Talk to your vet before choosing a parasite product. Parasite prevention is a health decision. Paralysis ticks are a serious risk in parts of Australia and need prompt veterinary care, and the right product depends on your dog, your region and the season. Always follow the product instructions and your vet's advice. This is not veterinary advice.

01
Best all-in-one

NexGard Spectra

One monthly chew, and you’ve covered fleas, ticks (including the paralysis tick), heartworm and intestinal worms. It doesn’t do tapeworm, so add a separate all-wormer for that. For most dogs, though, this is the easy all-rounder.

02
Best for paralysis ticks

Bravecto

One chew that lasts up to three months on fleas and ticks, paralysis tick included, so there’s far less to remember through tick season. It sticks to fleas and ticks, so add a wormer and a heartworm product alongside it for full cover.

A monthly chew that covers fleas, ticks, heartworm and intestinal worms, and the per-dose price is genuinely competitive. If you want the full package without paying top dollar, this is a smart everyday pick.

9090/100
02
Bravecto$$$3-monthly tick & flea cover

A real standout if you live in paralysis-tick country: one chew gives you up to three months of flea and tick cover, so there’s far less to remember through the season. It sticks to fleas and ticks, so add a wormer and a heartworm product alongside it for the full picture. Scored by our independent review board against our published 100-point methodology, using publicly available information. Not veterinary advice.

Revolution Plus$$$Multi-pet (cat) households

Advocate$$Dogs who won’t take chews

Fleas, ticks & worms.

Fleas

Here’s the thing about fleas: most of them aren’t on your dog at all. They live in the home, in carpet, bedding and floor cracks, moving through a four-stage lifecycle. That’s why staying on prevention all year is so much easier than clearing an infestation once it’s settled, and why it pays to treat the house and every pet in it together. Wash the bedding, vacuum well, and keep all your pets on the steady schedule your vet recommends.

Ticks & the paralysis tick

On the east coast, owners take the paralysis tick seriously because it can make dogs very unwell, which is why proven tick cover is a priority in those regions. In tick season, run your hands over your dog every day in a thorough search, paying special attention to the head, neck and ears. Pick a product with established tick protection for your area, and if you ever find a tick or notice anything unusual, get in touch with your vet promptly.

Worms (intestinal & heart)

It helps to think in three buckets: intestinal all-wormers (roundworm, hookworm, whipworm), tapeworm, and heartworm prevention. Plenty of “all-in-one” chews handle fleas, ticks, heartworm and the common intestinal worms but skip tapeworm, so you’ll often still want a separate tapeworm or all-wormer step. Some routines lean on a dedicated heartworm product or an annual injection too — your vet can map out the simplest complete schedule for your dog.

Flea & worming FAQs

NexGard Spectra takes our #1 spot (90/100) because it’s the most complete single monthly chew for most Australian dogs: fleas, ticks (paralysis tick included), heartworm and the common intestinal worms, all in one dose. Bravecto is our pick for long three-monthly tick and flea cover, and Simparica Trio gives you the full monthly package at sharper value. The right product really comes down to your dog, where you live and the season, so run your choice past your vet.

Yes, indoor pets aren’t off the hook. Fleas hitch a ride inside on shoes, clothing and other animals, the mosquitoes that carry heartworm get in too, and ticks travel in from gardens and shared spaces. Staying on prevention all year is almost always easier and cheaper than clearing an infestation once it’s settled in. Your vet can point you to the right product and schedule for an indoor pet where you live.

NexGard Spectra, Bravecto and Simparica Trio all cover the paralysis tick, which is exactly why they rank so well for owners on the east coast. Bravecto wins fans for its up-to-three-month run, while NexGard Spectra and Simparica Trio fold tick cover and worming into one monthly chew. Even with a proven tick product, keep up a daily tick search in season, and if you ever find a tick or notice anything unusual, ring your vet straight away.

Both can be brilliant, and it really comes down to your dog. Chews like NexGard Spectra, Bravecto and Simparica Trio are easy to dose, can’t wash off, and several roll flea, tick and worm cover into one product. Spot-ons like Advocate are great for dogs that refuse chews, though Advocate doesn’t cover ticks, so you’ll want to pair it with a tick product in paralysis-tick areas. Your vet can help you match the format and the cover to your dog and your patch of the country.

Plenty of flea, tick and combination chews, including NexGard Spectra, Bravecto and Simparica Trio, you can buy from vets and pet shops without a prescription, though what’s on the shelf varies by product and state. Heartworm injections and a few specific treatments come from your vet directly. Since the dose hangs on your dog’s weight, age and health, it’s worth a quick chat with your vet to lock in the right product and schedule before you buy.
