NexGard Spectra is a monthly chewable parasite treatment for large dogs weighing between 30.1 and 60 kilograms. Each pack contains six chews providing six months of broad-spectrum protection. Suitable for adult dogs, it covers the full range of common Australian parasites in a single monthly dose — no spot-on, no tablet splitting.

Each chew delivers protection against fleas, paralysis ticks, brown dog ticks, ear mites, demodectic and sarcoptic mange mites, heartworm, and six species of intestinal worms including roundworm, hookworm, and tapeworm. The active ingredients are afoxolaner (for fleas and ticks) and milbemycin oxime (for heartworm and intestinal worms). Chews are beef-flavoured and designed to be accepted readily without needing to be hidden in food.

For owners of larger breeds who want year-round parasite protection without juggling multiple products, NexGard Spectra condenses what would otherwise require a flea treatment, tick prevention, and wormer into one monthly chew. The six-pack format suits owners who prefer to dose at the start of each month and move on.
