What It's Used For
- Flea prevention and treatment: kills fleas fast and prevents reinfestation for a full month with a single tasty chew
- Tick prevention (including paralysis tick): protects against all tick species found in Australia, including the dangerous paralysis tick
- Heartworm prevention: prevents heartworm disease caused by mosquito-transmitted larvae in a single monthly dose
- Mange treatment (demodectic and sarcoptic): treats demodectic mange (demodex mites) and sarcoptic mange (canine scabies) as well as ear mites

Ingredients and Active Compounds
Active ingredients (medium dog : 7.6-15kg formulation):
- Afoxolaner: 37.5mg (external parasite treatment and prevention)
- Milbemycin oxime: 7.5mg (heartworm prevention and intestinal worm control)
Afoxolaner works by over-stimulating the nervous system of parasites, causing death. Milbemycin oxime prevents heartworm by eliminating immature larval stages of Dirofilaria immitis and targets intestinal worm species.

Why Dr Jack Ayerbe Recommends It
“NexGard Spectra is the product I recommend when owners want one monthly chew that covers everything: fleas, paralysis ticks, mites, lice, heartworm, and intestinal worms. For medium dogs that spend time outdoors or in areas with tick activity, that consolidated coverage removes the risk of missed doses or conflicting treatment schedules. It aligns with infectious disease expert guidelines recommending monthly intestinal deworming, and simplifies compliance significantly. One chew, once a month, handles the full spectrum.”

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 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 Medium Dogs helps protect against a broad range of parasites in a single monthly chew. It kills fleas rapidly and helps control paralysis ticks, brown dog ticks, and bush ticks. It also treats mange mites including Demodex (the cause of demodectic mange) and Sarcoptes (the cause of sarcoptic mange), as well as ear mites and biting lice. In addition, its active ingredient milbemycin oxime helps prevent heartworm disease and controls intestinal worms including roundworm, hookworm, whipworm, and flea tapeworm. For more, Dr Jack Ayerbe covers dog parasite treatments in detail.
NexGard Spectra for Medium Dogs does not require a veterinary prescription and can be purchased directly from Vets Love Pets. While a prescription is not required, consulting your vet before starting a parasite prevention programme is recommended, particularly for puppies, dogs with health conditions, or dogs in high-risk paralysis tick regions.
NexGard Spectra for Medium Dogs should be given once every calendar month, year-round. Administering on the same date each month helps maintain consistent parasite protection without gaps in coverage. For heartworm prevention specifically, it is recommended to start dosing before the beginning of mosquito season, or as directed by your veterinarian. The chew can be given with or without food.
If you miss a scheduled dose of NexGard Spectra for Medium Dogs, give the chew as soon as you remember and then resume the regular monthly schedule from that new date. Do not give two doses at once to make up for a missed one. A gap in dosing may leave your dog unprotected against fleas, ticks, heartworm, and intestinal worms during that period, so contact your veterinarian if you are unsure about how to proceed after a missed dose.
NexGard Spectra for Medium Dogs contains two active ingredients, afoxolaner and milbemycin oxime, which together provide protection against both external parasites and internal parasites including heartworm and intestinal worms. The standard NexGard Chew contains only afoxolaner, which means it covers fleas, ticks, and mites but does not include heartworm prevention or intestinal worm control. Pet owners whose dogs require complete parasite coverage in a single product may find NexGard Spectra the more suitable option, though your veterinarian is best placed to advise which product suits your dog's individual needs.
