This tablet formula was created Frontline (the same company that makes Frontline Plus – a topical flea treatment).

How Do You Use NexGard?

Using NexGard is simple – all you have to do is feed it to your dog like a treat.

According to NexGard’s website, 89% of dogs will eat the NexGard chew without hesitation. Although some dogs are very cunning with medication, and you may have to hide the tablet, in a pill-pocket or a piece of cheese or lunch meat.

NexGard is made in different strengths for different sized dogs. Your vet will be able to help you in making sure your dog is administered the proper dosage.

For larger dogs (over 120lbs) you may need to administer the proper combination of tablets to ensure it is effective.

How Long Is It Effective?

The medication is absorbed into your dog’s bloodstream and will protect against fleas for 30 days. Just as effective as any topical flea solution, NexGard is making many pets and pet parents happy with a simpler solution.

Don’t worry if after the first 24 hours your dog is still itching. After 24 hours all the fleas on your dog will be dead.

The continued itching is due to the flea bites that your dog already has and it will stop within a day or two.

Nexgard will also control the following:

  • American dog tick
  • Black-legged tick
  • Brown dog tick
  • Lone Star tick

Ticks are particularly nasty pests, and you should always be checking your dogs skin and coat for them.

Are There Any Side Effects?

While side effects are extremely rare there are some cases where side effects occur.

The most common side effects in dogs are vomiting, lack of appetite and dry or flaky skin. If any of these symptoms persist, then you should contact your vet immediately.

What About Benefits?

The main benefit of this oral medication is the ease of treatment. The downside is the cost. It’s typically around 30% more than using a topical ointment.

This is one of the very few oral medications that fight off both fleas and ticks.

Bravecto vs NexGard

There are always options out there, no matter what you are looking for.

Bravecto is effective for 8-12 weeks (8 weeks for lone star ticks, 12 weeks for other ticks and fleas), while NexGard is effective for only 30 days.

Bravecto cannot be used on dogs under 6 months of age or under 4.4lbs while the latter can be used after 8 weeks of age or dogs 4lbs or more. This can mean your dog may not be able to take Bravecto anyway.

Between the two, dogs taking Bravecto are 2% more likely to suffer from side effects such as diarrhea, vomiting, and loss of appetite.

If you are making the decision between the two, I personally would go with NexGard, even though you can give the medication less often with Bravecto.

You can order NexGard from (prescription required). Discount available with Autoship option.

    I don’t remember if I gave my dog her nexguard this month. Should I give her one now or wait a month?

      I always give my dog’s their Nexgard on the 1st and Heartgard on the 2nd that way there’s no question. You could put one of those stickers on the day after you give it. You would know for sure then. I have a dog that ate her dose (med size) the other dog dropped his (LG size) and she promptly ate his also. So I called my Vet to make sure there wouldn’t be an overdose and she said that the dog may or may not vomit but that there shouldn’t be any problem. And there wasn’t.

    The NexGard I get is hard as a rock. How do I soften it up so the dogs can chew it?
