How Does NexGard Work?

NexGard chewable tablets are available in four flavors for dogs of different weights. NexGard extinguishes fleas within 8 hours and ticks within 48 hours. After being given, its effects last for at least five weeks against fleas and up to one month against ticks

Nexgard is manufactured by Merial Animal Health which is now part of Boehringer Ingelheim, the same company that manufactures:

So you know this product can be trusted. 

So how do they do it? 

The active substance in NexGard, afoxolaner, is an ectoparasiticide that kills parasites on the skin or the dog's fur, such as fleas, ticks, and mites. Once the flea and ticks start feeding on the dog's blood, the active substance becomes effective.  

Afoxolaner extinguishes parasites by driving an over-stimulation of their nervous system. Afoxolaner blocks the regular activity of charged chloride particles in and out of nerve cells, specifically those associated with gamma-aminobutyric acid. As a result, this substance conveys messages between nerves resulting in uncontrolled movement of the nervous system, paralysis, and death of fleas, ticks, and mites. 

Afoxolaner kills fleas before they lay eggs, which helps contaminate the dog's environment. As a result, these fleas, ticks, and mites rise to the top of the dog's haircoat as they die.

NexGard's active ingredient, afoxolaner, kills fleas and many tick species, which include: 

  • Black-legged ticks
  • American Dog ticks
  • Lone star ticks
  • Brown Dog ticks. 

NexGard is tested and approved for use on pups as young as eight weeks old and doggies over four pounds. The chews are also safe to give to canines presently taking other medicines Nexgard is four for dogs with different weights. In addition, because it is delivered internally, Nexgard is suitable for use on pets that swim and are washed regularly, saving you the fuss of topical medicines. However, Nexgard is not evaluated for use in breeding pets, so you should not give it to pregnant, nursing, or breeding dogs. Instead, discuss Nexgard for dogs with your Vets to provide your dog with intense relief from flea & ticks with monthly tasty chew.

Two sweet girlies decided to make our deck their home. Mosquitoes are a big problem where we live and we had to get them protected. This was the best bang for the buck. I’ve ordered from 79Pets several times and while delivery is not fast it is very consistent.

As a retired veterinary technician I was extremely happy to finally see a flea and heartworm medication that actually does tapeworms too!!!!!!! This is a 1st to my knowledge....I live in a tropical climate where fleas never die so this is heaven sent.

After Seresto collars failed to get rid of fleas, I didn't know where to turn. I saw a post on a page I follow (Kentucky Kitty Cats) saying that they use Nexgard Combo for the cats they shelter. I decided to try it and IT WORKS!

This is Lexi Marie! She was wondering why mom was so excited for buying flea medicine. I explained to her that we saved $100 and that she would understand some day when she grows up.

Customer photo review of Revolution Plus For Medium Cats 5.6-11 lbs (2.6-5kg)

Last year, I made a visit to the vet. I told them that Kattie/cat had ear mites. They gave me an ointment costing $80canadian. I used it up and purchased another bottle. $160. total not including the cost of the vet visit. No results. The ear mites have been there for a long time. Canadian vets have control of what is sold in Pet stores and you cannot purchase off the shelf products not recognized by them. I jumped at the chance to purchase your produce with a recommended 100% effectivity. I was willing to try, but was suspicions. After a month there was still a little scratching but after 6 weeks, the mites are gone and the scratching is gone. Thank you very much for this mite solution. I recommend it heartily. Harry P.S. Do not tell the Canadian vets as they will outlaw your product.
