Why Dr Jack Ayerbe Recommends It
“Giant breed dogs need parasite protection dosed for their body weight, and pairing separate products is where owners commonly lose continuity. NexGard Spectra in the very-large band covers everything most Australian dogs need in a single monthly chew: fleas, paralysis tick, mites, lice, heartworm, intestinal worms. For working dogs and farm dogs over 30 kg that spend time in bushland, the convenience of one product is the difference between consistent year-round protection and missed doses. If your dog presents with sudden weakness, breathing difficulty, or wobbliness, treat it as a possible paralysis tick emergency and contact your vet immediately, regardless of preventative status.”

Awesome product
- SMLevel 2Sue M.Verified BuyerRated 5 out of 5 starsFeel confident in Nexgard Spectra to protect my dog's health
Nexgard Spectra covers tick paralysis, which I need, as unfortunately have a plaque of paralysis ticks at my place. Also heartworm, fleas, and many internal parasites as well. (But not hydatid tapeworm). Good to have the major parasite dangers which could kill my dog taken care of in one chew.

Love the price..only product used since our hunter was a puppy.
Why Choose NexGard?
NexGard is a popular flea and tick treatment for dogs that has gained a reputation for its effectiveness in preventing and treating infestations in Australia. Developed by the animal health company, Merial, in 2013, NexGard was the first chewable tablet to contain the active ingredient afoxolaner, a new class of insecticide called isoxazolines. This ingredient works by interfering with the insect's nervous system, leading to paralysis and ultimately death. Unlike traditional flea and tick treatments, which rely on topical solutions, collars or sprays, NexGard's chewable formulation makes it easier to administer and less messy for pet owners.
NexGard's ability to kill fleas and ticks within hours of administration, along with its long-lasting protection for up to 30 days, has made it a popular choice for pet owners in Australia. Before starting any new medication, it's important to consult with a veterinarian to ensure that it is safe and appropriate for your pet's individual needs.
NexGard Spectra: Complete Protection for Your Dog
NexGard Spectra is a tasty, beef-flavoured chewable tablet that provides complete protection against fleas, ticks, heartworm, and intestinal worms. It is proven to kill fleas before they can lay eggs, control tick infestations, and prevent flea allergy dermatitis. It also treats and controls hookworm, roundworm, and whipworm infections, and prevents heartworm disease. Safe for puppies as young as 8 weeks and for dogs weighing 2kg or more, NexGard Spectra is a trusted brand, recommended by all Australian Veterinarians, that is not only easy to administer and delicious, but also delivers comprehensive protection against common parasites.
Frequently Asked Questions
NexGard Spectra for Very Large Dogs is dosed for dogs from 30.1 to 60 kg. For dogs heavier than 60 kg, your vet may recommend combining two chews of an appropriate size band — never adjust dosing yourself without veterinary guidance. For dogs under 30.1 kg, use the size band matched to their current weight.
No. NexGard Spectra is available over-the-counter in Australia and does not require a veterinary prescription. We do recommend speaking with your vet to confirm the right size band based on your dog's current weight as part of a broader preventative care plan.
Once every month, given orally as a single chew. For year-round protection in paralysis tick areas of eastern Australia, monthly dosing should be continuous and not seasonal. Mark the same calendar day each month as the dosing day.
Only if they are 8 weeks or older AND weigh more than 30 kg. Most large-breed puppies don't reach this weight until 5 to 8 months of age, depending on breed. While they're under 30 kg, use the smaller-band variant matched to their current weight, then move up as they grow. Your vet can advise on the right transition timing.
No. NexGard Spectra covers roundworm, hookworm, and whipworm but does not include a tapewormer. Dogs at risk of tapeworm exposure (those that hunt, eat raw meat, or have flea infestations) may need an additional tapewormer such as praziquantel under veterinary guidance. For comparison with other parasite product combinations, see Dr Jack Ayerbe's guide to the best dog parasite treatments and preventatives.
