NexGard is a new treatment against fleas and ticks for dogs. It is provided as a beef-flavoured, chewable treat to be given once a month. NexGard makes it very easy to provide safe and effective treatment for both of these important parasites and most dogs enjoy the tablets too. NexGard is for use in dogs only.

NexGard contains the active ingredient, afoxolaner, an insecticide that was discovered relatively recently. While the ingredient is FDA-approved and safe for use in dogs, fleas and ticks fare much worse against it. Afoxolaner is toxic to parasites, attacking their nervous systems and killing them within 24 hours (Note: ticks can take slightly longer to die). Once the ingredient is ingested by your dog, it is quickly absorbed into the bloodstream and distributed throughout the body.

Unlike spot-ons which kill parasites on the skin’s surface, NexGard only gets to work when the flea or tick takes its blood meal. This means your dog has to be bitten before NexGard can take effect. Whether or not parasites are killed before they have chance to transmit disease has not yet been determined.

So, why choose an oral treatment over a topical one?

NexGard is different to other oral flea treatments on the market that are unflavoured and need to be disguised in food as it is both chewable and palatable, with a recent study showing that 89% of dogs would readily consume it. NexGard beef-flavoured chew offers full-body protection against fleas and ticks, gets to work quickly and eliminates parasites for a period of 30 days.

Being an oral treatment, NexGard is convenient for several reasons. Topical preparations can be messy and difficult to apply but with NexGard, administering the treatment couldn't be easier. Spot-ons contain oily insecticide which tends to leave greasy residue on the coat. In some cases, hair loss is evident on the scruff of the neck where flea treatment has regularly been applied. Oral treatments eliminate mess and won't leave grease patches behind.

Using an oral rather than topical treatment is also safer when it comes to exposing your children and/or cats to it. Some spot-ons contain the potent ingredient permethrin, which is toxic to cats and can be fatal. The risk to your cats might be small but it's not worth chancing it when there are so many different products on the market that don't contain permethrin. Administering a tablet won't leave a slimy residue on your hands or matt your dog's coat together. What's more, your dog won't be trying to rub it off as soon as it's been administered!

NexGard and other oral treatments have the added benefit of being unaffected by baths and when you wash your dog. Topical treatments usually come with instructions not to bathe your animal for 48 hours after use because they will wash off, but with NexGard, there is never any need to worry about your dog getting wet and having to re-apply the product.

NexGard is a safe and effective treatment for infestations of fleas and ticks, killing them before they have chance to lay their eggs. The treatment can be used in puppies from the age of 8 weeks and in animals weighing over 4 lbs. NexGard is for use in dogs only.

Indications for use

Treatment of flea infestation in dogs (Ctenocephalides felis and C. canis) for at least 5 weeks. The product can be used as part of a treatment strategy for the control of Flea Allergy Dermatitis (FAD).

Treatment of tick infestation in dogs (Dermacentor reticulatus, Ixodes ricinus, Rhipicephalus sanguineus). One treatment kills ticks for up to one month.

Fleas and ticks must attach to the host and commence feeding in order to be exposed to the active substance.

Special warnings for each target species

Parasites need to start feeding on the host to become exposed to afoxolaner; therefore the risk of the transmission of parasite borne diseases cannot be excluded.

Special precautions for use in animals

In the absence of available data, treatment of puppies less than 8 weeks of age and/or dogs less than 2 kg bodyweight should be based on a benefit-risk assessment by the responsible veterinarian.

Questions & Answers for NexGard for Dogs

Below are some recent questions we've received regarding NexGard for Dogs, including answers from our team.

Ask Your Own Question

Nexgard query

13th Oct 2015

Is the Nexgard you sell the Nexgard Spectra that prevents ticks as well as fleas and worms?

John Cousins
  • Veterinary Surgeon

We have just added NexGard Spectra to our website. This is the version which also treats heartworm and intestinal roundworms. Both types of Nexgard treat Fleas and Ticks.

Can it be used to keep Demodex away

30th Sep 2015

We have a rescue dog who had severe Demodex mange .. would this be suitable to keep the mites under control.

John Cousins
  • Veterinary Surgeon

This product is not licensed to be used against mites and I doubt it would work. I normally recommend using Advocate in this situation. They are prescription products so you will need to talk to your vet anyway about what to do.

Prescription every time?

24th Sep 2015

Hi when we order nexgard do we have to get a vet prescription every time? As the vets charge £12 per prescription and that takes the price to what they charge

  • Veterinary Nurse

Some vets will write out a prescription for 6 or 12 months worth of treatment, some will include more than one animal on the prescription of you have them. Others seem to want to write out a prescription and charge for it as often as they possibly can. There is no fixed rule on this and vets can do whatever they want. Some are kinder than others. Basically it is up to your vet how helpful he or she is and sometimes it is not worth buying online. You can ask your vet to provide for a longer period's worth of treatment. They might make an excuse and decline to, but they can certainly do so if they want.

Safe use with other oral products

7th Aug 2015

Is this product safe to use with other complimentary oral products such as capstar and programme?

John Cousins
  • Veterinary Surgeon

Ideally it should not need to be used with other products, but it is very safe and in a different class of drug to the non-prescription flea treatments, so it should be perfectly safe to use them together.

Dosage time span

17th Jun 2015

how long do you administer this product for, do you have to give the dogs the chew periodically for life,? or summer ? or until fleas have gone ?

John Cousins
  • Veterinary Surgeon

This is pretty much the same answer for all monthly flea treatments. Ideally you give a dose once per month every month for the dog's life. That way you will provide the best possible parasite control. If you do it less often than that, such as just through the summer, then you might be OK but you might not. It will depend on environmental factors such as how many non-treated animals go to the places where your dog goes and the temperature/humidity etc. (Fleas are not too particular which animal they bite. Most fleas found on dogs are cat fleas, but dog fleas, hedgehog fleas, human fleas and others are commonly identified if this is followed through.) Providing treatment for the peak flea season will be adequately effective in a proportion of situations, but in others it will prove inadequate. Once a flea population has built up, it takes a while to get rid of it, however effective your treatment then becomes.

Ticks do tend to be much more seasonal than fleas and if these are your primary concern, you do not perhaps need to treat your dog over the winter. Ticks seem anyway to be rare in some areas and very common in others, so this is relevant too.


2nd Apr 2015

These tablets come in packs of 3 for dogs 25-50KG. What is the dosage? ie. One tablet a month?

Richard Spratley
  • Web Developer

That is correct, the treatment schedule is to administer at monthly intervals throughout the flea and/or tick seasons.
