In this NexGard review, we look at what makes this monthly chew a popular choice for flea and tick control in Australia. If you’re weighing up convenience, coverage, and value, here’s what to know before you buy—plus how to choose the right product for your dog’s weight and lifestyle.
Important: This article is general information, not veterinary advice. NexGard is a chew for dogs only (not for cats). Always read and follow the label directions on the pack, including age/weight limits and any guidance for breeding, pregnant or lactating dogs. If your dog has a history of seizures/neurological issues, is unwell, or is taking other medications, speak with your vet before starting or changing parasite prevention.
What NexGard is and what it’s designed to do
NexGard is a vet-grade chewable flea and tick treatment for dogs, given on a monthly schedule. The active ingredient is afoxolaner (an isoxazoline). It’s designed to help protect dogs from common external parasites that can cause irritation and discomfort—particularly during warm, humid periods when fleas thrive.
In many parts of Australia—coastal Queensland summers, bushy NSW weekends, or milder conditions that still support year-round flea cycles—parasites can be an ongoing reality rather than a short season. A simple routine product can appeal to households wanting consistent protection without the mess of a topical application.

How it works (and why chewables suit busy owners)
Chewable preventatives are popular because they fit easily into a monthly routine—no parting fur, no residue on the coat, and no need to keep dogs separated while a topical dries. For dogs that swim, get bathed often, or spend time in wet weather, a chew can feel like the most straightforward option.
Practical household considerations matter too. If your dog shares the couch with kids, sleeps on the bed, or visits family, some owners prefer an oral product rather than something applied to the coat.
As with any parasite prevention, results depend on correct use. Give the product exactly as directed on the label and use the correct pack for your dog’s weight. If you miss doses or start late in the season, you may see ongoing fleas in the home environment because flea life stages can continue developing in carpets, bedding, and shaded outdoor areas.
Quick tip: Set a recurring phone reminder for the same day each month and pair it with a routine (like payday or dog-wash day). Consistency is a big part of making any monthly preventative worthwhile.
Pros, cons, and who it suits best
The practical takeaway from this NexGard review: it’s built for convenience and consistent monthly protection, which is exactly what many dog owners want. But the “best” choice still depends on your dog’s habits, health history, and your household routine.
Potential pros
- Simple administration: Many dogs accept chewables more easily than having liquid applied to the skin—especially dogs with thick coats or those that dislike handling.
- Works with active lifestyles: Useful for dogs that swim, get groomed regularly, or love muddy winter walks.
- Predictable monthly routine: Straightforward for busy families and multi-dog households.
Potential cons and cautions
- Not suitable for every pet: NexGard is for dogs only, and it must be used according to label directions for age/weight eligibility.
- Health-history considerations: Isoxazoline products (including afoxolaner) may not be the right fit for every dog. If your dog has a seizure history or neurological concerns, talk to your vet about the safest plan.
- Not a complete parasite plan by itself: Many dogs also need protection for other parasites depending on risk and location. Your vet can help tailor a year-round plan.
Who it often suits
- Dogs that spend time outdoors in grass, bushland, or tick-prone areas.
- Owners who prefer a low-mess, low-fuss option.
- Households that want a consistent monthly schedule and are confident they can give it reliably.
How to choose the right NexGard product for your dog
Most shopping decisions come down to weight range and pack size. Choosing the correct weight range matters—too low isn’t appropriate, and sizing up “to save money” isn’t a safe shortcut.
- Weigh your dog accurately: Use a recent weight (particularly for growing puppies and large breeds that can change quickly).
- Match the pack to the weight range on the label: Select the product that corresponds to your dog’s current weight.
- Stick to the monthly schedule: Build dosing into your calendar so you don’t drift or double up.
- Check suitability notes: Review label directions for minimum age/weight and any guidance for breeding, pregnant or lactating dogs.
Lifestyle risk also matters. Dogs that hike, camp, or visit off-leash bush areas may face more tick exposure than dogs that mostly stick to paved walks. In tick regions, it’s sensible to combine preventatives with good habits such as doing a hands-on coat check after bushwalks, paying close attention to the head, neck, ears, armpits, and between toes.

Alternatives and format comparisons (chews vs other options)
NexGard is one format: an oral chew. Depending on your dog and your routine, other formats may suit better, such as topical spot-ons or collars. The right choice often comes down to what you can administer correctly and consistently, plus practical factors like bathing/swimming and whether you have children or other pets in close contact.
It’s also worth recognising that parasite risk varies across Australia. Some regions have heavier tick pressure (including paralysis tick areas along parts of the east coast), while other areas may see more persistent flea problems due to climate and indoor living. If you’re unsure what’s most relevant where you live—or if your dog reacts to one format—your vet can help you choose a plan that matches local parasite activity and your pet’s health profile.
Is it worth it? A practical value check
Whether NexGard is “worth it” depends on how much you value convenience and reliability in a monthly routine. If you’ve struggled with topical applications, have an active dog that swims or is bathed often, or you simply want something quick to administer, the chew format can justify the spend.
Value is usually highest when you use it consistently and pair it with basic home and yard hygiene—because the environment plays a big role in ongoing flea pressure. If you’re dealing with fleas or trying to prevent a flare-up during warm months, combine prevention with:
- Regular vacuuming: Focus on skirting boards, under furniture, rugs, and pet sleeping areas.
- Hot washing pet bedding: Wash blankets and covers frequently, especially during humid periods.
- Yard maintenance: Keep grass short, remove leaf litter, and tidy shaded areas where pets rest.
- Routine checks: After park or bush time, do a quick coat scan and a hands-on tick check.
On the other hand, if your dog has very limited exposure to parasite-prone areas, your priorities may be different. The best value comes from matching the product to your real-world risk and using it as directed, rather than buying something “stronger” than you need or using it inconsistently.
Frequently Asked Questions
How quickly will I notice results after giving NexGard?
Timing varies based on your dog’s parasite exposure and the level of infestation in the environment. For the most accurate expectations, refer to the product packaging/label and your veterinarian’s guidance. If fleas are already established in the home (carpets, bedding, yard), you may still see activity for a period while you clean thoroughly and stay consistent with monthly prevention.
Can I use NexGard all year round in Australia?
Many households choose year-round coverage because fleas can persist indoors and ticks can be a risk in certain regions across multiple seasons. Your ideal schedule depends on where you live, your dog’s lifestyle, and local parasite activity—follow label directions and check with your vet if you’re planning a year-round program.
Can NexGard be used for puppies, or for pregnant/lactating dogs?
Follow the label directions for minimum age/weight requirements and any guidance regarding breeding, pregnant or lactating dogs. If you’re unsure what’s appropriate for your dog’s stage of life, ask your vet before dosing.
What if my dog refuses the chew?
Offer it with a small meal or make it part of a calm treat routine. If your dog won’t take chews reliably, a different format may be more practical—consistency matters more than choosing a product you struggle to administer.
