Bravecto vs NexGard in NZ (2026): Which Flea Treatment Is Better for Your Dog?

Quick answer

If you want the default recommendation, pick Bravecto. It is the better buy for most NZ dogs because one chew lasts 12 weeks, the monthly cost is usually lower, and it covers mites as well as fleas and ticks. Pick NexGard if you prefer monthly dosing, have a fast-growing puppy, or want an easier step up to NexGard Spectra later.

Bravecto vs NexGard: the fast takeaway

• Best for most adult dogs: Bravecto
• Best for puppies and monthly dosing: NexGard
• Cheaper per month: Bravecto
• Broader mite coverage: Bravecto
• Simpler upgrade path to all-in-one treatment: NexGard

I keep Māui on Bravecto — quarterly dosing suits my memory, and it’s been reliable for years. But I’ve used NexGard in the past without issues. Neither is a bad call.

What they are

Both are oral flea and tick chews you get through NZ vets and authorised pet pharmacies. Both are prescription products. Both belong to the isoxazoline drug class (fluralaner in Bravecto, afoxolaner in NexGard), which means they kill parasites via your dog’s bloodstream after a flea or tick bites. Most dogs eat them like a treat — similar to how they’ll happily take dental chews for oral health.

The key difference is the dosing interval — and that flows through to cost, convenience, and flexibility.

Head-to-head

Duration

• Bravecto: One chew, 12 weeks of protection
• NexGard: One chew, 4 weeks of protection

Three months vs one month. If you’re someone who regularly forgets to reorder (no judgement — I’ve been there), that’s a meaningful difference.

Parasite coverage

• Bravecto: Fleas, paralysis ticks, brown dog ticks, bush ticks, demodex mites, sarcoptic mange mites
• NexGard: Fleas, paralysis ticks, brown dog ticks, bush ticks

Bravecto’s mite coverage matters if your dog has had mange or recurring skin issues. Dogs with ongoing skin sensitivities may also benefit from hypoallergenic dog food to address potential dietary triggers. For a typical NZ dog that just needs flea and tick protection, they’re equivalent.

What neither covers

Neither product touches worms. If you want an all-in-one, look at NexGard Spectra or Simparica Trio instead. If tapeworm cover matters as well, our Best Worm Treatment for Dogs in NZ guide explains the gap.

NZ pricing

Approximate pricing for a medium dog (10–25 kg), March 2026:

	Single dose	Monthly cost
Bravecto	$45–65 (3 months)	~$15–22/month
NexGard	$18–28 (1 month)	$18–28/month

Bravecto works out roughly 15–25% cheaper per month across most weight classes. The exact gap varies — worth checking with your vet or pharmacy for your dog’s weight. For dogs requiring ongoing parasite treatments or multiple medications, pet insurance can help manage annual veterinary costs.

Bravecto: pros and cons

Pros

• One chew every 3 months — lowest hassle of any oral flea treatment
• Cheaper per month than NexGard across most weight classes
• Covers demodex and sarcoptic mange mites — NexGard doesn’t
• Less frequent dosing means fewer opportunities to miss a treatment

Cons

• 3-month commitment per dose — if your dog has a reaction, you can’t “undo” 12 weeks of the drug
• Not ideal for puppies whose weight changes quickly (monthly dosing is easier to adjust)
• Some vets prefer monthly monitoring capability for dogs with health conditions

NexGard: pros and cons

Pros

• Monthly schedule gives you more control and flexibility
• Easier to adjust dose if your dog’s weight changes (common in puppies)
• Direct upgrade path to NexGard Spectra for worm coverage, same drug family
• Better choice if you want shorter observation windows after starting a new treatment

Cons

• More expensive per month than Bravecto
• Monthly reminders are easy to miss — gaps in coverage are more likely
• Doesn’t cover mites

NZ parasite context

NZ doesn’t have paralysis ticks (that’s Australia’s problem). What we do have:

• Fleas — year-round across most of NZ, peak November–March (they slow down in winter but don’t disappear — year-round protection is still worth it)
• Brown dog ticks — present but uncommon compared to Australia
• Bush ticks and cattle ticks — relevant for dogs on rural properties or spending time in native bush

For most NZ dogs — suburban, on leads, occasional park visits — flea coverage is the main priority. If yours is a working or adventure dog with regular bush access, tick coverage earns its weight. Regular dog shampoo can also help with flea prevention as part of a broader care routine. For adventure dogs in NZ bush, pairing your flea treatment with a durable harness is worth thinking about too.

Working dogs and active breeds also benefit from quality nutrition to support their immune system — see our breed guides for German Shepherds, Labradors, and Border Collies for feeding recommendations. Consider pairing good nutrition with omega-3 supplements for skin health and probiotics to support overall immune function.

Which one suits your dog

Choose Bravecto if:

• You want less hassle — three months and done
• Your dog has had mange or mite issues — Bravecto covers these, NexGard doesn’t
• You want to save money — it’s cheaper per month for most weights
• Monthly reminders have a habit of going missing
• Your dog has sensitive skin conditions that benefit from less frequent medication exposure

Choose NexGard if:

• You prefer monthly dosing and the control it gives you
• Your dog has reacted badly to fluralaner (Bravecto’s active ingredient) in the past
• You want the option to upgrade to NexGard Spectra later for worm coverage, without switching drug families
• You have a puppy under 6 months — both are approved from 8 weeks, but some vets prefer monthly dosing for pups whose weight is changing fast (see our puppy food guide for nutrition during this rapid growth phase)

What about NexGard Spectra?

If you want flea, tick, AND worm protection in one monthly chew, NexGard Spectra is worth a look. It adds milbemycin oxime to afoxolaner, covering roundworm, hookworm, whipworm, and heartworm alongside fleas and ticks.

The trade-off: it costs more per month (~$25–40 for a medium dog) and is still monthly. But if you’re already giving separate worm treatments, the combined cost may be similar or lower.

NexGard Spectra vs Simparica Trio is the next comparison if you’re going down this path — both are all-in-one monthly treatments with slightly different worm coverage profiles.

---

Switching between them

No issue. You can move from Bravecto to NexGard or the other way around — just don’t overlap active coverage periods. Check with your vet if your dog is on other medications.

---

What vets typically recommend

Most NZ vets are comfortable with both and will prescribe whichever the owner prefers. In my experience, Bravecto tends to be the default recommendation for adult dogs with established weight — the convenience of quarterly dosing resonates with owners. NexGard gets recommended more often for puppies, dogs on other monthly medications (easier to sync), or owners who want monthly check-in discipline.

If your dog has a seizure history, note that all isoxazoline-class products (including both Bravecto and NexGard) carry an FDA advisory about rare neurological events. The risk is considered very low, but it’s worth discussing with your vet if your dog has any history of seizures or neurological conditions.

---

What about spot-ons and alternatives?

Both brands make topical (spot-on) versions with the same active ingredients. Same coverage, applied to the skin instead of eaten. Worth knowing if your dog refuses oral chews or has a sensitive gut.

Other flea control options include flea collars for dogs for long-term prevention and environmental treatments. If you have cats as well — I have to coordinate Pōhu’s flea treatment with Māui’s — check out our Best Flea Treatment for Cats in NZ guide since household flea control often requires treating all pets at the same time.

Bottom line

For most NZ dog owners, Bravecto is the pick — cheaper per month, quarterly schedule, and broader parasite coverage. NexGard is the better fit for puppies, owners who want monthly check-ins, or anyone building toward NexGard Spectra. Both do the job well. The only wrong choice is doing nothing.
